Sodium Metasilicate Pentahydrate: A Key Chemical Solution for Global Cleaning and Industrial Applications

Excellent Crystal Structure and Solubility

Sodium Metasilicate Pentahydrate features a stable and well-defined crystalline structure, providing excellent flowability and fast dissolution performance. Its high solubility in cold water allows it to disperse quickly during chemical formulation processes, reducing agglomeration problems and improving production efficiency.

Strong Alkalinity and Stable Buffering Performance

With a Na₂O content typically ranging from 28.7% to 30%, Sodium Metasilicate Pentahydrate provides strong alkaline performance and effective pH buffering capability. It can efficiently neutralize acidic contaminants and maintain a stable alkaline environment during cleaning processes, ensuring consistent cleaning performance even under heavy-duty conditions.

Excellent Chelating and Dispersion Capability

Sodium Metasilicate Pentahydrate has outstanding water-softening properties by effectively binding calcium and magnesium ions in hard water. Meanwhile, it helps disperse and suspend dirt particles, preventing their re-deposition onto surfaces and improving overall cleaning efficiency.

Laundry Detergents

Sodium Metasilicate Pentahydrate acts as an effective alkaline builder in detergent formulations. It improves detergency performance, enhances soil removal, softens water, and helps prevent fabric dullness caused by repeated washing. As a phosphorus-free builder, it is also considered an environmentally friendly alternative in modern detergent formulations.

Industrial Cleaning Agents

In heavy-duty industrial cleaning applications, Sodium Metasilicate Pentahydrate effectively removes oil, grease, and organic contaminants from machinery, equipment, pipelines, and industrial surfaces. Its strong emulsifying and dispersing capabilities make it an important ingredient in industrial degreasers.

Metal Cleaning Applications

Sodium Metasilicate Pentahydrate is widely used in metal cleaning formulations. It helps remove grease and contaminants from metal surfaces while forming a protective silicate layer that improves corrosion resistance, especially for sensitive metals such as aluminum and copper.

Cement Additives

Sodium Metasilicate Pentahydrate can be used as a functional additive in cement-based materials. It promotes early strength development, improves material performance, and contributes to faster setting processes in specific construction applications.

Waterproofing Materials

Through chemical reactions with cement components, Sodium Metasilicate Pentahydrate can generate insoluble silicate compounds that help fill micro-pores within concrete structures. This improves compactness and enhances resistance against water penetration.

Textile Processing Auxiliaries

In textile bleaching processes, Sodium Metasilicate Pentahydrate functions as an effective hydrogen peroxide stabilizer. It helps control peroxide decomposition, improves bleaching efficiency, and protects textile fibers during processing.

Paper Processing Applications

Sodium Metasilicate Pentahydrate is used in waste paper de-inking formulations. It assists in separating ink particles from cellulose fibers, improving pulp brightness and supporting the production of higher-quality recycled paper products.
