Applications of Sodium silicate :

(1) Sodium silicate is the most valuable filler in the soap making industry. The addition of sodium silicate into laundry soap can buffer the alkalinity of laundry soap, reduce the loss of laundry soap in water, and enhance the washing ability and prevent soap rout;

(2) Sodium silicate plays the role of helping wash, preventing corrosion and stabilizing foam in synthetic detergent;(3) Can be used as papermaking filler;(4) For the manufacture of silicone gel and silica gel;(5) Used as a binder in the casting industry, bonding sand and clay, making a variety of molds and cores that people need.
