Product Description
Quartz is a hard, wear-resistant, chemically stable silicate mineral, its main mineral composition is SiO2, quartz color is milky white, or colorless translucent, hardness 7, brittle no cleavage, shell fracture, grease luster, density of 2.65, bulk density (1-20 mesh is 1.6, 20-200 mesh is 1.5). Its chemical, thermal and mechanical properties have obvious anisotropy, insoluble in acid, slightly soluble in KOH solution, melting point 1750℃. The quartz luster is glassy and sometimes fatty. Pure texture is colorless; Impurities are red, yellow, blue, black, brown, purple, green; Transparent to opaque, brittle. The fracture is crusty or jagged. The crystal is hexagonal columnar, columnar surface with transverse grain. There is a difference between left and right crystals. Twin crystals are common. It is usually crystalline clusters or granular or blocky aggregates.

Application
Quartz sand as the main raw material, abrasive materials (sandblasting, hard abrasive paper, sandpaper, emery cloth, etc.), sand cleaning, rust removal, removal of oxide skin treatment of electronic high-purity metal silicon, communication fiber and other
rubber, plastic fillers (can improve wear resistance). The coating filler can improve the weatherability of the coating.
The second is: used in casting, forging, machinery, metallurgy, heat treatment, steel structure, grid structure, containers,
ships, repairs, Bridges, mines, and other fields of sand, rust, strengthening, forming, stress relief and surface cleaning and
painting of various profiles, roughness (hair) pretreatment before electroplating, stone cutting, magnetic ball casting.

As an additive to heavy concrete and blast furnace refractory materials, to increase its wear resistance, high temperature
resistance, anti-erosion, electrostatic shielding, radiation protection, oil well filter tank, counterweight and so on.
Quartz sand as raw materials for sports venues design and production of lawn products, with high hardness, large ratio, uniform particle size, small corners, natural color and other characteristics, artificial turf damage is small, the formation of the
protection of grass hair, make the lawn more durable. It has been used in sports venues of many colleges and universities, and
quartz sand is the ideal material for artificial venues such as modern track and field, football field and golf course.
