Expand pearlite is to use pearlite to be made via to calcine hind, he shows grain of white, poriferous shape, namely the surface smooth, wall is thin, beehive shape structure is inside. Accordingly, expand pearlite unit weight is little, It is 40-550kg/m3; thermal conductance commonly low, fireproof temperature is 1280-1360 ° C; Have stock sound insulation and frost resistance at the same time can.
Poriferous Molaishi is heat up high temperature of raw material classics with the day firing, the majority is its crystallization photograph growth of system of Mo Laishi Ju Jing is good, its are acicular crystal makes furcate reticulate structure each other, become namelyPoriferous Molaishi.
Much between brick of light qualitative heat preservation with, low density, rate of hot heat conduction is low it is main note with fireproof temperature, use at the heat insolation of industrial kiln furnace between the adiabatic liner of kiln furnace, decrease medicinal powder hot causticBreak, the heat insolation of managing the sources of energy fireproof material.
