在清洗剂的理化活性一定和它所贡献的机械能有限的情况下,采用了各种强化的方法。传统方法有提高介质的温度、压力和改变介质的流动状态,如增加搅拌或介质的循环等。而近来备受欢迎的强化方法则是增加机械振动、加超声振荡以及采用高压射流等更强有力的措施,并已出现专业化、自动化和机械化等综合技术的配套方法和设施,使零件的清洗走向优质、高效和大批量的佳景。
超声波清洗从20世纪50年代开始,它是利用清洗剂清洗零件表面,并同时以超声波振动来强化整个清洗过程。随着技术的发展已趋于完善并得到了广泛的应用。初期主要用于要求高速和高质量的机械制造业、电子工业、冶金、钟表制造及仪表制造业等,后来也逐渐扩展到其他行业上应用。其清洗作用很大程度上取决于“空穴现象”即超声波辐射器给溶液以高频振动,在扩张的半波期间,溶液的致密性被破坏,形成了直径约为50~500微米的一些微小气泡,气泡充满着溶液蒸汽及溶液沸点下降时,蒸气压力会增大。在压缩的半波期间,空穴气孔很快闭合并产生几十兆帕的局部液压撞击力,在清洗表面上的连续超声波微量爆炸促使污物汽蚀产生裂纹并使清洗液穿透到其中。超声波的空穴效应和清洗液活性对污物的共同作用,加速了清洗过程,作用的结果使污物被破坏并从零件表面脱落而被清除掉。

The physical and chemical activity of cleaning agent and mechanical its contribution to limited circumstances, the various methods of strengthening. The traditional method can improve the flow state of temperature, pressure and the change of dielectric medium, such as increasing the stirring or medium circulation. Strengthening method of recent popular is the ultrasonic oscillation increased mechanical vibration, and using high pressure jet more forceful measures, methods and facilities and has appeared the comprehensive technical specialization, automation and mechanization, make parts cleaning to high quality, high efficiency and large quantities of jiajing.
Ultrasonic cleaning started from the nineteen fifties, it is the use of cleaning agent for cleaning parts of the surface, and at the same time with ultrasonic vibration to strengthen the whole cleaning process. With the development of technology has been perfected and widely used. Initially for the requirement of high speed and high quality manufacturing industry, electronic industry, metallurgy, manufacture of watches and instrument manufacturing industry, then gradually extended to other industry application. The cleaning effect depends largely on the "cavitation" i.e. ultrasonic radiator to solution to high frequency vibration, the half wave during expansion, compact solution is destroyed, the diameter is
