About Ultrasonics
How Ultrasonics Work
Ground-In dirt and grime can be extremely tedious and time-consuming to remove by hand,
however, it becomes easy with the use of ultrasonic cleaners. A wide range of parts can be
cleaned by the ultrasonic process to a 'Like New' condition with the right detergent/solvent
without damaging the part.
A physical effect called "acoustic cavitation" generated in the liquid is responsible for the
cleaning process. Cavitations form when ultrasonic waves travel through liquid. When a sound
wave travels through fluid it stretches and compresses the liquid to transmit the sound, as
the amplitude of such sound waves increase to a critical level the negative pressures create
cavities in the water.
As these cavities collapse high temperatures and large forces are generated in a very localized
area, the accumulative effect of millions of these collapsing cavities is responsible for the
cleaning action and are particularly effective when used with the correct detergent/solvent.
Cavitation takes place where ever the liquid comes into contact with the object being cleaned, for
example;
Fine recesses/cracks and obscured chambers to clean where many other cleaning methods
cannot reach.
Objects Ultrasonics Can and Can't Clean
Ultrasonic cleaners can be used to clean just about anything. The list below names the most
common items cleaned by ultrasonics:
•
Taps, Dies, Milling cutters,
•
Engine Blocks,
•
Carburetors,
•
Jewellery (Gold, Silver and Platinum)
•
Waterproof watches
•
CD's and DVD's,
•
Medical equipment / instruments (ultrasonic cleaning does not sterilize, it
must be followed by sterilisation in an autoclave)
•
Dentures,
•
PCBs / assemblies (clean with caution, see operational advice below)
•
Golf clubs,
•
Ceramics,
•
Paint spray guns,
•
Tattooing equipment (ultrasonic cleaning does not sterilize, it must be
followed by sterilisation in an autoclave)
•
Printer heads,
•
Diving respirators,
•
Bike parts and much more.
Most objects can be processed in an ultrasonic tank but there are some exceptions including
some plastics, precious stones and electronic components. We advise checking with the
manufacturer of the objects to be cleaned whether they are suitable for ultrasonic cleaning.
