Sodium silicate is a kind of inorganic chemicals.Used as a binder is sodium silicate hydrate, also known as water glass. Because it has the following basic properties: strong adhesion, high strength, acid resistance, heat resistance, alkali resistance and water resistance. Chemical formula Na2SiO3·9H2O
The coagulation and solidification of water glass in air is very similar to that of lime, and is mainly achieved through two processes of carbonization and dehydration crystallization.
