100 housing units of 74 sets of high levels of formaldehyde inferior building material harm

July 10, Wuhan Evening News teamed Wuhan ranking will Kang Indoor Environment Test Center, one after another for the 270 residents preferential testing services. Yesterday, the company issued 100 sets a before detection analysis showed high levels of formaldehyde up to 74 sets, of which 24 sets are severe or more of pollution composite decking ratings 

wood and plastic composite

Formaldehyde in indoor air concentration of the national standard of 0.1 milligrams per cubic meter. 31 sets of 74 sets of high levels of formaldehyde room, the light pollution (concentration of 0.1 to 0.25 mg per cubic meter), 19 sets of moderately polluted (0.26 to 0.50 mg per cubic meter), high levels of pollution (0.51 to 0.8 mg per cubic 6 m), 18 sets of serious pollution (0.8 mg per cubic meter or more) sets.
Kang, general manager of Wuhan ranking shall Lihong Ling said housing formaldehyde exceeded outdoor terrace flooring, depending on the dosage of the plate, the quality of materials, wall treatment, furniture, quantity and materials as well as vacant ventilation time a combination of factors. Any of the indicators are likely to cause high levels of formaldehyde, each of the indicators are to the extent appropriate, may be substandard.
The survey showed that 74 sets of high levels of formaldehyde in the building, there are obvious features: extensive use of plate or wall, wallpaper paste, or placed in the cortex or inferior furniture or cabinets Edge incomplete. Among them, 24 sets of height and serious pollution of the housing 23 sets of vacant time does not exceed six months, eight sets of no more than three. Vacant shorter the time, formaldehyde is more easily exceeded.
On the contrary, in the 26 sets of standard rooms, 21 sets of simple decoration; 17 sets of place or residence time in more than six months, only two suites renovation finished in less than three months; modern wall panels wall paint brush only, or basement membrane technology to reduce toxic The amount of glue. Substandard housing formaldehyde, benzene and volatile organic compounds (TVOC) all the standards.
The medical profession generally believe that the long-term exposure to low doses of formaldehyde can cause a variety of chronic respiratory diseases, especially children with asthma, cause adolescents memory and intellectual decline, and reduced efficiency of healthy adults. Last year, the U.S. Committee to study the chemical poisons, formaldehyde or lead to leukemia, one of the culprits.

International timber the rate of reduction of the mainstream of the floor or lower prices

The wood floor is a resource-based industries affected by the financial crisis, international log prices there have been some decline, logistics costs will drop. Large cost reduction can lead to domestic products composite fencing panels, there are some down, so the past few years has been only solid wood flooring prices rise not fall downward trend this year may be.

wood plastic composite decking

The rise in the past, many owners in order to avoid losses, often not renovated the first book floor, fears that prices do not have to do this, and even later to buy the better. "Insiders such an analysis. Timber prices, the price of outdoor floor price fell, while relatively large declines may be paint, taking into account the international log prices has shrunk dramatically, many people are expected to paint the price is difficult to firm, while the wood-plastic composites are likely to act as the building materials market of new forces.
In addition, the "beautiful" is still pursued by many young people, the appearance of several "sell" products and personalized easy access to the market. Similar cabinet such products, the color on the breakthrough may lead the new trend, orange, grass green, dark red relatively conspicuous color will be more sought after.
In popular style, many designers that have prevailed for years minimalist style is still dominant in the home improvement market. The simple style of home improvement in the color still will be light color wood-plastic composite materials will be used more in the Home. A large area of the ceiling will gradually be people using the room wall layout is also light colored, outdoor flooring suppliers do not use too many complex designs, all in a simple, natural principle, wallpaper may be more use to consider to the popularity of minimalist style, soft decoration will be more important, so the cost of soft decoration may account for the renovation of a greater share of the total budget.

Ecological wood technology and standards

Ecological wood technology and standards lack of relevant standards is restricting our ecological wood the important factors. The United States material test association has developed the world in a land ecological wood product quality standard, ASTM7031,how to build a wood-plastic fence test method programs in 2004 approved as the production of ecological wood manufacturer guide.

wood and plastic composite

2005 years and has published ASTM D7032, it to building ecological wood and fence do the detail description. ASTM follow-up is for those who spread to more complex structure application field,wood plastic composite fence gatesby wood or other natural fiber manufacturing WPC set the standards.
Ecological wood
At present, most countries are not set up perfect standards of ecological performance test of wood, quality index, application scope are less supervision and management, it and ecological wood of the rapid development of the trend is not very symmetric.
So, different processing methods, application direction of conditions, formulate the corresponding product standards and technical standard, to standardize the ecological wood production,wood plastic composite rail fencepromote the popularization and application, so as to promote the development of the industry is very important.

Ecological wood with theoretical interface

The role of the ecological wood interface layer is to make the matrix and reinforced materials as a whole, and through it, transfer stress. In order to make the wood plastic composite manufacturers internal can evenly transfer stress, shows its superior performance, the requirements in the ecological wood the fabrication process formed a complete interface layer.

wood and plastic composite

Interface layer on the ecological wood much influence on mechanical properties, big wood plastic composite process  the intensity and rigidity to consider, interface with quite strong and compared to perfect is beneficial, it can obviously improve the transverse and tensile strength of the layers and shear strength, can also be an appropriate increase between layers of transverse and stretch film quantity, shear modulus.
For wooden fiber materials and plastic bonding is good, they will be allowed to stress in plastic and wooden fiber materials transmission between ontology. If, on the other hand, wooden fiber materials and plastic outdoor deck  exist between the bad interface, then affects the stress in the ecological transfer in wood, material in bear when outside force interface fracturing or stratification, cause of the composite material strength performance decline.
Therefore, a thorough understanding wooden fiber materials and the plastics substrate with the interfaces between the theory and help get combined with good ecological wood.

family compound wood production enterprise

From the China association of resources comprehensive utilization of wood and plastic outdoor deck materials professional committee to realize, in 2011, China's compound wood production more than 700000 tons. In recent years, with an average annual growth rate of more than 20%, and the mainstream production enterprise of more than 500 home, nearly 30% of products are exported to Europe and the United States. At present, our country has become the first big wood and plastic composite material producing and exporting countries.

wood plastic composite decking

"1025" period, along with our country a low carbon economy deeply, compound wood is adapted to the country's energy consumption and pollution reduction, the trend of circular economy, highlights the enormous potential.
In order to promote the development of wood-plastics composites, improve the straw, the utilization rate of waste plastics and crop waste, the national development and reform commission on December 10, 2011 issued a notice demanding "1025" period in the domestic build several compound wood industry base, support 4 ~ 5 home compound wood equipment production enterprise and 100 ~ 150 family compound wood production enterprise.
However, zhejiang a compound wood dealers said that at present export-oriented compound wood industry is facing unprecedented predicament.
By the debt crisis, 2011 years of industry exports fell sharply year-on-year, dealers also appear number down sharply.
Therefore, export enterprise gradually turned to the domestic main battlefield.
Facing the fierce competition in the domestic market, many compound wood production enterprises said the product diverse and series is the plight of the production and business operation dissolve the important way. Besides building materials, the enterprise to speed up the compound wood in interior decoration, furniture and other areas of application development.
More important, compared with the foreign and domestic quite part of  Wood plastic composite Markets remain relatively low in level, at present the main or in the outdoor stamped and landscape material is given priority to, in home outfit, furniture manufacturing and auto parts and other high-end application in the field of almost a blank.
And according to the personage inside course of study introduces, originated in Europe and the United States and other developed countries of the compound wood, at abroad are widely, mature technology, involved in the downstream building, decoration, furniture, logistics, packaging, garden, municipal, transportation and etc. People can not only at the outdoor villa, the pavilion, the green landscape, municipal facilities see compound wood figure, and in interior decoration materials, household, floor and other fields, wood and plastic composites are also consumers welcome.
In recent years, Wood plastic composite fencing materials  into the auto parts and other high-end applications. The German people even will it use the Benz, BMW, senior on cars, highlights the high-end trend of development.

Plastic wood industry in the spring

Plastic wood industry where the spring as a saving of the new materials and wood, after more than 10 years of independent development, compound wood is gradually developed into a new industry.
In recent years, domestic enterprise is accelerating wood plastic composite deckingin interior decoration, furniture and other areas of application development.
Especially in energy conservation and emission reduction in increasingly strengthen, the circular economy development momentum is the strength of "1025" period, has the raw material resources and products can be plasticizing, environmental protection renewable, etc of the advantages of the compound wood industry and adapted to the sustainable development of the trend, highlights the growing development potential.
According to information, with many new industries, compound wood industry is also faces a variety of difficulties at the early stage of the development, few varieties of wood polymer composite wall, standard are not perfect, customs code lack of factors of the development of the industry formed grip.
To shape for the future of the industry competitiveness, compound wood industry still have many problems to be solved.
To develop new applications
Compound wood is a imports, at the end of the 1990 s from North America in China. The material not only in performance on the set of the wood and plastic double merit, more important is the low carbon environmental characteristics significantly.
Research data shows, use 1 tons of wood and plastic materials, equivalent to 1.82 tons of carbon dioxide emissions, reduce 1 cubic meters of deforestation, save 80 barrels of crude oil, save BiaoZhunMei 11 tons.
It is because of the above characteristics with, compound wood as early as in the "eleventh five-year plan" period from the high attention. In 2008, the compound wood in the Beijing Olympic Games for the first time appear on and played with a beautiful beautiful public business card.
Later, wood and plastic composites in Shanghai world expo and the Asian games, guangzhou and other large public activity appeared frequently, once again and again to show the world the new material of elegant appearance.
The demonstration effect, greatly contributed to the compound wood industry development in China, but also from the state related management department attention.
Since the "eleventh five-year plan",composite wood products in the industry have more than 60 project won the support of relevant ministries.

Wood and plastic and normal wood difference

1, and volume, differences: the hollow structure of wood and plastic materials about a ton of 2-2.5 m? (30-35 m?) , usable volume close to 100%; Normal wood plastic composite manufacturers  logs were less than 50% of the volume can be used, the highest constructs fang mu only at around 70%.

outdoor deck

2, service life: in theory, wood plastic composite process  service life can be up to 50 years, at present foreign coverage wood and plastic materials use life has been up to 10-15 years; And at present domestic use of special treatment without using the normal wood outdoor products use fixed number of year general more than three years.
3, price comparison: wood SuZhi the market price of the finished product in an average of 10000 yuan of RMB/tons, according to the specific gravity, volume after conversion price for 5000 yuan/m? Or so; And at present medium material market price of wood in 6000-8000 yuan/m? Or so. If the profile material computation, wood and plastic domestic offer the highest is 350 yuan/m? , and wood profile common also is in 300 yuan of m offer? From top to bottom.
4, environmental assessment: anticorrosive wood, for example, the biggest problem right now is the environment and health hazards, China's current domestic using ICQ technology (i.e., low toxic anticorrosive) enterprise numbered, outdoor deck most of the products are exported to abroad; Using CCA technology (i.e. hazardous anticorrosive) products more and more get the constraints, such as the United States to ban the use of anticorrosive wood technology using CCA. And the use of wood and plastic materials to decorate, it can achieve "zero check in time" and achieve the purpose of green environmental protection, the negative impact on environment is almost zero.

Ecological wood price expensive?

Ecological wood price expensive? Ecological wood price is based on the quality of the goods quality to decide (here to remind you the consumers never covet cheap to buy quality more bad of the ecological wood products, the reason below we will have pictures about), but there is every ecological wood with each ecological wood plastic composite decking manufacturer brand price, good quality materials superior price relative to the picture is also there, the key is how to choose, and someone asked ecological wood is good, the key is also see quality.

wood plastic composite decking

Next, we will introduce domestic ecological wood the average price of the:
In this price, however, we need to try to understand the ecological composite wood products production of the main material is wood and plastic powder and plastic, wood and plastic powder is natural rice and paper industry by-products, the price is relatively cheap, and regeneration of transparent plastic particles of cheap plastic price for 17100-17300 yuan/ton, a little bit better PA66 level 1 transparent price for 21100-21600 particles yuan/ton.
Well we know the basic ecological wood basic price of raw material, production of human and ecological wood, water, and electricity plant a series of spending, we can work out a qualified and the best in quality ecological wood per square meter need at least 400-500 yuan, plastic mixed degree is less but ecological wood polymer composite wall comparatively thick middle-grade product price is 200-300 yuan/m2, if you buy the product price for ecological wood 100-150 yuan/m2 price, that should pay attention to the quality of products.

Wood and plastic raw material supply and the effective source of the development

Wood and plastic raw material supply and the effective source of development of the material by wood and plastic components. Among them, the woodiness material for the nature of WPC have an important effect on the performance of the product. The timber as raw material to produce the advantages of product is not only wpc decking good performance, and easy to ensure a steady supply of raw materials.

wpc decking

When the wood processing using waste wood, as raw material, need to pay enough attention to the purity of the raw material, degradation degree, especially to pay special attention to prevent metal, sand and damaged the problem of foreign processing equipment.In recent years, with various kinds of different natural fiber used in compound wood materials research a growing trend. More commonly used plant fiber raw materials for all types of flax, and other agricultural straw, rice, bagasse,.
Another important source is all urban plant fiber the outcast, such as waste paper, and waste textile, etc. The use of these materials, its supply, storage, dry make very important. The traditional grafting polymerization. The esterification, etherification, wood modification methods, although can reduce the polarity of the wood, wood plastic composite improve between compatibility, but cost often high, in economic competitiveness is not strong.
Wooden fiber materials is to improve the performance of the modified WPC important way, but the properties of modified method needs a new train of thought. Traditional methods in view of a large group of hydroxyl chemical conversion to, I'm afraid that this in theory have hard economic level, because of the need to use a lot of chemicals.
Biological and physical method, should be the focus of thinking. Increase in the amount of outdoor composite decking wooden fiber, can not only effectively reduce the cost, and will improve of forage woodiness feeling, it is more important for decoration materials. However improve wooden fiber dosage. Need not only in processing equipment, and additives in areas such as systems research, and wooden fiber the pretreatment of the raw material, modification and needs to be further research.

Wood into a build plank industry development direction

Wood into a build plank industry development direction wood plastic composite decking, is in recent years in China just pop up one of the products, wood and plastic floor is a kind of new environmental protection compound wood products, the waterproof, high environmental protection sex characteristics is the main points of products based on the market. Wood and plastic floor in into the domestic market then accept consumer attention, as consumers to enhance awareness of environmental protection, wood and plastic floor in the future the floor market of also will certainly become the mainstream market products.

Wood and plastic floor into building materials industry development direction
Compound wood is only appeared in recent years the new environmental protection building materials, in foreign countries is just the start. Wood and plastic products used the material available waste plastic and waste wood, agriculture, forestry, orange stem and other plant fiber for the base material, do not contain any plus the harmful component. And can be recycled again use, be called the true sense of the environmental protection, energy saving, resources recycling novel products.
Wood into a build plank industry development direction
As people to pay attention to the enhancement of environmental resources, to waste materials recovery and comprehensive utilization of resources as the core of the circular economy development mode has become the trend of world economic development. Develop resource recycling technology, the development of national economy and environmental sustainable development an impact. But using the waste plastic and wooden fiber production compound wood products is adapted to the requirement of good project.
Wood and plastic products in domestic market is not large area promotion, the Chinese market and North America than market, wood and plastic composites, and the growth of manufactured goods still a big space, expected domestic compound wood market in recent years more than one million tons of production will be in, the value of more than 1 billion yuan, and create a new composite wood products system.
Wood and plastic floor will be the future trend is in
For consumers, wood and plastic floor belong to energy conservation and environmental protection products, not only can be a very good control harmful emissions, also can do the ground wood polymer composite wall waterproof functions. For stylist, wood and plastic floor this new materials, have the affinity of natural lumber, and model, color various designers and innovative, can satisfy the design requirements of the prophet. For decoration company, it is easy to installation, greatly reduce the material cost of construction, artificial cost and time limit for a project cost. Time can not only improve the project vote advantage of the bid-winning rate, at the same time, and you had a chance to undertake more ahead of the other projects, for enterprise win more benefits. Products waterproof, moistureproof, anticorrosion, deformation characteristics can greatly reduce the maintenance service after the completion of the project cost.

As a kind of a large-scale promotion based materials

According to the above standards, mutatis mutandis, the United States if wood and plastic standards and implementation status (only two specific point to wood and plastic material and product standards), home of the existing wood and plastic standard is perfect, but why actual situation but not the desired effect? Released in 2004 and in the implementation of the "LY/T1513 · extrusion wpc deckingplate on several main data, for example, due to its performance testing numerical too low--static music intensity: quartile 20 MPa, bending modulus: frequency 1800 MPa, exterior wear-resisting: g / 100 r than 0.08, hold screw force: frequency 1000 N (board face), so that in the actual application of basic lost detection significance, few enterprise in the actual application with its as quality inspection standard.

 In the state standard of GB/T24137 · wood and plastic board "pointed out that" compound wood "is by the wood or rich in cellulose material as a basis for materials and plastic (also can be a variety of plastic) through the various machining processing technology from the composite materials. Standard not specify "wood or rich in cellulose material" of the proportion of the regulations, no "plastic (also can be a variety of plastic)" the content regulations. Just think if in 99% of the polymer with the 1% of the wooden fiber, does it also can enter the "compound wood" ranks? According to the American association of ASTM of compound wood definition comment, wood and plastic composites and "plastic wood" difference is compound wood must have more than 50% of the wooden fiber (weight ratio, the drying wood fiber content), and should not use "lumber fiber materials and thermoplastics...... in a certain proportion mix" vague expression (the GB/T24508 · wood and plastic floor "), don't set about plant fiber and plastic makings of the proportion of the regulations.

As a kind of a large-scale promotion based materials, wood and plastic industry in a variety of material and product standards (including detection method) is important, but for a long time, people regardless of compound wood/product construction the requirement of the specifications, this must be to say that is a great risk. To Beijing Olympic construction, for example, wood and plastic branch to the 2008 project construction and Beijing the Olympic forest park headquarters on compound wood demonstration project construction in the summary have wrote: the project time, materials comprehensive and construction level and other factors, the conclusion is engineering materials general is fair. Problems may boil down to: improper material, some outdoor composite decking building used indoor material; Poor construction, the work is not meticulous, connection coarse; Wood and plastic materials of low quality (about of the total amount of such a condition is less than 30%).

In the later wood and plastic materials application, the conclusion of objectivity been reflected. In fact, by the so-called in for "Olympic Games wood and plastic material low quality", the biggest problem is the construction standard and not material quality problem. For example, the Olympic forest park in Beijing this year the north and south sides, hundreds of trash can all replaced wood plastic composite material trash can. To this, the engineering management personnel is that, we never denied a wood and plastic materials in application merit, in the past for some problems in the construction, also is not a simple material quality problem.

Wood and plastic industry is perfect quality inspection standard

At present, China wood plastics industry completely in the sense of standards work system has not been formed, along with the national "1025 planning" the curtain slowly open, China wood and plastic industry facing precious opportunity of development and the important strategic choices of challenges. According to information, wood and plastic industry in China quality inspection standards and implementation has many problems--the development of the industry standard, organizations need to participate in, the professional level uneven...... In the face of such situation, industry insiders is mixed.
At present have been announced and implement domestic wpc decking  national standards are "the GB/T24137 • wood and plastic board" and "the GB/T24508 • wood and plastic floor" two, industry standards are "the LY/T1513 • extrusion wood and plastic composite plate", another by guangdong promulgated "compound wood technical conditions" and "the compound wood inspection and test method" and so on the local standards.
Some informal standards are should bocog to wood plastic board drafting committee by the Beijing Olympic projects wood and plastic composite plates/profile quality testing technology guide ", by China's building standard court and wood and plastic branch of the editor of the compound wood construction field application technology guide • stamped ", and so on. Ordered, careful DaiPi or has already completed the project are drafting wood and plastic standard is the state forestry administration have the compound wood product physical and mechanical performance test "(national standards), association of industry of Chinese forest products of the compound wood test" (national standards), led by nanjing Linda the plastic wood composite material product physical and mechanical performance test "(national standards), wood and plastic branch of.
The wood and plastic with fiber materials", "the compound wood base material of physical and mechanical performance evaluation method" (work of letter industry standard), China's building standard editor of the "building wood and plastic composite board application technology regulations (construction standards of the ministry of construction) and the compound wood construction field application technology guide • wallboard", and so on. It is reported, there are still a few department and wood plastic composite industry the relevant standards in DaiPi report.

Use this process of material is made

From forming mechanism to see, one kind is physical molding. That is the use of hot sex adhesives. In the forming process of plastic and wooden powder will stick together; Another kind is the physical chemistry to shape. That is, through adding additives. In the pressure and temperature control. Make raw material with relatively low molecular mixture additives into the state of the polymer with reticular fiber materials. Use this process of material is made. The internal structure is completely after fusion of the molecular structure of rebirth network, more than any other process production of wpc decking products, compressive flexural strength, impact resistance is better.

wood plastic composite

At present wood plastic composite materials is under good advantages: (1) easy to processing. wood plastic composite materials with polyester and fiber. So has the same wood similar processing performance. But saw, can nail, plane. Use the woodworking tools to finish. And unmatched grip is much better than other synthetic materials: (2) high strength, good durability. Wood plastic composite materials has good elasticity modulus. In addition, because the wood fibers and contains resin curing. Thus has hardwood quite under pressure with, impact resistance and physical and mechanical properties, and its durability is obviously better than ordinary woodiness material: (3) water resistance, corrosion resistance. Wood and plastic materials and products can fight strong alkali. Water resistance, corrosion resistance. And not multiply bacteria. Not easy quilt bug eat by moth. Not long fungi: (4) can be adjusted the gender is strong. By adding different additives, polyester can polymerize, foaming, curing, modification and change. And then changing the density of wood and plastic materials, such as strength properties. Meet anti-aging, antistatic, flame retardant special requirements such as: (5) the sources of the raw materials widely. Plastic lumber products in addition to using a number of additives outside. More than 95% of all raw materials for polyester and wooden fiber. Its source widely, low price.
Wood and plastic materials used in packing industry is mainly a tray, the boxes and container vessels, etc. Only to the tray, for example, at present. North America as high as 200 million each year more tray dosage; Japan tray dosage in about 6 million a year. It is predicted that in the next few years in wooden pallets average usage may break through 20 million. So there's a big market in domestic demand.
Wood and plastic material is resistant to moisture, insect-resistant eat by moth etc, and is suitable for the storage industry use shelves, sleepers, stamped shop floor beams, etc. In our country's storage industry application plastic wood plastic board manufacturer, though just beginning. But demand is rising rapidly.
Wood and plastic material made of the pavilion, seat, flower POTS, trash is waterproof, moistureproof, corrosion features. And long life and low price; With wood plastic composite materials floor production houses, outdoor, sun room, dock, guardrail etc. Product has set up a file in the foreign beginning. Another. Application compound wood development, car interior trim, composite pipe, railway sleepers, cable protect tube, manhole cover, etc. Are also from demonstratable stages step into the application testing phase, believe that in the near future, wood and plastic product applications will still further.

Wood plastic composite(WPC)

Our country economy and in the lumber of efficient utilization of policy guidance made gratifying achievements Along with our country economy the sustainable development of the society, the contradiction between supply and demand of WPC deck for road side is more and more serious. In order to meet domestic timber demand and maintaining ecological safety, the government adopted an "open source" and "throttling" and the policy. "Open source" is vigorously conduct afforestation activities, encourage import wood and its composite wood products; "Throttling" is to save and efficient use of wood.

 In recent years, our country government has issued the wood encouraged conservation and efficiency of policies and regulations. Mainly has: First, "the general office of the state council on forwarding development and reform committee and other departments on acceleration of wood to save and alternative work of opinion notice.

One clear requirements focusing on four aspects: (1) work development of efficient and WPC deck for private house processing industry, improve the efficiency in the use of wood resources. (2) Implementation of wood protection technology, extend the wood products use period. (3) Establish a waste wood recycling mechanism, realize the timber resources recycling. (4) Development of alternative wood polymer composite wall, wood consumption structure optimization.
 Second, the law of the People's Republic of circular economy promotion law "(on January 1, 2009 implementation), among them clear to encourage and support the development of circular economy science and technology research, development and promotion, encourage recycling economy publicity, education, scientific knowledge popularization and international cooperation.

The state shall encourage and guide citizens with saving energy, saving water, saving material and in favor of environmental protection products and regeneration product, reduce the amount of waste and emissions. The people's government at or above the county level and the competent forestry authorities shall actively developing ecological forestry, encourage and support the forestry producers and related enterprise USES wood plastic composite decking manufacturer to save and alternative technology and develop forestry waste and time firewood, small Shasheng shrubs and comprehensive utilization, improve the comprehensive utilization of wood.

Third, "the general office of the state council on acceleration of comprehensive utilization of crop straw opinion" (countries do hair [2008] no. 105), of which clearly to actively develop the straw as raw material to the processing industry. Encourages the use of clean production techniques, the production of raw materials to stalk the wood pulp. Guide to straw as raw materials development man-made plank, packaging materials, such as tableware products production, reduce use wood.

wood powder

Wood plastic composite materials is waste plastic, wood powder (such as wood, bamboo powder, rice straw infarction, etc) as raw material, according to certain mixing ratio, and add a special additives. After the high temperature and extrusion molding process, made of a new type composite materials. Its good performance, the versatility, beneficial to the environment, have good prospect, and develop the promotion.
Wood plastic composite materials processing technology and performance characteristics
Wood plastic composite products are the technical features of the two kinds of greater difference between different materials mixed with each other. Is made of wood and plastic composites  2 for one.
Wood powder (or the crops the fiber powder) as a kind of organic plastic packing has source, low cost, widely low density, good insulation and many other inorganic packing can not reach the high performance, but it is not like inorganic packing that widely used. The main reason is that: one is the matrix resin and the compatibility of a poor: two is melting in the thermoplastics spread among poor effect, causing poor liquidity and extrusion processing difficulties. Because the main components in the wpc decking powder is cellulose. Contains a lot of hydroxyl, these hydroxyl form hydrogen bond between the molecules or molecular hydrogen bond wood powder has made in the water. And very strong polarity. And most of the thermoplastic the polarity, with water flow, so the compatibility between the poor, the interface of the sticky relay is small, need through the additive modified plastic lumber products and the surface of the wood powder. Increase the affinity of the interface between them. The properties of modified wood powder has enhanced nature, it is able to transfer between packing and plastic board  stress, so as to achieve the function of the reinforced material strength.
Extrusion molding, hot pressing molding, injection molding wood plastic composite materials processing is the main forming method. Because of extrusion processing cycle is short, high efficiency so extrusion molding method is a kind of relatively common process line.
From plastic wood manufacturer to see, there are mainly of the following categories: according to the raw material to points, kind of use plastic raw materials for the pure plastic or commercial level plastic: another kind is to use single composition has certain characteristics of waste plastics. According to the processing technology to points. One kind is two steps ChengXingFa. That is plastic and wooden powder mixed directly after forming process.

wood and plastic production

Wood and plastic industry in our country is in the ascendant, along with growing industrial scale, due to material can't from the steady supply of expanding production, which has gradually appear in wood and plastic production enterprise before.
In the current wood and plastic production, although the enterprise in the production requirements for their raw material supply to the many way, also have each know-how, but in wood and plastic materials standardization popularity before, but it also seems to have no man can do than the wood plastic product  the following three aspects of the restriction:
Wood and plastic materials in the production of the main factors
1, wood and plastic application materials (polyolefin type) of waste
Although wood and plastic industry had the very big development, but digestive waste plastic and not plastic wood manufacturer must undertake in the future of the responsibilities and obligations, in other words: wood and plastic industry can not dependent on waste plastic and survive. But for the moment, the cost and process and wood and plastic materials application scope factors, waste plastic is still wood and plastic production of raw materials with first. But domestic waste plastic recycling source, processing by uneven behind, processing technology and marina deck materials/wpc decking itself on a smaller scale, and many other constraints, it is difficult to form the standardization, the scale plastic wood manufacturer chain.
2, wood and plastic production process of secondary pollution and high energy consumption
Because of the quality of raw wood plastic limit and end products many kinds of requests, wood and plastic production process, especially in the raw material processing and mixed in the process of mixed refine add accessories composition is overmuch, some wood and plastic materials production enterprise secondary pollution is obvious; At the same time, from the power consumption of wood and plastic production accounts for the costs ratio see (compared to pure wpc fencing project processing and plant fiber products processing), the current wood and plastic composite material production more for high energy consumption.
Therefore, the expansion of wood and plastic industry scale, improve product quality, wood and plastic expand wood and plastic materials application field, reduce the wood and plastic production of secondary pollution and high energy consumption, urgent need we make wood plastic raw materials on the production of professional intensive specialty road.

wood-plastic industry

At present, the full sense of the Chinese wood-plastic industry standard-setting work system has not been formed, slowly open the curtain with the national "12th Five-Year Plan", the Chinese wood-plastic industry faces the challenge of valuable development opportunities and a major strategic choice. It is understood that the formulation and implementation of the quality of wood-plastic industry testing standards there are still many problems --- the development of the industry much-needed norms, competing participation of various organizations, professional standards is mixed. Faced with this situation, the plastic wood manufacturer can be described as mixed .

Wood Plastic News—plastic wood manufacturer

According to experts, in the next few years China wood plastic composite products industry scale will be 30% a year on average-50% of the speed of growth, and eventually the market will have a capacity of 10 million tons per year, the annual output of more than 50 billion Yuan.
Our country has wood plastic composite wall panels  production 170 enterprises, the annual output of more than 1.2 billion Yuan, is the world's second largest producer. But the industry standard is still a blank, because some enterprise in order to reduce the cost will have the toxicity of waste plastic polyvinyl chloride (PVC) as the main raw material production; make originally green environmental protection plastic lumber products become toxic products.
European plastic wood industries in recent years have to speed up the trend. Wood plastic composite product  are recycling waste wood and GanZheZha and waste, and recycling waste plastic to certain mixing ratio, add a special processing AIDS, by high temperature extrusion of a kind of environmental protection into complex materials. Germany between 2004 and 2005 is doubled.
The United States plastic wood market 2005 annual output reached more than ten thousand tons, is the plastic wood manufacturer production and consumption number one superpower. It holds concurrently at the same time wood and plastic double characteristics, avirulent environmental protection, in normal outdoor environment of service life is general of natural plastic lumber manufacturers 5-10 times.
At present, the North American plastic wood composite panel  demand for years about 700000 tons, annual average growth expected future years will be more than 15%. Plastic wood composite material is a country such as the United States, Canada, Australia, Germany, etc in green energy conservation and environmental protection products, is strongly support.
