Recently, there are more and more people building cold storage, and most people have chosen to use polyurethane cold storage plates for cold storage construction. What is the reason? Why do people choose polyurethane cold storage plates for construction? What are the advantages of polyurethane cold storage plates? The following is a detailed introduction.

The polyurethane cold storage board uses light polyurethane as the inner material of the cold storage board. The advantage of polyurethane is that the heat insulation performance is very good. The exterior of the polyurethane cold storage board is made of SII, pvc color steel plate and stainless steel plate components. The advantage of doing so is to prevent cold storage Because of the large temperature difference between the inside and outside of the board, the temperature spreads, which makes the cold storage more energy-saving and improves the working efficiency of the cold storage.

Polyurethane cold storage board is fireproof, flame retardant and high temperature resistant. Polyurethane is a flame-retardant self-extinguishing material after adding flame retardant. Its softening point can reach more than 250 degrees Celsius, and it will only decompose at higher temperatures: In addition, polyurethane will burn in its foam when burning Ash forms on the surface, and this layer of ash helps isolate the foam underneath. Can effectively prevent the spread of fire. Moreover, polyurethane does not produce harmful gases at high temperatures.

Because polyurethane sheet has excellent thermal insulation performance, under the same thermal insulation requirements, it can reduce the thickness of the building envelope, thereby increasing the indoor use area.

The choice of the polyurethane cold storage board is very important for the cold storage, because the cold storage is different from the ordinary storage, the temperature in the cold storage is generally relatively low, and the air temperature, humidity, and environmental requirements are relatively The temperature is high, so we must pay attention to the choice of polyurethane cold storage board with better temperature control when choosing polyurethane cold storage board. If the choice of polyurethane cold storage board is not good, resulting in the temperature in the cold storage is difficult to control, it is easy to cause storage in The products in the cold storage have deteriorated, or the refrigeration compressors in the cold storage have been working frequently, wasting more resources and increasing costs. Choose the correct plate to better maintain the cold storage.

Strong resistance to deformation, not easy to crack, stable and safe finish. The polyurethane material has a stable porosity structure and is basically a closed-cell structure, which not only has excellent thermal insulation performance, but also has good freeze-thaw resistance and sound absorption properties. The average life of the rigid foam polyurethane insulation structure can reach more than 30 years under the conditions of normal use and maintenance. It can achieve the unit price of dry, wet or galvanic corrosion under normal use conditions during the life of the structure, as well as the unit price of insect, fungus or algae foam material is higher than that of other traditional insulation materials, but the increased cost will be from heating And a substantial reduction in cooling costs.
