By the end of April this year, by the China Resources Comprehensive Utilization Association WPC, in the Composite Materials Committee organized by the China Wood Plastic Industry Development Seminar, WPC industry has become a hot topic. As the wood plastic materials discarded plastic recycling treatment in China is also a long-standing problem, has been the industry's concern, and wood-plastic materials will undoubtedly allow waste plastics to find the best way out.
Plastic has high strength and hardness, acid and alkali resistance, corrosion resistance, deformation, does not contain formaldehyde, can be a variety of cross-section shape and size, can retain good wood processing performance, but also to overcome the wood is not durable
While the plastic part of the material can be recycled as raw materials to reduce the amount of plastic waste generated, is becoming the plastic upstart in the family. Wood plastic materials industry originated in the United States in the 1980s. At the time, more and more waste plastics in the United States needed to be treated, and some wood fibers were originally used as plastic-modified filler materials because of their low cost and increased rigidity. Therefore, the earliest wood-plastic materials were treated as modified plastic. But with the wood-plastic composite material technology continues to break, and gradually produce both plastic and wood dual advantages of new materials, and its characteristics gradually appear, and become a class of self-contained new materials, rather than a certain type of material extension Or vassal, and ultimately the formation of a new industry. At present, various types of wood-plastic composite products in the United States, Canada, Germany, Britain, the Netherlands, Japan and South Korea and other countries have been more widely used, and the formation of more standardized industries and markets. China's wood-plastic industry has just started. According to incomplete statistics, is to mature, but the domestic wood-plastic industry from development to manufacture products less than l0 years.
The application of wood-plastic materials in China is still in the preliminary stage. Due to the limitations of technology, capital, equipment and marketing ability, most enterprises have a single product variety, low production efficiency, high production cost and poor quality stability. Fundamentally, and from the technical level or restricted the development of domestic wood-plastic industry. (2) the overall production capacity is not enough, the production line configuration is not ideal, especially the shortage of complete sets of products; (3) the low threshold of the market, resulting in a large number of small and medium-sized enterprises, Fourth, the domestic R & D institutions, manufacturers and manufacturers supporting the lack of interaction, can not provide support to each other, the majority of wood-plastic product quality is not high, and the type of single, many products are still clumsy, simple low-end materials, lack of market competitiveness; . At present, the National Development and Reform Commission has "wood-based composite technology development" classified as "industrial structure adjustment guide catalog (05) 20" to encourage projects. The State Council General Office is also the end of 2005 to the National Development and Reform Commission and other ministries issued a "speeding up the work on the conservation of wood and the views of alternative" requirements to strengthen policy guidance, increase technology.
