The three important factors of cold room panel, the density of cold storage panel, the thickness of two side steel panels, and the bearing capacity. If the density of the thermal insulation board in the cold storage is large, the amount of polyurethane should be increased in the foaming of the board, and the thermal conductivity of the polyurethane board should be increased, so that the thermal insulation performance of the cold storage board will be reduced and the cost of the board will be increased. If the density of the foaming is too low, the load-bearing property of the cold storage board will be reduced. The foaming density of the general polyurethane thermal insulation board in the cold storage is 35-43kg as the standard after the test of the relevant national departments. In order to reduce the cost, some manufacturers have reduced the thickness of the color steel, which will directly affect the service life of the cold storage. When selecting the cold storage panel, it is necessary to determine the thickness of the color steel.
The selection of polyurethane cold storage panel is very important for the cold storage because the cold storage is different from the ordinary warehouse, the temperature in the cold storage is generally low, and the air temperature, humidity, and environmental requirements are relatively high, so we should pay attention to the selection of polyurethane cold storage board when we choose polyurethane cold storage board If the polyurethane cold room panel is not well selected, which makes the temperature in the cold storage difficult to control, it will easily lead to the deterioration of products stored in the cold storage, or make the refrigeration compressor in the cold storage work frequently, waste more resources, and increase the cost. Choose the right panel to get better maintain cold storage.
