What are the main ingredients of vermiculite fireproof board?
Vermiculite fireproof board is a new kind of inorganic material. It is made of expanded vermiculite as main raw material and mixed with a certain proportion of inorganic binder.
Vermiculite is a kind of layered magnesium silicate, which is similar in shape to mica. Because it is bent when it is hot and inflated, it is similar to leech, so it is called vermiculite. The utility model has the advantages of heat insulation, heat resistance, frost resistance, antibiosis, fire protection, sound absorption and the like
Vermiculite (Vermiculite) (Mg, Ca) 0.3-0.45 (H2O) n{(Mg, Fe3, Al) 3[(Si, Al) 4O12] (OH): 2} is a layered structure containing magnesium aluminum silicate water secondary metamorphic minerals, ore shape like mica, usually consist mainly of black mica (gold) by heat liquid alteration or weathering, because of the heat loss during the expansion was a deflection shape similar to the shape of leech, called vermiculite.
