Quartz sand is quartz stone crushing processing of quartz grains, quartz stone is a kind of non-metallic minerals, is a hard, wear-resisting, stable chemical property of silicate minerals, the main mineral composition is SiO2 and quartz sand color is milky white, or colorless translucent, Mohs hardness of 7, quartz sand is an important industrial mineral raw material, non hazardous chemicals, widely used in glass, casting, ceramics and refractory, smelting, flux for metallurgy, metallurgy, construction, chemical, plastics, rubber, grinding, filtering material, etc., industrial.
Quartz sand commonly used specifications are: 0.5-1mm, 1-2mm, 2-4mm, 4-8mm, 8-16mm, 16-32mm, 10-20 mesh, 20-40 mesh, 40-80 mesh, 80-120 mesh, 100-200 mesh, 200 mesh, 325 mesh.
♦ Building concrete, cementitious materials, road materials, artificial marble, cement physical performance test materials (cement standard sand).
♦ Glass flat glass, float glass, glass (glass jar, glass bottle, glass tube, etc.), optical glass, glass fiber, glass instrument, conductive glass, glass cloth and anti ray special glass as the main raw material.
♦ Ceramic and refractory materials embryo material and porcelain glaze, kiln with high silica, silica and silicon carbide and other raw materials.
♦ Metallurgical silicon metal, ferrosilicon alloy and silicon Aluminum Alloy and other raw materials or additives, flux.
♦ Chemical silicon compounds and water glass and other raw materials, sulfuric acid tower filler, amorphous silica powder.
♦ Machinery casting sand, the main raw material, grinding materials (sandblasting, hard abrasive paper, sandpaper, emery cloth, etc.), sand cleaning, derusting, removal of oxide skin.
Transport and handling: in the transport process, not drag hook, should prevent mixed with the solid material, strong vibration, friction, hit, hit, forbid throwing should be lightly armed light discharge, to reduce the breakage of packing, the impact of the use.
Storage: should be stored in a cool and dry place, to prevent internal and external packaging bag break, prevent moisture and adsorption of other substances in the air, affect the use effect. It is strictly prohibited to mix with poisonous and harmful gas or volatile matter, and keep away from the source of pollution.
