The cold storage board uses lightweight polyurethane as the inner material of the cold storage board, and the advantage is that the heat insulation performance is very good. Poly appearance is composed of SII, PVC color steel plate and stainless steel plate components. The cold storage board manufacturer introduces that the advantage of this is to prevent the temperature diffusion in the cold storage board caused by the large temperature difference between inside and outside, thus making the cold storage more energy-saving and improving the working efficiency of the cold storage.
Can be so respected, polyurethane cold storage board naturally has its outstanding advantages.
1. Compared with other materials, when the density of rigid polyurethane is 0.035~0.04, the thermal conductivity is only 0.018~0.023w/(m. k), which is only half of EPS, which is the low thermal conductivity of all thermal insulation materials at present.
2. It can be fireproof and high temperature resistant. As long as flame retardant is added, it can become a high temperature resistant material and soften only when the temperature reaches 250. And when it is burned by flame, ash will form on the surface, which effectively protects the foam layer below from high temperature, thereby preventing the fire from spreading. Moreover, polyurethane does not produce harmful gases after combustion, and is a safe industrial material.
3. It is basically a closed-cell structure, which makes it waterproof and moisture-proof, and can also effectively sound insulation. Under normal use and perfect maintenance, the effective life can reach more than 30 years, which is much higher than other materials.
Cold storage board manufacturers said that the construction of fireproof cold storage can not be separated from the fire protection and environmental protection of the cold storage board. So, how to choose a good polyurethane cold storage board for construction, it is how to carry out environmental protection fire?
The board is made of polyurethane, which has good thermal insulation and is fireproof. It is the preferred choice for the construction of fire protection and environmental protection cold storage.
Low thermal conductivity, good thermal performance, good moisture-proof and waterproof performance. The closed cell rate is above 90%. It is a hydrophobic material. The thermal conductivity will not increase due to moisture absorption, and the wall will not seep water.
After adding flame retardants, polyurethane is a flame-retardant self-extinguishing material with a softening point of more than 250, and it will only decompose at higher temperatures. In addition, when burning, ash is formed on the surface of the foam, which helps to isolate the foam below and can effectively prevent the fire from spreading. And no harmful gases are produced at high temperatures.
Cold storage board manufacturers, in the choice of cold storage board, we must pay attention to choose a better temperature control, to ensure that the internal temperature is constant and low. If the use of inferior, not only will make the internal temperature difficult to control, resulting in product deterioration, but also make the refrigerator need to work frequently, increase the cost of refrigeration in the cutting will remove the skin, so that the quality of the whole plate at a glance, then can be a good inspection of the plate is good or bad.
