Development Prospects of WPC

1) High-quality raw materials and scientific formula The main raw materials of the wood-plastic door are PVC resin and high-quality wood powder. The PVC resin is made of medical-grade domestic famous brand products. Drying, coating treatment, to ensure the finished product quality requirements of raw materials. The formula system of the wood-plastic door is equipped with a certain proportion of auxiliary materials, including stabilizers, foaming agents, modifiers, etc., and various components are mixed in strict proportions to effectively ensure the product quality of the foamed board.

2) Advanced production equipment The advanced production equipment is imported from abroad from the mixing system to the extrusion system, which is at the international leading level and has a high degree of automation. product stability. Due to the high requirements for foam extrusion equipment in the production of wood-plastic foam doors, a high-torque twin-screw extruder is used, and the screws, screw barrels and other components are modified to adapt to the lignin inner and outer surface crusting and Foam evenly to avoid the occurrence of wood powder charring and other phenomena.

3) The thermal transfer technology takes the lead in using the thermal transfer process to transfer various graphics on the extruded sheet, so that the product has a variety of high-grade wood grains and colors. According to the popular varieties in the market, we designed black walnut, ivory White, wax wood and other finishes are available for customers to choose from, and more than 50 interior door designs are provided to meet the needs of modern consumers.

4) The raw materials used for the green and environmentally friendly WPC door are one-time molding under high temperature, high pressure and vacuum conditions, the material does not contain formaldehyde, and the secondary processing adopts thermal transfer technology, free of paint, and there is no toxic or harmful during production and use. Gas and odor release, a human-friendly product that meets environmental standards for modern interiors.

5) Waterproof, moisture-proof, anti-corrosion, mildew-proof, moth-proof and non-deformable WPC products have the dual characteristics of wood and plastic, so the WPC set door is especially suitable for large temperature difference, humidity and poor ventilation except for indoor doors. places, such as damp bathrooms, anti-corrosion, mildew-proof, moth-proof storage rooms, etc.

6) Reasonable structure and high strength The special row cavity structure design ensures the ideal internal structure of the wood-plastic foam material, coupled with the excellent formula design and reasonable production process, to ensure the strength of the product.

7) Quick installation structure, saving time and effort in installation The wood plastic door adopts the quick installation structure imported from Germany, and the installation of the door cover is extremely convenient.

8) Good thermal insulation and sound insulation properties The materials used in the wood-plastic set door have uniform and fine cells and a specially designed row cavity structure, which ensures that its thermal conductivity is lower than that of ordinary plastic materials and its noise reduction performance is better. After testing, the heat transfer coefficient of this product is 1W/m2.k, and the thermal insulation performance reaches the first grade of GB/T16729-1997; the sound insulation performance grade is grade 6, with good thermal insulation and sound insulation performance 9) Good flame retardant performance WPC The door of the suit does not support combustion in case of an open flame, and it will automatically go out after being left alive. After testing, the oxygen index of the Longqiao WPC set door is 48, and its fire performance grade is B1. This performance of the Longqiao WPC set door will greatly improve the fire safety of the home.

Domestic wood basic raw materials have gone through two generations: the first generation is wood and wood, and the second generation is wood-based panels represented by plywood, fiberboard, particleboard, and wood pulp. In 2003, my country's wood-based panel production ranked first in the world. The third generation is wood-plastic material, which has been brilliant in the market. Wood-plastic material has both excellent properties of plastic and wood, and has an absolute advantage in door panel materials. At present, the domestic WPC market has huge potential. Although the annual output of WPC products in the world is only a few million tons, since 1998, Europe and the United States and other countries have increased at a rate of 65% every year. Among the 10 domestic wood-plastic manufacturers, 7 are foreign manufacturers, and all products are exported.

ChemChina's material testing department has strictly inspected the performance and environmental protection of the material to ensure that the rights and interests of consumers are not harmed.

Good mechanical properties, can be sawed, planed, nailed and other mechanical processing like wood, with hard, tough, durable, wear-resistant properties; after foaming, a large number of uniform and regular cells are formed, which can save the cost of products. Experiments show that, compared with unfoamed PVC/wood flour composites, the density can be reduced by 50% after extrusion foaming and can reach 0.6g/-1.0g/cm3. The uniform and regular cell structure after foaming can be passivated The elongation at break at the crack tip can be significantly improved. It is also an environmentally friendly material. The raw materials are cheap, abundant, and recyclable, which can reduce environmental pollution and protect forest resources.
