Now wood plastic composite materials are becoming more and more common in our lives. Not only in our country, but many other countries have developed the wood plastic industry to produce wood plastic composite materials. The quality of wood plastic composite materials has beaten many other materials, and now many countries The requirements for environmental protection are getting higher and higher, which is why more people buy wood plastic composite materials. Let’s take a look at the introduction to the prospects of wood plastic composite materials today.
Wood plastic composite materials (WPC for short) is a new type of composite material that has flourished at home and abroad in recent years. It refers to the use of polyethylene, polypropylene and polyvinyl chloride instead of the usual resin adhesives, and it is combined with wood flour, rice husk, straw and other wastes. Plant fibers are mixed into new wood materials, and then subjected to plastic processing techniques such as extrusion, molding, and injection molding to produce plates or profiles. Mainly used in building materials, furniture, logistics packaging, indoor and outdoor decoration industries. A board that is formed by hot extrusion after mixing plastic and wood powder in a certain proportion is called an extruded wood plastic composite board.
A 2003 study by a consulting company in the United States showed that there was a total demand of 600 million kilograms of wood plastic composite materials in the North American and Western European markets, and North America accounted for 85% of the total demand. Building materials such as floors, handrails, doors and windows account for 80% of the demand for wood plastic materials in North America. In North America, other major market applications are floor paving (boardwalks and platforms), automotive components (car dashboards and spare tire covers), and industrial and civilian consumer products (tables, park benches, and pads). The same survey in Western Europe shows that automotive materials account for more than half of the demand for wood plastic composite materials, while construction materials account for 30% of the market. The annual growth of wood plastic composite materials in North America and Western Europe is expected to be 14% and 18% respectively by 2010.
Wood plastic composite materials are also popular in Asia, especially in Japan, where the application of wood plastic materials in platforms, floors, walls and interior furniture is becoming more and more popular. China is a country with poor timber resources. The forest coverage rate is 12.7%, which is only 61.3% of the world's forest coverage rate. The per capita forest stock is 10 m3, and the per capita forest stock is only 12 of the world's per capita stock. 5%, the per capita wood consumption level is less than 0.05m3/year, which is lower than the world average of 22%. For this reason, our country imports about 10 million m3 of wood every year. Coupled with long-term unreasonable development and utilization, the forest area is declining at an alarming rate, and the usable wood resources are declining. While the situation that the total consumption of forest resources is greater than the total growth is becoming more and more serious, the quality of forests is declining year by year, especially the accumulation of natural forests and mature and over-mature forests has declined sharply. The recoverable resources are on the verge of exhaustion, and the resource crisis is obvious. Intensify. According to statistics, every year, 756×104hm2 of forested land in the country is converted to non-forested, sparsely forested or shrub forest land, and 44×104hm2 of forested land is turned into non-forestry land. The situation is very severe. In this case, how to make full and effective use of limited timber resources, protect the environment, and serve the society has become an urgent problem to be solved. Wood plastic composite material was born under such circumstances. Because it is an environmentally friendly material, its appearance will find new ways for the effective and reasonable utilization of waste wood and plastic. Although the current consumption is not large, it is believed that replacing PVC and other plastic products with wood plastic composite materials will grow as rapidly as the replacement of wood products by plastic products in the past.
Because wood plastic composite materials have many advantages incomparable to pure wood and plastics, they have received extensive attention at home and abroad. The material is a green and environmentally friendly material, which can recycle low-cost waste wood and plastics. The wood plastic composite material produced by this technology can be used as a substitute for wood, which can effectively alleviate the contradiction between the shortage of forest resources and the shortage of wood supply in China.The production technology of wood plastic composite materials not only meets the needs of the country's economic development, but also meets the country's industrial policies, and the products are used in a wide range. Therefore, it can be believed that wood plastic composite material is a material with great development prospects, and it is also an innovative technology with vitality and market development prospects. It has broad market prospects and good economic and social benefits.
Through the above introduction to the prospects of wood plastic composite materials, we have all found that wood plastic composite materials as a green product have played a great role in our environmental protection. In the future, I believe that the wood plastic industry will develop better and better.
