Sodium Metasilicate
Also known as anhydrous sodium metasilicate, formula Na2SiO3, it appears as white granules or powder. Its uniform particles, large specific surface area and high oil absorption value help remove oil stains.
With total alkali and silicon dioxide content of no less than 94%, it has a higher binding capacity for Ca and Mg ions than hydrated sodium metasilicate, and plays an important role in softening hard water, regulating and stabilizing pH, improving surfactant performance, enhancing detergency and maintaining a good powder structure. It does not release crystal water and shows excellent compatibility and stability with organochlorines, peroxides and bleaching synergists in detergents, with a builder effect noticeably better than hydrated sodium metasilicate. Widely used in various detergents, metal surface treatment, water-retaining agent raw materials, degreasing, textile printing and dyeing auxiliaries and paper deinking agents.
