Method Of Ultrasonic Cleaning

Ultrasonic cleaning is used in different industry branches. Ultrasound travels in liquids in form of a longitudinal wave. These longitudinal waves produce areas with overpressure and vacuum which have influence on the evaporation of the liquid.

A liquid is conjoined through cohesions. If the intensity of ultrasonic intensity is increased in the liquid continuously, the liquid will partially evaporate in the vacuum phase and microscopic tiny steam bubbles emerge.

In the following overpressure phase, the steam bubbles implode (cavitation). In this procedure, extreme high forces arise leading to micro blast waves and micro streaming.

The cavitation is influenced by a lot of parameters. It is depending on the external pressure, the temperature, the sonic frequency and intensity, the type of liquid and other sonic values.

Finally, the cavitation causes an excellent cleaning effect comparable to the attack of countless micro brushes.

Advantages of Ultrasonic Cleaning

• Easy handling.
• Shorter cleaning time.
• Less chemistry.
• Low cleaning temperatures.
• Reproducible result .
