Wood plastic composite materials (Wood-PlasticComposites, WPC) is a new type of composite materials at home and abroad in recent years, the booming, refers to the use of polyethylene, polypropylene and polyvinyl chloride resin adhesive, instead of the usually more than 35%-70%, rice husk and wood powder, straw, waste plant fiber mixed into new wood materials, then by extrusion molding injection molding, plastic processing, production of plates or sections. Mainly used for building materials, furniture, logistics, packaging and other industries. The plastic and wood powder plate by hot extrusion mixed at a certain ratio, called wood plastic extrusion Composite plate.
Wood plastic composite material containing plastic, so it has better elastic modulus, good rigidity and toughness, able to nail, drilling, grinding, sawing, planing, paint, and not easy to deformation, anti cracking. In addition, because the embedded fibers and plastics are fully mixed, and thus has considerable compressive bending hardwood. The physical and mechanical properties, and its durability is better than ordinary wood materials. The surface hardness is high, usually of wood 2 - 5 times, is the furniture industry, interior decoration industry, packaging industry, travel industry and future interior wooden houses construction industry preferred green environmental protection board, will set off a new revolution in the plate market.
The density fiberboard is also known as the board, wood fiber or other plant fiber as raw material, applying urea formaldehyde resin or other suitable adhesive made of man-made plate. According to the amount of different, divided into high density board, MDF, MDF. Low density board as soft impact resistance, easy processing. Abroad is a good material for making furniture, but because of the national standard of high density board several times lower than international standards, so use quality MDF still needs to be improved.
