Product Description

0.Polyurethane sandwich panel is a polyurethane thermal insulation sandwich panel for construction, also known as anti-leakage sandwich roof panel, polyurethane rigid foam insulation panel, polyurethane composite panel, PU panel, etc. It is a highly efficient and energy-saving building envelope material with a wide range of uses and great potential, and it is also a new type of energy-saving board advocated and promoted by the Ministry of Construction.

Product Description

A:Lightweight, novel, and beautiful in shape.The heavy halo is generally 10 kg/m2-14 kg/m2, which is equivalent to 1/30 of the light wall. The surface color is absolutely, without surface decoration.
B:Strength, stiffness, stability, washout resistance, good shock resistance, corrosion resistance and atmospheric resistance. It can be used to maintain the structure and load-bearing structure. Generally, the house does not need beams and columns.
C:Excellent thermal insulation, heat insulation and sound insulation performance. In terms of anti-condensation performance, the 35 mm thick air-cooled panel is equivalent to 1130 mm red wall.
D:The degree of prefabrication and assembly is high, and the construction is less affected by harsh weather. Therefore, compared with the traditional construction method, the construction period can be shortened by more than 40%.
E:Fire performance: Class B combustion performance, the highest operating temperature is 180°C (250°C for instant elbow), carbon formation under the direct action of the flame, no dripping, no curling, no melting phenomenon, the surface forms a layer after the flame burns "Graphite Foam" layer, which effectively protects the foam structure within the layer.






A. Thermal insulation performance: The thermal insulation performance of the polyurethane sandwich panel is better among the three. Under the premise of the same energy saving index, the thickness of the thermal insulation board can be reduced and the quality stability of the thermal insulation system can be improved.
B. Thermal stability: The thermal stability of rigid foam polyurethane can be as high as 120 °C, while the styrene board is only 70 °C. In this way, above a certain temperature, it is easy to cause secondary foaming of the benzene board, resulting in cracking of the board seam.
C. Combustion principle:Rigid foam polyurethane is a thermosetting material, which forms a carbonized layer after being heated and burned, which blocks the further penetration of heat and oxygen, hinders the further combustion of the foam, and is not easy to cause fire spread accidents. Polystyrene foam is a thermoplastic material, which shrinks and melts after being heated, and then drips and burns. It cannot produce a carbonization barrier layer, and it is very easy to cause flame spread and flashover accidents. However, flame retardants are often added to polystyrene foams to achieve the required flame retardant grade.
D. The scope of application is different:Polystyrene foam can only be molded and extruded in the factory state, while rigid polyurethane foam can be sprayed, poured and factory foamed, so the application methods and application fields are more diverse and convenient than polystyrene foam.

 

g envelope system software. Under the premise of considering the requirements of building heat insulation, sound insulation, fire safety and other regulations, it has achieved high quality, high efficiency, reliability and safety. overall goal.

Polyurethane sandwich panels are widely used in large industrial plants, cold storages, garages, mobile houses, exhibition halls, gymnasiums, shopping centers, airports, power plants, villas, hospitals, strata and high-rise office buildings, etc. For roofs and walls of industrial and civil buildings.
