Ultrasonics – The faster, safer way to clean.
EXPLANATION OF ULTRASONICS
A high tech ultrasonic cleaner works as a result of sound waves being introduced into a cleaning liquid by means of a series of transducers mounted onto the cleaning tank. The sound travels throughout the ultrasonic cleaner’s tank creating waves of compression and expansion in the liquid. In the compression wave, the molecules of the cleaning liquid are compressed together tightly. Conversely, in the expansion wave, the molecules are rapidly pulled apart. The expansion is so dramatic that molecules are ripped apart, creating microscopic bubbles. The bubbles are unable to be seen by the naked eye because they are so small and exist for only a split second of time. The bubbles contain a partial vacuum while they exist. As the pressure around the bubbles becomes greater, the fluid around the bubble rushes in, collapsing the bubble very rapidly. Ultrasonic equipment manufacturers take advantage of the associated phenomena to deliver ultra-precise cleaning capabilities. When the bubbles collapse, a jet of liquid is created that travels at an extremely high rate. An associated rise in temperature as high as 5000 degrees C occurs; this is roughly the temperature of the surface of the sun. This extreme temperature, combined with the liquid jet’s velocity provides a very intense cleaning action in a very concentrated area that ultrasonic manufacturers can use. Because of the very short duration of the bubble expansion and collapse cycle, the liquid surrounding the bubble quickly absorbs the heat and the area cools rapidly. As a result, the tank and liquid only becomes warm and does not heat excessively due to the introduction of parts in the ultrasonic washing equipment.
