Advantages of polyurethane in cold storage insulation

The polyurethane cold storage plate uses light polyurethane as the inner material of the cold storage plate. The advantage of polyurethane is that it has very good heat insulation performance. The outside of the polyurethane cold storage plate is made of SII, PVC color steel plate and stainless steel plate components. The advantage of this is to prevent the temperature spread of the cold storage plate due to the large temperature difference between the inside and outside, so that the cold storage can save more energy and improve the working efficiency of the cold storage.

The advantages of polyurethane cold storage plate are as follows:

1. The polyurethane cold storage plate uses light polyurethane as the inner material of the cold storage plate. The advantage of polyurethane is that it has very good heat insulation performance. The outside of the polyurethane cold storage plate is made of SII, PVC color steel plate and stainless steel plate components. The advantage of this is to prevent the temperature spread of the cold storage plate due to the large temperature difference between the inside and outside, so that the cold storage can save more energy and improve the working efficiency of the cold storage.

2. Polyurethane cold storage plate is fireproof, flame retardant and high temperature resistant. After adding flame retardant, polyurethane is a flame retardant self extinguishing material. Its softening point can reach more than 250 ℃, and it will decompose only at higher temperatures. In addition, polyurethane will form ash on its foam surface when burning, which helps to isolate the foam below. It can effectively prevent fire spreading. Moreover, polyurethane does not produce harmful gases at high temperatures.

3. Due to the excellent heat insulation performance of polyurethane sheet, the thickness of building exterior enclosure can be reduced under the same heat insulation requirements, thus increasing the indoor use area.

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