Cold storage board/PU board

Cold storage panels are generally pre-produced by manufacturers and have fixed lengths, widths and thicknesses. High and medium temperature cold storage generally use 10 cm thick plates, while low temperature and frozen storage generally use 12 cm or 15 cm thick plates; so if It is not a predetermined warehouse board. When purchasing, you must pay attention to the density of the warehouse board and the thickness of the steel plate.

The three important factors of cold storage panels are the density of the cold storage panels, the thickness of the steel plates on both sides, and the load-bearing capacity. The density of the cold storage insulation board is high, so the amount of polyurethane required for foaming the board will increase. This will increase the thermal conductivity of the polyurethane board, which will reduce the insulation performance of the cold storage board and increase the cost of the board. If the foaming density is too low, it will cause The load-bearing capacity of cold storage panels has decreased. After testing by relevant departments, the foam density of polyurethane cold storage insulation panels is generally 35-43KG. Some manufacturers reduce the thickness of color steel in order to reduce costs. The reduced thickness of color steel directly affects the service life of the cold storage. When choosing cold storage panels, you must determine the thickness of the color steel for cold storage panels.

The choice of polyurethane cold storage panels is very important for cold storage, because cold storage is different from ordinary warehouses. The temperature inside the cold storage is generally relatively low, and the air temperature, humidity, and environmental requirements are relatively high. is high, so when we choose polyurethane cold storage panels, we must pay attention to choosing polyurethane cold storage panels that have better temperature control. If the polyurethane cold storage panels are not selected well and the temperature inside the cold storage is difficult to control, it will easily lead to storage in the cold storage. The products in the cold storage deteriorate, or the cold storage refrigeration compressor is made to work frequently, which wastes more resources and increases costs. Choosing the right panels can better maintain your cold storage.
