Quartz sand introduction:

Quartz sand is a hard and wear resistant, chemical performance and stability of silicate minerals, its main mineral composition is SiO2, quartz sand color of ivory, or colorless translucent shape, a multi type ball white crystals, hardness and brittleness, sex without cleavage, conchoidal fracture, grease sheen, density of 2.65, bulk density (1 - and mesh is 1.6), twenty - 200 mesh is 1.5, the chemical, thermal and mechanical properties has obvious anisotropy, not soluble in acid, slightly soluble in KOH solution, melting point 1750 ℃.

Quartz sand features: without impurities, high mechanical strength, stable chemical performance, cutting carrying capacity big, use cycle is long, and the economic benefit is good.

Quartz sand is a kind of non-metallic minerals, is a hard and wear resistant, chemical performance and stability of silicate minerals, its main mineral composition is SiO2, quartz sand color of ivory, or colorless translucent shape, hardness 7, quartz sand is an important industrial mineral raw materials, the hazardous chemicals, widely used in glass, casting, ceramic and refractory materials, smelting silicon, metallurgical additive, metallurgy, construction, chemical, plastic, rubber, abrasive, and other industrial and refractory materials, chemical industry, precision casting and electronic industries.

Quartz sand classification:

Quartz have higher fireproof performance, industry of quartz sand are often divided into: ordinary quartz sand, refining quartz sand, high purity quartz sand, fused quartz sand and silicon micro powder, etc.

Ordinary quartz sand, namely SiO2 was 90-99% or less Fe2O3 0.06-0.02%, 1750 ℃, the appearance of refractoriness of large particles, the surface has yellow skin cyst. Particle size range 5-220 mesh, can according to user requirements size production.

Refining quartz sand is also called pickling quartz sand, SiO2 was 99-99.5% 0.005% or less Fe2O3, USES the high quality natural quartz sand, carefully chosen, fine processing and into. Particle size range 1-0.5 mm, 0.5 0.1 mm, 0.1 0.01 mm, 0.01 0.005 mm, according to user requirements processing. Purpose: to make glass, refractory materials, smelting silicon, metallurgical fusing agent, ceramic, grinding materials, casting modelling quartz sand, etc., in the construction of the strong acid medium erosion ability, making acid concrete and acid slurry.

Commonly used specifications: 0.5-1.0 mm to 1.2 mm to 0.6-0.8-1.6 mm 1.0 2.0 mm to 2.0-4.0 mm 4.0 8.0 mm 8.0-16 mm 16-32 mm
