Sodium Metasilicate Pentahydrate

Sodium Metasilicate Pentahydrate

Properties: sodium metasilicate pentahydrate is a crystal with relative bulk density of 0.8-1.0g/ml, melting point of 72.2 ℃, relative molecular weight of 212. It is easily soluble in water and dilute alkali solution, insoluble in alcohol and acid. The aqueous solution is alkaline, easy to absorb moisture and deliquescence when exposed to air; Strong decontamination capacity and large pH buffer capacity; It has good performances of descaling, emulsification, dispersion, wetting and penetration.

Uses: 1. It is widely used in various washing industries. In the washing industry, such as super concentrated washing powder, washing liquid, washing paste, dry cleaning agent, fiber whitening agent, fabric bleaching agent, etc., it is also widely used as metal surface cleaning agent, beer bottle, floating product dissolver cleaning agent. After full dissolution, it can be used as metal rust inhibitor, scale cleaning agent, electrical parts cleaning agent, and detergent for food industry.

2. It can also be used as mud consistency regulator and mud coagulant in Yunyou and natural drilling control and mining engineering.

3. In the construction industry, it is used as a coagulant for preparing acid resistant mortar, acid resistant concrete and cement.

4. In the paper industry, it can be used as adhesive, waste paper stripping ink agent and paper surface treatment agent.

5. It is used as printing and dyeing auxiliaries and fabric pretreatment agents in the textile industry.

6. It can also be used as filler for soap, detergent, preservative for eggs, vegetation molecular sieve, silicic acid and fireproof materials.

7. In the ceramic industry, adding sodium metasilicate pentahydrate to the ceramic slurry can increase the surface negative charge of inorganic clay particles. The charge repulsion effect is used to reduce the viscosity of ceramic slurry and increase the fluidity, which can improve Gao Xiao's benefit and product quality in the ceramic injection molding process.

8. Sodium metasilicate pentahydrate can provide excellent buffer alkalinity in washing solution, provide anti-corrosion protection for light metals (aluminum, zinc, etc.), protect glassware and porcelain, and have the properties of suspending and emulsifying dirt and softening water.
