Sodium Metasilicate

Sodium metasilicate is a kind of inorganic compound, chemical formula is Na2SiO3, white particles or powder, soluble in water, soluble in dilute sodium hydroxide solution, insoluble in ethanol and acid, mainly used for ultra-concentrated washing powder, detergent, metal cleaning agent, food industry cleaning agent, also used in paper bleaching, cotton yarn cooking, porcelain mud dispersion, etc.  


Synonyms:Disodium Trioxosilicate (nonahydrate); Disodium Metasilicate

Molecular Formula:Na2SiO3 or Na2SiO3·5H2O

CAS RN.:10213-79-3; 6834-92-0

UN NO.: UN 3253

Application:

1. In the washing industry, it is mainly used for ultra-concentrated washing powder, washing liquid, washing cream, dry cleaning agent, fiber whitening agent, fabric bleach agent, etc., and also widely used as metal surface cleaning agent, beer bottle, floating product dissolving agent, etc. When completely dissolved, it can be used as a metal rust inhibitor, scale cleaner, electrical parts cleaner and food industry detergent.

2. In ceramic industry, adding sodium metasilicate pentahydrate to ceramic slurry can increase the surface negative charge of inorganic clay particles. Using charge repulsion to reduce the viscosity and increase the fluidity of ceramic slurry can improve the efficiency and product quality of ceramic injection molding.

3. In the mining industry, it can be used as mud consistency regulator and mud coagulant.

4. In the construction industry, it is used as a coagulant for the preparation of acid-resistant mortar, acid-resistant concrete and cement.

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

6. In textile industry, it is used as auxiliaries for printing and dyeing and fabric pretreatment.

7. It can also be used as soap filler, detergent, egg preservative, vegetation molecular sieve, silicic acid, fire prevention materials, etc.
