Theory Of Ultrasonic Cleaning

To understand how the power of ultrasonics is derived, it is helpful to have an understanding of the nature of the energy and its source. Ultrasonic energy is sound at frequencies above the limits of human audibility - above 2OkHz. This sound energy is created by a specialized high frequency vibrator called a transducer. The transducer is powered by an ultrasonic generator which converts line current to alternating electrical energy at the required ultrasonic frequency. The parameters which affect ultrasonic cleaning include temperature, amount of dissolved gas of cleaning solvent and etc. Properly utilized, ultrasonic energy can contribute significantly to the speed and effectiveness of many immersion cleaning and rinsing processes. It is especially beneficial in increasing the effectiveness of today's preferred aqueous cleaning chemistries and, in fact, is necessary in many applications to achieve the desired level of cleanliness. With ultrasonics, aqueous chemistries can often give results surpassing those previously achieved using solvents. Ultrasonics is not a technology of the future it is very much a technology of today.
