The three important factors of cold storage panels are their density:
First, the thickness and load-bearing capacity of the side steel plates. If the density of the cold storage insulation board is high, the foaming of the board will increase the amount of polyurethane used. At the same time, the thermal conductivity of the polyurethane board will increase, 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, the load-bearing capacity of the cold storage plate will decrease. According to the tests conducted by relevant national departments, the foaming density of polyurethane insulation boards for cold storage is generally set at 35-43 kilograms as the standard. Some manufacturers reduce the thickness of color steel to cut costs, which directly affects the service life of cold storage. When choosing cold storage panels, it is essential to determine the thickness of the color steel inside the cold storage panels.
Cold storage panel
The cold storage plate adopts lightweight polyurethane as the internal material of the cold storage plate. The advantage of polyurethane is its excellent heat insulation performance. The shell of the polyurethane cold storage plate is made of SII, pvc color steel plate and stainless steel plate. The advantage of doing this is to prevent the temperature diffusion inside the cold storage plate caused by the large temperature difference between the inside and outside, thereby making the cold storage more energy-efficient and improving its working efficiency.
Select cold storage panels:
The selection of cold storage panels is of great significance for cold storage, as it is different from ordinary warehouses. The temperature inside a cold storage is generally lower, and it has higher requirements for air temperature, humidity and the environment. Therefore, when choosing polyurethane cold storage plates, it is necessary to pay attention to selecting those with better temperature control. If the polyurethane cold storage panels are not properly selected, it will be difficult to control the temperature inside the cold storage, which may lead to the deterioration of the products stored in the cold storage or the refrigeration of the cold storage. Only by choosing the right plates can the cold storage be better maintained.
