The status past and future development direction of WPC wood plastic industryThe status past and future development direction of WPC wood plastic industry
WPC products (referred to as WPC in English, also known as WPC) products have been widely used after technological improvement since they were introduced into China in the late 1990s. The environmental protection, stability and adaptability of wood-plastic products have become an important boost for the development of wood-plastic products and industries; the next step in the development of wood-plastic industry needs to focus on enhancing industry concentration and expanding the mid-to-high-end consumer market.
In the late 1990s, China introduced and applied wood-plastic production technology and improved it. Wood-plastic products began to be widely used in important places such as the Beijing Olympic Games, Shanghai World Expo, and Guangzhou Asian Games. In recent years, under the tremendous pressure of environmental resources, wood-plastic products have the characteristics of broad spectrum of raw materials, preparation of plasticization, product ecologicalization, application economics, and low-carbon recycling, which have laid the foundation for their industrialization to leapfrog and upgrade.
"Wood" used in wood-plastic products is the remaining biomass fiber resources, mainly forest product processing wastes and crop straws, such as sawdust, wood shavings, bamboo shavings, wheat straw, rice straw, rice husk, corn straw, etc., after screening , Crushing and other processes into biomass fiber raw materials. "Plastics" in wood-plastic products are currently mainly made of thermoplastics, including polyethylene (PE), polypropylene (PP) and polyvinyl chloride (PVC).
Compared with wood products, wood-plastic products have the same feelings as wood products. Their appearance and texture are similar to wood, and they have the same processing performance and installation performance as wood, which can meet personalized design requirements, while largely avoiding natural wood. The defects, such as cracks, warpage, scarring, and obvious color difference, are sustainable comprehensive utilization materials encouraged by the state.
More importantly, wood-plastic products do not contain toxic substances such as formaldehyde, toluene, lead, chromium, etc., and the environmental protection safety is very reliable; its excellent moisture resistance, water resistance, moth resistance and other functions can greatly improve the environmental adaptability of household products Sex. At the same time, the ease of installation of wood-plastic products greatly reduces the workload of manufacturing and installation of furniture and integrated houses, very in line with the requirements of prefabricated buildings, and has a lower cost of use.
Xin Zhiwei, deputy director of the Ministry of Ecology and Environment, said that the use of a large number of artificial composite plates and adhesives has made formaldehyde, toluene and other volatile organic compounds a serious threat to human health. During the production of these products, a large amount of volatile organic compounds will also be released. Wood plastic products as a new bio-fiber composite material will effectively solve this problem.
At present, the market prospect of wood-plastic composite materials is promising, which is in line with the national energy conservation, environmental protection, green and sustainable development directions. However, there is still a lack of large-scale backbone enterprises in the industry, and low-end and middle-end products occupy the main market. Most production enterprises are currently staying in the material The production and sales are also limited to outdoor walkways, guardrails, pavilions, corridors and other garden landscape industries. The industry's transformation and upgrading are slow.
Qin Tefu, a researcher at the Institute of Wood Industry of the Chinese Academy of Forestry, also said that the next step in the wood-plastic industry should focus on the technological level of the wood-plastic products production link to increase the market share of high-end wood-plastic products so that more consumers can enjoy To the changes that wood-plastic products bring to life.
