Quartz sand is quartz particles formed by crushing and processing quartz stone. Quartz stone is a non-metallic mineral, which is a hard, wear-resistant and chemically stable silicate mineral. The color of quartz sand is milky white, or colorless translucent, Mohs hardness 7.
Quartz sand is an important industrial mineral raw material, non-chemical dangerous goods, widely used in glass, casting, ceramics and fireproof materials, smelting ferrosilicon, metallurgical flux, metallurgy, construction, chemical industry, plastics, rubber, abrasives, filter media and other industries.
Glass industry Glass plate glass, float glass, glass products (glass jars, glass bottles, glass tubes, etc.), optical glass, glass fiber, glass instruments, conductive glass, glass cloth and special anti-ray glass and other raw materials.
ceramic
Ceramic and refractory porcelain embryo and glaze, kiln for high silicon bricks, ordinary silicon bricks and silicon carbide raw materials; Metallurgical silicon metal, ferrosilicon alloy and silicon aluminum alloy and other raw materials or additives flux concrete, cementing materials, road construction materials, artificial marble, cement physical properties test materials (i.e., cement standard sand).
Water treatment filter material
Because the particle size of the quartz sand of the three-layer filter material filter bed is smaller than that of the quartz sand of the double-layer filter material, and there is a layer of thinner heavy anthracite filter material under the quartz sand layer, the water quality of the filtered water of the three-layer filter material filter is better than that of the double-layer filter material filter under the same other conditions, and even the filter speed is higher. When using quartz sand, try to cooperate with it.
Chemical engineering
Main raw materials, abrasive materials, sand cleaning, rust removal, removal of oxide processing electronic high-purity metal silicon, communication optical 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, container, ship, repair, bridge, mine, 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 a heavy concrete and blast furnace refractory material addition Agent to increase its wear resistance, high temperature resistance, erosion resistance, electrostatic shielding, radiation protection, oil well filter tank, counterweight and so on.
