With the accelerated pace of life, life is to facilitate the development of biochemical development, in order to comply with this demand, disposable foam lunch boxes, plastic bags, chopsticks, cups and so began to frequently into people’s daily lives. These easy to use, low prices The emergence of packaging materials to people’s lives has brought a lot of convenience. However, these packaging materials are often discarded after use, resulting in white pollution, resulting in environmental hazards, causing great environmental problems. At present, plastic waste handling measures are mainly landfill, incineration, simple regeneration, resource technology. Plastic acid, alkali, weather resistance, easy to break down and other characteristics, determines its final disposal should not be buried. Incineration not only releases toxic chemical gases that threaten human health, but also produce hydrogen chloride gas that can lead to increased acid rain. Simple recycling plan will be recycled plastic sorting, cleaning, crushing, granulation after the direct processing molding, the performance of its products deteriorated, will cause pollution and damage to the environment. Resource-based technology is divided into two categories, one is a variety of waste plastics recycling and recycling technology. The other is for different varieties of waste plastics using different recycling technology. Compared to other treatment measures, resource-based technology is the most desirable way to deal with waste plastics. The use of waste plastic to make wood-plastic composites has become a new way of garbage disposal of plastics.
Wood plastic, that is, wood-plastic composite materials, refers to the use of PE, PP, PVC, etc., instead of the usual resin adhesive, and a certain percentage of wood flour, rice husk, straw and other waste plant fiber into a new wood material, Molding, injection molding and other plastic processing technology to produce the plate or profile. WPC products to overcome the low strength of wood and variability of the use of limitations, but also to overcome the low modulus of organic materials and other shortcomings, than a single polymer material better mechanical properties, the product can be recycled, economic and Social benefits, so great market prospects. Mainly used in construction, automotive industry, logistics and packaging industries.
Wood-plastic materials with wood, plastic and metal materials such as the quality characteristics of the material, better than any one, with good processing performance, high strength, and longer life, water, corrosion, insect moth, and in the treatment of plants Fiber and plastic bonding properties, you can add some reagents, so that plastic foam, modification, polymerization and other changes, both to improve the toughness of composite materials, but also reduce the density. The biggest advantage of wood-plastic composite materials is the use of waste plant straw plant and waste plastic as raw materials, to achieve green, turning waste into the purpose of treasure.
