Product Usage

Sodium Metasilicate Pentahydrate is a versatile inorganic salt that integrates cleaning, buffering, emulsifying, and anti-corrosive properties. In the detergent industry, it is a core component for high-performance laundry powders, dishwashing liquids, and industrial cleaners, serving as an eco-friendly alternative to STPP to enhance detergency. In metal surface treatment, it is widely used for metal cleaning and corrosion inhibition, forming a protective film on metal surfaces to suppress acidic erosion. Additionally, it acts as a highly effective dispersant for slurry deflocculation in the ceramic industry and serves as a scouring and bleaching auxiliary in textile dyeing. In the petroleum and construction sectors, it plays a vital role as a mud consistency controller and a concrete accelerator.
