摘要:
A method of neutralizing an amine gas odor in a cold box process, and an amine gas generator using the method are disclosed. The method includes: making molding sand by mixing sand and forming resin; putting the molding sand into a mold; hardening the molding sand by injecting an amine gas into the molding sand in the mold; and removing an amine gas odor remaining in the mold by injecting an amine gas odor neutralizer into the mold. Accordingly, it is possible to inject an amine gas odor neutralizer in casting of a core or a mold in order to reduce the amine gas odor that remains and leaks through a gap of a mold in the casting. Further, an odor neutralizer is immediately injected simultaneously with discharging of an amine gas, so it is possible to simply remove an odor.
