With China's continuous emphasis on environmental protection and the continuous improvement of people's environmental awareness, in recent years, the continuous development of the environmental protection industry, people's requirements for environmental protection have become higher and higher. Plastic wood, as a new environmental protection material, plastic wood materials in the field of home improvement The market development status is getting better and better, and the development prospect of the plastic wood material market is getting wider and wider. Predicting the application situation at this stage, the plastic wood will replace the solid wood flooring commonly used in home improvement in the future, becoming one of the key directions of development .
China's development of plastic wood material industry is of great significance to environmental protection
China is a country with poor forest resources. In 2009, China actually used 320 million cubic meters of wood, of which the gap reached 140 million cubic meters. In the case of a serious shortage of wood, an effective way to increase the forest area is to achieve wood replacement. In wood processing, 20% -30% of wood flour and scrap are not fully utilized. The use of recycled plastics, waste wood powder and other wood-plastic products through technological innovation can not only replace wood well, alleviate the shortage of forest resources, increase forest carbon sinks, achieve carbon dioxide emissions reduction, but also reduce the increasingly serious "white pollution". Social and economic significance.
Raw material sources of plastic-wood composite materials in China
Due to the improvement of production and living standards, wood processing wastes such as wood chips, wood shavings, corner wastes, and a large number of crop fibers such as straw, rice bran, and nut shells, which have been used for burning wood in the past, have been seriously wasted Large destructive impact. According to statistics, the amount of waste wood powder under the wood processing house in China is several million tons per year, and the output of other natural fibers such as rice bran is over ten million tons.
At the same time, the application of plastic products in production and life has become more and more extensive with economic development. The problem of white pollution caused by improper disposal of plastic waste has become a major environmental problem. Relevant figures show that plastic waste has accounted for 25% -35% of the total garbage in urban waste. In China, the urban population generates 2.4 million to 2.8 million tons of waste plastic every year, which has become a serious burden on the sanitation department. If the waste plastic products can be effectively used, it will have a huge promotion effect on environmental protection and economic development.
Development status and prospect of plastic-wood composite materials
Plastic wood profiles have many advantages, but in our daily life, we rarely see this material, what causes this situation? One is that the promotion is not strong enough, and another important reason is the price. It is expected that it will not exceed 10 years. The plastic wood flooring will definitely replace the current ordinary solid wood flooring.
The development status and prospects of the plastic wood material market are not only widely optimistic in China, but also optimistic all over the world. We believe that this is not only because the product itself has excellent characteristics, but also because it is determined by its resource recycling and its important significance to the environment.
