Sodium Metasilicate

Sodium Metasilicate

Properties: the relative bulk density of zero water sodium metasilicate is 1.00-1.35g/ml, the melting point is 1089 ℃, and the relative molecular weight is 122. It is a non-toxic, tasteless and harmless product; Soluble in water, insoluble in alcohol and acid, alkaline aqueous solution, easy to absorb moisture and deliquescence in air; Strong decontamination capacity and large pH buffer capacity; It has excellent performances of descaling, emulsification, dispersion, wetting and penetration.

Application: zero water sodium metasilicate has uniform particles, large specific surface area and high oil absorption value, which is conducive to decontamination; The total alkali content of sodium metasilicate zero water and the total content of silicon dioxide are ≥ 95%. Compared with hydrated silicon metasilicate, it improves the binding capacity of calcium and magnesium ions, plays an important role in promoting hard water softening, adjusting and stabilizing pH value, improving surfactant performance, improving work efficiency, decontamination, dispersing and eluting dirt and maintaining good powder structure. Zero water sodium metasilicate will not precipitate crystal water and shows special compatibility and stability to organic chlorine, peroxide and bleaching efficiency in washing. It can replace sodium tripolyphosphate and be used as washing aids for synthetic detergent, metal cleaning, tableware cleaning, public health cleaning, food, meat, dairy processing equipment and other industrial cleaning agents, clay dispersed coagulant, Oil emulsifier, paper deinking agent. It is widely used in ceramics, detergent, textile, printing and dyeing, papermaking, electroplating, coal water slurry, concrete, petroleum and other industries.
