Cold storage plates are generally pre-produced by cold storage plate manufacturers and have fixed length, width and thickness. High and medium temperature cold storage generally use 10cm thick plates, while low temperature storage and frozen storage generally use 12cm or 15cm thick plates. Therefore, if it is not a predetermined warehouse board, attention should be paid to the density and the thickness of the steel plate when purchasing. The thickness of the steel plate of the cold storage plate manufacturer is generally above 0.4MM, the foaming density of cold storage warehouse board is 38KG ~ 40KG/m3 per cubic meter according to the national standard.

The cold storage board uses lightweight polyurethane as the internal material. The advantage is that the thermal insulation performance is very good. The appearance of polyurethane cold storage board is composed of SII, pvc color steel plate and stainless steel plate components. The advantage of this is to prevent the temperature diffusion caused by the large temperature difference between inside and outside, so as to make the cold storage more energy-saving and improve the working efficiency of the cold storage. Below, the advantages of polyurethane by the cold storage board manufacturers.
Cold storage board has the following advantages:
1. Fire prevention, flame retardant, high temperature resistance. After adding flame retardants, polyurethane is a flame-retardant self-extinguishing material, its softening point can reach more than 250 degrees Celsius, and it will only decompose at higher temperatures. In addition, ash is formed on the surface of the foam when burning, which helps to isolate the foam below. Can effectively prevent the spread of fire. And no harmful gases are produced at high temperatures.
2. Due to the excellent thermal insulation performance, under the same thermal insulation requirements, the thickness of the building envelope can be reduced, thereby increasing the indoor use area.
3. Strong anti-deformation ability, not easy to crack, stable and safe finish, stable porous structure, basically closed-cell structure, not only has excellent thermal insulation performance, but also has good freeze-thaw resistance and sound absorption. Under normal use and maintenance conditions, the average life of the insulation structure can reach more than 30 years. Under the normal use conditions of the structure's life cycle, under dry, humid or electrochemical corrosion conditions, the unit price of foam materials made of insects, fungi or algae is higher than other traditional insulation materials, but the increased cost will be heating and cooling costs Offset by a substantial reduction.
4. Strong anti-deformation ability, not easy to crack, stable and safe finish.
5. Low thermal conductivity, good thermal performance. When the bulk density of rigid polyurethane is 38-45/m, the thermal conductivity is only 0.018g-0.023w/(m.k), which is about half of EPS, which is the lowest thermal conductivity of all thermal insulation materials at present.
6. High cutting accuracy and 0.5 thickness error ensure the flatness of the finished surface.
7. To facilitate quality inspection. Since the skin around the plate is removed during cutting, the quality is clear at a glance, ensuring the heat preservation effect of the finished product, and the thickness can be produced and processed according to user requirements.
8. specifications of many varieties, can be fully customized according to customer needs.
