The principle of copper foil ultrasonic cleaning machine
The principle of the ultrasonic generator issued by the high frequency oscillation signal, through the transducer converted into high frequency mechanical oscillation and spread to the medium – cleaning solvent, ultrasonic in the cleaning liquid dense phase forward radiation, so that the liquid flow and produce tens of thousands of diameter of 50-500μm tiny bubbles, Tiny bubbles present in a liquid vibrate under the action of a sound field. These bubbles form and grow in the negative pressure region of ultrasonic longitudinal propagation, while in the positive pressure region, when the sound pressure reaches a certain value, the bubbles increase rapidly and then close suddenly. And when the bubble is closed, the shock wave is generated, and thousands of atmospheres are generated around it, which destroys the insoluble dirt and makes them disperse in the cleaning liquid. When the group particles are wrapped in oil and adhere to the surface of the cleaning part, the oil is emulsified, solid particles and detached, so as to achieve the purpose of cleaning part purification. In this process, known as cavitation, bubbles close to create temperatures of several hundred degrees and transient pressures of more than 1,000 pressures.I suggest you have a look granboultrasonic cleaner. It can be used in 3D print
Advantages of copper foil ultrasonic cleaning machine
The advantages of copper foil ultrasonic cleaning machine are: ultrasonic cleaning effect is good, simple operation. The sound that people hear is the acoustic signal with a frequency of 20-20000Hz. The sound wave higher than 20000Hz is called ultrasonic wave. The transmission of the sound wave propagates longitudinally according to the sine curve, producing a large number of small bubbles. One reason is that the local tensile stress in the liquid and the formation of negative pressure, pressure reduction makes the original dissolved in liquid gas supersaturated, and escape from the liquid, become a small bubble; The other is that strong tensile stresses “tear” the liquid into a hole, called cavitation.
