Sodium Silicate (Water Glass)

Description

What is Sodium Silicate Water Glass?

Sodium silicate water glass is a compound derived from sodium carbonate and silicon dioxide. It is characterized by its viscous, glass-like appearance and its ability to dissolve in water. This compound is commonly used in a variety of industrial applications, including the production of adhesives, cements, and detergents. In the world of pyrotechnics, however, sodium silicate water glass is prized for its unique properties and versatility.

Benefits of Sodium Silicate Water Glass

One of the main benefits of sodium silicate water glass is its versatility. It can be used in a wide range of fireworks compositions, from simple fountains to elaborate aerial shells. Sodium silicate water glass is also relatively inexpensive and easy to obtain, making it a popular choice among fireworks manufacturers.

Uses

• Adhesive: Sodium silicate water glass is used as an adhesive in industries where high heat resistance and chemical stability are required. It is often used in the manufacture of cardboard and paper products.
• Cement and Concrete: Sodium silicate water glass is used as a concrete sealer and a component of cement formulations. It reacts with calcium hydroxide in concrete to form calcium silicate hydrate, which strengthens the concrete.
• Detergent: Sodium silicate water glass is used in the formulation of detergents due to its ability to emulsify oils and grease. It helps to remove dirt and stains from surfaces.
• Fireproofing: Sodium silicate water glass is used as a fireproofing agent for wood, fabric, and other materials. When applied, it forms a protective barrier that prevents the material from catching fire.
• Water Treatment: Sodium silicate water glass is used in water treatment processes to remove heavy metals and other impurities. It forms insoluble complexes with these contaminants, which can then be easily removed from the water.
• Textile Industry: Sodium silicate water glass is used in the textile industry as a dye fixative and a flame retardant for fabrics.
• Casting: Sodium silicate water glass is used in the casting of metals, where it is mixed with sand to create molds. It helps to improve the strength and rigidity of the molds.
