Ultrasonic cleaning is currently the most effective and indispensable cleaning method in industry. Ultrasonic cleaners are instruments that use the chemical cleaning agent of ultrasonic waves combined with cavitation to clean workpieces. Firstly, the dirt is infiltrated and dissolved by the chemical action of the cleaning agent. Then, the impact force generated by ultrasonic cavitation peels off the dirt layer on the surface of the object, and it is stirred, dispersed, emulsified to prevent the dirt that has already detached from the surface of the object from reattaching to the object.
