Sodium silicate, commonly known as sodium silicate, is an inorganic substance with the chemical formula of Na2O·nSiO2, and its aqueous solution, commonly known as sodium silicate, is a mineral binder. Its chemical formula is Na2O·nSiO2. It is a soluble inorganic silicate with a wide range of applications.
1.Applications
detergent, ceramic, textile industry, Paper & Printing, construction, metallurgical industry
1. It has the strong capability of cleaning, widely used for the manufacture of a variety of detergents in detergent industry, so it is the best substitute for STPP, reducing environmental pollution.
2. Sodium meta silicate provides anti-corrosion protection to metals (zinc, aluminum, etc.) and is used as metal cleaner and metal surface treatment agents.
3. In the textile industry: mainly used as printing and dyeing auxiliaries, fabric pre-treatment agent and as detergents in cooking and dyeing cotton yarn.
4. In the Paper & Printing Industry: It can be used as adhesives, old paper deinking agent, paper surface treatment agent and printing detergent.
5. In the ceramic industry: used for sludge thinners. It is especially suitable for additives used in slip-casting forming and ceramic forming.
6. In the metallurgical industry: used as inhibitors and dispersing agent of silicon-containing minerals, smelting furnace dispersants, fast-drying agents, and foundry and separating agents.
7. In the construction field: used for concrete dispersion agent and hardening accelerator. It is also used as coagulation accelerator.
