Sodium silicate (water glass): sodium silicate is sodium silicate solution state, the South said more sodium silicate, sodium silicate, said of Northern. Quartz powder usually alkaline sodium silicate (SiO2) plus soda ash (Na2CO3), at a high temperature of 1300 ~ 1400 ℃ calcined to form a solid, redissolved in water at a high temperature or high temperature and pressure, to obtain a solution of water glass-like product. China s production of sodium silicate modulus is generally between 2.4 to 3.3. Water glass content (or concentration) in aqueous solution commonly density or Baume degrees. The density of water glass commonly used in civil engineering is generally 1.36 ~ 1.50g / cm3, equivalent to 38.4 ~ 48.3 degrees Baume. Density, the higher the water glass content, the greater the viscosity.
Sodium silicate in the light of the detergent, soap and other detergents indispensable raw materials, but also the quality of softeners to help Shen agents; to help dye, bleach and sizing in the textile industry; widely used in machinery industry casting, wheel manufacturing and metal preservatives; used in the construction industry in manufacturing hydraulic cement, acid cement waterproof oil, soil stabilizer, refractories; in agriculture can be manufactured Silicon fertilizer; additionally used as silicon oil catalytic cracking aluminum catalyst, soap packing, corrugated adhesives, metal preservatives, water softener, detergent additives, refractory and ceramic raw materials, textile bleaching, dyeing and pulp, mining and beneficiation, waterproof, sealing, wood fire, and adhesives and other food preservation system.
