What is Ultrasonic Cleaning?

Ultrasonic cleaning is to use the cavitation effect, acceleration effect and straight flow effect of ultrasonic waves in liquid to directly and indirectly act on liquid and dirt, so that the dirt layer is dispersed, emulsified and peeled off to achieve the purpose of cleaning. In the ultrasonic cleaning machines currently used, cavitation and straight flow effects are more widely used.

Cavitation effect: Cavitation effect is the transmission of ultrasonic waves to liquid in a high-frequency conversion mode of interactive compression force and pressure reduction of more than 20,000 times per second. When the pressure reduction acts, vacuum core group bubbles are generated in the liquid. When the compression force acts, the vacuum core group bubbles are crushed by the pressure to generate a strong impact force, thereby peeling off the dirt on the surface of the cleaned object, thereby achieving the purpose of precise cleaning.

Straight flow effect: The phenomenon of ultrasonic waves flowing in the liquid along the propagation direction of sound is called straight flow. When the sound wave intensity is 0.5W/cm2, the naked eye can see the straight flow, which flows perpendicular to the vibration surface with a flow rate of about 10cm/s. The micro-oil dirt on the surface of the object being cleaned is stirred by this straight flow, and the cleaning liquid on the surface of the dirt also produces convection, and the dissolving liquid that dissolves the dirt mixes with the new liquid, which speeds up the dissolution rate.
