Applications: Sodium metasilicate anhydrous has strong alkaline, detergency strong buffering capacity, and acid may be in the dirt, so that fat and oil emulsification, flocculation of the inorganic counter-effect on the metals against corrosion, can be used in place of sodium tripolyphosphate synthetic detergents and metal cleaning agent effective to reduce the sodium tripolyphosphate to the environmental pollution. Zero Water Sodium Metasilicate is widely used in various configurations lotion, metal surface treatment, ceramic grinding aids, fire-resistant agent of raw materials, Paul aquasorb plastic raw materials, textile auxiliaries degreasing and paper deinking agent.
