Vermiculite chemical composition (%) SiO2 Al2 O3 Fe2O3 MgO H2O 37-43 9-17 5-24 11-23 0.5-9 1: the expanded vermiculite slab to the roof, can play a very good effect compartment temperature, so that building homes cool. Vermiculite brick brick high-rise building wall panels, can go to the noise, fire, moisture and other effects, but also reduce the load floor. 2: Vermiculite is used in the greenhouse, with loose soil, good air permeability, water resistance, temperature and other characteristics, it is conducive to crop growth, and can reduce fertilizer inputs. In the nascent soilless cultivation technology, it is the essential raw materials. 3: vermiculite insulation adhesive mix and the amount can be made of an insulating board. 4: Vermiculite is also used in medicine, animal feed and other lines. Crystal chemistry of tetrahedral Al instead of Si film is generally 1/3 ~ 1/2, but also have Fe3 instead of Si. Al, Fe3 instead of Si is the main reason for the charge generating layer. Charge the number of units of the formula is between 0.6 to 0.9. Charge compensation layer on the one hand is replaced by octahedral Al Mg cause, the other from the interlayer cations. Mg-based interlayer cation can be Ca, Na, K, (H3O), and Rb, Cs, Li, Ba and the like. Octahedral sheet main cation is Mg, can also have Fe3, Al, Cr, Fe2, Ni, Li and the like. Interlayer water content depending on the interlayer cation hydration capacity and ambient temperature and humidity. Mg-containing high water hydration capacity, at high temperature and humidity, single
