During the ultrasonic cleaning process, electrical current is converted into ultra-high frequency sound waves. The resulting high frequency waves create tiny bubbles in the cleaning solution in a process called cavitation.
Depending upon the frequency of the wave, either large or small cavitation bubbles are produced. The lower the frequency, the larger the bubble produced, and vice versa. A larger cavitation bubble upon implosion will exert more energy, increasing its ability to clean the item’s surface.
Four factors determine the efficiency of the ultrasonic cleaning process:
Frequency
The lower the frequency, the larger the cavitation bubble and the greater amount of energy the bubble will release. Frequencies will range from 20-120 kHz. Low frequencies are used for aggressive cleaning applications, while high frequencies are used for delicate cleaning.
Power
Dependent on the type of material and item being cleaned, more or less power will be required to produce the desired frequency.Chemicals
Chemicals are used to dislodge or dissolve surface residues. Depending on the type of material and the manner of damage, a certain chemical formula will be used to achieve the desired result.Temperature
Dependant on the type of chemical being used and the nature of the damage, temperatures may range from 100-180 Degrees Fahrenheit, with the most common range being 140-180 Degrees Fahrenheit. At these temperatures, the cavitation process occurs most efficiently.
The ultrasonic cleaning process can clean smoke, fire, and mold damaged items, large or small, that once may have been unsalvageable. From delicate antiques and fine china to general household items and electronics, a proper ultrasonic cleaning will remove excess residues from your belongings.
