Polyurethane cold storage boardProduct Details
Polyurethane cold storage board

The polyurethane cold storage board uses light polyurethane as the inner material of the cold storage board. The advantage of polyurethane is that the thermal insulation performance is very good. The exterior of the polyurethane cold storage board is composed of color steel plate and stainless steel plate components. The advantage of this is to prevent the temperature transmission of the cold storage board due to the large internal and external temperature difference, so as to make the cold storage more energy-saving and have the thermal insulation effect like a refrigerator, Reduce power consumption and improve refrigeration efficiency.

1. Rigid polyurethane has low thermal conductivity and good thermal performance. When the density of rigid polyurethane is 35 ~ 40kg / m3, the thermal conductivity is only 0.018g ~ 0.023w / (m.k), about half of EPS, which is the lowest among all thermal insulation materials.

2. Polyurethane cold storage board has moisture-proof and waterproof properties. The closed cell rate of rigid polyurethane is more than 90%, which is a hydrophobic material. It will not increase the thermal conductivity due to moisture absorption, and the wall will not seep.

3. Polyurethane cold storage board is fireproof, flame retardant and high temperature resistant. Polyurethane is a flammable self extinguishing material after adding flame retardants. Its softening point can reach above 250 degrees Celsius. It will decompose only at higher temperature. In addition, polyurethane will form ash on its foam surface when burning, which will help isolate the foam below. It can effectively prevent the spread of fire. Moreover, polyurethane does not produce harmful gas at high temperature.

4. Due to the excellent thermal insulation performance of polyurethane plate, under the same thermal insulation requirements, it can reduce the thickness of the outer envelope of the building and increase the indoor use area.

5. The porosity structure of polyurethane material is stable and basically closed cell structure. It not only has excellent thermal insulation performance, but also has good freeze-thaw resistance and sound absorption. The average service life of rigid polyurethane insulation structure can reach more than 30 years under normal use and maintenance conditions. The unit price of foamed materials due to insects, fungi or algae is higher than that of other traditional thermal insulation materials under the normal service conditions during the service life of the structure, dry, wet or electrochemical corrosion, but the increased cost will be offset by the substantial reduction of heating and cooling costs.

6. There are many specifications and varieties, and the unit weight range: (40-60kg / m3); Length range: (0.5m-4m); Width range: (0.5m-1.2m); Thickness range: (20mm-200mm).

7. High cutting precision, thickness error ± 0.5mm, so as to ensure the flatness of the finished product surface.

8. It is convenient for quality inspection. Since the surrounding epidermis is removed in the cutting process, the quality of the plate is clear at a glance, ensuring the thermal insulation effect of the finished product.
