Quartz Sand Water Filtration Sand Water Softening System Water Treatment System Sewage Water Treatment
Quartz sand is a quartz particle made by crushing quartz stone. Quartz stone is a non-metallic mineral, a hard, wear-resistant, chemically stable silicate mineral, and its main mineral component is SiO2. The color of quartz sand is milky white, or colorless and translucent, with a Mohs hardness of 7.
Quartz sand is an important industrial mineral raw material, non-chemical dangerous goods, widely used in glass, casting, ceramics and fireproof materials, ferrosilicon smelting, metallurgical flux, metallurgy, construction, chemical industry, plastics, rubber, abrasives, filter materials and other industries.
Quartz sand is a hard, wear-resistant, and chemically stable silicate mineral. Its main mineral component is SiO2. The color of quartz sand is milky white, or colorless and translucent, with a hardness of 7. Shaped fracture, grease luster, density 2.65, bulk density (1.6~1.8 for 1-20 mesh), 1.5 for 20-200 mesh, its chemical, thermal and mechanical properties have obvious anisotropy, insoluble in acid, slightly soluble In KOH solution, the melting point is 1750°C.
Common specifications of quartz sand are: 0.5-1mm, 1-2mm, 2-4mm, 4-8mm, 8-16mm, 16-32mm, 10-20 mesh, 20-40 mesh, 40-80 mesh, 100-120 mesh.
Main category
Quartz has high refractory performance. In industry, quartz sand is usually divided into: ordinary quartz sand, refined quartz sand, high-purity quartz sand, fused silica sand and silica powder, etc.
The unique physical and chemical properties of quartz sand make it occupy a pivotal position in aviation, aerospace, electronics, machinery and today's rapidly developing IT industry, especially its internal molecular chain structure, crystal shape and lattice changes. , so that it has high temperature resistance, small thermal expansion coefficient, high insulation, corrosion resistance, piezoelectric effect, resonance effect and its unique optical characteristics, which play an increasingly important role in many high-tech products.
Quartz sand is an important industrial mineral raw material, non-chemical dangerous goods, widely used in glass, casting, ceramics and refractory materials, ferrosilicon smelting, metallurgical flux, metallurgy, construction, chemical industry, plastics, rubber, abrasives and other industries. It can be transported by car, train and water. Industrial production is generally 50KG or 25KG packaging and export ton bag packaging. Common specifications: 0.5-1.0mm 0.6-1.2mm 1-2mm 2-4mm 4-8mm 8-16mm 16-32mm. (mm is millimeter)
Application
1. Glass: the main raw materials of flat glass, float glass, glass products (glass jars, glass bottles, glass tubes, etc.), optical glass, glass fiber, glass instruments, conductive glass, glass cloth and special radiation-proof glass.
2. Ceramics and refractory materials: blanks and glazes for porcelain, raw materials for high-silica bricks for kilns, ordinary silica bricks, and silicon carbide.
3. Metallurgy: raw materials or additives, fluxes for silicon metal, ferrosilicon alloy and silicon aluminum alloy, etc.
4. Construction: concrete, cementitious materials, road construction materials, artificial marble, cement physical performance test materials (ie cement standard sand), etc.
5. Chemical industry: raw materials such as silicon compounds and water glass, fillers for sulfuric acid towers, amorphous silica powder
6. Machinery: the main raw material of foundry sand, abrasive materials (sandblasting, hard abrasive paper, sandpaper, emery cloth, etc.)
7. Electronics: high-purity metal silicon, optical fiber for communication, etc.
Eight, rubber, plastic: filler (can improve wear resistance)
9. Coating: filler (can improve the acid resistance of the coating)
10. Aviation and aerospace.
