Introduction of use of quartz sand:
The unique physical and chemical properties of quartz sand, which plays an important role in aviation, aerospace, electronics, machinery and the rapid development of the IT industry, especially its intrinsic molecular chain structure, crystal shape and lattice changes, make its temperature resistance, low thermal expansion coefficient, high insulation corrosion resistance, piezoelectric effect, resonant effects and its unique optical properties, plays an increasingly important role in many high-tech products. Fine quartz sand can be used as abrasive for grinding glass and so on.
First, glass: flat glass, float glass, glass product (glass tank, glass bottle, glass tube, etc.), optical glass, glass fiber, glass instrument, conductive glass, glass cloth and special raw materials for radiation protection special glass.
Two, ceramic and refractory materials: embryo material and porcelain glaze, kiln with high silica, silica and silicon carbide and other raw materials.
Three, metallurgy: silicon metal, ferrosilicon alloy and silicon aluminum alloy, such as raw materials or additives, flux.
Four, construction: concrete, cementitious materials, road building materials, artificial marble, cement physical performance testing materials (that is, cement standard sand) and so on.
Five, chemical industry: the raw material of silicon compound and water glass, the filler of the sulphuric acid tower, and the amorphous silica powder.
Six: the main raw material, machinery casting sand, grinding materials (sand, hard abrasive paper, sandpaper, emery cloth, etc.).
Seven, electronic: high purity metal silicon, communication optical fiber and so on.
Eight, rubber, plastic: packing (can improve the wear resistance).
