SODIUM METASILICATE PENTAHYDRATE

Sodium metasilicate pentahydrate, commonly known as instant water glass, belongs to the category of inorganic salt products. It is a silicon based fine chemical product developed by European and American companies in the 1960s. French companies such as Rhone Planck, American company Daxiang, and Swedish company EKA all have a production capacity of tens of thousands of tons. It is a non-toxic, odorless, and pollution-free white powder or crystalline particle that is easily soluble in water. It is insoluble in alcohol and acid, has water absorption, and the aqueous solution is alkaline. When placed in air, it is easily hygroscopic and deliquescent. It has the ability to remove scale, emulsify, disperse, moisten, penetrate, and slow down the pH value. It has strong cleaning power and a large pH buffering ability. It can neutralize acidic pollutants, emulsify fats and oils, and has a anti flocculation effect on inorganic substances, It also has an anti-corrosion effect on metals.
