Some statements about ultrasonic cleaning machines are wrongDate: 2022-09-30Number: 214
Some claims about ultrasonic cleaning are wrong.
Aluminum can not be put in an ultrasonic cleaner ー incorrect. As long as the type of cleaning fluid is reasonable, basically all kinds of metals can be put into the ultrasonic cleaning system. As long as the cleaning solution is compatible with aluminum, it can be safely and reliably cleaned, as can magnesium, titanium, and brass.
Putting printed circuit board (PCB) into the ultrasonic cleaning machine will destroy the solder joint-incorrect. Many people improperly point out that an ultrasonic cleaning machine works by removing stains from parts. Obviously, this is not their job. The ultrasonic cleaning system removes contaminants from the surface of parts by creating tiny cavitation bubbles. In fact, ultrasonic cleaning is a very reasonable and effective way to clean PCB.
The ultrasonic cleaning doesn't work -- again, it's not right. Ultrasonic cleaning is very effective in removing contaminants when the best chemicals, cleaning cycle time and temperature are used. The claim may have started with a consumer trying to clean the wrong parts with the wrong chemicals, or using units that are too small to clean. Anyway, that's not true. Hundreds of different companies and industries prove my point to me every day.
The longer the ultrasonic cleaner is in use, the cleaner the parts will be-which is actually true, but only up to a point. If running the cleaner for 3 minutes cleans the part, then running it for 5 minutes may make it cleaner. The user needs to define the cleanliness of the parts. It may be“Clean enough” after only three minutes, or it may take a full five minutes to be considered acceptable. However, there is only a limited amount of contamination on any given component, and once it is gone, it is gone. In this case, if 100% of the contamination and debris disappeared after 15 minutes of ultrasonic cleaning, then another 5 minutes of running would not remove any debris.
If medical and dental tools were cleaned only by ultrasound, they would no longer be sterile -- incorrect. Today, many dental clinics, medical equipment clinics and hospitals use only ultrasonic cleaners to clean and sterilize the tools and equipment of these people. Using reasonable cleaning methods, ultrasonic cleaner can eliminate all possible pathogens, mold and protein contamination on the tool.
Put the parts in an ultrasonic cleaner to clean them. There is no need to remove any contaminants from the components prior to ultrasonic cleaning operations, but the need to remove excess oil, grease and dirt will minimize deposition or residue in the tank, and is conducive to speeding up the cleaning process. This is a legacy of the days when dishes had to be rinsed before being put in the dishwasher. Modern dishwashers effectively remove mashed potatoes from the plate, whether they are 8 inches thick or 3 inches thick. The ultrasonic cleaner does the same thing.
Ultrasonic cleaning machine is not ordinary cleaning equipment, because it can use a lot of materials, can remove all kinds of pollutants, and can be completed in a few minutes, save time and effort! In order for ultrasonic cleaning to be reasonably effective, the chemistry, temperature, and cycle time must be correct; once a reasonable combination is found, virtually anything can be completely and completely ultrasonic cleaning work.
