A cooling system
The manufacture of water-soluble sodium silicate (water glass) does not include a forming process after the melting phase. The glass must simply be cooled down in a controlled way. A special plate conveyor with a heat resistant surface has been developed for this. The glass flows onto the plates directly from the melter and cools as a result of air convection. It is then crushed to obtain the necessary grain size. Dissolved in water, sodium silicate is used in many products such as detergents, colours and adhesives.
