Ultrasonic baths clean everything from pollution

Many readers ask why an ultrasonic bath is needed, does it really clean any surfaces from old deposits and contaminants. Yes, this is a scientifically proven fact - such products are indispensable assistants to professional electronic engineers, are used at aircraft repair enterprises and service stations, and jewelers also use it to completely clean jewelry.

If you are interested in the principle of ultrasonic cleaning, you want to fill in the horizons of your horizons in this matter in order to find out all the advantages of such devices, to learn more about the specifics of application and technical nuances, then read this article carefully.

What it is

We all know from the school curriculum that ultrasound is an oscillation that is not audible to the human ear, but the correct use of it has led scientists from different countries to fantastic discoveries. Ultrasonic baths are able to clean any objects from the smallest pollution. If you remember, at the end of the last century, an advertisement appeared that constantly showed a unique small-sized device that can replace a washing machine.

Many ordinary people thought that this was yet another action to entice money out of users, but this was not so - it was the first household ultrasonic device capable of cleaning clothes in a record short time. In this case, the cavitation effect is used, when millions of air bubbles appear on the surface of the tissue, bursting, they clean the surface of contaminants, since the microexplosion of each of them is quite strong.

Ultrasonic modern device has the following main details:

1. Capacity with a volume of 0.5-30 liters.
2. The emitter, operating in the range of 20-40 kHz, it is located outside, under the bottom of the device and is controlled by an electronic unit. Its task is to transform the electrical vibrations that ultrasound creates into mechanical ones, transferring them to the bath fluid through the walls.
3. Generator - it is he who serves as the source of the appearance of ultrasonic vibration.
4. The heating element is its task to maintain a constant temperature of the liquid at + 70 ° C. Such an element is not always included in the design of models, but it really helps to better clean any surfaces.

Water, alcohol, some types of fuel are used as filling liquid, but they must be handled with extreme caution because they are explosive. At home, make a solution based on hot water and washing powder without abrasive particles and the whitening effect.

Principle of operation

As we mentioned earlier, such a product works to create a myriad of small air bubbles that, when exploding, clean hard-to-reach spots from extraneous layers. In laboratories, such bathtubs are used to accelerate emulsification, dissolving with stirring, extraction, etc., as well as cleaning laboratory glassware of reagents used.

Application area

In medicine, such devices are used to clean surgical instruments from biological contaminants, in preparing them for subsequent processing by prolonged boiling. They are used in dental clinics, laboratories of various profiles.

Actively ultrasonic cleaners are used in many areas:

1. In mechanical engineering, they play the role of an aggregate that removes contaminants from pipes and especially large parts after their final grinding and polishing.
2. They are widely used in jewelry when it is necessary to clean jewelry that has lost its presentable appearance, for example, silver fades over the years.
3. Printing houses in such bathtubs clean the details of printers and other devices responsible for printing.
4. Production of electronic devices - for cleaning quartz and silicon wafers.
5. In service stations, nozzles, injectors and fine filters are cleaned with their help.

A mobile phone that has fallen into water can be repaired by washing the electronic board in an ultrasonic cleaner, which is done in service centers. The master removes from it all the details that do not want contact with the aqueous solution, lower the board into the tray and set the desired frequency. After ten minutes, all the functions of your mobile device will be restored.

How to choose

Today, manufacturers have flooded the market with small ultrasonic baths, because this particular type is in great demand.

When choosing a similar device, experts advise paying special attention to such parameters:

1. Frequency range - the higher the frequency, the more active the solution is drilling, and this contributes to a better removal of contaminants from hard to reach places. For medical institutions they purchase products with a frequency of at least 70 kHz.
2. The size of the internal container. To choose the best option, you must first find out what maximum size the parts will be cleaned, we must not forget about such a nuance that the ideal location is at a distance of 30 mm from the bottom. All large-sized items for cleaning are suspended or in a special plastic basket that comes with the kit - this eliminates possible damage to the equipment.
3. Fluid heating. It is no secret that heating speeds up the cleaning process, therefore, for perfect cleaning, many manufacturers equipped the bathtubs with heating elements to create a temperature inside of up to 65 degrees.
4. Timer - its presence is necessary, because it increases the efficiency of use of the device. By setting the cleaning time, the user can do other things while the device is working on cleaning parts.
5. Rinsing is not found in many models, but it is desirable that such an option is present, because after the main cleaning, the solution remains on the parts and it is advisable to remove it immediately while they are in the heated state.
6. On / off automation increases the cost of the product, but it also extends the period of maximum use. Each device is meticulously related to the solutions used and has individual instructions for safe use.

If you want to use the product for a long time, but are afraid of accidentally damaging certain functions due to the use of an incorrectly prepared solution, for example, using unfiltered water, then it is better to choose a device with automatic shutdown.
