この回路をガツシングと言う。 Compressed air (5 to 6
Kg/cm 2 ) is reduced by the pressure reducing valve 10 in the pipe line 7', and the solenoid valve 7 is operated for a set time to reduce the TEA in the vaporizer 2.
When passing through the suction ventilator tube 3, the negative pressure inside the ventilator tube causes the air to flow from the TEA tank 1 to the tube 1.
TEA is sucked through a flow rate adjustment valve 15, a flow meter 14, and a backflow prevention check valve 13 provided at 5'. Operate solenoid valve 7 for a set time and TEA
The compressed air and TEA are sucked in and sent to the demister 17 made of wire wool etc. in the vaporizer 2.
When passing through the demister, TEA is diffused within the demister and exhibits strong vaporization efficiency. The diffused and vaporized TEA gas is sent to the mold 5 to harden the resin sand filled in the mold.
This circuit is called Gatsushing.
