Sodium Metasilicate Anhydrous
Product Name:Sodium Metasilicate Anhydrous
Molecular formula: Na2SiO3
Molecular Mass: 122.07
CAS Number: 6834-92-0.
Characteristic
Being white crystallized powder, sodium metasilicate, pentahydrate can easily solute in water and sig water, while hardly in alcohol and acid. Its water solution exhibits alkalescence. Absorption of moisture and deliquescence will happen when bared in the air.
Sodium metasilicate, pentahydrate shows the abilities of detergent; emulsion; dispersion; humidification and pH buffering.
Application
Sodium metasilicate is used in fireproofing mixtures; in laundry, dairy, metal, and floor cleaning; in deinking recycled paper products in the pulp and paper industry; in washing carbonated drink bottles; in insecticides, fungicides, and antimicrobial compounds; and as a chemical intermediate for silica gel catalysts, an additive in soaps and synthetic detergents, an ingredient in adhesives, a bleaching aid, and a boiler compound. In detergents, sodium metasilicate has been used as a precipitating builder for calcium and magnesium. In cosmetic formulations, it is a chelating agent and corrosion inhibitor; 77% of 168 formulations was used in hair dyes and colors. It has also been used in flotation materials at fruit packing plants. Its gel-forming property has been employed in soil stabilization.
Storage and Packing
It should be kept away from rain, moisture and direct sunlight during storage and transportation.
