High quality quartz sand products from natural quartz sandstone mines, is a natural quartz ore after crushing, selected after 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 materials, non hazardous chemicals, widely used in glass, foundry, ceramic and refractory materials, smelting ferrosilicon, metallurgical flux, metallurgy, construction, chemical, plastic, rubber, abrasive and other industries.It is processed by complex physical processes and contains more than 99% silica.Its ultra-high silicon content determines its hardness. Due to this characteristic, quartz sand is also used in the construction industry. In recent years, quartz sand is also used in high-end aviation industry and electronic industry.With the continuous development of fine processing of quartz sand equipment, it is believed that quartz sand products will enter more and more high-end industries in the future and realize the value of quartz sand itself.
I. application of quartz sand in glass: main raw materials of plate glass, float glass, glass products (glass cans, glass bottles, glass tubes, etc.), optical glass, glass fiber, glass instruments, conductive glass, glass cloth and special ray proof glass.
Ceramics and refractory materials cannot be separated from quartz sand and quartz powder series products: the blank and glaze of porcelain, raw materials of high silicon brick, ordinary silicon brick and silicon carbide for kiln.
Iii. Metallurgy: raw materials or additives and fluxes for silica metal, ferrosilicon alloy and si-al alloy made by quartz sand
Four, construction: the most commonly used concrete, cementitious materials, road materials, artificial marble, cement physical performance test materials (cement standard sand)
Chemical industry: raw materials of silicon compounds and sodium silicate, fillers for sulfuric acid towers, amorphous silica powder
Machinery: main raw materials for foundry sand, grinding materials (sandblasting, hard abrasive paper, sandpaper, emery cloth, etc.)
Ix. Coating: filler (can improve the acid resistance of coating)
X. aviation and aerospace: its internal molecular chain structure, crystal shape and lattice change rules enable it to have high temperature resistance and thermal expansion.
