Applications of Sodium Silicate
Engineered chemical solutions supporting foundational manufacturing processes globally.
Detergent Industry
Sodium silicate is widely used in the detergent industry as a builder and alkaline agent. It enhances cleaning performance, softens water, prevents dirt from redepositing on fabrics, and improves the stability of both powder and liquid detergents.
Water Treatment
Sodium silicate is widely used in water treatment as a corrosion inhibitor and coagulant aid. It helps protect metal pipelines and equipment from corrosion while improving the removal of suspended solids and impurities, resulting in cleaner and safer water.
Construction Chemicals
Acts as a vital accelerator and binder in cement and concrete formulations, improving structural integrity, reducing setting time, and enhancing overall durability.
Refractory Materials
Serves as an essential high-temperature binder in the manufacturing of refractory bricks and monolithic linings, offering excellent thermal stability and resistance to chemical attack.
Paper Industry
Used extensively for de-inking recycled paper, stabilizing peroxide bleaching, and serving as a sizing agent to enhance overall paper strength, brightness, and finish.
Floor hardener
The advantages of using sodium silicate as a floor hardener: it is hard and durable, easy to maintain, and safe and environmentally friendly.
Ceramics
Serves as a highly effective deflocculant in ceramic slips, reducing viscosity and water content while significantly improving the structural integrity of the final ceramic body.
Mining & Mineral Processing
Employed in mineral processing and ore flotation as a dispersant and depressant, enhancing the separation efficiency of valuable minerals from gangue materials.
