Wood plastic composite definition and characteristics

Time: 2011-12-14
Wood plastic composite is booming at home and abroad in recent years, a new class of composite materials, refers to the use of polyethylene, polypropylene and polyvinyl chloride, etc., instead of the usual resin adhesives, and more than 50% of wood flour, rice husk, straw and other waste plant fibers mixed into the new wood, and then by extrusion, molding, injection molding and other plastic processing technology to produce plates or profiles. Mainly used for building materials, furniture, logistics, packaging and other industries. Plastic and wood powder mixed in proportion by hot extrusion molding of the plate, called the wood-plastic composite sheet extrusion.
 Features: Wood plastic composite base for high-density polyethylene and wood fiber, determine its own with some of the characteristics of plastic and wood.
 1) Good processing performance
 Wood-plastic composite materials containing plastics and fibers, therefore, has a similar processing of wood with the performance, can be sawed, nailed, planed to use woodworking equipment to complete, and nail-holding power is superior to other synthetic materials. Mechanical properties superior to wood. Nail-holding strength of wood is generally three times, five times a particleboard.
 2) Good strength properties
 Wood-plastic composite materials containing plastic, which has good elasticity modulus. In addition, fiber and contains the full mix with the plastic, which has the hardwood considerable compression, bending and other physical and mechanical properties, and its durability is superior to normal wood. High surface hardness, the wood is generally 2 - 5 times.
 3) Wood plastic composite with a water-resistant, corrosion resistance, long service life
 Wood and wood materials and products compared to strong acid-resistant, water-resistant, corrosion-resistant, and not the growth of bacteria, can not easily be moth-eaten, not long fungi. Long life, up to 50 years.
