How does ultrasonic cleaning work?


Ultrasonic cleaning uses the cavitation, acceleration and direct flow effects of ultrasonic waves in the liquid to directly and indirectly affect the liquid and dirt, so as to achieve the purpose of cleaning by dispersing, emulsifying and peeling the dirt layer. In the ultrasonic cleaners used today, cavitation and direct flow gets more application.


1. Cavitation: Cavitation is the transmission of ultrasonic waves to the liquid with a high-frequency conversion method of compressive force and depressurizing interaction of more than 20,000 times per second. During decompression, the phenomenon of vacuum core group bubbles is generated in the liquid. When the compressive force acts, the vacuum core group bubbles produce strong impact force when crushed by pressure, thereby peeling off the dirt on the surface of the object to be cleaned, so as to achieve the purpose of precision cleaning. 


2. Direct current effect: The phenomenon that ultrasonic waves flow in the liquid along the sound propagation direction is called direct flow. When the intensity of the sound wave is 0.5W/cm2, the naked eye can see the direct flow perpendicular to the vibrating surface, and the flow rate is about 10cm/s. Through this straight flow, the oily dirt on the surface of the object to be cleaned is stirred, and the cleaning liquid on the dirt surface also produces convection, which mixes the dissolving liquid that dissolves the dirt with the new liquid, thereby accelerating the dissolution speed and improving the transportation of the dirt with great effect.
