supply polyurethane Thermal insulation module and thermal insulation water tank must be selected; Polyurethane insulation module
Polyurethane is a thermal insulation material with good thermal insulation effect and high cost performance. be used for Stainless steel water tank Thermal insulation, with an average heat loss of 4 ℃/day. This product is made of polyurethane raw materials secondarily mixed by our professional technicians and foamed in professional molds. The utility model has the advantages of full and beautiful appearance, no shrinkage, high hardness, good heat preservation effect, etc. It is a better choice for stainless steel insulated water tank.
1. Rigid polyurethane has low thermal conductivity and good thermal performance. When the density of rigid polyurethane is 35~40kg/m3, the thermal conductivity is only 0.018~0.024w/(m.k). The density of our company can reach 80 kg/m3, about half of EPS, which is the low thermal conductivity of all insulation materials at present.
2. Rigid polyurethane has moisture-proof and waterproof properties. 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 not leak water.
3. Rigid polyurethane is fireproof, flame retardant and high temperature resistant. After adding flame retardant, polyurethane is a flame retardant self extinguishing material (Grade B2), its softening point can reach more than 250 ℃, and it will decompose only at higher temperatures. In addition, polyurethane will form carbon deposits on its foam surface when burning, which will help isolate the foam below. It can effectively prevent flame spread. Moreover, polyurethane does not produce harmful gases at high temperatures.
4. Due to polyurethane board It has excellent thermal insulation performance, which can reduce the thickness of the building's outer enclosure structure and increase the indoor use area under the same thermal insulation requirements.

5. It has strong deformation resistance, is not easy to crack, and the finish is stable and safe.
6. The porosity structure of polyurethane material is stable, basically closed pore structure, which not only has excellent thermal insulation performance, but also has good freeze-thaw resistance and sound absorption. The average service life of rigid polyurethane insulation structure can reach more than 30 years under the condition of normal use and maintenance. Under normal service conditions during the service life of the structure, the structure will not be damaged in dry, wet or electrochemical corrosion, as well as due to the growth of insects, fungi or algae, or due to rodent damage and other external factors.
7. The comprehensive cost performance ratio is low. Although the unit price of rigid polyurethane foam is higher than that of other traditional insulation materials, the increased cost will be offset by the substantial reduction of heating and cooling costs.
Product use:
The rigid polyurethane insulation board produced by our company can be widely used colour steel Sandwich plate, midpoint air conditioner , building wall materials, cold storage, cold storage room, incubator, stainless steel water tank and other fields
