1. Polyurethane cold storage board uses lightweight polyurethane as the inner material of the cold storage board. The advantage of polyurethane is that the thermal insulation performance is very good. The outer part of the polyurethane cold storage board is made of SII, pvc color steel plate and Stainless Steel Plate assembly. The advantage of this is that Prevent the cold storage plate from spreading due to the large temperature difference between inside and outside, so that the cold storage can be more energy-saving and improve the working efficiency of the cold storage.
2, polyurethane cold storage board fire, flame retardant, high temperature. Polyurethane is a flame-retardant self-extinguishing material after adding flame retardant. Its softening point can reach above 250 degrees Celsius. It will only decompose at higher temperature: in addition, polyurethane will be in its foam when burned. The surface forms ash, which helps to isolate the underlying foam. Can effectively prevent the spread of fire. Moreover, polyurethane does not generate harmful gases at high temperatures.
3. Due to the excellent thermal insulation properties of the polyurethane sheet, the thickness of the outer protective structure of the building can be reduced and the indoor use area can be increased.
4, strong resistance to deformation, not easy to crack, stable and safe finish. The porosity of the polyurethane material is stable and basically closed-cell structure, which not only has excellent heat preservation performance, but also has resistance to freezing and thawing and sound absorption. The average life of the rigid foam polyurethane insulation structure can reach more than 30 years under normal use and maintenance conditions. Can be achieved under normal conditions of use during the life of the structure, in dry, wet or galvanic corrosion, and because the unit price of insect, fungus or algae raw materials is higher than the unit price of other traditional insulation materials, but the increased cost will be heated by And offset by a significant reduction in cooling costs.
