What is the suitable environment for perlite board? Dacheng Xiangdong Insulation Refractory Material Factory 13473696600 15731614448
Perlite insulation boards have different degrees of defects: perlite in the moisture-containing state, prone to corrosive calcium oxide, and because it retains moisture for a long time, it is not easy to use in low temperature environment; glass fiber is easy to absorb moisture, pearl Rock insulation board is not suitable for low temperature environment, nor suitable for temperature environment above 540 °C; mineral wool also has water absorption, not suitable for low temperature environment, can only be used in high temperature environment without moisture; polyurethane foam and polystyrene foam It is not suitable for use at high temperatures, and it is flammable, shrinking, and producing toxic gas. Foam glass is not suitable for thermal shock, and should not be used in a state where temperature changes rapidly. Therefore, in order to overcome the shortage of thermal insulation materials, countries have developed lightweight multifunctional functions. Composite insulation material.
Faucets Hose
