Quartz sand is the quartz writing processing of quartz grain, quartz is a kind of non-metallic minerals,
is a hard, wear-resisting, stable chemical properties of silicate minerals, the main mineral composition is SiO2, quartz sand color for the milky white or colorless translucent, mohs hardness 7, quartz sand is important industrial mineral raw materials, the hazardous chemicals, widely used in glass, foundry, ceramic and refractory materials, smelting ferrosilicon, metallurgical flux, metallurgy, construction, chemical, plastic, rubber, abrasive, filter material and other industries.
Performance Feature:
Quartz sand is a hard, wear-resisting, stable chemical properties of silicate minerals, the main mineral composition is SiO2, quartz sand color for the milky white or colorless translucent, 7 hardness, brittle no cleavage, conchoidal fracture, oily luster, density 2.65, bulk density (1-20 mesh is 1.6), 20-200 mesh is 1.5, the chemical, thermal and mechanical properties has obvious anisotropy, insoluble in acid, slightly soluble in KOH solution, melting point 1750 ℃.
Ordinary quartz sand is a kind of water treatment filter material; The filter material has: no impurities, no edges, density, mechanical strength, high load carrying capacity line long use cycle characteristics, is the ideal material of chemical water treatment.
Mainly application:
1. Glass, flat glass, float glass, glass products, glass jars, glass bottles, glass, etc.), optical glass, glass fiber, glass instruments, conductive glass, glass cloth and the rays, special glass, etc. The main raw material.
2. Ceramics and refractory materials: porcelain embryo and the glaze, kiln with high silica silica brick, and silicon carbide materials.
3. Metallurgy: silicon metal, ferrosilicon and silicon aluminium alloy raw materials or additives, flux
4. Building: concrete, gelling materials, road construction materials, artificial marble, cement physical property test material (i.e., cement standard sand), etc
5. Chemical industry, silicon compound and sodium silicate materials, such as sulfuric acid tower padding, the amorphous silica powder
6. The main raw material of machinery, foundry sand, abrasive materials (sandblasting, hard abrasive paper, abrasive paper, abrasive cloth, etc.)
7. Electronic: high purity silicon metal, communications with optical fiber, etc
8. Rubber, plastic, packing (can improve the abrasion resistance)
9. Coating: packing (acid can improve the coating)
10. Aviation and aerospace.
