Sodium Silicate,CAS:1344-09-8,H.S code:2839191000

Sodium silicate, also known as water glass, has a variety of industrial applications due to its adhesive, binding, and sealing properties. Here are some of its key uses:

1. Adhesives and Binders
Paper and Cardboard Production: Sodium silicate is used as a bonding agent in the manufacturing of corrugated cardboard and paperboard products.
Wood and Laminates: It serves as a glue for wood, veneers, and other laminated materials.
2. Detergents and Soaps
Laundry Detergents: Acts as a builder, enhancing the cleaning power of detergents by softening water and stabilizing bleach.
Dishwashing Soaps: Used in industrial and household cleaning agents for its ability to break down fats and oils.
3. Textile Industry
Fabric Treatment: Used to enhance the dyeing process and as a stiffening agent in fabrics.
4. Construction Materials
Cement and Concrete: Sodium silicate improves durability, water resistance, and strength in concrete and mortars. It's also used to seal cracks in concrete and to make refractory cements for high-temperature applications.
Fireproofing: Mixed with other materials, it acts as an insulating or fireproofing agent.
5. Water Treatment
Water Softening: Used in water treatment plants to reduce hardness by binding calcium and magnesium ions.
Corrosion Inhibition: Prevents corrosion in pipes and boilers by forming a protective layer.
6. Chemical and Metal Industry
Foundry: Used as a binding agent for molding sand in metal casting processes.
Catalyst in Chemical Reactions: Plays a role in synthesizing other chemicals and as a stabilizer in various processes.
7. Automotive and Industrial Maintenance
Radiator Sealants: Used as a sealant in automotive radiators to stop leaks.
Anti-Corrosive Coating: Applied to metal surfaces to prevent corrosion and oxidation.
8. Ceramics and Pottery
Glazing and Clay Work: Used in the production of ceramic glazes and to harden pottery materials.
9. Agriculture
Soil Stabilizer: Used in agriculture to stabilize and enhance soil structure.
10. Passive Fire Protection
Fire Doors and Insulation Panels: Applied in fire doors and insulation materials to provide a passive fire protection layer.
Its versatility makes sodium silicate an essential material in many industries, often used to improve strength, durability, water resistance, and chemical stability.
