Produced via the fusion of sodium carbonate and silica sand, sodium silicate powder is supplied in tightly sealed bags, HDPE drums, or jumbo bags to maintain its low moisture content (2.0%) and purity. Proper storage in cool, dry places extends its shelf life to 24 months, ensuring reliable batch performance and maintaining its optimal adhesive and binding capabilities.

FAQs of Sodium Silicate Powder:

Q: How is sodium silicate powder manufactured?

A: Sodium silicate powder is produced through the fusion process, which involves heating sodium carbonate and silica sand at high temperatures, resulting in a highly pure and homogenous powder with excellent alkaline properties.

Q: What are the main uses of sodium silicate powder in industry?

A: Industrially, sodium silicate powder is utilized in detergents, adhesives, water treatment, cement, ceramics, paper, and textiles. It functions as a binder, deflocculant, corrosion inhibitor, and fireproofing agent due to its adhesive and alkaline attributes.

Q: When should I use sodium silicate powder as a deflocculant?

A: Sodium silicate powder is ideal as a deflocculant when improving dispersion and reducing viscosity in ceramic slurries, industrial wastewater treatment, and paper pulp processing, optimizing flow and workability.

Q: Where can sodium silicate powder be safely stored to maintain its quality?

A: Sodium silicate powder should be stored in a cool, dry place in tightly closed containers such as bags, HDPE drums, or jumbo bags to prevent moisture absorption and maintain a shelf life of up to 24 months.

Q: What safety measures are recommended when handling sodium silicate powder?

A: Since sodium silicate powder is an irritant, users should wear gloves, protective eyewear, and avoid direct skin and eye contact. Adequate ventilation and following industrial safety guidelines are essential during use.

Q: What are the benefits of using sodium silicate powder in water treatment and cement production?

A: In water treatment, sodium silicate powder acts as a corrosion inhibitor and water softener, while in cement production, it enhances setting properties, bonding strength, and provides stability by regulating the silicate ratio.

Q: Is sodium silicate powder environmentally friendly and chemically compatible?

A: Yes, sodium silicate powder is biodegradable, exhibits low environmental impact, and is compatible with most inorganic as well as selected organic compounds, supporting a broad spectrum of industrial applications.
