CAS :
traits : liquid, solid and powdered variety of products. Most of the liquid, transparent colorless or light gray with the smears.
purposes : for the oil SiO2/Al2O3 FCC catalyst, soap, and the filler, the adhesive corrugated metal preservatives, water softener, detergent additives, raw materials for ceramics and refractories, textile bleaching, dyeing and pulp, mining beneficiation, waterproof, plugging, wood fire , and food preservation system adhesives, silica, silica sol, zeolite, such as carbon black white.
preparation or sources : production methods are dry and two wet. Dry Soda is (or sodium plus coal) and quartz sand under high temperature melting white, and then cooling, smash, dissolved concentration derived. Wet is liquid caustic soda and quartz sand generated from gaining strength. Wet difficult system high modulus product, but it is simple and easy to get raw materials and low-cost advantages.
Note : containing different from the proportion of sodium oxide and silica formed. Silica Oxide and the molar ratio of sodium said modulus. Modulus is more than three "neutral" water glass, less than three is "basic" water glass. With the physical nature modulus vary.
