Shiling town quartz sand quartz sand Chini town Tanbu yayao town quartz sand quartz sand high purity quartz sand: SiO2≥99.9-99.99% Fe2O3≤0.001%, is made from natural stone or crystal quality natural silica, carefully selected, fine processing. Contents 1 Physical and chemical properties of two, using three, four main origin, production processes five refining quartz sand grading standards a, physical and chemical properties edit high-purity quartz sand: SiO2≥99.9-99.99% Fe2O3≤0.001%, is the use of natural crystal stone or high-quality natural silica, carefully selected, fine processing. Particle size range of 0.3-0.1mm, 0.1-0.01mm, 0.01-0.005mm, but also according to user requirements. Two high-purity quartz sand, high purity quartz sand editor application has unique physical and chemical properties, so that it occupies a pivotal in aviation, aerospace, electronics, machinery, and today's rapid development of IT industry in the position, especially its intrinsic molecular structure, crystal shape and lattice variation of the chain, it has a high temperature, thermal expansion coefficient is small, highly insulated, corrosion resistance, piezoelectric effect, resonance effect and its unique optical properties, in many high-tech products play a more an increasingly important role. Specific applications are as follows: First, the 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-rays and other specialty glass raw billet and glaze porcelain, with a high silica brick kiln, ordinary brick and silicon carbide, etc.: two main raw materials, ceramics and refractories. Metallurgy: silicon metal, silicon and silicon alloy aluminum and other raw materials or additives, flux three buildings: concrete, cementitious material, road building materials, artificial marble, cement physical properties of test materials (ie cement standard sand), etc. Fourth, chemical : silicon compounds and water glass and other raw materials, sulfuric acid tower filler, amorphous silicon dioxide Five, mechanical: the main raw material for foundry sand, abrasive material (sand, hard abrasive paper, sandpaper, emery cloth, etc.) Six, electronic : high-purity silicon metal, communication with the fiber, seven, rubber, plastics: fillers (can improve the wear resistance) VIII Coatings: fillers (coatings can improve weather resistance) 9, the metallurgical industry: silicon metal, silicon and silicon aluminum alloy alloys and other raw materials or additives, flux ten, aviation, aerospace: its internal structure, crystal shape and lattice variation of the molecular chain, it has a high temperature, thermal expansion coefficient is small, highly insulated, corrosion resistance, piezoelectric effect, resonance effect and its unique optical properties. 3 Third, the main origin of the editors from the country concerned, Donghai County, Jiangsu Province is the main producing areas of quartz raw materials accounted for 80% of the national market. Its raw materials with high purity and yield nationally known. 4 Fourth, the production process of a production process editor, mineral: ore sorting finishing second, washing: wash with the naked eye no impurities prevail Third, calcination: Set the oven 860 degrees Celsius, with red stone when the material subject Fourth, water quenching: cooling water quenching, to loose structure V. smash: crushed by a jaw crusher, then pulverized by a roll mill six screening: Perform a visual classification number seven, cleaning: After several high-purity clear-eight Drain : nine by centrifuge dewatering, drying process: ten into the oven drying, magnetic separation: Go magnetic separator to remove iron impurities were eleven, into the flotation machine selection again twelve, after manual inspection, packaging warehousing five refining quartz sand grading edit no less than% level names silica impurities not more than ppm burning vector no more than% ferric oxide titanium and aluminum lithium, sodium and potassium 1 ultra-pure quartz sand 99.98 2.0 0.5 30 2.0 3.0 3.0 3.0 0.1 2 high-purity quartz sand 3 99.98 4.0 0.5 70 3.0 20 1.0 99.95 flotation of quartz optical hydrochloric acid quartz sand 5.0 4 99.6 50 2.0 300
