Vermiculit

We produce the finest quality vermiculite of following Mesh categories 2 4 6 8 12 20 40 60 100 325 800 1250 Main purpose introductionVermiculite is a hydrate, in blocks, sheets. The layer of water molecules is at high temperature burning, the volume increased 6-15 times. Rich in nitrogen, phosphorus, potassium, aluminum, iron, magnesium, silicate and other components. Layer of vermiculite have a higher charge, so it has a high cation exchange capacity and high cation exchange adsorption. Features are: light, water and nitrogen adsorption properties, does not rot, can be used 3-5 years (not like humus, coconut shell suits, and other perishable).The new vermiculite after high temperature roasting, its volume can expanded to several or tens times rapidly, the average density of vermiculite is 100-130kg/m 3 after expansion, with small air layer, so it is an excellent heat insulation, sound absorption, resistance to freezing-thawing of building materials, industrial packing, coating and refractories, thermal conductivity, density at 50-200kg/m3, is a good insulation material. The good quality of expanded vermiculite, the maximum using temperature up to 1100°C. Besides, expanded vermiculite has good electric insulation. Has the property of light density, cold-resist, heat insulation, sound absorption. Can be widely used in construction, electric power, petroleum, chemical, metallurgy, textile, agriculture and food industries. The construction industry for used in thermal insulation, sound, finishing materials, in agriculture, can used as soil improvement, fertilizer carrier’s auxiliary materials, be animal feed, deodorant, animal drugs, pesticides, etc., can also be used as pesticides, fungicides, disinfectant, organic compounds (camphor), And provide a good media for the storage of vegetables and other rare plant roots, stems and leaves. Vermiculite has properties of adsorption for radioactive elements, also can handle some waste water of radioactive elements.
