The quartz sand www.gyhltl.com is a hard, wear-resistant, stable chemical properties of silicate minerals, its main mineral composition is SiO2, quartz sand color is white or colorless translucent, hardness 7, brittle no cleavage, conchoidal fracture, oil sheen, the relative density of 2.65, and its chemical, thermal and mechanical properties have obvious anisotropy, insoluble in acid, slightly soluble in KOH solution, the melting point of 1750 ° C. Milky white color, yellow, brown and gray, quartz higher fire resistance is divided into: ordinary quartz sand, quartz sand refined, pickling quartz sand, high purity quartz sand. Unique physical and chemical properties of quartz sand, so that it occupies a pivotal position in the aviation, aerospace, electronics, machinery, as well as today's rapid development of the IT industry, especially its intrinsic molecular chain structure, crystal shape and lattice variation it has a high temperature, thermal expansion coefficient is small, highly insulated, corrosion-resistant, the piezoelectric effect, resonance effects, as well as its unique optical properties, play an increasingly important role in many high-tech products. Uses: manufacture of glass, refractories, smelting ferrosilicon, metallurgical flux, ceramics, abrasives, foundry, quartz in the building to use its strong acid medium erosion ability, used for extracting the the concrete acid and acid-resistant mortar. Quartz sand as a core raw material of silicon feedstock in the production and supply of silicon raw materials played an important foundation of the irreplaceable role. Hualong filter plant quartz sand sales center in Gongyi City, the main business: pickling quartz sand, refined quartz sand, refined pickling quartz sand, pure quartz sand, ordinary quartz sand, quartz sand powder.
