3/4 vinyl composite lumber installation


Wood is a plant fiber as the main raw material, synthetic and plastic composites. At home and abroad have mushroomed in recent years, a new class of composite materials, mainly waste plastic and tree branches tree branches, rice husk, agricultural straw and other plant fiber as raw material, finished products are widely used for packaging, gardening, transportation, construction, home improvement, travel interiors and other places. Which combines the dual advantages of "wood" and "plastic", with environmental protection, waterproof, corrosion-resistant, pest control, fire-retardant, recyclable and so many advantages, it is a promising low-carbon, green, can be recycled "materials. about wpc material suppliers
Decades ago, the United States began to research and extrusion of wood-plastic composite materials, processing technology is immature, compared with plastic and pure wood products, there are a lot of performance deficiencies, wood-plastic composite material has not been rapiddevelopment. With the level of industrial technology breakthrough, the new process makes the use of wood-plastic composite performance greatly improve quickly open the wood products market.
Large-scale industrialization of wood-plastic composite extrusion began in the 1980s, with the rapid growth of the automotive industry, the ever increasing demand of automotive interior parts, followed by wood-plastic composites has maintained steady growth. With the market further explore mining, wood-plastic composite materials are increasingly used in real estate, public facilities and other aspects. In 1991, the international wood-plastic composites conference held in the United States. Wood-plastic industry in the 1990s, the decade, the United States has gained considerable development, the annual growth in more than 10%. about wpc panels suppliers
After more than 10 years of development, the United States had more than 50 per year in tons or more of wood-plastic enterprises, of which the largest companies listed on the New York Stock Exchange, the formation of a product development, raw material collection, equipment manufacturers mold R & D, finished products to a complete market marketing industry. The overall development of the European wood-plastic industry than in North America, but in recent years, to accelerate the move towards Wood-plastic small enterprises, production and technological level commensurate with Chinese enterprises, but powerful equipment manufacturing capacity, potential for development can not be discounted.
Europeans are relatively delicate requirements of wood-plastic material, variety of colors is also higher than the demand in North America, interior decoration and outdoor building go hand in hand, but the use of technology and commodity prices were not yet mature, there is a rapid growth of the space. Japan and awareness of environmental protection for geographical reasons, the use of wood-plastic material is more common than excellent product quality. WPC R & D institutions in Japan, after ten years of effort to develop high-quality wood-plastic material. Natural wood color and texture of its products have been widely used in housing construction and interior decoration, is one of the highest quality products in the world, represents a level of quality and trends of wood-plastic materials instead of natural wood. modulus of elasticity (moe) pvc
North America is the world's biggest WPC market areas, according to a special report, in 2001 only in North America, the annual supplies more than 320,000 tons. Is expected that the 2005 amount in 2005 will be more than twice that of the 2001 amount of double-digit growth rate. Among them, the United States has been at the forefront of the industry on R & D and marketing. The development of wood-plastic composite materials in Europe, strong growth in technology has reached coextrusion stage, has maintained a sustained growth in the furniture manufacturing industry, is about to dominate. In addition, the development of Japan in the international advanced level.
Three of China's WPC industry development history and current situation: double promotion encourage national circular economy policy and the potential benefits of demand, the rise of domestic WPC industry less than 10 years. The end of 2005, the National wood plastic enterprises around 150, most of these enterprises are behind the technical level, is still in the initial stage of the wood-plastic industry. As of the end of 2009 the mainstream domestic gathered in the wood industry chain enterprises has reached more than 300. Of particular importance is that under the joint efforts of all forces, the level of domestic wood-plastic materials / products manufacturing has leapt to the forefront of the world, made ​​of wood-plastic enterprises to conduct dialogue on an equal footing with the developed countries in Europe and the United States the right to.
With strong government promotion of social attitudes update WPC industry will be old. Of existing wood-plastic industry employing tens of thousands of people, the annual sales of wood products has been close to 10 million tons, annual output value of over 800 million yuan. Wood-plastic enterprises are concentrated in the Pearl River Delta and Yangtze River Delta region, the eastern far more than in the west. Technological level of individual enterprises in the east is more leading enterprises in the South occupies a number of products and absolute advantage of the market The test sample of the industry, on behalf of the enterprise has reached or exceeded the world's advanced level. Large enterprises and multinational corporations in some industries also pay close attention to the dynamics of China's WPC industry. 3/4 vinyl composite lumber installation
