what is Ultrasonic cleaning…
The range of the human ear is from about 16 Hertz (16Hz) to 16 kilo Hertz
(16kHz), Middle C is 216 Hertz, a grasshopper call around 7 kilohertz and a
bat signal about 70 kilohertz. Beyond human audible range is called
‘Ultrasonic’. Most ultrasonic cleaners operate in the range of 30 to 50 kHz;
ours have an operating frequency of 44-52 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 ‘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.
