What is high frequency ultrasonic cleaning machine? How to choose the ultrasonic frequency?

We all know that the cavitation effect is the main factor in determining the cleaning effect, and the ultrasonic frequency directly affects the cavitation effect, the frequency is inversely proportional to the diameter of the bubble in the liquid, and is proportional to the permeability. The higher the frequency, the shorter the wavelength, the smaller the diameter of the vacuole, low explosion pressure, good permeability, suitable for high surface smoothness, fine workpiece cleaning. In addition, the frequency can not be too high, otherwise the wavelength is shortened, the cavitation effect will be weakened instead, thus reducing the cleaning efficiency. Conversely, the lower the ultrasonic frequency, the easier it is to produce cavitation in the liquid, the greater the strength generated, the stronger the effect.

So what is the high frequency ultrasonic cleaning machine?

Low frequency 17K-23K: suitable for cleaning heavy dirt or more difficult to clean the workpiece, and bubble blast impact on the surface of the workpiece will not cause harm, you should choose low frequency ultrasonic cleaning, for example: auto parts, textile, etc.

Medium-frequency 25K-28K: suitable for cleaning dirt a little heavy or cleaning difficult to moderate, and bubble burst impact on the surface of the workpiece will not cause harm, you should choose medium-frequency ultrasonic cleaning, such as: hardware machinery, electroplating industry, etc.

High-frequency 68K-200K: for cleaning dirt light or easy to clean, and bubble burst impact on the surface of the workpiece will not cause harm, you should choose high-frequency ultrasonic cleaning, for example: semiconductor, silicon wafer coating, special high-precision parts, etc.

Ultrasonic cleaning machine frequency selection.

From the above we understand that the ultrasonic cleaning machine frequency according to the requirements of the cleaning workpiece, the process, the process of different is a strict range of use, different frequency band applicable cleaning products are also different, so it is recommended that if you buy ultrasonic cleaning machine, the specific you can directly ultrasonic cleaning machine manufacturers online consultation.
