Wood-plastic: refers to the use of polyethylene, polypropylene and polyvinyl chloride, replace the usual resin adhesive, and more than 35%-70% of wood powder, rice husks, straw and other waste plant fibers mixed into new wood materials, and then through extrusion, molding, injection molding and other plastic processing technology, the production of the plate or profile.Mainly used in building materials, furniture, logistics packaging and other industries.Material of plastic and woodiness powder press the plank that hot extrusion forms after mixing certain proportion, say to squeeze woodiness to model compound plank.
Wood-plastic composite materials contain plastics, so it has a good elastic modulus.In addition, because contain fiber and classics and plastic are mixed adequately, have the physical and mechanical property such as resisting compression, resisting bending with hardwood equivalent, and its durable sex is better than common woodiness material apparently.Surface hardness is high, generally 2 to 5 times that of wood.
Wood plastic properties:
1. The product has the same processing performance as the log. It can be nailed, drilled, cut and bonded, and fixed with nails or bolts.
2. The product is more excellent physical performance than the log, better dimensional stability than the wood, noise will produce cracks, warping, no wood knot scar, twill, add colorant, laminating or composite surface layer can be made into a variety of colorful products, so there is no need for regular maintenance.
3. Can meet a variety of specifications, sizes, shapes, thickness and other requirements, which also includes providing a variety of designs, colors and wood grain finished products, to give customers more choices.
4. The product has fire prevention, water resistance, corrosion, moisture resistance, no moth, no fungus, acid and alkali resistance, no poison, no pollution and other excellent performance, low maintenance cost.
5. The product has a similar appearance to wood, higher hardness than plastic, longer life, thermoplastic molding, high strength, energy saving.
6. The product is firm in quality, light in weight, heat preservation, smooth and smooth in surface, free from formaldehyde and other harmful substances, non-toxic and pollution-free.
