Mobile: 18032023929 QQ: 805221314 Manager Fan Vermiculite itself is a magnesium aluminum silicate secondary water metamorphic minerals, shape like mica, usually by black (K) mica by hydrothermal alteration or weathering, because When heated water loss was its expansion deflection shape, shape resembles leech, it said vermiculite. After calcination the rapid expansion of its volume can be 8-20 times the proportion of the expanded 130-180kg / m3, it has strong insulation properties, swelling, cation exchange and adsorption; Vermiculite also has a good absorbent , noise, heat insulation and fire resistance, resistance to cold resistance, chemical stability expanded vermiculite. Insoluble in water. pH value of 7-8. Non-toxic, tasteless, no side effects. The main application areas of vermiculite: Construction: lightweight materials: lightweight concrete aggregate (light wall powder, light mortar). Heat-resistant materials: wall materials, fire board, fire mortar, bricks. Insulation, sound-absorbing insulation material: underground pipes, greenhouse pipe insulation materials, interior and tunnel interior walls and ceilings metallurgical public places: coated sheet steel, iron, cast steel slag rise building cladding materials, Vermiculite bulk agriculture, forestry, horticulture: Vermiculite is a mineral mica secondary siliceous hydrated magnesium aluminum silicate, aluminum, magnesium, iron hydrous silicate, by a thin layer of laminated constitution. Light and porous texture, good air permeability, water absorption and some water retention, and contains flowers for absorption and utilization of magnesium, potassium and other elements. Vermiculite has a high buffering and ion exchange capacity, ventilation or, use it as a nursery gardening, cutting or in a certain proportion mixed cultivation substrate, the better. Vermiculite low bulk density, can provide a certain amount of potassium and small amounts of calcium, magnesium and other nutrients. Horticulture golf course turf, seed preservative, soil conditioners, humectants, plant growth, feed additives other areas: sorbent, filter aid, chemicals and fertilizers active carrier, sewage treatment, water oil adsorption. Different sizes of vermiculite application 20 Head: Housing insulation equipment, household refrigerator, car muffler, sound stucco, safes and vaults lined pipes, boiler protective clothing, ironworks ladles, insulating firebrick cement 20 -40 mesh: Auto insulation equipment, aircraft insulation equipment, cold storage insulation equipment, bus insulation equipment, wallboard water cooling tower, steel annealing, fire extinguishers, filters, refrigerator 40-120 Head: linoleum, shingles, eaves board, referred gates plate 120-270 Head: burnt wallpaper print, outdoor advertising, paint, increasing the viscosity of paint, photography soft wood with fire cardstock 270 Head: gold and bronze ink, paint outside supplements in addition vermiculite also friction material for brakes, the tunnel fire paint for vermiculite, warm baby with vermiculite insulation, aggregate food additives, pesticide carrier superfine vermiculite, new water treatment materials dedicated vermiculite, animals with a special vermiculite insulation hatch Kelly et vermiculite into: 1-3mm, 2-4mm, 3-7mm, 4-8mm, 20-40 mesh, 40-70 mesh, and vermiculite, silvery white vermiculite, white vermiculite, golden vermiculite vermiculite.
