Water glass casting refers to the process in which water glass is added into the molding materials in proportion (usually silica sand) and then gets stirred and mixed for 6-8 min, and then grinded into "sodium silicate-bonded sand". Then the sand is put into the mould boxes in which CO2 has been much blown into. CO2 starts the chemical reaction with the water glass to form the silica gel which hardens the sodium silicate-bonded sand. Then the whole casting process is complete after drawing, mould assembling and pouring procedures.
Features of water glass casting:
1. Simple equipment.
2. Little investment.
3. Regeneration and recovery rate of the used sand as high as 90%.
4. Environmental friendly: sand washing sewage can be reused after treatment, thus realizing zero release of sewage; used sand is regenerated through wet process almost without producing dust in the environment.
5. Low cost.
