Application of sodium metasilicate pentahydrate

　　Sodium metasilicate pentahydrate Molecular formula: Na2SiO3.5H2O is a non-toxic, odorless, harmless white powder or crystal granules, soluble in water, insoluble in alcohol and acid and alkaline aqueous solution with detergent, emulsifying, dispersing, wetting, permeability and the PH value of a buffer capacity. Inorganic products are placed in moisture in the air easily deliquescence.

　　It is based on silica content of 90% of quartz powder and sodium oxide content of 38% to 80% of the liquid base material for the reaction, the reaction is cooled after the completion of crystallization obtained.

　　It is widely used in various types of washing industry. In the drilling of crude oil and natural control of mining projects are also used for consistency regulator mud, mud coagulant solution. In the construction industry it is used as a mortar prepared acid, acid-proof concrete and cement accelerator. In the paper industry as adhesives, paper stripping agent ink, paper surface treatment agent. It also can be used as filler soap, detergent, egg preservative, and the vegetation zeolite, silica and fire protection materials. In the ceramic industry, in the ceramic slurry by adding sodium metasilicate pentahydrate inorganic clay particles can increase the surface negative charge, charge exclusion effect to reduce the use of ceramic slurry viscosity, increased mobility, which in ceramic injection molding process can improve efficiency and product quality. sodium metasilicate pentahydrate has the protection and dirt with suspension and emulsion of the light metals (aluminum, zinc, etc.) glassware and ceramics, and the role of some softening properties.
