The Environment Development Center of the Ministry of Ecology and Environment announced on the 12th in Beijing that China's environmental labelling wood-plastic products entered the government's green procurement list and issued certificates to four Chinese environmental labeling wood-plastic products certification companies.
The Environment Development Center of the Ministry of Ecology and Environment, the Environment Certification Center of the Ministry of Ecology and Environment, the China Wood Building Materials Industry Professional Committee of the China Green Building Materials Industry Development Association, and the Institute of Wood Industry of the Chinese Academy of Forestry and other leaders attended the meeting. Experts introduced the environment Signs of the characteristics of wood-plastic products, as well as corporate product certification and testing.
According to reports, the four companies that have obtained the certification of China's environmental labelling wood-plastic products have undergone rigorous testing and certification process screening. Their production processes and products comply with the “Environmental Labeling Products Technical Requirements—Wood-plastic Products” promulgated by the Ministry of Ecology and Environment ( HJ2540) standard requirements.
According to relevant persons from the Environmental Development Center of the Ministry of Ecology and Environment, the wood-plastic products produced by the four certified companies will be able to enter the government procurement list in the near future. Consumers will soon be able to enjoy the changes in life brought about by the wood-plastic products and thus be able to fundamentally It is also far from indoor pollution caused by organic volatiles such as formaldehyde. This is also part of the environmental certification center of the Ministry of Ecology and Environment to declare war on pollution and actively promote green production and consumption.
According to experts, the 'wood' used in wood-plastic products is actually the remaining biomass resources, mainly forest processing waste (sawdust, shavings, sawdust, bamboo shavings, bamboo velvet, etc.) and herbaceous materials (such as wheat straw, rice straw, cotton Rods, hemp sticks, clam shells, peanuts and chestnut shells, and sugar cane bagasse, etc. are processed into wood raw materials through screening, grinding, grinding, etc.; plastics in wood and plastic products are currently mainly made of thermoplastic plastics, including polyethylene ( PE), Polypropylene (PP) and Polyvinyl chloride (PVC), etc. In the actual production, new materials can be used, recycled materials and mixtures of the two can be used. Currently, polyethylene, polypropylene-based wood plastic products are used Outdoor building products, polyvinyl chloride wood plastic products are mainly used for interior decoration.
It is understood that wood-plastic products have three major advantages over wood products: First, they have a wide range of raw materials, and they are sustainable and comprehensively used materials encouraged by the state. Second, the appearance of products and wood products have the same feeling. The appearance and texture resemble wood, and they have The same processing performance as wood, construction performance, and can meet the individual design requirements; Third, the product to a large extent to avoid the defects of natural wood, such as cracking, warping, twisting, obvious color difference. Therefore, wood plastic composite materials Development is better than natural wood products.
