How is the cold room panels of the steel structure cold storage insulated?
The cold room panels specially used for steel structure cold storage produced by Henan Canglong Steel Structure Engineering Co., Ltd. uses German BASF pentane B1 foaming agent. The foam has a high closed cell rate and good stability. The formed core material can reach B1 level resistance. flammability level. The new generation of polyurethane PIR cold storage panel bonded by this core material and high-strength steel plate brings users an energy-saving cold storage enclosure system with lower heat conduction and higher thermal insulation performance.
How does the cold room panel achieve insulation?
The cold room panels of steel structure cold storage rely on sandwich materials with low thermal conductivity. Common sandwich materials include polystyrene foam (EPS), extruded polystyrene board (XPS) and polyurethane (PU). Among them, polyurethane has better dimensional stability, lower thermal conductivity and better integrity than extruded polystyrene, but its use is also limited by fire resistance. Polyisocyanurate (PIR), which has appeared in recent years, has better fire resistance than polyurethane (PU), and can reach the B1 level stipulated by the national standard. It has strong compression resistance, low thermal conductivity, and excellent dimensional stability. Wide application prospects.
The cold storage panel adopts a new generation of polyurethane PIR pentane B1 core material with strong thermal insulation performance, lower heat conduction, no CFC emissions, and meets the national B1 fire protection requirements. It is a new generation of environmentally friendly high-quality building materials. Manufacturers who want to purchase cold room panels must pay attention to identifying the core material of cold storage panels. General insulation materials can pass the test and be put into the market as long as they reach the B level. However, the insulation material of the cold room panel still needs to choose the polyisocyanurate (PIR) material with lower thermal conductivity and more advantages.
