Outline of Final Research Achievements

As fundamental studies for developing a micro bubble jet cleaning method, the effect of addition of surfactants into microbubble water on the stability of microbubble water and detergency and removal effect of surfactant by microbubble shower were studied. The results showed that the microbubble was stabilized and detergency was increased by adding anionic surfactant or nonionic surfactant the concentrations of which are a fraction of the critical micelle concentration. Besides the removal effect of surfactant in rinsing process can be improved by adding microbubble into shower water.
