Raw material ?for vermiculite board
?
Vermiculite?is the generic name for laminar, hydrated ferromagnesian-Aluminum-Silicate minerals that resemble mica?in?the?crude?form.?It?has?a?great?number?of?industrial?uses?by?virtue?of?its?expansion?behavior?on?heating.
?
When?heated?rapidly?to?900-1,000 D.C, its interlaminar water turns to steam and causes the minerals layers to exfoliate or sepreate into worm-like pieces. This forms a material with Lower Density, Excellent Insulation properties, Good Absorption, Iron Exchange Capacity, Chemically Stable and Non-toxic.?
?
The above properties make it widely used in Construction, Agriculture and Horticulture and Industrial application.
