WPC door is a kind of low foaming and internal and external skin integral door which is made of fine wood powder and PVC resin by molding extrusion with various functional aids.
The main raw materials are PVC resin and high-quality wood powder. PVC resin adopts medical grade domestic brand products. The wood powder is provided by professional wood industry company to provide high-quality tree species wood powder. After grading screening, grinding, drying and coating treatment, the requirements of the finished products on the quality of raw materials are guaranteed. The wood plastic door formula system is equipped with a certain proportion of auxiliary materials, including stabilizer, foaming agent, modifier, etc., and all kinds of ingredients are mixed in strict proportion to effectively ensure the product quality of foaming plate.
The production equipment is imported from abroad from the mixing system to the extrusion system, ranking the international leading level and high automation. The mixing equipment has the characteristics of accurate dosage, uniform mixing and high efficiency, which fundamentally ensures the stability of the product. Because of the high demand of foam extrusion equipment in the production of wood plastic foam door, the twin screw extruder with high torque is adopted, and the screw and screw barrel are modified to adapt to the skin forming and uniform foaming on the inner and outer surface of the lignin, and avoid the carbonization of wood powder.
The following performance characteristics are used to distinguish the quality and the bad:
(1) Green and environmental protection
The raw materials used for the wooden plastic door of Longqiao are once formed under high temperature, high pressure and vacuum conditions, and the material does not contain formaldehyde. During the secondary processing, the heat transfer printing technology is adopted to avoid paint. There is no toxic and harmful gas and odor release during the production and use. It is a human friendly product which conforms to the environmental protection standards for decoration in modern rooms.
(2) Waterproof, moisture-proof, anti-corrosion, mildew proof, moth proof, deformation free
Wood plastic products have dual characteristics of wood and plastic. Therefore, the wooden plastic package door is used outside the indoor room, especially suitable for places with large temperature difference, humidity and poor ventilation, such as wet toilet, which needs to be antiseptic, mould proof and mothproof storage room.
(3) Reasonable structure and high strength
The special chamber structure design ensures the ideal internal structure of the wood plastic foam material, and the excellent formula design and reasonable production technology ensure the strength of the product.
(4) Installation structure, time saving and labor saving
The wooden plastic door adopts the German introduced quick installation structure, which is very convenient to install. The door sleeve line and the door cover are connected by bayonet, and no gun nail or adhesive is required to fix.
(5) Series products, many colors and strong matching
In view of different market demands, gallop design the whole door and welding door. The whole door has dozens of surface designs for selection, and the welding door can provide profile for the door and window assembly factory. Wood plastic material has the processing performance of solid wood, which can be planed, sawn, drilled, milled and glued, and also suitable for traditional woodworking processing technology.
The door cover size is available in 8-10 sizes according to the width of the wall.
The color of the door package provides black walnut, teak, American cherry, white oak, redwood and so on.
(6) Good insulation and sound insulation performance
The material used in wood plastic door package has uniform and fine bubble hole and special design chamber structure, which ensures that its thermal conductivity is lower than that of general plastic material and noise reduction performance is good. The heat transfer coefficient of the product is 1w/m2.k, and the insulation performance reaches the grade I of gb/t16729-1997; The sound insulation performance grade is 6, with good insulation and sound insulation performance.
(7) Good flame retardant performance
Wood plastic suit door will not be ignited by open fire, and will be extinguished automatically after it is alive. The test shows that the oxygen index of Longqiao wood plastic door is 48, and its fire resistance grade is B1. The performance of Longqiao wood plastic door will greatly improve the fire safety of home houses.
(8) Significant cost performance advantages
Industrial manufacturing, stable quality, cost economy, and product price have always competitive advantages
