Principle of Ultrasonic Cleaning

The principle of ultrasonic cleaning:

Ultrasonic cleaning is based on the effect of ultrasonic cavitation. When ultrasonic waves suddenly rupture (close) after forming bubbles, they can generate over 1000 atmospheric pressures. This continuous and intense instantaneous high pressure strongly impacts the surface of the object, causing dirt on the surface and gaps to quickly peel off, thus achieving the purpose of cleaning and purifying the surface of the object.

Cavitation effect of ultrasound:

The high-frequency oscillation signal generated by the ultrasonic generator is converted into high-frequency mechanical vibration by the transducer and propagated into the medium. The ultrasonic waves radiate forward in a sparse and dense manner in the cleaning solution. When the compression of the sound waves reaches a certain atmospheric pressure, tens of thousands of tiny air pressures are generated. These bubbles form and grow in the negative pressure zone where the ultrasonic waves propagate longitudinally, and quickly close in the positive pressure zone. This phenomenon is called the ultrasonic "cavitation effect", and the pressure required to generate bubbles is called the ultrasonic "air valve" value.

Cleaning process:

Cleaning refers to the removal of liquid and solid contaminants from the surface of a workpiece to achieve a certain level of cleanliness. The cleaning process is a complex physical and chemical interaction between the cleaning medium, pollutants, and the surface of the workpiece. Cleaning is not only related to the nature, type, form, and degree of adhesion of pollutants, but also to the physical and chemical properties of the cleaning medium, cleaning performance, material and surface state of the workpiece. It is also related to cleaning conditions such as temperature, pressure, additional ultrasonic vibration, mechanical external forces, and other factors. Therefore, selecting a scientifically reasonable cleaning process requires process analysis.
