Wood plastic: refers to the use of polyethylene, polypropylene and polyvinyl chloride, instead of the usual resin adhesives, and more than 35%-70% of wood powder, rice husk, straw and other waste plant fiber mixed into new wood materials, and then extrusion, molding, injection molding and other plastic processing technology, raw materials or profiles. It is mainly used in building materials, furniture, logistics packaging and other industries. It is called extruded wood plastic composite board after mixing plastic and wood flour in a certain proportion and extruded by hot extrusion.
Wood plastic composites contain plastic, so they have good modulus of elasticity. In addition, because of the inner fiber and fully mixed with plastic, it has physical and mechanical properties such as compression and bending resistance to hardwood, and its durability is obviously better than that of ordinary wood. The surface hardness is high, usually 2 to 5 times that of wood.
Wood plastic performance:
1. products have the same processing performance as the logs. It can be stud, drillable, cut and bonded. It is fixed with nails or bolts. The surface is smooth and fine, without sand light and paint. The paint has good adhesion and can also be painted on the basis of personal preference.
2. products have better physical properties than logs. It is better than wood size stability. It will produce cracks, warp, wood free scars, twill, coloring agent, film covering or composite surface can be made into colorful products, so no time maintenance is needed.
3. can be a variety of specifications, sizes, shapes, thickness and other requirements, which also includes a variety of design, color and wood grain products, to give customers more choice.
4. products with fire, waterproof, corrosion, moisture resistance, not worm moth, fungi, acid and alkali, no poison, no pollution and other excellent performance, low maintenance costs.
5. the product has similar wood appearance, higher hardness and longer life than plastic. It can be thermoplastic, high strength and energy saving.
6. the product is firm, lightweight, thermal insulation, smooth and smooth, without formaldehyde and other harmful substances. It is harmless and pollution-free.
Wood plastic application:
Wood plastic door, floor, kicking line, whole cabinet, wardrobe, exterior wall hanging board, decorative hanging board, hanging board, outdoor floor, wood plastic guardrail, plastic steel Pavilion, garden guardrail, balcony guardrail, leisure bench, flower frame, air conditioning frame, shutter, and so on. The application of wood plastic materials is flexible and can be applied to any field of wood processing. It is the best environmental protection material to replace wood at present.
The advantages of wood plastic:
(1) waterproof and moistureproof. It solves the problem that wood products can be easily rotted and inflated after damp and multi water environment, and can be used in the environment where traditional wood products can not be applied.
(2) pest control and termite control, effectively eliminate insect disturbance and prolong service life. Wood plastic products
(3) colorful and varied colors. It has natural wood and wood texture, and can customize the colors according to its personality.
(4) the plasticity is strong, can realize the individual modelling very simply, fully manifests the individuality style.
(5) high environmental protection, pollution-free, pollution-free and recyclable. The product does not contain benzene, and the content of formaldehyde is 0.2. It is lower than the EO standard. It is the European standard of environmental protection. It can save the use of wood and be suitable for the national policy of sustainable development, and benefit the society.
(6) high fire resistance. It can effectively flame retardant, fire grade reaches B1 grade, extinguishes without fire, and does not produce any poisonous gas.
(7) machinability is good. It can be ordered, planed, sawed, drilled, and painted on the surface.
(8) simple installation, convenient construction, no complicated construction technology, save installation time and cost.
(9) no cracks, no expansion, no deformation, no need for maintenance and repair, easy to clean, save late maintenance and maintenance costs.
(10) the sound absorption effect is good, the energy conservation is good, causes the indoor energy conservation to be higher than 30%.
