Clean Better With Optimized Ultrasonics!
In order to know the performance capability of an ultrasonic cleaner
, it is first essential to understand the basic principles of ultrasonic cleaning technology and how this is applied in ultrasonic cleaners. First things first, ultrasound is a particular resonance transmitted at a specific frequency that is way below the limits of man's auditory capabilities.
Ultrasonic energy is then produced by piezoelectric transducer specifically at a 40,0000 rate for each second. This process then generates cavitation - an ultrasonic cleaning mechanism. Despite such an intense energy, the parts are safe since it is confined at a microscopic scale.
When a surfactant or wetting agent is added to the bath, this then helps reduce the liquid's surface tension. The decreased surface tension thereby increases cavitation strength. Be aware that medium vapor pressure is highly favorable to ultrasound occurences. Low vapor pressure creates cavitation bubbles which then implode with comparatively significant force yet results in higher threshold for cavitation and a lot fewer bubbles.
Take note that high vapor pressure is not effective since a lot more bubbles are produced yet they easily and less intensely collapse because of a meager external and internal pressure differential. Basically, low viscosity leads to cavitation. Meanwhile, high density produces intense cavitation along with substantial implosive force.
It is highly advisable not to place receptacles or parts directly on the bottom of the
ultrasonic cleaner. Doing so could cause the unit to not function properly since the parts will get to reflect the specific ultrasonic energy to the transducer. Make sure to allow an inch in between the bottom of the tank and the receptacle to allow appropriate cavitation.
Also, it is important for the solution to be placed within an inch of the unit's top where the tray or beaker is in place. In terms of the relationship between the liquid and cavitational activity, it does not necessarily follow that the less the solution is, the more intense the activity. Be aware that units function at its most optimum efficiency when it is filled within an inch from the top. this is especially true of smaller ultrasonic units, such as an
ultrasonic jewelry cleaner.
Then, allow anywhere from five to ten minutes after the equipment has been activated for the solution to go through the process of degassing. Take note that this method does not have to be repeated with continuous use since degassing is required after the bath has been freshly filled.
If you intend to use a basket or tray in order to lower the parts in the solution, it is best to use an openly constructed holder - specifically an insert tray or mesh basket. Make sure these are properly perforated to allow proper drainage. Also, these should provide the sound waves free access to the parts.
It is also important to renew solutions intended for cleaning in order to increase the ultrasonic cleaning activity. Solutions, as with numerous chemicals, tend to become spent with the passage of time. Also, solutions have the tendency to be contaminated with soil particles which then settle on the tank's bottom thereby halting ultrasonic transmission.
