Raw materials of Sodium silicate
- Silicon dioxide (SiO2 out of pure silver sand)
- Disodium oxide (Na2O)
- Water
Application
Because of its unique properties, sodium silicate is found in a huge area of applications. Sodium silicate is used to manufacture detergents, catalysts, TiO2 , absorbing agents, (fire resisting and acid-proof) cements, moulds; it is also used in the water purification field, boarding, de-inking of paper, purification of metal surfaces, ... In addition, because of its interesting binding properties, sodium silicate is used as an aid in processing.
Solid sodium silicate, to be packed in 50kg; 1000kg; 1200kg; 1250kg jumbo bag
Liquid sodium silicate, to be packed in 295kg iron drums (loading 23.6mt per 20ft container)
