Na2O·mSiO2+(4m+1)H2O+2(m-1)NaOH→m[Na2SiO3·5H2O]
Sodium metasilicate pentahydrate is strongly alkaline, having strong capacity of cleaning, buffering and softening, counteracting acidic contamination, emulsifying fat and oil, deflocculating to inorganic. It can replace STPP to be used for the manufacture of effective detergents and rust remover for metal, reducing environmental pollution, preventing corrosion for metal (zinc, aluminum, etc.). Therefore, sodium metasilicate pentahydrate is widely used for the manufacture of a variety of detergents, used as rust remover for metal, grinding aids for ceramics, deinking agent for paper, dyeing and printing auxiliary for removing oil in textile industry, and also used as the raw material for flameproofing agent, plastic maintenance agent, water retention agent, etc. Used in water reducing agents, sodium metasilicate pentahydrate is able to integrate more hydrones to make better moisture absorption effect.
Sodium metasilicate pentahydrate is an inorganic white powder or crystalline granules, non-toxic, tasteless and environment-safe. It is easy soluble in water, insoluble in alcohol or in acid producing an alkaline solution, very hygroscopic when reacting with CO2 and water from the air. It has the capabilities of removing scale, emulsifying, dispersing, wetting, penetrating, and also has the capability of buffering PH value.

Applications:
?
In 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, aluminium, etc.) and is used as metal cleaner and metal surface treatment agents.
In the textile industry: mainly used as printing and dyeing auxiliaries, fabric pre-treatment agent and as detergents in cooking and dyeing cotton yarn.
In the Paper & Printing Industry: It can be used as adhesives, old paper deinking agent, paper surface treatment agent and printing detergent.
In the ceramic industry: used for sludge thinners. It is especially suitable for additives used in slip-casting forming and ceramic forming
In the metallurgical industry: used as inhibitors and dispersing agent of silicon-containing minerals, smelting furnace dispersants, fast-drying agents, foundry and separating agents.
In construction field:used for concrete dispersion agent and hardening accelerator. It is also used as coagulation accelerator.
