Hollow plate whose name is also called hollow grid board, Wantong board, double-wall extruded panels, based on polypropylene (PP / PE) as the main raw material by extrusion molding, light weight (hollow structure), non-toxic, non-polluting , waterproof, shockproof, anti-aging, corrosion resistance, rich color and other characteristics, its superior environmental performance is increasingly being recognized, widely used in electronics, packaging, machinery, light industry, postal services, food hollow grid plate, medicine, pesticides, household appliances, advertising, decoration, stationery, magneto-optical technology, bio-engineering pharmaceutical and health industries. 1, good mechanical properties of the special structure of hollow plastic plate, it has good toughness, impact resistance, high compressive strength, cushioning shock, very rigid high, good bending properties such as excellent mechanical properties. 2, hollow plastic plate light and materials excellent mechanical properties, up to achieve the same effect, use less plastic hollow board supplies, low cost pc hollow sheet production line, light weight. 3, heat insulation, sound insulation due to the hollow structure of hollow plastic plate to heat transfer and sound effect was significantly lower than solid sheet, with good insulation, sound insulation effect. 4, anti-static, conductive, flame retardant use of modified, mixing, spraying and other ways to make the surface of hollow plastic plates with anti-static, conductive, or flame-retardant properties. 5, the chemical stability of hollow plastic plate can be waterproof, moisture, corrosion, pest control erosion, fumigation and cardboard, wood has obvious advantages. 6, the surface is smooth and beautiful, full color molding process due to the special hollow plastic plate by masterbatch can reach any color palette, and the surface is smooth and easy to print. 7, environmental effect is obvious hollow plastic plate with non-toxic, pollution, waste disposal is simple, does not pollute the environment, but also waste recycling, make other plastic products. Plastic Machinery Co., Ltd. Qingdao with three years of efforts, on the basis of a single-layer, three-story building template production line equipment design based on the successful design and development of a five-story building templates hollow plastic devices. The equipment consists of five out of the building template. Hollow core slab, the core and lower surfaces were coated with glass fiber network, and then were out of both sides of the surface layer is composed of two extruders, after molding, cooling, pulling, trimming, cutting, and so do a template required. Because of the production line equipment to make hollow boards joined upper and lower layers of glass fiber network, so a fundamental solution to the Normal template big weight, easy deformation of technical problems. Five hollow form with light weight, easy to eat nails, etc., but also reduces the labor intensity of construction workers. Vacuum forming table: middle setting system offers rapid heat exchange cooling system, and with the vacuum system to effectively cross pp hollow sheet production line, the order of distribution, this ensures calibrating precision. Vacuum system consists of two independent subsystems, each subsystem is equipped with a fixed number of three-loop vacuum lines, each fixed all through the bad association with vacuum-conditioning system and vacuum display system, so that the degree of vacuum plate surface uniformity and stable. Tractor: Tractor distribution first and second groups, the first group of traction for high-power, high reduction ratio, multi-roll style, its excellent performance at low speed, traction, can be synchronized evenly straight empty plate from stereotypes Taichung pull. The second group of the tractor to remove stress. Comes with a trimming device to ensure the quality of the sheet edge. Strain Relief: advanced large area preacher heating, so that the plate effectively eliminate stress, to further improve the flatness of the plate. Cutter: with a precise moment and Cutting and automatic lift unloading, special alloy steel sharp blade to ensure the quality of cutting of. pc hollow sheet production line _ with three presses (certified) _ hollow grid plate is provided by the same three-Plastic Machinery Co., Ltd. Qingdao. Plastic Machinery Co., Ltd. Qingdao with three (www.tongsansuji.com) is Qingdao, other leaders, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. In the same three presses leadership with the staff warmly welcome all inquiries to discuss, with three presses to create a better future.
