Basic knowledge of wood materials in Chongqing City for three Building Materials Co., Ltd - WPC (WPC), the full name is Wood-Plastic Composites is a new material in today's world, many countries gradually promote the use of, it is PP, PE , PVC and other resins or recycling of waste plastics and sawn wood, straw, rice husk, corn stalks and other waste through the application of science and technology equipment compounding formulations granulation or direct extrusion process made by a variety of profiles . Judging from the look and feel of Sichuan wood siding, wood material has good wood texture, moisture, color is good, thermal insulation corrosion, mechanical properties than pure wood high 10 times, is an ideal substitute for natural wood . Products made of this material can be widely used in packaging, gardening, transportation, construction, furniture, home improvement, travel and other areas of the interior. And in addition to the plastic waste, one ton of wood-plastic materials have 50-90% of the material can be derived from wood fiber straw. Currently, Sichuan wood manufacturers, producing wood plate mainly in the following three kinds of process routes: one extrusion process. By a single or twin screw extruder molding, any length can be continuously extruded sheet. The process can be divided into single and dual extrusion composite extrusion sheet, composite extrusion is aimed at the appearance of wood plate coextruded layer of pure plastic surface, become wood plate can be used for special occasions. Second, the thermoforming process. The process can not continuously forming certain specifications sheet Sichuan wood, MDF molding process is similar. Third, the extrusion process, that is a side extruder and extrusion press in combination with side pressing process. The molding process is longer than the length of the sheet thermoforming sheet length, and its overall performance is better than the product sheet extrusion products. Long three wood industry and the overall situation of China WPC WPC has been good in the world today in many countries to gradually promote the use of new green materials. Currently the world's demand for WPC is increasing, global output has more than 1.5 million tons, of which the North American production of about 1 million tons, about 200,000 tons China, Japan and nearly 10 million tons. German WPC amount has been more than 70,000 tons, a leading position in Europe. In China, the WPC material is a very young and emerging environmental industry, from 2005 onwards has been in a period of rapid development. Application WPC also more widely, including windows and doors, insulation systems, park benches, garden sheds and tower building solar screens, and other cellulosic materials including wood flour agricultural products. At present, the amount of Chinese WPC average annual growth rate of up to 30%. With domestic production of wood-developed technology has improved steadily over the next 10 years, except at WPC architectural and landscape industry, but also in the field of rail transportation, automotive interior parts and packaging materials will have a lot of applications. 2015 Chinese wood demand will reach 30 billion yuan. A huge market space. Sichuan wood door manufacturers, long three-wood building materials plant (certified), Sichuan, Chongqing wood provided by three years of building materials Limited. Building Material Co., Ltd. Chongqing City for three (www.cqjsmsjc.com/) Chongqing Liangping, materials processing leader, over the years, the company implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. In the three years leading building materials with the staff warmly welcome all inquiries negotiations to create a long three building materials, a better future.
