Sodium Metasilicate Pentahydrate
Sodium Metasilicate Pentahydrate, also named Pentahydrate Sodium Metasilicate, 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. It is strongly alkaline, having strong capacity of cleaning, buffering and softening.
The solution is alkaline, which presents detergency, emulsibility, dispersity, wettability, permeability and the buffer ability to the PH value, very hygroscopic and deliquescet when exposed to the air. Strong solution has a corroding effect on textile and skin.
