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.
