Quartz sand is a hard, wear-resisting, stable chemical properties of silicate minerals, the main mineral composition is SiO2, quartz sand of milky white or colorless translucent color and hardness of 7, sexual brittle cleavage, conchoidal fracture, oily luster, relative density 2.65, chemical, thermal and mechanical properties has obvious anisotropy, insoluble in acid, slightly soluble in KOH solution, melting point 1750 ºC. Color white, weak yellow, brown and gray, quartz have higher fireproof performance.
Quartz sand have unique physical and chemical properties, make its in aviation, aerospace, electronic, mechanical, and today a significant role in the rapid development of IT industry, especially its internal molecular chain structure, the change law of crystal shape and crystal lattice, make its have the high temperature resistant, small thermal expansion coefficient, high insulation, corrosion resistance, piezoelectric effect and resonance effect and its unique optical properties, in many high-tech products plays an increasingly important role.
Purpose: to make glass, refractories, smelting ferrosilicon, metallurgical flux, ceramic and grinding materials, casting, quartz in the building to use its strong acidic medium erosion resistance, used for making acid and acid-resistant cement mortar. Quartz sand as raw materials for the silicon core raw material in the production and supply of silicon raw material is an important basic role. The applications of Air filter cartridge Air filter cartridge is used in petroleum, water, air, oil field, refinery, medicine equipment, pipeline filters, railroad, astronautics, project machinery, etc.
