Sodium silicate (Na2SiO3) is also called sodium silicate and sodium silicate (xNa2O. YSiO2), colorless, turquoise or brown solid or viscous liquid. Sodium silicate is made by melting silica (quartz sand) and soda ash (or soda ash) in a melting furnace, cooling and pulverizing, and its fuel can be medium, natural gas or gas. The production technology of sodium silicate can be divided into dry method and wet method. Solid sodium silicate is usually produced by dry method, and then it is dissolved and converted into liquid sodium silicate with required specifications, and its conversion rate is 1∶2. 5。 The raw materials for producing sodium silicate are quartz sand and soda ash, which are mixed according to a certain proportion, sent to a reflection kiln, quenched in water in a high-temperature calcination melting furnace and packaged to obtain solid sodium silicate. Solid sodium silicate is beneficial to transportation and storage. Dissolving solid sodium silicate into liquid at a certain temperature and pressure is liquid sodium silicate.
