Can polyurethane sandwich panels be used for cold storage?
Yes.
Polyurethane cold storage board is a good insulation of lightweight polyurethane as the inner material, the external by the SII, PVC color steel plate and stainless steel plate made of polyurethane sandwich panels, the advantage of doing so is to prevent cold storage board because of the large temperature difference between inside and outside The temperature of the spread, so that the cold storage more energy-efficient, improve the efficiency of cold storage. Luoyang Tianjiang chemical production of polyurethane cold storage board also has fire, flame retardant and high temperature and other excellent features.
Polyurethane sandwich panels can be used to make cold storage, polyurethane sandwich panels are two-component liquid polyurethane AB material through the prefabricated production line.
Polyurethane sandwich board in the polyurethane material is isocyanate and polyether as the main raw material, in the foaming agent, catalyst, flame retardants and other additives under the action of foam polymer. Polyurethane rigid foam is a new type of synthetic material with insulation and waterproof function, its thermal conductivity is low, only 0.022 ~ 0.024W / (m · Κ), equivalent to half of the extruded plate, is the thermal conductivity of all insulation materials lowest.
Cold storage polyurethane insulation generally have two kinds of technology, one is the use of sandwich panel on-site stitching, and another process is the use of polyurethane spray coating on-site spraying foam, compared to the first process, the second process because it is on-site spraying foam Any seams, greatly avoid the phenomenon of hot and cold joints, insulation effect is better than the first process.
