Cold storage is generally prefabricated by the manufacturer, with fixed length, width and thickness. Pay attention to the density of the warehouse plate and the thickness of the steel plate when purchasing. The thickness of the steel plate of the regular cold storage board manufacturer is generally above 0.4MM, and the foaming density of the cold storage board is 38KG ~ 40KG/m3 per cubic meter according to the national standard.

The choice of cold storage board is very important for cold storage, because cold storage is different from ordinary warehouse, the temperature in cold storage is generally low, and the requirements for temperature, humidity and environment are relatively high. Therefore, the cold storage board manufacturers remind, in the choice of cold storage board, we should pay attention to the choice of temperature control better cold storage board. If the choice is improper, the temperature in the cold storage is difficult to control, which may easily cause the products stored in the cold storage to deteriorate, or make the cold storage refrigeration compressor work frequently, wasting more resources and increasing costs.
Today, cold storage board manufacturers to briefly understand the characteristics of cold storage board, interested friends to see.
1. Cold storage plate rigid polyurethane has low thermal conductivity and good thermal performance. When the density of rigid polyurethane is 35~40kg/m3, the thermal conductivity is 0.018~0.024w/(MK ), which is about half of EPS, which is lower than the thermal conductivity of all insulation materials at present.
2. Rigid polyurethane has moisture-proof and waterproof properties. The closed cell rate of rigid polyurethane is above 90%, which is a hydrophobic material. It will not increase the thermal conductivity due to moisture absorption, and the wall surface will not seep water.
3. Rigid polyurethane fireproof, flame retardant, high temperature resistant. After adding flame retardant, polyurethane is a flame retardant self-extinguishing material, the softening point can reach more than 250, and it only decomposes at a higher temperature. In addition, the polyurethane in the cold storage plate will form carbon deposits on the surface of its foam during the combustion process, which helps to isolate the foam below. Can effectively prevent the spread of flame. Moreover, polyurethane does not produce harmful gases at high temperatures.
4. The polyurethane board has excellent heat insulation performance. Under the same heat insulation requirements, it can reduce the thickness of the outer protective structure of the building and increase the indoor space.
5. Anti-deformation, not easy to break, stable and safe gloss.
6, polyurethane material porosity structure is stable, basically closed cell structure, not only has excellent heat insulation performance, but also has good freeze-thaw and sound absorption. regular the use and maintenance, the average life of rigid foam polyurethane insulation structure can reach more than 30 years. The structure of the refrigeration board is not affected by external factors such as dryness, humidity, and electrochemical corrosion during the service life, under normal use conditions, and can ensure that it is not affected by the growth of insects, fungi, algae and rodents.
7, comprehensive cost-effective. The unit price of rigid polyurethane foam is higher than other traditional insulation materials, but the increased cost is offset by greatly reduced heating and cooling costs.
To sum up, the cold storage board manufacturers to remind the majority of friends,: choose the right cold storage plate to better maintenance of cold storage.
