The pu sandwich panel line combines thin, high-strength materials on a single-sided or double-sided outer layer of thicker and lighter materials to form a new type of building material with high strength, light weight, sturdiness and durability, and beautiful appearance. . Generally, the outer layer is made of 0.3-0.6 mm colored steel plates, and materials such as stainless steel plates, aluminum plates, and plastic plates can also be used. The inner core is made of thicker and lighter materials such as flame-retardant EPS expandable polystyrene, foamed polyurethane, or glass magnesium, glass wool and other refractory materials. The thickness is between 50-300 mm and can be selected at will. It has also become one of the more ideal new building materials in today's building materials industry and has been applied.
The sandwich polyurethane sandwich panel produced by the polyurethane sandwich panel production line is made of color steel plates and light-weight inner core materials. The single-sided or double-sided outer layer is made through the special polyurethane sandwich panel production line to form high strength, light weight and heat insulation. A new type of construction and decoration material with good thermal insulation effect. Because of its durability, beautiful appearance, convenient construction and low cost, it is widely used in industrial plants, large warehouses, large-span roofs, walls, simple houses, kiosks, cold storage, clean rooms, Air-conditioned rooms and other places. Color coated steel plate, galvanized steel plate, stainless steel, galvanized plate, PVC, etc. as the surface layer, with polystyrene, flame-retardant paper honeycomb, glass magnesium, rock wool, glass wool and other light, fire-resistant and flame-retardant The new building material with the material as the core layer has obvious advantages such as light weight, good sound insulation, good sound absorption and sealing performance, convenient construction, short cycle, low comprehensive cost, bending resistance, corrosion resistance, and beautiful appearance. When the cold storage board is produced, the foam is processed, the overlap is tighter, and the heat preservation effect is better. The surface material stainless steel has strong anti-corrosion ability and high toughness. The polyurethane sandwich panel of aluminum foil paper surface material is more affordable, beautiful, durable, and has good heat preservation, heat insulation and sound insulation effects.
