The main classification of quartz sand quartz has a higher fire resistance, quartz sand industry will often be divided into: ordinary quartz sand, quartz sand refined, high-purity quartz sand, fused silica sand and microsilica. Ordinary quartz sand ordinary quartz sand, which SiO2≥90-99% Fe2O3≤0.06-0.02%, refractoriness 1750 ℃, the appearance of some large particles, the surface of yellow cysts. Size range 5-220, user requirements particle production. Main purpose: metallurgy, Mexico silicon carbide, glass and glass products, ceramic, steel, water filtration, sodium silicate, chemical pickling quartz sand, spraying noisy industries. Refining quartz sand, also known as pickling quartz sand, SiO2≥99-99.5% Fe2O3≤0.005%, using high-quality natural quartz sand, carefully selected, fine fine quartz sand processing. Size range 1-0.5mm, 0.5-0.1mm, 0.1-0.01mm, 0.01-0.005mm, according to user requirements. Uses: manufacture of glass, refractories, smelting ferrosilicon, metallurgical flux, ceramics, abrasive materials, quartz sand casting molding, etc., in the building with its strong acid etching medium capacity for extracting acid and acid of concrete mortar . Refining quartz sand SiO2≥99-99.5% Fe2O3≤0.02-0.015% quartz sand, featuring high-quality ore processing complex. With 5-480 mesh size range, according to user requirements, the appearance of white or crystals. Main purpose: Senior glass and glass products, refractories, smelting stone, precision casting, grinding wheel and other materials. (Mm is millimeters) a glass: flat glass, float glass, glass products (glass jars, glass bottles, glass, etc.), optical glass, glass fibers, glass equipment, conductive glass, glass cloth and anti-ray special glass etc. The main raw material. Raw billet and glaze porcelain, with a high silica brick kiln, ordinary brick and silicon carbide, etc.: Second, ceramics and refractories. Third, Metallurgy: silicon metal, silicon and silicon alloy aluminum and other raw materials or additives, flux four buildings: concrete, cementitious material, road building materials, artificial marble, cement physical properties of test materials (ie cement standard sand), five CHEMICAL: silicon compounds and water glass and other raw materials, sulfuric acid tower filler Buying quartz sand, amorphous silica dioxide Six machinery: the main raw material for foundry sand, abrasive material (sand, hard abrasive paper, sandpaper, emery cloth etc.) VII electronics: high-purity silicon metal, communication with the other eight fiber, rubber, plastics: fillers (can improve the wear resistance) 9, paint: the filler (which can improve the coating of acid resistance) ten, aviation, space: its intrinsic molecular chain structure, crystal shape and lattice changes, it has a high temperature, thermal expansion coefficient is small, highly insulated, corrosion resistance, piezoelectric effect, resonance effect and its unique optical properties.川柏 Linfen quartz sand _ _ quartz sand provided by the Henan Saatchi Saatchi water purification materials Limited.
