wood-plastic products worldwide annual production

Domestic wood basic raw materials, which has existed for two generations: the first took the timber and data material, the second took the plywood, fiberboard, particleboard, wood pulp as the representative of wood-based panels. China's plywood production in 2003 has been ranked first in the world. The third generation of wood-plastic material, shine in the market, wood-plastic materials both plastic and wood both excellent performance, has an absolute advantage in the door material. Domestic wood-plastic market potential is huge, although only a few hundred tons of wood-plastic products worldwide annual production, but since 1998 in Europe and the United States and other countries each year to 65% increments. 10 Wood production enterprises, seven foreign manufacturers, and products for export. Chinese chemical materials testing department that the properties of the materials and environmental undergo a rigorous inspection to ensure that does not harm the interests of consumers. about composite lumber suppliers
Good mechanical properties, can be the same as wood sawing, planing, nail machining, with a hard, tough, durable, wear-resistant performance; formation of a large number of uniform and regular cell foam, can have to cost products. Experiments show that compared with the non-foamed PVC / wood flour composite extrusion foaming density can be reduced 50%, up to 0.6g/-1.0g/cm3. Uniform and regular cell structure passivation after foaming elongation at break of the crack tip can be remarkably improved. It is also a kind of eco-friendly materials, cheap raw materials, recyclable, reducing environmental pollution, and protect forest resources.
Garden online March 30: wood plastic as a new kind of green products, although in recent years become a hotspot of world attention and development, but a lot of wood-plastic domestic enterprises operating situation is not optimistic, and why? The author believes that the following three reasons. all weather wood plastic composite decking
First, production technology needs upgrading. According to the the China Forestry Economic Association Secretary-General Chen root length, wood plastic process, there are two main A plastics modification, the wood materials as plastic filler, force rely on external pressure or glued wood materials and plastic together. This technique has two key flaws hinder the development of wood industry, not plasticized the polar wood materials and non-polar plastics compatibility, plastic and wood material combination is not tight, leading to the decline of material quality; The second is to use a large proportion of plastic, wood effect is not ideal, and the high cost of production, there is no price advantage, it is difficult to open the market. A technique again is generated on wooden modified, and its technology is characterized in that the first reaction with a specially formulated initiator to trigger a chemical reaction between the wooden material, the polarity of the woody materials is to eliminate as much as possible, {TodayHot} Plastic pretreatment. WPC processing performance plasticizing treatment improved the processing machinery requirements reduce plastic usage dropped to improve product performance while reducing the cost of production, thereby enhancing the competitiveness of wood-plastic products. At present, most of the domestic wood-plastic enterprises is the first technique, the urgent need of upgrading.
The second is the need to broaden the field of product applications. Wood-plastic products because of their excellent performance, can be widely used in gardens, architecture, decoration, furniture, packaging and other areas, but to expand in the domestic market has not opened. I believe that the expansion of wood-plastic market breakthrough from the following areas: 1 general wood products is difficult to enter or exit the field. Such as the water's edge, outdoor buildings, garden facilities, wood packaging and pallets. 2 select areas now have the price advantage. Such as the high price of solid wood flooring, is preferential access areas; To ban areas in anti-desertification, closed forest, returning farmland to forest, wood stakes column price lower than the price of coagulation piles; addition, polymerization wood manufacturing of highway, railway fence piles prices far lower than the price of steel piles; areas with special environmental requirements: such as home decoration, furniture with wood, you can zero formaldehyde emissions, should focus on breakthrough . advantages composite lumber
Support policies to be introduced. Wood-plastic project benefits the country as a good project, and deserves the support of national policies. Such as in Japan, each collection, use tons of waste plastics, the state subsidy of 50,000 yen. The small material use of wood raw material of wood-plastic production is a small timber forestry processing residues, VAT should be immediately levy that is returned to. Currently, the State Council published the views of the development of recycling economy "as well as provisions regarding the conservation of wood, but the specific support policies need to be released as soon as possible. advantages composite panels
