乳剂中溶解的气体可用脱气装置去除。脱气装置为一水平放置的圆柱式容器。乳剂从容器下端进入,脱气后从另一端下部排出。上部为排气室,下面为带有喇叭的超声波振荡器。其喇叭位于容器底孔中间,并伸到乳剂中。乳剂在重力作用下从贮槽自流到容器中,流量可由水平感受器所控制的流量阀调节,使容器内乳剂保持一稳定液面。乳剂中排出的气体可由真空泵排出。排气时真空度要低,以免因真空度过高而造成液体沸腾。脱气后的乳剂可以直接送去涂 The dissolved gas in the emulsion can be removed by degassing. The degasser is a horizontal cylindrical container. The emulsion enters from the lower end of the container and is degassed and discharged from the lower part of the other end. The upper part of the exhaust chamber, below the ultrasonic oscillator with a horn. The horn is located in the middle of the bottom of the container and extends into the emulsion. The emulsion gravity flows from the sump into the container, and the flow rate can be adjusted by a flow valve controlled by the level sensor to maintain a stable liquid level in the container. The gas discharged from the emulsion can be evacuated by a vacuum pump. When the exhaust gas vacuum is low, so as to avoid excessive vacuum caused by liquid boiling. Degassed emulsion can be directly sent to Tu
