The role of high-frequency ultrasonic cleaning machine

Date: 2022-11-23Number: 1077

The cleaning principle of the ultrasonic cleaning machine is to obtain“Cavitation effect” in the cleaning fluid, that is, the cleaning fluid to form stretching and compression conditions, when the cleaning fluid will form a large number of fine bubbles, the bubbles will break up when the cleaning fluid is compressed. The local pressure at which these bubbles form and break up can reach the impact force of thousands of atmospheres, a pressure so strong that it is enough to cause changes in the molecules of matter, cause a variety of chemical and physical changes (decomposition, chemical, emulsion, dispersion, etc.) , can be used to completely remove the surface of the object from the floating ash, oil stains, rust and other impurities.

The frequency is inversely proportional to the bubble diameter in the liquid and directly proportional to the water permeability. Higher frequency, shorter wavelength, smaller bubble diameter, low explosion pressure, good water permeability, suitable for surface smooth, fine workpiece cleaning. In addition, the frequency can not be high, or shorten the wavelength, cavitation will become weak, thus reducing the efficiency of cleaning.

On the contrary, the lower the frequency of ultrasound, the easier to obtain cavitation in the liquid, the greater the force formed, the stronger the role, mainly for the surface rough and slightly difficult to clean stains. Ultrasonic frequency will also affect the work of the high-frequency noise, the lower the frequency, the greater the noise, usually in line with the cleaning effect, try to choose a relatively high frequency.

high frequency ultrasonic cleaning machine

This is based on the following principles:

Low-frequency 17K-23K: it is mainly used to clean the heavy stains or slightly difficult to clean the workpiece, and bubble engineering explosion impact force on the surface of the workpiece will not cause damage, should choose low-frequency ultrasonic cleaning machine, for example: Auto Parts, textile and so on.

Intermediate frequency 25K-28K: it is mainly used to clean the stain slightly heavy or the cleaning difficulty coefficient is relatively moderate, and the bubble engineering blasting impact force will not cause damage to the surface of the workpiece, should choose the intermediate frequency ultrasonic cleaning machine, for example: hardware equipment, electroplating industry.

Medium and high frequency 33K-60K: it is mainly used to clean the stain light or relatively easy to clean, and bubble engineering blasting impact force on the surface of the workpiece will not cause damage, should choose medium and high frequency ultrasonic cleaning machine, optical glass, electronic component, etc. .

High-frequency 68K-200K: it is mainly used for cleaning stains light or easier, and bubble engineering blasting impact on the surface of the workpiece will not cause damage, should choose high-frequency ultrasonic cleaning machine, for example: List of semiconductor materials, unique high-precision parts, etc. .

Because of its unique cleaning technology ultrasonic can achieve better cleaning results than spray, infiltration, steam and manual methods, etc. , it is widely used in machinery, surface treatment, List of semiconductor materials, optics, electronics, light industry, textile, chemical industry, aerospace, shipping, medical and pharmaceutical industries, such as workpiece cleaning and analysis of the object of crushing, emulsification, dispersion, solubilization, extraction principles, defoaming degassing, accelerating chemical reactions, etc. .
