Three years is a natural plant fiber and wood-plastic (mainly high-density polyethylene) as the main raw material, antioxidants, UV stabilizers, lubricants, coloring agents necessary auxiliary materials at high temperature and pressure, Sichuan wood door manufacturers After professional WPC extrusion extrusion equipment, with performance characteristics of wood and plastic. A wood texture strong; 2, water preservation, affordable; 3, eliminating maintenance of Sichuan wood paint companies, use of cost savings; 4, resistance to UV rays, lasting color constant; 5,100% environmentally friendly wood in Sichuan, saving forest resources ; 6, walking barefoot, non-slip, easy to crack; 7, the temperature adaptability for between minus 40 degrees to 60 degrees above zero; 8, anti-impact Sichuan wood manufacturers, quality and durability. Long spring three wood industry where in addition, the implementation of industry standards as well as the packaging industry standard "Combined wood pallets," has been enacted, the forestry industry standard "WPC sheet extrusion" light industry standards. " Landscape with polyethylene plastic wood composite profiles. " In addition, Guangdong Province also enacted local standards "WPC technology" and "WPC inspection and test methods" and so on. The project has been developed, ranking, there are eight pending standards, including: GB commissioned by the project's "WPC product physical and mechanical properties test", "WPC decking and fence system performance levels," "WPC artificial weathering test methods", "WPC product physical and mechanical properties test", "WPC test"; by the Ministry in charge of "building decorative wood composite wall", "wood use "and" physical and mechanical properties of the base material evaluation methods WPC fiber material "; by the Ministry of Housing is responsible for" building application of technical regulations with the WPC board "; by the State Forestry Administration, responsible for the" wood baseboard. " "Difficult to see from the above, in the WPC industry technical standards setting process, multi-stakeholder, multi-management of a very serious problem." According to Liu Jia, currently the world wood industry standards are still in a a gradual process, but due to profit-driven, China's standards appeared herd situation, leading to the formulation of the standards and the presence of the management of multiple management, chaotic, cross-duplication, waste of resources, as well as drafting and formulating standards sloppy work, Pan interests of circumstances. Some drafted by low level of specialization, product index is much lower than the current requirements for the development of the industry in advanced enterprise product index and practical applications, seriously disturbed the market order, affect the healthy development of wood-plastic composites industry.
