Quartz sand

详情

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, white crystals, multi type globular 7 hardness, brittle no cleavage, conchoidal fracture, oily luster, density 2.*5, bulk density (***0 mesh is 1.6), *****0 mesh is 1.5, the chemical, thermal and mechanical properties has obvious anisotropy, insoluble in acid, slightly soluble in KOH solution, melting point ***0 ℃.Without impurities, high mechanical strength, stable chemical performance, large carrying capacity, long cycle life, good economic benefit.

Quartz sand physical and chemical indicators


 

Quartz sand purpose
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 of the embryo and the glaze, kiln with high silica silica brick, and silicon carbide materials.
3, metallurgy: silicon metal, ferrosilicon and silicon aluminum alloy raw materials or additives, flux.
4, building: concrete, cementing materials, construction materials, artificial marble, cement physical property test material (i.e., cement standard sand), etc.
5, chemicals: silicon compound and sodium silicate materials, such as sulfuric acid tower padding, the amorphous silica powder.
6, machinery, foundry sand, the main raw materials, grinding materials (sand, hard and 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 wear resistance).
9, coating, packing (acid can improve the coating).
*0, aviation, spaceflight, its molecular chain structure, crystal shape and crystal lattice change rule, make its have the high temperature resistant, small thermal expansion coefficient, high insulation, corrosion resistance, piezoelectric effect, resonance effect, and its unique optical properties.
