Experimental Investigation of Improving the Coating Property for Octanol
In slurry made up with sodium silicate binder put into octanol, which can improve the coating property, then gas cavity is repressed or decreased. The quantity addition of octanol is 0.30% quantity of water-glass. JFC is put into ammonium chloride and crystal aluminum chloride hardening liquid, the quantity addition of octanol ranges from 0.05% to 0.10% quantity of ammonium chloride and aluminum chloride, Surface coating and cast quality of shell have a famous effect.
