People have an affinity for wood, and home decoration is inseparable from wood. However, the wood itself also has its own shortcomings, such as shrinkage and cracking easily, deformation when exposed to water, moldy when exposed to moisture, and easy to burn when exposed to fire. Among them, formaldehyde can also cause indoor pollution. Is there a new type of material that “only has the advantages of wood, no disadvantages of wood”, “not wood, better than wood”? Now there is. This is to use wood flour, rice husk, straw and other waste plant fibers to mix PE particles through high temperature and high pressure synthesis
The key to cracking the high-value utilization of wood-plastic composites
In foreign countries, after more than ten years of research, development and industrial application, wood-plastic composite materials have formed a new industry. Wood-plastic composite materials use wood powder, agricultural straw powder and other plant fibers and plastics as the main raw materials, and are processed by advanced technology, and the products can be recycled and reused. From the sensory point of view, the wood-plastic material has a good wood feeling, moisture resistance, good coloring, heat insulation, insulation and anti-corrosion, and its mechanical properties are 10 times higher than that of pure wood materials, making it an ideal substitute for natural wood. In North America alone, the annual output is more than 400,000 tons, and the output value is 1.2 billion US dollars. European industrialized countries, Japan, Australia, etc. are also developing wood-plastic and natural fiber composite products. Mainly using waste plastics, branch powder, agricultural straw powder and other plant fibers as raw materials, the products are widely used in packaging, gardening, transportation, construction, vehicle and ship interiors and other fields.
Because WPC is a green and environmentally friendly material, it just echoes our country’s protection of the environmental protection and ecological environment, so it is a very promising development trend for WPC.
