Ultrasonic cavitation: 50 years of study and process optimization

      Ultrasonic cleaner including ultrasonic generator along with special sensor installed at the bottom of a fluid-filled stainless steel bath. Generator and sensor combination created alternate compression and expansion of liquid with high speed, usually between 25 and 130 KHZ.

      A lot of bubble formation and expand in the liquid in the expansion stage. This is a low stage, essentially "cold sores" water. Water vapor condensation in the foam quickly create a vacuum is full of "space". In the compression stage, a lot of pressure is applied to the new expansion foam cause sudden implosion of foam. Liquid molecular collision release a lot of impact energy, the rapid increase of local temperature produce high-energy liquid flow collision surface cleaning. This collision agitation pollutants adhering to the surface, effectively dislodging them in micron level.

      Cleaning chemistry: effective cleaning medium

      According to the different types of cleaning requirements and substrate, need cleaning detergent solution or similar water medium can greatly increase the cavitation. Reduce the liquid surface tension reducing the energy required to form forming foam, when combined with proper cleaning property solutions results in superior micro cleaned surface soiled.

      Cleaning medium choice (i.e. chemical) is very important. The nature of the substrate and the pollution is the key factor in choosing cleaning chemistry, this is usually water or half hydrophilicity.

      Temperature: optimization maximum efficacy

      Temperature also plays a key role of the cleaning process. Cavitation bubble is proportional to the number of temperature increase. This occurs about 60 ° C over the cavitation began to decline and completely stop when liquid boiling point. However, with temperature and steam pressure increase cavitation energy will reduce. Therefore, each cleaning chemical provides maximum cleaning efficacy in the best temperature Settings.

      Frequency: control your cleaning strength to act
 

      And cleaning chemistry and its properties, select frequency is very important, you clean program.

      The size of the cavitation decision, the energy release of the explosion. This is the frequency of ultrasonic generator. Higher frequency have the small size of the bubble.

      A larger cavity releases more energy detonation lead to a more strong cleaning action. A smaller foam has a mild influence. As a general rule of thumb high frequency to fine particle and cleaning very small characteristic in the matrix and lower frequency is suitable for heavy and thick pollutants.

      Frequency modulation: ultrasonic cavitation evenly distributed

      Frequency variation, modulation, or scanning to prevent the formation of standing wave in the tank. A fixed frequency can produce harmonic vibration, damages of precision components like electronic components. When operating in the scanning mode, ultrasonic generator frequency modulation slightly above and below the central frequency, usually ± 1-4 kHz. Until recently scanning ultrasonics can only in the industrial and high-end professional cleaning system. El and scanning technology can now in all of the desktop ultrasonic cleaning unit
