Superiority

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.
 
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.
 
Packing
The inner bag is sealed PE plastic bag while the outer bag is tidely sutured plastic woven or kraft bag.
Net weight: 25kg
Packed in accordance with the requirements.
 
Delivery 
Conveyance must be dry and clean. Handle with care and avoid breaking the bags by edged tools. Protect from rain-drenched and moisture.
