Wood-plastic, that is, wood-plastic composite material, is a new type of composite material that is flourishing in recent years at home and abroad. It refers to the use of polyethylene, polypropylene and polyvinyl chloride, instead of the usual resin adhesive, with more than 35% -70% Wood, rice husk, straw and other waste plant fiber mixed into a new wood material, and then by extrusion, molding, injection molding and other plastic processing technology, to produce the plate or profile. Mainly used in building materials, furniture, logistics and packaging industries The plastic and wood flour according to a certain percentage of mixed by hot extrusion sheet, called extruded wood-plastic composite sheet. Now take a look at the advantages and applications of wood-plastic composite material.
Good processing performance
Wood-plastic composites contain plastic and fiber, therefore, have similar processing properties as wood, sawing, stapling, planing, woodworking tools can be completed, and holding nail strength is superior to other synthetic materials. Better than wood, nail holding force is generally 3 times the wood, 5 times the particleboard.
Good strength performance
Wood-plastic composites contain plastic and thus have a good modulus of elasticity. In addition, due to the inclusion of fiber and fully mixed with plastic, it has comparable to hardwood compressive, bending and other physical and mechanical properties, and its durability Significantly better than ordinary wood materials, high surface hardness, usually 2-5 times that of wood.
With water, corrosion resistance, long service life
Compared with wood, wood-plastic materials and their products are resistant to strong acid and alkali, water and corrosion-resistant, and do not breed bacteria, insects are easy to moth-eaten, not long fungi, long service life, up to 50 years.
Excellent adjustable performance
Through additives, plastics can be polymerized, foaming, curing, modification and other changes, thereby changing the density of wood-plastic materials, strength and other characteristics, but also can meet the anti-aging, anti-static, flame retardant and other special requirements with UV light stability Sex, good coloring.
Recycling
Its biggest advantage is turning waste into treasure, and can be 100% recycled and can be decomposed, will not cause 'white pollution', is a real green products.
Raw materials from a wide range
Plastic raw materials for the production of wood-plastic composites are mainly high-density polyethylene or polypropylene. Wood fibers may be wood flour, chaff or wood fibers. Small amounts of additives and other processing aids are also required.
Customized
Can be customized according to the needs of any shape and size.
Product range of applications
With excellent characteristics of plastic wood / wood plastic materials: widely used in outdoor landscape engineering, municipal parks, residential property gardens, outdoor wood works, river guardrails, building walls, building shade, huts, villas, docks and other docks.
