<p>Currently there are two major wood-plastic processing technology. One is produced in the plastic modification, is the wood material as a plastic filler, external force or adhesive bonding wood material and plastic combined together. This technology has two key shortcomings hinder the great development of wood-plastic industry, one is not plasticized polar wood materials and non-polar plastic compatibility is poor, plastic and wood materials are not tight, resulting in decreased quality of materials; Second, the use of large proportion of plastic, wood effect is not ideal, high production costs, there is no price advantage, it is difficult to open the market. Another technique is wood modification, which is characterized by first using a specially formulated reaction initiator to initiate chemical reactions between the wood materials, to eliminate the polarity of the wood material as much as possible, deal with. Plasticization of wood-plastic material processing performance improved, the processing machinery requirements decreased, the use of plastic decreased, improving product performance while reducing production costs, thereby enhancing the competitiveness of wood-plastic products.</p>
<p>At present, China's domestic wood-plastic enterprises are mostly using the first technology, in urgent need of upgrading. Wood-plastic products because of its excellent performance, can be widely used in gardens, construction, furniture, packaging and other fields, but in the domestic market has not yet expanded. I believe that the expansion of wood-plastic market breakthroughs should be made from the following areas: 1 is the general wood products difficult to enter or to exit the field. Such as waterfront, outdoor construction, garden facilities, wooden packaging and trays. 2 is the field of choice now has a price advantage. Such as solid wood flooring prices are high priority areas; in the sand control, closing hillsides to facilitate afforestation, forest and other areas to be banned, the price of wood-plastic piles lower than the price of concrete piles; In addition, the polymer wood Of the highway, railway fence pillar price is much lower than the price of iron and steel piles; 3 is a special environmental requirements areas: such as home decoration, furniture if the use of wood plastic, you can achieve zero formaldehyde emissions should also focus on breakthroughs.</p>
<p>Therefore, the product application areas need to be broadened. WPC project as a good project benefiting the country, should be supported by national policy. Such as in Japan, each collection, use a ton of waste plastics, state grants 50,000 yen. Wood production of wood raw materials used in the processing of small wood materials processing residues, value-added tax should also be that is levy that is back. At present, the State Council has released the "development of circular economy views" and "on the conservation of timber regulations", but the specific support policies need to be released as soon as possible.</p>
