Wood plastic composite material originated in North America, commercial production for more than 40 years, has gone through three stages, namely the first stage of production of ordinary Wood plastic composite Logistics Pallet-based; mainly the production of landscape construction materials and decoration materials the second stage and third stage of the main structural components and sets of intensive construction. Industrial development and promotion of the use of cheap or waste resources is a major feature and advantage of the Wood plastic composite industry. Broadly speaking, the Wood plastic composite has actually become a new class of materials with a variety of natural fiber materials or inorganic materials as the substrate, the composite made with a variety of resin materials. Its appearance is very conducive to ease the current shortage of resources, especially the protection of forest resources. Initial Wood plastic composite has been as a species of modified plastics, but with the increasing levels of production technology, its products, with the many advantages of plastic, wood, metal and other elemental materials, product features gradually apparent has gradually become a self-contained new material. It is a branch of the most dynamic in the new biomass in the composite family, and gradually formed to fill the polyethylene (PE), polypropylene (PP)-based structured products, and to fill polyvinyl chloride (PVC foam two branches) as the main decorative products. Industry practices and user needs, the direction of development of the two major categories of wood products tend to imitation wood products. But due to the strong plasticity of the Wood plastic composite, Wood plastic composite industry and related industries provide a wide symbiotic way.Wood–plastic composite decking lumber Wood plastic composite biggest features is that it also has the dual advantages of the basic materials of natural wood and resin material of two different materials, both with wood texture and performance (it can be sawed, planing, nails, bending and bonding), to overcome the poor stability of timber size, flammable, tide, perishable, easy to bore the growth of mold and other shortcomings, but also avoid the high temperature creep of pure resin material, low temperature brittle inadequate. For example, qualified wood materials 48 hours water absorption is generally less than 0.5%, with very good water resistance. Therefore, high-quality wood materials and its products, especially to adapt to the large temperature difference, the more water wet, poorly ventilated places such as Piazza, toilet, storage room, etc.. According to another timber expert determination: the average moisture content of wood below 19%, insects can not survive. But mixed with considerable part of the resin material, and low moisture content wood materials basic medium material and the living environment of the insect, moth performance is also very good. Wood plastic composite materials with diversity of raw materials, preparation of plasticity, the application of environmentally friendly, cost economy and recycling of renewable and many other advantages, especially to meet the low-value raw materials to produce high value-added products to maximize efficiency requirements, and thus more and more concern as more than the current national industrial policy to encourage the development of green industries. Plasticization and synthetic properties of the Wood plastic composite, and we its research limitations, pioneering the field of wood materials can be said that has just begun. Wood plastic composite may be some problems, we are confident that also has the ability to draw on relevant scientific and technological means to address them gradually from the processing of raw materials, technology and construction design. The good news is that a considerable number of friends in these areas, we have accumulated a wealth of experience, that wealth can help us to make a scientific adjustment for wood composite industry. Therefore, the Wood plastic composite industry out of the symbiotic way of a related industries will not be too distant prospect! Wood plastic composite board supplier
