- 대표 도면
- 대표 독립항:
1. An amine gas generator for supplying an amine gas to a mold, comprising: an amine supplier for supplying an amine gas; a gassing line through which the amine gas of the amine gas supplier is transferred into the mold; an odor neutralizer supplier for supplying an odor neutralizer for removing an amine gas odor; a purging line through which the odor neutralizer of the odor neutralizer supplier is transferred into the mold; an air supplier for supplying a compressed air through the gassing line and the purging line to transfer the amine gas and the odor neutralizer with the compressed air; a first regulator for maintaining an injection pressure of the compressed air in the gassing line at a predetermined level; a first valve disposed between the amine supplier and the gassing line for selectively stopping or passing the amine gas through the gassing line; a second regulator for maintaining an injection pressure of the compressed air in the purging line at a predetermined level; a second valve disposed between the odor neutralizer supplier and the purging line for selectively stopping or passing the odor neutralizer through the purging line; and a controller for control opening and stopping operation of the first and second valves, said controller configured to open the second valve after, or simultaneously with closing the first valve for supplying the odor neutralizer through the purging line to remove an amine gas odor in the mold.
