Expanded perlite insulation brick

Characteristic:
Expanded perlite insulation brick is one of the thermal insulation refractory products, mainly chemical composition is perlite. According to different binder, Expanded perlite insulation brick can be classified cement combined with perlite insulation birck, soluble glass combined with perlite insulation brick, phosphate with perlite insulation brick and bitumen combined with perlite insulation birck, etc. Following is the physical index of Cement combined with expanded perlite insulation brick. It has good insulation properties, good heat resistance, good acid and alkali erosion resistance, non-toxic, harmless, moisture absorption rate is very small, long-term preservation and non-degenerate when used after long term. The Expanded perlite insulation brick has a wide using temperature range. It not only can be used as a medium temperature thermal insulation material, but also as an insulation material. The maximum operating temperature is about 1000 degrees, the minimum temperature is to -200 degrees.
Expanded perlite insulation brick application:
It is widely used in the thermal equipment, refrigeration equipment and refrigeration engineering adiabatic of metallurgical, chemical, electrical, construction, defense industries and other departments.
