 White Granular Anhydrous Sodium Metasilicate As the Silicate Chemical  

 

 

Sodium metasilicate anhydrous is strongly alkaline, having strong capacity of cleaning, buffering and softening.

 

 

1. Introduction for sodium metasilicate anhydrous

 

 

Sodium metasilicate anhydrous 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 anhydrous 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. 

 

 

 

2. Properties

 

 

Sodium metasilicate anhydrous 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.
