Ultrasonic cleaners refer to cleaning devices that use ultrasound and special cleaning solutions for delicate items. For the cleaning process to be effective, a cleaning solution has to be used. These cleaners are used for optical parts like lenses, jewelry, watches, surgical and dental instruments, coins, electronic equipment, fountain pens and industrial parts. They are usually found in electronic workshops, watchmakers and jewelry workshops. They are the most effective cleaners in medical institutions. During the ultrasonic cleaning process, sound waves are used to agitate in organic compounds. This is how the contaminants that have adhered to ceramics, plastics, metals, glass and rubber are removed. It is an effective process that can remove dirt from blind holes and cracks. When the ultrasonic cleaners are used, all the particles that have embedded on the solid surfaces are easily removed. Solvents like water can also be used but this will depend on the kind of contaminants that you want to remove. Some of the contaminants that can be removed using this process include polishing compounds, soot wax, dust, pigments, flux agents, dirt, dust, fingerprints, grease, blood and oil. One of the main advantages of this cleaning process is that it is possible to clean various sizes of workpieces therefore you do not have to disassemble them before you clean them. To clean an object using this process, it has to be placed inside a chamber in the ultrasonic cleaner. The chamber should have an organic or aqueous compound to aid to make the cleaning process easier. If the cleaner is aqueous, a surfactant is added to get through the surface tension. Cleaning solutions that are water based can be limited when it comes to removing the contaminants therefore it is better to use solvent solutions. The solutions that are used are usually warmed before they are applied. The ultrasonic cleaners are also used in sporting, marine, printing, electroplating, automotive and engineering industries. When choosing ultrasonic cleaners, the type you select will depend on your requirements but there some factors that you should keep in mind to get the right one. Size is one of the most important factors to keep in mind because this determines the kind of items that can be cleaned. The internal dimensions and tank volume of the cleaner that you are using should be appropriate. The cycle time of the cleaners is also important because there are some items that need to be cleaned for longer periods of time. Most of the items require about 15 or 30 minutes of cleaning. If the items that you want to clean have a lot of grime, you need to get cleaner that has a longer cycle. Things like jewelry only require about 10 minutes of cleaning. You also need to make sure that you are using the right frequency when using ultrasonic cleaners. Most of them have an average frequency of 35 or 45 kHz. If you use a frequency that is too high, you can damage the items you are cleaning. Using ultrasonic cleaners needs a good knowledge of this kind of cleaning machine. So ensure that you have skilled manpower which has all the technical knowhow required to operate ultrasonic cleaning equipment.
