Cold storage insulation design recommendations

 

Recommendation 1: ground using Type II or Type III polyurethane.
Insulation materials PU-II type PU-III type XPS
Thermal conductivity ≤ 0.024 ≤ 0.024 ≤ 0.028
Compressive strength ≥ 250KPa ≥ 350KPa ≥ 350KPa
Energy loss 0% 0% 20%
Combustion performance heatset heatset thermoplastic
Recommendation 2: on the outside and then spray polyurethane foam sandwich panels.
There seam insulation sheet, because the cross-sectional area, could not fully adhered, at low temperature joints become large.
Then spray the outside of the plate a polyurethane foam, you can solve this problems.
Recommendation 3: The use of environmentally friendly two-component cyanide condensate gas barrier layer.
One component cyanide condensate: viscosity, solvent must be added to diluted xylene, acetone, etc., only about 60% solids content. Commonly used manual brushing construction.
Two-component cyanide condensate: without any thinner, 100% solids, high-pressure airless spray equipment.
