Sodium Silicate Sand Casting

Sodium silicate is a generic name for chemical compounds with the formula
Na2SiO3. This material is generally colorless transparent solids, or in white
powder, non toxic and non-inflammable. It is suluble in water in various
amount. A more common name for sodium silicate is water glass, which is used in
the iron or steel sand casting. The water glass works as a binder of the sand.
It allows the rapid production a strong sodium silicate sand casting mold, by
CO2 through the mixture of sand and sodium silicate in the mold, which hardens
it almost instantly.

Notice of Sodium Silicate Sand Casting
Though in most conditions, sodium silicate sand casting is considered to be
investment casting, but actually it also could be applied in the sand casting.
Besides, sodium silicate sand casting is more suitable to make the large and
complex structures and with even better surface finish and less defects.

Principle of Sodium Silicate Casting
The principle of sodium silicate casting industry and the detailed steps: melt
the glass and mold it through the mold. Generally realize that after the mold
is made, the glass melt is injected into the mold or realize that the pre-made
mold is stacked with glass scrap in the mold, and put into the furnace together
with the mold for melting, and anneal the mold with the glass domain
anastomosis after molding.
