Stainless steel water tank insulation insulation material: polyurethane foam core medium can be, polystyrene, polypropylene foam, rock wool, PEF; inner can be food-grade stainless steel, galvanized steel, aluminum or color plate. Outer material can be used generally stainless steel, galvanized steel, aluminum or color plate. Insulation works: The holding tank is stainless steel plate, color steel plate as the surface layer of closed-cell polystyrene flame retardant self-extinguishing material such as polyurethane core board or by optimizing the combination of the inner and outer layers together to achieve the best insulation effect, The tank has a beautiful appearance, high mechanical strength, excellent performance, easy assembly and other superior features.
