What is Cavitation in Ultrasonic Cleaning ?
Ultrasonic cleaners create “Cavitation” within the ultrasonic cleaning liquid during operation –
Cavitation is best described as a repeated formation and instantaneous implosion of millions of microscopic vapour bubbles in a liquid.
Cavitation is created by the very high frequency pressure waves or sound waves, which agitate the liquid in the ultrasonic bath. This agitation produces very high forces on contaminantion adhered to the substrate – (eg. metals, plastics, glass, rubber, ceramics etc). This agitation action penetrates blind holes, cracks, and all recesses. The concept is to thoroughly remove all traces of the contamination – even where tightly adhering or embedded onto the solid surface.
In general terms, the effect of cavitation in an ultrasonic cleaner is described as an army of microscopic scrubbing brushes, working in every possible direction – and it will clean where ever you have a ‘wetted’ surface.
