Характеристики

The unique physical and chemical properties of quartz sand is, in the aviation, aerospace, electronics, machinery and plays a very important role in today's rapid development of IT industry, especially the internal structure of molecular chain, shape variation and crystal lattice, which has high temperature resistance, low thermal expansion coefficient, high insulation, corrosion resistance, piezoelectric effect, resonant effects and its unique optical properties, plays an increasingly important role in many high-tech products.

Quartz sand is an important industrial mineral raw material, non hazardous chemicals, widely used in glass, casting, ceramics and refractories, smelting ferrosilicon, metallurgical flux, metallurgy, construction, chemical, plastic, rubber, abrasive and other industries. The motor, train transportation, water transportation. Industrial production is generally 50KG or 25KG packaging and export tons packaging specifications: 0.5-1.0mm 0.6-1.2mm. 1-2mm 2-4mm 4-8mm 8-16mm 16-32mm. (mm mm units) ordinary quartz sand.

One, glass: flat glass, float glass, glass products (glass bottles, glass bottles, glass tubes, etc.), optical glass, glass fiber, glass equipment, conductive glass, glass cloth and anti ray special glass, such as the main raw materials.

Two, ceramic and refractory materials: embryo material and porcelain glaze, kiln with high silica brick, ordinary raw materials such as silicon carbide.

Three, metallurgical silicon metal, ferrosilicon alloy and silicon Aluminum Alloy and other raw materials or additives, flux

Four, construction: concrete, cementitious materials, construction materials, artificial marble, test material physical properties of cement (cement standard sand).

Five, chemical: silicon compounds and water glass and other raw materials, sulfuric acid tower filler, amorphous silica powder

Six: the main raw material, machinery casting sand, grinding materials (sand, hard abrasive paper, sandpaper, emery cloth, etc.)

Seven, electronics: high purity metal silicon, communication with optical fiber, etc.

Eight, rubber, plastic: filler (can improve wear resistance)

Nine, paint: filler (can improve the acid resistance of paint)

Ten, aviation, aerospace.
