Wood-plastic composite environmentally friendly materials
Wood-plastic composite environmentally friendly materials, the market prospect is broad
Renovation Many people now prefer to use wood flooring and wood furnishings, some of the new room wooden materials in three to five years after the tenants move, rot, wood crevices and even from time to time flies, ants drilled. A recent survey shows that according to the Ministry of Construction, the majority of buildings in cities after the completion of 3 years or so of the situation, while the termite traces of floors up to floor 35. At present, the the Termite housing construction area of about 3,000 million square meters, caused direct economic losses each year due to termites more than 1.5 billion yuan. To this end, more and more people began to use wood-plastic composites production of wood-plastic flooring, this will be a good solution to the flooring pest control, waterproofing, moisture and other problems.
So what exactly is the wood-plastic composite materials? Wood-plastic composites (called in the industry through WPC), also known as “WPC”, “eco-wood”, or “green wood” is wood chips and other primary biomass-based raw materials, the use of polymer interfacial chemistry principles and plastic filling modified the characteristics of plastic compounding a certain percentage of the base material, forming a reversible recycling of basic materials processing after a special treatment process. Wood materials including sawdust, wood shavings, bamboo sawdust, wheat straw, bran, coconut shell, bagasse, peanut shells, and marijuana. Plastic commonly used in PE, PP, PVC, PS and ABS, and other recycled plastic is widely used in wood-plastic composite materials. It is a cover a wide range of product categories, a variety of morphological structure and basic materials. While maintaining the appearance and texture of the wood, but also has good moisture-proof water-resistant, acid and alkali, antifungal, anti-static, anti-moth performance, and wood-plastic product fire performance, pollution-free, pollution-free, 100% recycle and reuse fully reflects the advanced concepts of sustainable economic development of circular economy and resource utilization.
With the continuous improvement of the environmental resources of the degree of attention to waste recycling and comprehensive utilization of resources circulation model of economic development as the core of becoming the main trend of world economic development. Vigorously develop the resource recycling technology will be economic development and environmental sustainability have a profound impact. The use of waste plastic and wood fiber production of wood-plastic composites products is in tune with this trend, in recent years gradually attracted the attention of the government and the public. Selection of wood-plastic material as some of the venues and facilities, the construction of special materials such as the 2008 Beijing Olympic Games, the 2010 Shanghai World Expo and Guangzhou Asian Games venue construction, increasing use of wood-plastic material.
Foreign wood-plastic industry in North America as the representative of the region is currently the world’s wood-plastic composite material of the fastest growing and the largest amount of market. In the past 10 years, the WPC market growth remained above 10%. WPC is a very young emerging environmental protection industry in China, has been in a period of rapid development since 2005. Domestic wood plastic production and R & D technology has improved steadily over the next 10 years, wood-plastic composite materials outside the architectural decoration and landscape industry will also be in the field of transport track, car interior parts and packaging materials will have a large number of applications.
According to related statistics, 70 percent of wood products for building and garden industry, as an important part of the building materials, and improve the detection of wood-plastic composite materials is of great significance. Standards system and regulations to regulate wood-plastic products, while China was released in April 2010, the national standard of two wood-plastic composite products, is GB / T 24137-2009 “wood plastic decoration board, “and GB / T 24508-2009″ wood-plastic flooring “. Wood plastic wide field of use, actual use of a lack of appropriate standards. Seen in this light, our country laws and regulations on wood-plastic material formulation and promulgation of the yet to be gradually perfected.
