Environmentally friendly wood also named plastic wood and polywood. It is made of 100% PE plastic raw material and extruded into a wooden strip shape. It looks like the color and texture of the wooden strip, and has good moisture resistance, water resistance, acid and alkali resistance. Anti-oxidation, anti-insect and anti-fading properties. Gradually replacing solid wood is widely used in outdoor wall decoration, outdoor furniture, garden pavilions and other fields. As a new type of composite material, environmentally friendly wood is made of 100% HDPE (high density polyethylene) and added with a small amount of auxiliary materials such as antioxidants and flame retardants. Shaped wood strip profiles.
Wood-plastic is made of 30% polyethylene and 70% wood fiber. The wood fiber can be wood flour, gluten or wood fiber. It can not only reuse waste, but also conform to the national policy of “saving wood”. In addition, wood-plastic outdoor performance is better than solid wood in outdoor use, such as waterproof, moisture-proof, anti-corrosion, anti-mold, anti-insect, etc., so it is widely used outdoors.
However, after many years of using, WPC has found some problems. Wood-plastic generally has a high content of wood fiber and a small content of PE, so it is relatively hard and brittle. It is easy to crack when the screw is deep; the surface of the broken wood-plastic strip is rough, and it is not suitable for use in tables and chairs that are in contact with the human body; Because the wood powder contained in it contains certain adsorption to water, it is difficult to clean; although some wood powder is used in the production of wood plastic to avoid wood powder as garbage, wood plastic can not be recycled after aging.
