Characteristics of environmental protection cold storage and polyurethane cold storage insulation board
Frozen cold storage can not be separated from the environmental protection type of cold storage plate, polyurethane cold storage board with moisture-proof, waterproof performance. The closed cell rate of rigid polyurethane is above 90%, which is a hydrophobic material, and will not increase the thermal conductivity due to moisture absorption, and the wall will not seep.
Polyurethane cold storage board fireproof, flame retardant, high temperature resistant. After adding flame retardants, polyurethane is a non-flammable self-extinguishing material. Its softening point can reach more than 250 degrees Celsius, and it will decompose only at higher temperatures: in addition, polyurethane will be on its foam when it burns Ash is formed on the surface, this layer of ash helps isolate the foam below. Can effectively prevent the spread of fire. Moreover, polyurethane does not generate harmful gases at high temperatures.
Because the polyurethane sheet has excellent heat insulation performance, in order to achieve the same insulation requirements, can reduce the thickness of the building envelope, thereby increasing the indoor use area. Strong deformation resistance, not easy to crack, stable and safe finish. Polyurethane material porosity structure is stable, basically is a closed pore structure, not only excellent thermal insulation performance, and resistance to freeze-thaw, sound absorption is also good. The average life of rigid polyurethane foam insulation structure can reach more than 30 years under normal use and maintenance conditions.
Cold storage buildings should prevent the diffusion of water vapor and the penetration of air. Outdoor air intrusion not only increases the cold consumption of cold storage, but also brings moisture into the warehouse. The condensation of moisture causes the building structure, especially the heat insulation structure, to be damaged by moisture and freezing. Therefore, a moisture-proof heat insulation layer should be set up to make the cold storage building have good sealing and moisture-proof vapor-proof performance.
The foundation of cold storage is affected by low temperature, and the water in the soil is easy to be frozen. Due to the volume expansion of the frozen soil, it will cause ground rupture and deformation of the entire building structure, which will seriously make the cold storage unusable. To this end, the low temperature cold storage floor in addition to the effective insulation layer, the insulation layer must also be processed to prevent the soil from freezing.
Environmental protection cold storage used in the cold storage board, can be done in the life of the structure under normal conditions of use, in dry, wet or electrochemical corrosion, and because of insects, fungi or algae raw foam material unit price than other traditional insulation material unit price is high, but the increase in the cost will be offset by a substantial reduction in heating and cooling costs.
