Polyurethane rock wool Sandwich panel is widely used in cold storage, which is green, environmentally friendly, energy-saving and healthy. The advantages of polyurethane rock wool board widely used in cold storage are:
1. The light polyurethane foam is used as the lining material of the cold storage plate. The advantage of polyurethane rock wool board is good thermal insulation performance. The outer wall PU is composed of SII, PVC color steel plate and stainless steel plate. Its advantage is that it can prevent temperature diffusion caused by excessive internal and external temperature difference, thus saving energy and improving the working efficiency of cold storage.
2. Polyurethane rock wool Sandwich panel is fire-resistant, flame retardant and high-temperature resistant. After adding flame retardant, polyurethane rock wool panel becomes a flame-retardant self-extinguishing material, its softening point reaches more than 250, and it will decompose only at high temperature. In addition, when polyurethane rock wool board burns, ash will form on the surface of foam to help isolate the foam below. It can effectively prevent the spread of fire. Polyurethane rock wool board will not produce harmful gas under high temperature.
3. Due to the excellent thermal insulation performance of polyurethane rock wool board, under the same thermal insulation requirements, it can reduce the thickness of the building outer protective structure and increase the indoor use area.
4. Strong deformation resistance, no cracking, smooth, stable and safe surface. PU has stable porous structure, which is basically closed pore structure. It not only has excellent thermal insulation performance, but also has good antifreeze and sound absorption performance. After normal use and maintenance, the service life of the thermal insulation structure of rigid foam plastic thermal insulation structure can reach more than 30 years on average. During the service life of the structure, the unit price of polyurethane rock wool board is higher than that of other traditional thermal insulation materials under the normal use conditions of dry, wet or electrochemical corrosion, but the increased cost will be offset by the greatly reduced heating and cooling costs.
