I. BRIEF INTRODUCTIONS The ultrasonic cleaning makes use of the effect of cavitations and the sonic-pressure, which are generated in the liquid by the powerful ultrasonic. Besides, the ultrasonic can clean the stuff with the liquid detergent. The process of ultrasonic cleaning likes as below the liquid detergent with the action of ultrasonic wave generates numerous micro vacual bulbs, these bulbs will contract and expand repeatable, resulting from the action of sonic-pressure. Once these bulbs blow out, the exposition forces may strike off the contaminated spots adhered to both on the surface everywhere and in those shrunk corner places. If right amount clean liquid is added in the process, the clean efficiency will be better because of its permeating and dissolving action. For the action of ultrasonic wave occur in the liquid, what are the stuff will be, once it gets in touch with the liquid, it can be cleaned thoroughly. The clear process is especially fitted for those have complicated shape or many cracks also for smooth or weak stuffs that can1t be cleaned by hard instrument. Its general uses can be roughly listed as below: Jeweler, diamond, spectacles, watch parts, knitting matters, seals, false teeth, pens jetting mouth, milk bottle,fruit, and it also can be used to remove nail enamel for ladies, it’s fit for medical machine (surgical instruments)and so on.
