WPC new material has high strength and hardness, acid, corrosion, deformation, formaldehyde-free, easy recovery, can be made of various cross-sectional shapes and sizes, not only retains the advantages of wood processing performance, but also overcome the wood is not durable, afraid disadvantage moth-eaten, now is becoming the new darling of the international and domestic building materials market, it can form a huge new industrial system.
Economic double prominent environmental effects, WPC has more environmental effects and economic advantages: first, the protection of forest resources. WPC is made of plant fibers and plastic composite material consisting of mixed material. Ecological wood installation life and defects Among them, the woody fibers such as sawdust, wood shavings, sawdust, bamboo and coconut shell and other debris, herbaceous fibers such as wheat straw, cotton stalks, stalk, bran, soybean hulls, peanut shells, cotton stalks, sunflower stalks, bagasse, etc., are low-value waste of natural resources, after screening, crushing, grinding and processing technology, it becomes wood wood raw material. Plastic raw material for wood processing may be a thermosetting plastic, such as phenolic resins, amino resins, epoxy resins, etc., can also be a thermoplastic. Additives commonly used plastic products mainly solubilizer, coupling agents, lubricants ,, coloring agents, anti-agents, UV stabilizers, these materials are non-toxic and harmless to humans and the environment of the material. It is understood that the total amount of waste plastic per year up to 70 million tons more than 200 years after waste plastic in landfills to decompose is complete, and the decomposition process will generate toxic substances, causing damage to the soil; our country there are about 600 million tons per year more than straw to be treated, handled mostly burned serious air pollution, and even affect the normal operation of aviation. WPC new material from the use of raw materials point of view, can alleviate the "white pollution" problem to some extent, can also ease the problem of air pollution caused by burning waste straw.
