do you know what is WPC door?
The wood-plastic door is made by mixing ultrafine wood particles with high-molecular resin through a molding process. It combines the excellent characteristics of wood and plastic, and the products produced achieve the effect of real wood imitation. Because the raw materials used and the production process are not glued, no harmful substances such as formaldehyde, benzene, ammonia, trichloroethylene and the like are produced, and it is a new green and environmentally friendly material that replaces traditional wood.

【Material composition of wood-plastic door】
The main raw materials of wood-plastic doors are PVC resin and high-quality wood powder. PVC resin uses medical-grade domestic famous brand products. Wood powder is provided by professional wood companies with high-quality tree wood powder materials. After grading and screening, grinding, drying and coating treatment, guarantee The quality requirements of raw materials for finished products. The wood-plastic door formula system is equipped with a certain proportion of auxiliary materials, stabilizers, foaming agents, modifiers, etc. are added, and various ingredients are mixed according to a strict ratio to effectively ensure the product quality of the foamed sheet.
【Features of production equipment】
The advanced production equipment is all imported from abroad from the mixing system to the extrusion system. It is at the international leading level and has a high degree of automation. The mixing equipment has the characteristics of precise dosage, uniform mixing and high efficiency, which fundamentally guarantees the stability of the product. Sex. Because the production of wood-plastic foam doors requires higher requirements for foaming extrusion equipment, a high-torque twin-screw extruder is used, and the screw, screw barrel and other components are modified to adapt to the skinning of the inner and outer surfaces of wood-plastic Foam evenly to avoid the phenomenon of wood powder charring.
【Surface treatment】
Thermal transfer technology is the leading use of thermal transfer technology to transfer various graphics on the extruded plate, so that the product has a variety of high-grade tree wood grain and color, according to the market popular varieties, we designed black walnut, ivory white, A variety of finishes such as wax oak are available for customers to choose from, and more than fifty interior door designs are provided to meet the needs of modern consumers' personalities.
Pros and cons

The wood-plastic door adopts the quick-assembly structure introduced from Germany. The door cover is very convenient to install. The door cover line is connected to the door cover with a bayonet. Effortless.
Disadvantages
1. Wood-plastic doors, the main material is wood-plastic materials, so wood-plastic doors have the same disadvantages as wood-plastic doors;
2. Wood-plastic doors are emerging environmental protection products, so a very standardized quality standard system has not yet been formed in the market.
3. There is no natural wood texture, so the wood-plastic door with thermal transfer technology or film absorption technology for surface treatment has no natural feeling.
4. Compared with wood, it is not resistant to high temperature and softens when exposed to high temperature.

research report
There are two generations of domestic wooden basic raw materials: the first generation is wood and wood, and the second generation is plywood, fiberboard, particle board, and wood-based pulp. In 2003, China's wood-based panel production has ranked first in the world. The third generation is a wood-plastic material, which has already shined in the market today. The wood-plastic material has the excellent performance of both plastic and wood, and has an absolute advantage in the door panel material. At present, the domestic wood-plastic market has great potential. Although the annual output of wood-plastic products in the world is only a few million tons, since 1998, countries such as Europe and the United States have increased by 65% every year.
China's chemical material testing department has undergone strict inspections on the performance and environmental protection of the material to ensure that the rights and interests of consumers are not harmed. It has good mechanical properties, such as sawing, planing, nailing and other mechanical processing like wood. It has the properties of hardness, toughness, durability, and wear resistance. After foaming, a large number of uniform and regular cells are formed, which can save costs. Experiments show that compared with unfoamed PVC / wood powder composites, the density after extrusion foaming can be reduced by 50%, up to 0.6g / -1.0g / cm3. The uniform and regular cell structure after foaming can be passivated The elongation at break of the crack tip can be significantly increased. It is also an environmentally friendly material, with cheap and abundant raw materials, recyclable, which can reduce environmental pollution and protect forest resources.
The wood-plastic material project entered the "High-tech Development Report 2002" of the Chinese Academy of Sciences; in the same year, it was included in the "863" project and "948" plan of the Ministry of Science and Technology, and a wood-plastic research group was established for this purpose. The five themes in the field are related and each has its place in cutting-edge technology and basic research. The wood-plastic composite material embodies the life characteristics of circular products that are derived from nature, are superior to nature, and are used in nature and attributed to nature.
In terms of operation, wood plastic can be processed with solid wood like logs, which can be nailed, drilled, planed, glued, and painted. The surface is smooth and delicate, without sanding and paint. At the same time, the adhesion of wood-plastic paint is good, and consumers can paint according to their personal preferences. As a new type of wood alternative material, wood plastic can be widely used in the field of architectural decoration and outdoor building materials, such as corner lines, chipboard slats, door and window lines, wood plastic floors, flower garden fences, skirting boards, ceiling lines, blinds, stair handrail , Decorative wall panels, outdoor pavilions, etc., most of the indoor and outdoor decorative building materials can be made of wood plastic. It is particularly worth noting that wood-plastic has a waterproof and fireproof function, which can be used in the decoration of kitchens, toilets, etc., which is beyond the reach of logs. Wood-plastic products have attracted extensive international attention and are hailed as new green and environmentally friendly materials, which will have broad development prospects.
A report analyzes that in 2005 North American plastic-wood composite outdoor cladding and fences accounted for 15% of the residential outdoor cladding and fence market. It is expected that the plastic-wood composite market will continue to grow strongly by 2010, and the cladding and fence market prospects are particularly promising. But demand growth is not limited to these two applications, and other products have also increased accordingly. According to the data provided by the report, the turnover of North American plastic wood outdoor decking and other construction products reached US $ 495 million in 2005, and is expected to increase to US $ 1.045 billion in 2008. From a global perspective, according to the research report of the US-based Principia Partners consulting company, it is expected that the world plastic wood composite material market will exceed US $ 1.4 billion in 2007. It will still maintain a good growth momentum by 2010, and the largest application is still to extrude building products. However, more types of plastic-wood building products are expected to appear, and the automotive and transportation industries are also markets where plastic-wood composite materials cannot be ignored.
