Product name:
Quartz powder, glass, casting, refractory quartz sand. White sand, white sand, even
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 ℃.
Appearance:
A white crystal with a multi-edged ball
Features:
No impurities, high mechanical strength, stable chemical performance, high cutting ability, long period of use, good economic performance.
USES:
Suitable for artificial lawn sand, sandblast and single layer, double layer rapid filter and industrial high purity filter water.
Quartz sand 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, hardness of 7, quartz sand is important industrial mineral raw material, the hazardous chemicals, widely used in glass, foundry, ceramic and refractory materials, smelting ferrosilicon, metallurgical flux, metallurgy, construction, chemical, plastic, rubber, abrasive and other industries.
(1) the combination of mechanical strength, breakage and wear rate should not be greater than 1.5% (percentage by weight). (2) the properties are stable, with no visible soil, mica and organic impurities, and the water leaching of the filtrate is free of toxic and harmful substances. The density of quartz sand should not be less than 2.55 g/cm3. (except for the special requirement for density). (4) it should not be greater than 0.7 percent of the burning weight of quartz sand, and the soluble rate of hydrochloric acid should not be greater than 1.5% (the ministry's standard). (5) the amount of mud should not be greater than 1%, and the amount of light less than 2g/cm3 should not be greater than 0.2% (the ministry's standard). (6) the size of the particle size should be reasonable, and the appearance of a multi-angular monologue. The range of particle size of single or double layer filter is 0.5-1.2 mm. The size of the three-layer filter is 0.5-0.8 mm. (7) the size of the particle size is less than the specified limit and the size of the limit is less than 3%. (8) the range of particle size of the quartz gravel bearing layer is usually 2-4, 4-8, 8-16, 16-32 and 32-64mm.
The packaging and storage of quartz sand: double or single ply woven bags, 50 kg each.
Quartz sand is commonly used in specifications:
0.5-1mm, 1-2mm, 2-4mm, 4-8mm,
8-16 mm, 16-32 mm, 10-20 mm,
20-40 mm, 40-80 mm, 80-120 mm,
100-200 mm, 200 mm, 325?mm
It is mainly used as the raw material of glass industry and ceramics industry, widely used in the metallurgical industry's flux, refractories, chemical industry, precision casting and electronic industry.
Fine quartz sand can be used as abrasive glass, etc.
