Wood - plastic foam composite materials
Posted by Liu Yi over 6 months ago
Wood-plastic composites due to high density, high cost, brittleness, toughness, so in some industrial areas as a wood substitute applications are limited.In recent years, by adding foam in wood-plastic composites, the wood-plastic composite material in the formation of micro-holes, passivation crack tip, to prevent crack growth, can effectively control the lack of wood-plastic composite materials, making wood foam Materials in the automotive interior, aerospace and decorations have been applied.
Wood-plastic foam composite molding methods are molding, extrusion and injection molding, is a new field of study.Wood-plastic composites also need to protect wood-plastic composite materials as outdoor applications Wood substitutes the most fundamental advantage is its low maintenance and weather resistance. However, it must be noted that low maintenance is not maintenance-free. To protect the appearance of wpc need to add weathering pigments and uv stabilizer to reduce the fade. Some manufacturers also use a coextrusion method in the wood-plastic composite material coated with a layer of plastic to the wood and the environment to isolate, reduce the wood moisture and strain, and only in the surface layer using high-level additives.
Wood-plastic composite materials can be used waste plastics and waste wood as raw materials, which itself can be recycled, so in resources and environmental protection has a very good social effects, has been widely used in construction, transportation, automotive and other industries. The global processing industry for wood-plastic composite materials attention is rising, in Western countries have shown a rapid growth momentum. "There is a growing interest in the use of eco-friendly materials around the world, and industry needs to respond positively to this market need, respond to the challenges and urgently need reliable, profitable and cost-effective technologies to emerge. Wpc as an economic, ecological alternative to the outstanding application will cause increasingly widespread concern.
