Abstract
<p>We washed a soiled stainless-steel (SUS304) surface with attached starch paste as the soiled model because of investigating washing effect of microbubble mixtures generated by a swirling method (S-MB), a pressurized method (P-MB), and a pressurized method with a pressurized tank (NP-MB). Compared with the resultant washing rate of tap water alone, relatively high washing effect of microbubble mixtures was obtained. Furthermore, the washing effect of P-MB approximately agreed with those of S-MB. For understanding the experimental results, particle diameter change against elapsed time and static contact angle of interface between solid surface and droplet of test fluids was discussed. Particle diameters of all microbubble mixtures were changed as elapsed time. Elapsed time until collapse of P-MB higher than that of S-MB. Moreover, NP-MB exhibited highest elapsed time until collapse. Moreover, static contact angle of microbubble mixtures was lower than that of tap water alone. Correlation between washing effect and contact angle was obtained. The obtained knowledges were beneficial for many applications using fine bubble mixtures.</p>
