Description

Sodium Metasilicate is an essential industrial inorganic salt, widely recognized for its powerful cleaning, buffering, and deflocculating properties. This versatile compound is a critical component in formulating heavy-duty detergents and industrial cleaners, where it effectively emulsifies oils and suspends soil. Key industries that rely on this high-performance chemical include detergent manufacturing, metal surface treatment, ceramics production, and pulp & paper processing.

Application

• Detergent & Cleaner Manufacture: A core builder in powdered and liquid industrial & institutional (I&I) cleaners, laundry detergents, and dishwashing compounds for its superior grease-cutting and water-softening abilities.
• Metal Surface Treatment: Used in metal cleaning and degreasing formulations, as well as in corrosion inhibitor blends for ferrous and non-ferrous metals.
• Ceramics & Refractories: Acts as a deflocculant and binder in ceramic slips and casting slips, improving workability and green strength.
• Pulp & Paper Industry: Employed in de-inking processes for recycled paper and as a peroxide stabilizer in pulp bleaching.
• Concrete & Cement Treatment: Functions as an accelerator and hardening agent, and is used in formulations for concrete cleaners and hardeners.
• Water Treatment: Serves as a corrosion and scale inhibitor in boiler water and cooling water systems.
• Textile Processing: Used in scouring and bleaching baths for cotton and other fibers to improve wettability and cleaning efficiency.
• Drilling Fluids: Acts as a dispersant and pH control agent in oilfield drilling mud formulations.
