1.Usually used in special equipment, polyethylene is a very good raw material, after a certain proportion, it can be appropriate foam density, good insulation effect, high weight bearing cold storage insulation materials.Polyurethane plates are very good, well insulated and not moisture absorbing, but at a slightly higher price
2.Cold storage building thermal insulation materials should have good thermal insulation performance, economical and reasonable, suitable for the choice of thermal insulation materials.However, the construction cost of cold storage is high, polystyrene high water absorption, poor heat insulation, but low old original.Do site assembly, the advantage is convenient construction, fast speed, mobile
3.The choice of cold storage is very important for refrigeration, because cold storage is different from other warehouses.Select a suitable plate for the maintenance of the cold storage.The structure of cold storage board and medical cold storage requires high temperature, high humidity and other environmental requirements.Therefore, when choosing the cold room panel, should be paid attention to the material and insulation strength of the panel.
When selecting materials, please pay more attention to the density of the polyurethane and the thickness of the steel plate.The thickness of steel plate of regular manufacturers should be more than 0.4 mm. According to national standards, the foaming density of cold storage panel is over 40kg/m3.Now on the market, the main raw materials of special cold storage board for cold storage project are polyphenylene, polyethylene and polyphenylene grease. The density of thermal insulation material foamed by polyphenylene is thin, and the thermal insulation coefficient is not very high; After a certain proportion of polyethylene, it can foam cold storage insulation materials with appropriate density and good thermal insulation effect, and has high load-bearing capacity; Polyphenylene resin has strong water absorption, but poor heat insulation. Therefore, the polyurethane sandwich board has the best performance. Although the price is slightly higher, the polyurethane board has the best thermal insulation performance and does not absorb moisture.
