Applications of Sodium Metasilicate:
Wash 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 metasilicate provides anti-corrosion protection to metals(zinc, aluminum,ets) and is used as metal cleaner and metal surface treatment agents.
Textile industry: Mainly used as printing and dyeing auxiliaries, fabric pre-treatment agent an as detergents in cooking and dyeing cotton yarn.
Paper & Printing industry: It can be used as adhesives, old paper deinking agent, paper surface treatment agent and printing detergent.
Ceramic industry: Used for sludge thinners,it is especially suitable for additives used in slip-casting forming and ceramic forming.
Metallurgical industry: Used as inhibitors and dispersing agent of silicon-containing minerals, smelting furnace dispersants, fast-drying agents, foundry and separating agents.
Construction field: Used for concrete dispersion agent and hardening accelerator, it is also used as coagulation accelerator.
