Quartz sand is the quartz writing processing of silica particles. Also known as silica, Quartz, Quartz stone) is a texture hard, wear-resisting, stable chemical properties of silicate minerals, in nature exist in Quartz sandstone, quartzite and vein Quartz. Production process: from quartz ore crushing - water - screening to pickling, drying and secondary screening
Quartz sand is a kind of more traditional natural abrasive, are widely used in many fields, such as sand blasting, floor and wastewater treatment. Quartz sand abrasive is a kind of non-metallic minerals, is a hard, wear-resisting, stable chemical properties of silicate minerals, the main mineral composition is SiO2, the color of quartz sand is milky white, translucent and transparent, mohs hardness 7, quartz sand is important industrial mineral raw materials, non hazardous chemicals, widely used in glass.
Quartz sand have higher fireproof performance, admiral industrial quartz sand is often divided into: ordinary quartz sand, fine quartz sand, high purity quartz sand, fused quartz and silicon powder, etc.
1, ordinary quartz sand; SiO2 90-99% Fe2O3 0.06 or less - 0.02% or higher, refractoriness 1750 ℃, the exterior part of the larger particles, the surface has a yellow skin cyst. Particle size range 5-220 mesh, grain production according to user requirement. Main application: metallurgy, silicon carbide, glass and glassware, enamel, cast steel, water filtration, paohuajian, chemical industry, spray noisy and other industries.
2, the refined quartz sand; SiO2 99-99.5% Fe2O3 0.02 or less - 0.015% or higher, select high-quality complex ore processing. 5-480 mesh size range, can be produced according to the requirements of customers, appearance white or crystal. Main use: senior glass, glass products, refractories, smelting stone, precision casting, grinding wheel grinding materials, etc.
3, high purity quartz sand; SiO2 acuity 99.5-99.9% Fe2O3 0.005% or less, is to use level 1-3 natural crystal and high quality natural stone, carefully selected, 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, can be produced according to the requirements of customers. In millimeter (mm)
4, fused quartz sand; Chemical composition: SiO2 99.9 99.95%; Appearance is colorless transparent block, granular or white powder. Relative density: 2.21; Mohs hardness: 7.0; PH: 6.0;
5, silicon powder; Appearance is gray or gray powder, refractoriness > 1600 ℃. Density: 200 ~ 250 kg/m3.
6, color quartz sand; Main raw material is quartz sand, through the industrial fuel processing, became the dye color sand.
Quartz sand inner molecular chain structure, crystal shape and crystal lattice change rule, has the high temperature resistance, small thermal expansion coefficient, high insulation, corrosion resistance, piezoelectric effect and resonance effect, and its unique optical properties, in many high-tech products plays an increasingly important role.
Quartz sand is important industrial mineral raw material, the hazardous chemicals, widely used in glass, casting, ceramics and refractories, smelting ferrosilicon, metallurgical flux, metallurgy, construction, chemical, plastic, rubber, abrasive and other industries.
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 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 abrasion resistance)
9, coating, packing (acid can improve the coating)
10, 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.
11. The color sand can be used in all kinds of color epoxy floor paint, really stone paint, all kinds of architectural coatings, sandstone plate, ABS modified linoleum, waterproofing materials, arts and crafts, etc.
