Rich in nitrogen, phosphorus, potassium, aluminum, iron, magnesium, silicate and other ingredients. Vermiculite have a higher charge of several layers, it has a high cation exchange capacity and strong cation exchange adsorption capacity. Because it was a deflection shape when thermal expansion, shape resembles leeches (leech), so called vermiculite. Expanded vermiculite insulation, anti-freeze, anti-bacterial, fire, acoustic, light, excellent performance, but not acid, its dielectric properties are relatively poor. Vermiculite uses: 1, the expanded vermiculite slab on the roof, can play a very good effect compartment temperature, make building homes cool. Vermiculite brick brick high-rise building wall panels, can play a sound, fire protection, thermal and other effects, but also reduce the load floor. 2, vermiculite used in the greenhouse, with loose soil, good air permeability, water resistance, and high soil temperature is conducive to the growth of crops, 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 currently used in medicine and health, animal feed and other industries.
