Zinc fluosilicate Properties colorless hexagonal prismatic crystals or white hexagonal crystalline powder. The relative density of 2.104. Soluble in water, soluble inorganic acid, insoluble in ethanol. Decomposition of silicon tetrafluoride, water and zinc fluoride when heated to 100 ℃. Its pH 1% aqueous solution is 3.2. Zinc fluosilicate technical implementation of the standard detection index test results (%) ZnSiF6 · 6H2O ≥98 ≤0.6 water insoluble sulfate (SO4) ≤ 0.5 chloride (Cl) ≤ 0.6 iron (Fe) ≤ 0.2 Moisture (H2O) ≤ 0.6 zinc fluosilicate main uses for rapid hardening of concrete agent, treatment agent, mothproofing agents and wood preservatives, plaster enhancer, the catalyst was washed with polyester fibers, is also used to configure the electrolytic bath of zinc and the like. Production methods of fluoride and zinc silicate law: fluorine acid solution was prepared by the reaction of sulfuric acid, fluorite and silica sand, and then lead salts (fluoro-silicate lead or lead carbonate) for purification to remove sulfate. Then zinc oxide and, after filtration, evaporated (to saturated solution), cooling crystallization, centrifugation, and dried to obtain zinc fluosilicate finished. Fluorine zinc silicate outer packaging and transportation white woven bag, 50KG bag. It should be stored in a dry warehouse. Prevent moisture. Note that when gently handling, packaging to prevent breakage.
