Sodium silicate, or water glass, is produced in the process of melting sand with an adjusted amount of sodium carbonate and this process forms glass. The glass is then melted at a high temperature by a high amount of pressure and results in water glass, or silicates. The consistency of sodium water glass can be described as a thick, clear liquid.
Properties of Sodium Silicate
Sodium silicate’s chemical formula is Na2Si3O7
The dissolution of sodium silicate has a density between 1,26-1,53 g/ml
The relationship between silicon dioxide (SO2), sodium (Na2O), and water (H2O) determines what kind of silicates are going to be formed and what properties the silicates will have. A higher amount of silicon dioxide will give a better water resistance, whereas a higher amount of sodium will lower the viscosity. There are several variants of sodium water glass, and it all comes down to what type of need each customer has.
As many variants that exist of sodium water glass, as many applications can it be used for. Some of the applications where sodium water glass is used are in detergent, process aid in producing powder, protection of washing machines, at water purification plants, sealants in for example tunnels, as well as a stabilizer of the ground.
There is, therefore, an almost endless array of possibilities for application of sodium water glass. We can offer several different products considering the concentration and the properties requested, and we would like to guide you to the right product that fits your need.
