what is ultrasonic cleaning?...
The audible frequency range of the human ear is from about 16 Hertz (16
Hz) to 16 Kilohertz (16 kHz), Middle C is 216 Hertz, a grasshopper call
around 7 kHz and a bat signal about 70 kHz. Beyond human audible range
is called ‘Ultrasonic’. Most ultrasonic cleaners operate in the range of 30 to
over 70 kHz; ours have an operating frequency of 45 to 55 kHz.
Ultrasonic cleaners function by producing sound waves that are
transmitted into the tank and cleaning solution. These waves create
millions of microscopic bubbles, which collapse or ‘implode’, releasing
large amounts of energy, which scrub the surface clean. This process is
called ‘Cavitation’.
Ultrasonic cleaners have many applications including the cleaning of:
Dental Instruments
Dentures
Endoscopes
Veterinary Instruments
Chiropody Instruments
Clocks and Watches
Jewellery
Printed Circuit Boards ... and many more.
A ‘generator’ located within the ultrasonic cleaner develops the high
frequency power. This supplies the power to the Piezo or ‘transducer’,
which creates the sound waves in the tank. Apart from the strength of the
ultrasonic waves, an equally important part of the cleaning process is the
solution used. An incorrect solution will slow down the cleaning process
and cause poor results.
