In recent years, with the increasing awareness of environmental protection and the depletion of global forest resources, higher requirements have been put forward for the use of wood. In this situation, the wood - plastic composite board [url=]Outdoor Anti-Skid Deck, Anti-Moth Fence Sales[/url], a new material which combines natural wood and synthetic plastic, has attracted wide attention.

Wood is a kind of porous composite material composed of cellulose, lignin and other organic materials. As an industrial material, it has the best environmental coordination and plays a very important role in the national economy. However, the wood has the disadvantages of being perishable, inflammable, susceptible to moth, low absolute strength, easy to absorb water and absorb moisture and cause large size deformation, which restrict the processing and application of wood to a certain extent.

According to resin experts, wood - plastic composite (WPC) is a kind of polymer (plastic) wood modified by impregnation of wood into polymerizable monomers, prepolymers, or mixtures of both, and by polymerization and solidification of impregnation components in the interstices of wood under the action of external energy. This material maintains the original texture and colour of wood, and the properties of hardness, compressive strength and abrasion resistance have been greatly improved, eliminating many inherent defects of wood, thus creating a new prospect for the efficient use of wood and the transformation of low-quality wood.
