The cold storage panel has a fixed length, width and thickness. High and medium temperature cold storage generally use 10 cm thick panels, and low temperature storage and freezing storage generally use 12 cm or 15 cm thick panels; so if it is not a predetermined library panel, it is recommended when purchasing Pay attention to the density of the storage board and the thickness of the steel plate. The thickness of the steel plate of a regular manufacturer is generally above 0.4MM. The foaming density of the cold storage storage board is 38KG~40KG/m3 per cubic meter according to the national standard.
Basic introduction
The three important factors of the cold storage panel are the density of the cold storage panel, the thickness of the two-side steel plate, and the load-bearing capacity. The density of the cold storage insulation board is high, so the foaming of the board is to increase the amount of polyurethane, and at the same time increase the thermal conductivity of the polyurethane board, so that the insulation performance of the cold storage board will decrease and the cost of the board will increase. If the foaming density is too low, it will cause The load-bearing capacity of the cold storage board is reduced. After testing by the relevant national departments, the foaming density of the general polyurethane cold storage insulation board is 35-43KG as the standard. Some manufacturers have reduced the thickness of the color steel in order to reduce the cost. The reduction of the thickness of the color steel will directly affect the service life of the cold storage. When selecting the cold storage board, the thickness of the color steel of the cold storage panel must be determined.
Polyurethane cold storage panel
The polyurethane cold storage panel uses lightweight polyurethane as the inner material of the cold storage panel. The advantage of polyurethane is that it has very good heat insulation performance. The exterior of the polyurethane cold storage panel is made of SII, pvc color steel plate and stainless steel plate components. Due to the large temperature difference between the inside and outside of the plate, the temperature spreads, which makes the cold storage more energy-saving and improves the working efficiency of the cold storage.
