sodium metasilicate anhydrous

Na2SiO3

HS CODE：28391100

UN NO.:3253

Properties

Sodium metasilicate anhydrous is an inorganic white powder or crystalline granules, non-toxic, tasteless and environment-safe. It is easily soluble in water, insoluble in alcohol or 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.

Principle applications:

1. Drilling

2. Textile process

3. Dairy cleaning

4. Floor cleaning

5. Detergent formulations

6. Dishwashing compounds

7. Metal cleaning

8. Industrial cleaners

9. Soil stabilization
