Shelf silica food grade, industrial grade silica

Chemical formula SiO2 molecular weight: 60.08 Chinese name: Silica Chinese Alias: silicone, silica, silica, silicic anhydride, quartz sand Synonyms: Silicon dioxide SiO, Silicon (IV) oxide, Silicic anhydride, Quartz sand CAS Number:? 7631 -86-9 known as silica. It is widely distributed in nature, such as quartz, quartz sand. White or colorless particles, high iron content is pale yellow. The density of 2.2 to 2.66 melting point 1670 ℃ (tridymite); 1710 ℃ (cristobalite). Boiling point 2230 ℃, the relative dielectric constant of 3.9. Can play a role when the molten alkali insoluble in water slightly soluble in acid, in particulate state. Used in making glass, water glass, pottery, ceramics, refractories, ferrosilicon, sand, elemental silicon. The main raw flat glass, float glass, glass products (glass jars, glass bottles, glass, etc.), optical glass, glass fibers, glass equipment, conductive glass, glass cloth and anti-rays specialty glass and the like. Ceramics and refractory materials billet and glaze porcelain, with a high silica brick kiln, ordinary brick and silicon carbide and the like. Metallurgical silicon metal, silicon and silicon alloy aluminum and other raw materials or additives, flux. Construction concrete, cementitious material, road building materials, artificial marble, cement physical properties of test materials (ie cement standard sand), etc. Chemical silicon compound and water glass and other raw materials, sulfuric acid tower filler, amorphous silica can be used as an adsorbent. The main raw material mechanical foundry sand, abrasive material (sand, hard abrasive paper, sandpaper, emery cloth, etc.). Electronic high-purity silicon metal, optical fiber communication. Rubber & Plastics addition of silica in rubber, can improve the abrasion resistance of the rubber. Can reduce tire rolling resistance while improving the wear resistance of the tire and wet skid resistance. Silica gel material tensile strength, tear strength, abrasion resistance, etc. are improved. Coating the filler (the paint can be improved weatherability), can be used to produce the matting agent, the coating can also be used as a thickener. Food, medicine mainly used in the food industry to prevent caking powdered food gathering, in order to maintain a free flow of food additives or for the adsorption of liquid spices, oils, vitamins, etc., making powder, such as powdered fat, solid perfumes and solid wine like the products. (Example: milk) in the production of drugs can be used as a flow aid, a catalyst carrier. 1, medicinal Silica: mainly used as lubricants, anti-adherents, glidants 2, food and beverage with silica: flow aids, anti-caking properties. 3, rubber silica: eliminate tension, stratification and cracking 4, paint, coating with silica: rheology control, anti-light, anti-sagging, anti-UV, anti-settling and improve corrosion resistance. 5, paper silica: ink-speed, high whiteness, the printed image is clear, bright. 6, mold silica: excellent dispersion, compatibility, high transparency, high whiteness. 7, also produce other silica used in the oil, edible oil bleaching agents, toothpaste abrasive, special leather matting agent.
