超音波を併用したマイクロバブル充満洗浄

―洗浄試料の狭隘部に着目した場合―

抄録

In recent years, the precision machines and mechanical parts have become more and more complicated, therefore, it is necessary to develop a cleaning technology for narrow area, that is environment friendly. In this study, the effect of the presence or absence of a narrow space on the cleaning effect experiments was clarified using two-dimensional and three-dimensional specimens with ultrasonic cleaning, microbubble-filled cleaning, and microbubble-filled cleaning combined with ultrasonic cleaning on the back and narrow space. The results showed that microbubble filling combined with ultrasonic cleaning in narrow area had an advantage over ultrasonic cleaning in that the amount of residual oil was higher, but the surface of the specimen was cleaned evenly.
