Fast Clean 40khz Ultrasonic Cleaner With 2-30L Capacity Tank
The advantages of ultrasonic cleaning machine are: good cleaning effect and simple operation. The sound that people hear is a sound wave signal with a frequency of 20-20000Hz, and sound waves above 20000Hz are called ultrasonic waves. The transmission of sound waves propagates longitudinally along a sinusoidal curve, producing a large number of small bubbles. One reason is that the local tensile stress in the liquid forms negative pressure, and the decrease in pressure causes the gas originally dissolved in the liquid to supersaturate and then escape from the liquid into small bubbles; Another reason is that the strong tensile stress "tears" the liquid into cavitation, which is called cavitation.
