As people’s voices for protecting the environment and forest resources are rising, waste wood and plastics with low recycling costs have become a common concern in the industry, thus promoting the development of the wood-plastic composite industry.
Wood-plastic composite materials are a new type of composite materials that have flourished at home and abroad in recent years. They refer to the use of polyethylene, polypropylene and polyvinyl chloride to replace the usual resin adhesives, and more than 50% of wood flour, rice husks, straws, etc. The waste plant fiber is mixed into a new wooden material, and then the plate or profile produced by plastic processing such as extrusion, molding, injection molding, etc., is mainly used in building materials, furniture, logistics and packaging industries.
Wood-plastic composite materials are a new type of pre-treated wood fiber or wood powder compounded with thermoplastic resin and other materials, and are one of the main directions for the development of modern materials industry. It has good acid and alkali resistance, chemical resistance and salt resistance; it can be used at low temperature; it is resistant to ultraviolet light; it does not rot, cracks or warps, etc. It has good mechanical properties, low price, convenient processing and recyclability; Such as the release of harmful gases and other advantages. One of its main uses is to replace solid wood applications in various fields.
Industry experts believe that the various advantages of wood-plastic composite materials not only meet the requirements of the construction industry, furniture industry, logistics industry, etc., but also solve the problem of recycling of waste resources in the plastics and timber industries. Nowadays, China’s wood-plastic composite material manufacturing technology is mature day by day, but due to the small number of enterprises that can form scale in the industry, especially the lack of large-scale backbone enterprises, the development of industrial clusters still lacks a foothold in the soil, so overall, its industry Development has a long way to go.
Whether it is biomass wood-based panels or reorganized bamboo products, or wood-plastic composite products, these emerging forestry industries are rapidly entering industrialization and scale under the current macroeconomic situation of comprehensively promoting energy conservation and emission reduction and developing a low-carbon economy. The development track has a very broad development prospect.
