Quartz sand Its unique physical and chemical characteristics make it occupy a pivotal position in aviation, aerospace, electronics, machinery and today's rapidly developing IT industry, especially its internal molecular chain structure, crystal shape and lattice change law, which make it have high temperature resistance, small thermal expansion coefficient, high insulation, corrosion resistance, piezoelectric effect Resonance effect and its unique optical characteristics are playing an increasingly important role in many high-tech products.
Purpose:
manufacture Glass , refractory, smelting ferrosilicon, metallurgical flux, ceramics , abrasive material, casting Quartz products can be used in buildings to produce acid resistant concrete and acid resistant concrete mortar 。 As the core raw material of silicon raw material, quartz sand plays an irreplaceable and important role in the production and supply of silicon raw material.
Application field:
Glass plate glass, float glass, glass products (glass jars, glass bottles, glass tubes, etc Raw materials or additives such as ferrosilicon alloy and silicon aluminum alloy, flux building concrete, cementitious materials, road building materials, artificial marble, cement physical property testing materials (i.e. cement standard sand) and other raw materials such as chemical silicon compounds and water glass, fillers for sulfuric acid towers, and main raw materials for amorphous silica micro powder mechanical casting molding sand, Abrasive materials (sand blasting, hard abrasive paper, abrasive paper, abrasive cloth, etc Sand cleaning, rust removal, strengthening, forming, stress relief, surface cleaning and coating of various profiles, roughness (roughening) pretreatment before electroplating, stone cutting, magnetic shot casting, as additives for heavy concrete and blast furnace refractory materials, to increase their wear resistance, high temperature resistance, erosion resistance, electrostatic shielding, radiation prevention The surface treatment of granite and marble, such as filter tank and counterweight of oil well, uses high-quality quartz sand as raw material. The lawn products specially designed and produced for sports venues have the characteristics of high hardness, large ratio, uniform particle size, small edges and corners, natural color, etc. They have little damage to the artificial lawn, form the role of protecting grass wool, and make the lawn more durable. It has been applied in stadiums and gymnasiums of many colleges and universities in China. Quartz sand is an ideal material for supporting the use of modern track and field fields, football fields, golf courses and other artificial fields.
