Stainless steel kitchen tanks will use some special materials to collect the materials at the end of the tank, and some have moisture-absorbing material, suction material, suction material, suction material, suction material and suction material. Cotton rock wool uses basalt rock wool as the main raw material, as shown in the picture. After that, man-made inorganic fibers are made by high-speed centrifugal equipment, and special adsorbents and greases are added at the same time, and then heated and solidified to produce cotton-quality products of various specifications. It has the characteristics of low thermal conductivity and high stability. But now the microorganisms in the water storage tank use rock wool, and more use foam board materials.

Polystyrene resin as raw material, through the special process of continuous extrusion foam forming hard foam insulation board.Polystyrene molecular structure itself does not absorb water, the positive and negative sides of the plate have no gaps, the internal for the independent closed bubble structure, is a low thermal conductivity, high compression, moistureproof, airtight, light weight, corrosion resistance, long service life and other advantages.Polystyrene resin is not easy to break, easy to install, easy to cut.

Polyurethane is made of polyisocyanate and polyether polyols or polyester polyols or small molecular polyols, polyamines, water and other chain extenders or crosslinking agents and other materials. By changing the type and composition of raw materials, the product morphology and properties can be greatly changed, and the final product can be obtained from soft to hard.Polyurethane products have the advantages of light capacity, high strength, thermal insulation, sound insulation, flame retardant, cold resistance, anti-corrosion, non-water absorption, simple and quick construction, etc., and the insulation effect is particularly good, but at the same time the price is high.

Rock wool material is often used in stainless steel cold water tank, stainless steel storage tank;Foam board (polystyrene board) is often used in glass fiber reinforced plastic water tank and stainless steel hot water tank;Polyurethane foaming is generally used in stainless steel heating tank, hot water tank, high cost, good insulation effect.
