Sodium Metasilicate Anhydrous Chemical Properties:

Sodium Metasilicate Anhydrous highly water soluble, but insoluble in alcohol, acid, and salt solutions. Solutions of sodium metasilicate, when heated or acidified, are hydrolyzed to free sodium ions and silicic acid. In moist air, they are corrosive to metals, including zinc, aluminum, tin, and lead, forming hydrogen gas. They are all strong bases reacting violently with acid.Sodium Metasilicate Anhydrous 1

Sodium Metasilicate Anhydrous is a type of silicic acid salt and is classified as an inorganic salt products. It is a non-toxic, odorless and harmless white powder or crystalline particle. It is soluble in water, but not in alcohols or acids. Its aqueous solution is alkaline and is capable of hygroscopy and deliquescence when in contact with air. It has purifying, emulsifying, dispersing, moistening, permeating and PH buffering abilities.

Among inorganic electrolytes, sodium metasilicate’s active alkalinity and PH buffering index is the highest. It has strong moistening, emulsifying and saponifying effect on fats. It is excellent at eliminating, dispersing and suspending impurities, and it can prevent impurities from recollecting.

It has strong cleansing, buffering and neutralizing abilities, can emulsify fats and oils, is an anti-flocculant for inorganic matter, protects metals from erosion, can replace sodium tripolyphosphate in producing detergents and metal cleansing agents, thus reducing the environmental pollution of sodium tripolyphosphate.

Sodium Metasilicate Anhydrous Application:

Sodium Metasilicate Anhydrous is widely used in laundry detergent, ceramics, plating, textiles, printing, papermaking, concrete, cement, fireproof materials, oils, leather processing, and many other industrial fields. Currently, the industries that use it the most are: ceramics, industrial cleaning, laundry detergent, concrete, printing, papermaking, cement, oil mining, etc.

Used in soap, detergent, and bath/washing products. They also have a major use as a builder (a material that enhances or maintains the cleaning efficiency of the surfactant, principally by inactivating water hardness) in soaps and detergents. They are also used as an anticorrosion agent in boiler-water feeds.
