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, Sichuan wood, 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. Chinese wood industry five "strange" phenomenon analyze large wood door line-for-wood substitution of consumers choose wooden doors, they often focus too much attention on the doors, while ignoring the Door and door line. Some profiteers and doors Door will use a different material, formal approach is made after the Door with wood frame wood door manufacturers in Sichuan, planing, planing straight, and then molding assembly is mounted on the wall, then covered with grass roots panels and trim panel. But currently on the market, some inferior Door does not do primary treatment, posted directly on the surface of a thin layer of decorative panels, wall plates and difficult to fully bond. In addition, Sichuan wood flooring, some traders known at the time of sale of goods is solid wood edges, but it tends to be replaced by wood. Ordinary WPC materials and wood edges do not look carefully, looks almost the same, but the price varies greatly, wood about a meter between 60 yuan to 80 yuan, Sichuan outdoor wood flooring, solid wood edges and materials have to 100 yuan. Solution: Door project acceptance package, you can set the side panel doors and hand percussion, drums empty if issued, it does not explain the underlying pad Blockboard grassroots sheet, should be removed redone. In the purchase, the merchant must ask Door, door line is what material, when they feel when you are knowledgeable, they will not dare to deceive you.
