Perlite
1. Expanded perlite:
an kind of internal honeycomb-like structure ,white granular material, made from perlite ore that after it is preheated and instantaneously expands under high-temperature calcination.
|
2. Feature:
*White granular (internal honeycomb structure); |
*Nontoxic, tasteless, noncombustible, non-corrosive; |
*Neutral pH value (pH value: 6.5-7.5); |
*Acid resistant and alkali resistant; |
*Light weight, high absorption and insulation capability

4. Applications
Because expanded perlite is good heat insulation, light weight, nontoxic, porous, and abundant reserved and low price, hence it widely used in following fields:
*lightweight construction insulation board, partition board, acoustic board, fireproof board. |
*Insulation materials for industrial furnaces and tubes |
*filtration agent for beer, drinking, food and medicine |
*slag collecting material for steel melting and insulation filler for air separator |
*Filler or expanding agent for rubber, paint, plastic, TNT etc |
*soil adjusting agent, non-soil growing substrate, pesticide cleansing agent. |
