Recently, people who have carried out cold storage construction are choosing to use polyurethane cold storage boards for the construction of cold storage bodies, why do people choose polyurethane cold storage boards?Polyurethane cold storage panelsWhat are the advantages for people to choose, and the following will give you a detailed analysis.
Polyurethane cold storage panelsThe embodiment of the advantages is also quite obvious, as follows:
1. Polyurethane cold storage board is fireproof, flame retardant and high temperature resistant. Polyurethane is a flame-retardant, self-extinguishing material after adding flame retardants. In addition, when polyurethane burns, it forms ash on the surface of its foam, which helps to isolate the foam underneath. It can effectively prevent the spread of fire. In addition, polyurethane does not produce harmful gases at high temperatures.
2. Strong deformation resistance, not easy to crack, stable and safe structure.
3. The porosity structure of polyurethane material is stable, basically closed-cell structure, which not only has excellent thermal insulation performance, but also has good freeze-thaw resistance and sound absorption. The average life of rigid foam polyurethane insulation structure can reach more than 30 years under normal use and maintenance conditions. It can be achieved under normal conditions of use during the life of the structure, in dry, wet or galvanic corrosion, as well as because the unit price of insects, fungi or algae foam is higher than that of other traditional insulation materials, but the increased cost will be offset by a significant reduction in heating and cooling costs.
4. Hard polyurethane has low thermal conductivity and good thermal performance. When the bulk density of rigid polyurethane is 38-45 m, the thermal conductivity coefficient is only 0018g-0.023w/(m.k), which is equivalent to about half of EPS.
5. Polyurethane cold storage board has moisture-proof and waterproof performance. The closed cell rate of rigid polyurethane is more than 90%, which is a hydrophobic material, and will not increase the thermal conductivity due to moisture absorption, and the wall will also seep water.
6. Because the polyurethane material has excellent thermal insulation performance, it can reduce the thickness of the building envelope structure and increase the indoor usable area under the same thermal insulation requirements.
7. Convenient quality inspection, because the surrounding skin is removed during the cutting process, the quality of the plate is clear at a glance, which ensures the thermal insulation effect of the finished product. The thickness can be produced and processed according to user requirements.
8. There are many varieties of polyurethane cold storage boards, which can be customized according to customer needs.
