People who have recently built cold storage are choosing to use polyurethane cold storage insulation board for the construction of cold storage body. Why do people choose polyurethane cold storage insulation board? What are the advantages of polyurethane cold storage insulation board for people to choose from? Here is a detailed analysis for everyone.
The embodiment of the advantages of polyurethane cold storage insulation board is also quite obvious, as follows:
1. Polyurethane cold storage board is fireproof, flame retardant and high temperature resistant. After adding flame retardant, polyurethane is a non-flammable self-extinguishing material. Its softening point can reach above 250 ℃, and it will decompose only at higher temperatures: in addition, polyurethane will be on its foam when it is burned 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.
2. Strong anti-deformation ability, not easy to crack, stable and safe facing.
3, polyurethane material porosity structure is stable, basically closed pore structure, not only excellent thermal insulation performance, but also freeze-thaw resistance, sound absorption is also good. The average service life of rigid polyurethane insulation structure can reach more than 30 years under normal use and maintenance conditions. It can be done in the life of the structure under normal conditions of use, in dry, wet or electrochemical corrosion, as well as due to insects, fungi or algae raw foam material unit price than other traditional insulation materials, but the increase in costs 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 is only 0.018g-0.023w/(m.k), which is about half of EPS, which is the lowest thermal conductivity of all thermal insulation materials at present.
5, polyurethane cold storage insulation board, with moisture-proof, waterproof performance. The closed cell rate of rigid polyurethane is more than 90%, which is a hydrophobic material. It 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, in order to achieve the same insulation requirements, can reduce the thickness of the building envelope structure, thereby increasing the indoor use area.
7, the cutting precision is high, the thickness error is 0.5mm, so as to ensure the flatness of the surface of the finished product.
8. Convenient quality inspection. Since the surrounding skin is removed during the cutting process, the quality of the board is clear at a glance, ensuring the insulation effect of the finished product. Thickness can be produced and processed according to user requirements.
9, many varieties of specifications, completely customized according to customer needs.
