What is a wood-plastic
Wood plastic is a new class of composite materials at home and abroad have mushroomed in recent years.
What is a wood-plastic: refers to the use of polyethylene, polypropylene and polyvinyl chloride, etc., instead of the usual resin adhesive mixed with more than 35% -70% wood flour, rice husk, straw and other waste plant fiber into new wood materials , and then by extrusion, molding, injection molding, plastic processing, to produce plates or profiles. Mainly used for building materials, furniture, logistics, packaging and other industries. By heat of plastic and wood powder mixed by a certain percentage of extruded sheet, known as extruded wood-plastic composite sheet.
Wood-plastic composite materials containing plastic, and therefore has good elastic modulus. In addition, because the mixing of containing fibers with plastic, and thus has considerable compressive strength and the hardwood, resistance to bending and other physical and mechanical properties and its durability is superior to ordinary wood materials. High surface hardness, is generally 2-5 times that of wood.
Shanghai Seven Trust Industry Co.,Ltd. , carefully crafted of wood-plastic material – seven true ecological wood. Of raw materials. Product performance for the upgrading and improvement of the rational, the performance is substantially higher than the original design and production standards.
Wood plastic composite properties
1. wood-plastic products has the same processing performance and logs, wood can be nailed, drilling, cutting, bonding, fixed with nails or bolts to connect the surface is smooth and delicate, without sanding and paint, good paint adhesion. can also be painted according to personal preference.
2. Wood-plastic products have better physical properties than wood, better stability than the timber size, noisy cracks, warping, wood knots, twill, by adding coloring agents, film or composite surface made of colorful a variety of products, so do not need regular maintenance.
3. Wood-plastic products needs of a variety of specifications, size, shape, thickness, it has a variety of design, color and wood grain finished, giving customers more choices.
4. Wood-plastic products with fire, water, engage in corrosion resistant to moisture, moth-eaten, not long fungi, acid and alkali, no poison, no pollution, and excellent performance, low maintenance costs.
5. Wood-plastic products like wood appearance than plastic, high hardness, long life, thermoforming, high strength, energy conservation.
6. wood-plastic products are hard, the amount of light, heat, smooth surface, free of formaldehyde and other harmful substances, no poison, no pollution.
Shanghai seven true production of green wood is a high performance wood-plastic materials.
wood-plastic interior doors, flooring, skirting board, the whole cabinet, wardrobe, siding, decorative hanging board, hanging on the board, outdoor flooring, wood plastic fence, steel pavilion, garden fence, balcony rails, leisure benches, planter boxes, air conditioning, frame, shutters, and so on and so on. Wood-plastic material is flexible and can be applied to any field of wood processing, the best environmentally friendly materials replaced wood.
Shanghai Qizhen really the introduction of advanced production technology, according to the needs of different clients, customized different mold to produce all kinds of wood-plastic products for different consumer needs. Production process according to the ingredients, temperature, foam rate adjustment to control the density, hardness, color, etc. of the product.Produce different advantages for different use of wood-plastic products.
