Introduction to Quartz Sand
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 of 2.65 g/cm3, 1-20 mesh density of 1.6 g/cm3, 20-200 mesh is 1.5 g/cm3, chemical, thermal and mechanical properties has obvious anisotropy, insoluble in acid, slightly soluble in KOH solution, melting point 1750 ℃.Widely used in glass, foundry, ceramic and refractory materials, smelting ferrosilicon, metallurgical flux, metallurgy, construction, chemical, plastic, rubber, abrasive and other industries.
quartz sand classification
Ordinary quartz sand is made of natural quartz ore, a water filter by crushing, washing, drying, sieving two times into; ordinary quartz sand filter has the filtration function, like water infiltration into the ground through the gravel, water, those suspensions blocked off, mainly for those fine suspended solids. Quartz sand filter with: no impurities, no school angle, high density, high mechanical strength, load interception capability, long service life, is the ideal material for chemical water treatment.
Kojun Shiyingsa main purposes: metallurgy, graphite silicon carbide, glass and glass products, enamel, cast steel, water filtration, paohuajian, chemical, spray and other industries.
Application field of quartz sand
Quartz sand is an important industrial mineral raw material, non hazardous chemicals, widely used in glass, casting, ceramics and refractory, smelting, metallurgy, metallurgy, construction, chemical agent, plastic, rubber, abrasive and other industries.
one, glass: flat glass, float glass, glass (glass jar, glass bottle, glass tube), the main raw material of optical glass, glass fiber, glass equipment, glass, glass cloth and anti ray special glass etc..
Two, ceramic and refractory materials: embryo material and porcelain glaze, kiln with high silica brick, brick and the ordinary raw materials such as silicon carbide.
Three, metallurgy: silicon metal, ferrosilicon alloy and silicon aluminum alloy and other raw materials or additives, flux.
Four, building: concrete, cementitious materials, road test material physical properties of materials, artificial marble, cement (cement standard sand).
Five, chemical: silicon compounds and water glass and other raw materials, sulfuric acid tower filler, amorphous silica powder.
Six, machinery: the main ingredient in sand casting, grinding materials (sand, hard abrasive paper, sandpaper, emery cloth etc.).
Seven: high purity silicon metal, electronic, optical fiber etc..
Eight, rubber, plastics: packing (which can improve the wear resistance).
Nine, coating: packing (can enhance the acid resistance paint).
Ten, aviation, space: the internal structure of molecular chain, crystal shape and lattice changes, make its temperature resistance, with small thermal expansion coefficient, high insulation, corrosion resistance, the piezoelectric effect, the resonance effect and its unique optical properties.
