Development Trends of Plastic Wood Industry
Wood-plastic composite materials have become a type of material with great development prospects due to their many advantages such as material saving, environmental protection, and recyclability. my country's vigorous development of wood-plastic composite materials is in line with the needs of the development of the national economic situation, and in line with the country's industrial policies and Energy conservation, environmental protection, and low-carbon economy requirements.
From the initial development of pallets, packaging boxes, automobile interior parts and other products, plastic wood composite materials have been developed and applied in outdoor decking, fences, tables and chairs, etc.At present, it has begun to penetrate into the broader field of building structures, striving to meet the mechanical performance requirements and external decorative effects of house structural parts and other products, including door and window products, decorative panels, furniture panels and house basic parts, etc.Correspondingly, higher requirements have been put forward for material performance, such as: outdoor products must be anti-aging, anti-fading, and have a long service life;Indoor doors, windows and decorative materials must have good flame retardant properties; basic building parts and load-bearing products must have high mechanical properties and need to be reinforced and modified to resist creep.
With the improvement of energy-saving requirements, the construction industry has also put forward higher requirements for the energy-saving effect of plastic-wood composite products.Therefore, wood-plastic composite materials are developing in the direction of functionalization and high added value to adapt to a wide range of applications.Such as flame-retardant, enhanced, anti-aging, anti-creep, thermal insulation and energy storage and temperature-regulating types, etc. will become the direction pursued by the industry.
Due to the guidance of national circular economy and industrial development policies, new biomass wood plastic materials with the two major advantages of resource conservation and environmental protection are bound to have greater development in the next few years.According to the current industrial development trend and market capacity forecast, if China's plastic-wood composite material industry can make breakthroughs in technology and quality,By 2020, the total output of plastic-wood composite materials is expected to exceed 4.6 million tons, with an output value reaching about 40 billion yuan, with an average annual growth rate of 25%, and the output value of the entire industry chain will exceed 50 billion yuan.
As an ideal environmentally friendly material, wood-plastic composite materials are low-cost and can be reused and recycled. They are gradually replacing some products that pollute the environment.In the future, while ensuring the growth of production capacity and output, we must open up new markets and develop new products;Innovate in molding technologies such as co-extrusion, injection molding, pressing and hot pressing to achieve product diversification and serialization; further promote the integration of production, learning and research, and establish a scientific and technological innovation mechanism. The development prospects of the plastic wood industry are promising not only in China, but also around the world. This is not only due to the excellent characteristics of the product itself, but more importantly, its significance in resource recycling and its important contribution to environmental protection.
