The choice of sandwich panel for cold room is very important because the cold storage is different from the ordinary warehouse, the temperature in the cold storage is generally low, and the requirements for air temperature, humidity and environment are relatively high, so we should pay attention to the choice of the cold storage panel with better temperature control, if the cold storage panel If the temperature in the cold storage is difficult to control due to poor panel selection, it will easily lead to deterioration of products stored in the cold storage, or make the refrigeration compressor in the cold storage work frequently, waste more resources and increase costs. Choose the right panel to better maintain cold storage. The cold storage panel is generally classified according to the materials. The most commonly used materials are polyethylene and polyphenylene. In addition to these two materials, there is also a very good performance. Polyurethane sandwich panel and polyphenylene cold storage panel are generally used in special equipment because the density of the insulation materials is relatively thin and not enough for insulation, while polyethylene is better and the insulation effect is relatively good. Of course, the best one is polymerization, the price of ammonia ester cold storage panel is relatively high. But polyurethane cold storage panel with excellent thermal insulation performance, in the cold storage industry, has won a very wide use.
Sandwich panel for cold room is generally produced in advance by the manufacturer, with a fixed length, width, and thickness. High and medium temperature cold storage panels are generally 10cm thick, while low temperature and freezing storage panels are generally 12cm or 15cm thick. Therefore, if they are not the predetermined storage panels, attention should be paid to the density of the storage panels and the thickness of the steel panels. The thickness of the normal manufacturer's steel panels is generally less than 0.4mm The foaming density of the cold storage panel is 38kg-40kg / m3 according to the national standard.
