First, the principle of ultrasonic cleaning ultrasonic cleaning genus
physical cleaning, the cleaning liquid into the tank, in the ultrasonic bath. Since the ultrasonic wave is a dense vibration wave like the sound wave, the pressure of the medium alternates during the propagation process. In the negative pressure region, a force of tearing is generated in the liquid, and a bubble of vacuum is formed. When the sound pressure reaches a certain value, the bubble rapidly grows, and in the positive pressure region, the bubble is crushed and closed due to the pressure. At this time, the liquid collides with each other to generate a strong shock wave. Although the displacement and speed are very small, the acceleration is very large, and the partial pressure can reach several thousand atmospheres. This is the so-called cavitation effect.
Second, several factors affecting the cleaning effect
1. Relationship with frequency: The lower the general frequency, the more obvious the cavitation effect, but the noise is relatively high, which is suitable for objects with relatively flat surfaces. The higher the frequency, the worse the cavitation effect, but the noise is relatively low, which is suitable for objects and electronic crystals with many micro-hole blind holes.
2, related to temperature: generally 30 ° C -50 ° C medium temperature cleaning effect is good.
3, related to sound intensity: according to the frequency, the sound intensity is generally selected at about 1-2w/cm2.
4, related to the cleaning solution: In general, the lower the viscosity of the cleaning solution, the higher the gas content, the better the cleaning effect.
5. It is related to the depth of the cleaning liquid and the position of the object to be cleaned.
Third, the application of ultrasonic cleaning in various fields
Because ultrasonic cleaning itself has unparalleled superiority in other physical cleaning or chemical cleaning, it is widely used in many fields such as service industry, electronics industry, pharmaceutical industry, laboratory, machinery industry, hard alloy industry, chemical industry, etc. A brief introduction to individual industries.
1. Application in the service industry.
In daily production, glasses and jewelry can be cleaned with ultrasonic waves. It is fast and harmless. Large hotels and restaurants use it to clean tableware. It not only has good cleaning effect, but also has the effect of killing viruses.
2. The application of ultrasonic in the micro-powder industry is well known. To obtain particles of different sizes, the crushed material is ground in a ball mill and sieved through layers of different specifications. After the sieve is used for a long time, the sieve hole will be blocked (such as diamond sieve). Brushing by other methods will destroy the sieve, and the effect is not satisfactory. After many manufacturers' tests, ultrasonic cleaning will not damage the sieve but also the sieve. The blocked particles are completely recovered.
3. Ultrasonic application in the pharmaceutical industry Ultrasonic cleaning technology has been widely used in many pharmaceutical companies, especially for the cleaning of vials, oral liquid bottles, ampoules, large infusion bottles, and butyl rubber stoppers and natural rubber stoppers. The cleaning aspect has been approved. For the cleaning of bottles, ultrasonic cleaning technology is used to replace the original brushing machine, which is realized by the processes of inverted water injection, ultrasonic cleaning, internal and external washing, air drying, and turning.
4, ultrasonic cleaning of the filter element We know that no matter what kind of filter or filter of any kind, after a period of use, the permeability will be reduced due to impurities and scrapped, the average filter price is lower However, for the chemical fiber industry, an imported filter element, the price is nearly 10,000 yuan, it is a pity to abandon it. The ultrasonic filter cleaning machine developed by us in cooperation with other scientific research units uses a concentrating ultrasonic cleaning machine, which can concentrate more than 1KW of energy. On the radiation surface of 200×20mm2, the ultrasonic intensity is large, the plug can be quickly removed, and the equipment adopts the anti-filter device. As long as you provide the core, we can provide you with a complete cleaning device. (The equipment takes 10-15 minutes to wash a filter element). Applicable to PP cotton filter, activated carbon filter, hollow fiber filter ceramic membrane filter.
5, ultrasonic cleaning of metal is well known, after the metal bar is extruded into a wire, the outside of the wire often has a layer of carbonized film and oil, with acid cleaning or other cleaning methods, it is difficult to remove dirt (especially the whole wire ), ultrasonic washing machine is a continuous wire, designed according to the actual production needs, high-efficiency cleaning equipment, the rough washing part consists of cleaning fluid storage tank, transducer, circulation pump, filter and supporting piping system, wire After ultrasonic cleaning and fine washing, it is blown dry to complete the entire cleaning process. The whole set of equipment integrated control is simple, convenient and effective. It is widely used in other wires such as silk, tungsten wire, molybdenum wire, silk wire and copper wire (before insulation coating).
6. Application of ultrasonic cleaning technology in phosphating treatment The pre-spraying treatment process is very important. The general traditional process uses acid to treat the workpiece, which is heavy on the environment and poor in working environment. At the same time, the disadvantage of Zui is Residual acid after pickling and rust removal of complex structural parts is difficult to rinse. After the workpiece is sprayed, the time is not long, and rusting occurs along the crack, which damages the surface of the coating and seriously affects the appearance and internal quality of the product. Ultrasonic cleaning technology is applied to the pre-painting treatment, which not only can quickly peel off the dirt on the surface and the gap of the object, but also the coating layer of the coating is firm and does not return to rust.
Ultrasonic cleaning is available in all walks of life. The above are only representative industrial applications, and many new industries and fields can use ultrasonic cleaning. We look forward to the joint development and exploration by the majority of users and manufacturers.
