| Abstract: | The paper expounds how to exploit what cheap organic and inorganic resour- ces in Fujian province are to be used as additives for improving the collapsi- bility of sodium-silicate sand. In case CO2 supply is not available, Heat har- dening method can be adopted to cure sodium-silicate while keeping its adequate comprehensive properties of green state strengh, dry state strengh, surface stability, adhering resistance, absorption resistance, and shake-out behavior. It has been tested experimentally in iron and steel casting production, that the result of the me thod is satisfactory. |
