What is sodium silicate powder? The molecular formula ofsodium silicateis Na2O. nSiO2•xH2O. The properties of sodium silicate vary with the ratio of molecules of silicon dioxide to sodium oxide. This ratio is called the modulus. When the modulus is greater than 3, it is called neutral water glass. When the modulus is less than 3, it is called basic sodium silicate. Sodium silicate has solid and liquid shape, commodity is more common. The shape of liquid sodium silicate is colorless, slightly gray, slightly red transparent or translucent viscous liquid; It is soluble in water. Sodium silicate aqueous solution has viscosity, especially high modulus of high viscosity. When it meets the acid it breaks down and precipitates into a colloidal precipitate of silicic acid. Solid water glass is a kind of sky blue or yellowish-green glassy substance whose relative density increases with decreasing modulus. When the modulus decreases from 3.33 to 1, the relative density increases from 2.413 to 2.560. There is no fixed melting point. Can be used as concrete accelerator and water repellent.
Use of sodium silicate 1. Sodium silicate is a valuable filler in the soap industry. Adding sodium silicate into laundry soap can buffer the alkalinity of laundry soap, reduce the loss of laundry soap in water, enhance the washing ability, and prevent soap from rancidity 2. Sodium silicate plays a role in helping to wash, preventing corrosion, and stabilizing foam in synthetic detergent 3. It can be used as filler for paper making 4. Used to manufacture silicon gel, silica gel 5. It is used as a binder in the foundry industry, bonding sand and clay and making various molds and cores for adults.
Physical and chemical properties of sodium silicate The ratio of silica sand and alkali, i.e., the molar ratio of SiO2 and Na2O, determines the modulus of sodium silicate, n, which shows the composition of sodium silicate. The modulus is an important parameter of sodium silicate, generally between 1.5 and 3.5. The larger the modulus, the more difficult the solid sodium silicate is to dissolve in water, and when n is 1, it can be dissolved in warm water. When n is increased, it can be dissolved in hot water. When the chemical book exceeds 3, it can be dissolved in steam at more than 4 atmospheric pressure. The greater the modulus of sodium silicate, the more silicon oxide content, The viscosity of sodium silicate increases, it is easy to decompose and harden, and the adhesive force increases. Therefore, sodium silicate with different modulus has different uses. It is widely used in many fields, such as ordinary casting, precision casting, paper making, ceramics, clay, mineral processing, kaolin, washing, etc.
