The Development of Composites Hollow Decking
Wood-plastic composites hollow decking is a new type of environmentally friendly composite material that has emerged in recent years, based on wood fiber or natural plant fiber as the reinforced phase, thermoplastics as the base, molten composite, using thermal pressure, extrusion, injection and other molding processing methods and made of a composite material. Wood-plastic composites are based on thermoplastics and wood fibers, which also determines their properties as plastics and wood.
Plastic wood composite materials into the rapid development period, plastic wood composite materials technology is also due to the development of the market and increasingly mature, especially in raw materials and mixtures, molding process, temperature control and cooling and formulation and other aspects of huge innovation, so that the development of plastic wood composite materials and raw material sources and product applications more closely linked, improve production efficiency and reduce costs. In the 21st century, people pay more and more attention to the green environment, building products and materials also pay more and more attention to its environmental protection, durability and sustainability, which makes composites hollow decking become an indispensable part of the field of architecture and decoration. At present, with the world’s plastic wood composite materials annual growth rate of more than 10%, the plastic industry has become the fastest-growing varieties. The advantages of plastic wood composite materials are lightweight, low water absorption, anti-termites, moisture resistance, dimensional stability and low maintenance requirements, the creep response and relative creep of plastic wood composite materials are significantly higher than natural wood, these advantages make plastic wood composite materials in the field of architectural decoration plays an important role.
Plastic Wood Composites Product Advantages
At present, the most popular products are paving, the production process for extrusion molding. Because plastic wood composite materials will not crack, nor warp, and beautiful appearance, in addition to paving, you can also do wall panels, ceilings, floors, decorative panels, building templates and so on. Its application field also from simple low value-added products, to complex high value-added products, gradually developed. Plastic wood composite products can also be decorative borders, fences, open-air tables and chairs, trash cans, etc., plastic wood products in the future are likely to replace PVC and other plastic products. In the United States, plastic wood composites hollow decking has been growing at a rate of about 10%, higher in recent years. In addition, Japan’s plastic wood composite material development in the world is also in a leading position, Japan’s lack of forestry resources, so that Japan’s plastic wood composite materials are more applied, and high quality, its appearance and natural wood are similar.
Japan has a large number of patents in the production and manufacture of plastic wood and has developed a number of special-purpose plastic wood products, such as anti-bacterial composites hollow decking, fungi in the environment corrosion of wood components and additives in plastic wood composites, destroying the material binding interface. Antibacterial plastic wood composite materials can be used in hospitals, clinic toilets and other places with bacteria, this material can effectively extend the life of plastic wood composites hollow decking.
Every year to consume a lot of wood and there is a lot of waste, in wood processing, 20% to 30% of corner material and sawdust wood powder is not fully utilized. In the case of a serious shortage of forest resources, a good way to maintain forest area is to develop plastic wood composites hollow decking, plastic wood composites can replace wood, the use of waste wood and wood powder or recycling to reduce the use of wood, thereby protecting forest resources. The development of plastic wood composite products conforms to the national industrial policy and the industrial development opinion of the comprehensive utilization of waste resources and is a new type of green material. The plastic wood composites hollow decking materials industry is environmental protection and energy-saving emerging industry encouraged by the state, which can reduce the serious harm caused to the environment by the incineration of agricultural and forestry waste, and can improve the comprehensive utilization rate of waste in agricultural and forestry production.
