Sandblasting quartz sand

Quartz sand is quartz particles made by crushing quartz stone. Quartz stone is a non-metallic mineral. It is a hard, wear-resistant and chemically stable silicate mineral. Its main mineral component is SiO₂. The color of quartz sand is milky white, colorless, and translucent, and the Mohs hardness is 7. It is widely used in glass, casting, ceramics and fireproof materials, smelting ferrosilicon, metallurgical flux, metallurgy, construction, chemical industry, plastics, rubber, abrasives, filter materials, and other industries.

Physical and chemical analysis of quartz sand:

Main categories:

Quartz has high refractory performance. In industry, quartz sand is usually divided into: ordinary quartz sand, high-purity quartz sand, fused silica sand, and silicon micro powder.

Quartz has high refractory properties. In industry, quartz sand is usually divided: ordinary quartz sand, high-purity quartz sand, fused silica sand, and silicon micro powder.

1. Common quartz sand: 

It is a water treatment filter material made from natural quartz ore after crushing, washing, drying and secondary screening; the filter material has no impurities, no edges and corners, it has high density, high mechanical strength, and no pollution. Capacity lines have a long service life and are ideal for chemical water treatment. 

Main applications:

metallurgy, ink silicon carbide, glass enamel sodium hydroxide, chemical industry, noise spray, and other industries.

2. Refined quartz sand: 

(1) It is also known as pickled quartz sand

(2) SiO₂≥99-99.5%

(3) Fe₂O₃≤0.005%

(4) Using high-quality natural quartz sand and mortar.

3. High-purity quartz sand: 

(1) SiO₂≥99.5—99.9%

(2) Fe₂O₃≤0.001%,

(3) Using high-quality natural quartz stone and mortar.

Application fields: 

Quartz sand is an important industrial mineral raw material, non-chemical dangerous goods, widely used in glass, casting, ceramics and refractory materials, smelting ferrosilicon, metallurgical flux, metallurgy, construction, chemical industry, plastics, rubber, abrasives and other industries.

1. Glass: the main raw material of flat glass, float glass, glass products (glass jars, bottles, glass tubes, etc.), optical glass fiberglass, glass instruments, conductive glass cloth, and special radiation-proof glass.

2. Ceramics and refractory materials: blanks and glazes for porcelain, raw materials for high-silica bricks for kilns, ordinary silica bricks, and silicon carbide.

3. Metallurgy: raw materials or additives, fluxes for silicon metal, ferrosilicon alloy and silicon aluminum alloy, etc.

4. Construction: concrete, cementitious materials, road construction materials, artificial marble, cement physical performance test materials (ie cement standard sand), etc.

5. Chemical industry: raw materials for silicon compounds and water glass, fillers for sulfuric acid towers, amorphous silica powder

6. Machinery: the main raw material of foundry sand, abrasive materials (sandblasting, hard abrasive paper, sandpaper, emery cloth, etc.)

7. Electronics: high-purity metal silicon, optical fiber for communication, etc.

8. Rubber and plastic: filler (improve wear resistance)

9. Coating: filler (can improve the acid resistance of the coating)

10. Aviation and aerospace.
