Sodium Silicate 1 Litre For making core sand)

Sodium silicate is mixed with silica sand at proportions indicated. Mix thoroughly and ensure all sand grains are coated. Ram the mixed sand into the core box or mould and vent to the center with a 2mm diameter spike. This is to allow Co2 gas to be passed through the sand. The sand will solidify after 5 to 20 seconds by chemical reaction . The solidified core can then be removed and used in a

Sodium Silicate Binders for Green Sand Metalcasting

The curing of a sodium silicate solution mixed with sand is the result of complex changes that contribute to the hardening of the core or mold. Usually theCO 2 flow rate is 1 5 % based on silicate. Use a dry CO 2 as water is detrimental to gassing speed and overall strengths. Phenolphthalein, at a level of 0.75 % based on sand, may be used as
