      The ultrasonic wave propagates in the liquid, so that the liquid and the cleaning tank vibrate together at the ultrasonic frequency. When the liquid and the cleaning tank vibrate, they have their own natural frequency. This vibration frequency is the frequency of the sound wave, so people hear the buzzing Voice. With the continuous development of the cleaning industry, more and more industries and enterprises have used ultrasonic cleaning machines.

      For the principle of ultrasonic cleaning machine, the high-frequency oscillation signal sent by the ultrasonic generator is converted into high-frequency mechanical oscillation by the transducer and propagated to the medium-cleaning solvent, and the ultrasonic wave is dispersed in the cleaning solution. The forward radiation between dense phases makes the liquid flow and produces tens of thousands of tiny bubbles with a diameter of 50-500 μm. The tiny bubbles in the liquid vibrate under the action of the sound field. These bubbles form and grow in the negative pressure area where ultrasonic waves propagate longitudinally, while in the positive pressure area, when the sound pressure reaches a certain value, the bubbles rapidly increase and then close suddenly. And when the bubble is closed, a shock wave is generated, and thousands of atmospheres are generated around it, which destroys the insoluble dirt and makes them dispersed in the cleaning liquid. Particles and detachment, so as to achieve the purpose of cleaning parts. In this process known as the "cavitation" effect, bubble closure can result in high temperatures of several hundred degrees and instantaneous high pressures of over 1,000 air pressures.

      The advantages of the ultrasonic cleaning machine are: the ultrasonic cleaning effect is good and the operation is simple. The sound that people hear is a sound wave signal with a frequency of 20-20000Hz, and the sound wave higher than 20000Hz is called ultrasonic wave. One reason is that there is a local tensile stress in the liquid to form a negative pressure. The reduction of the pressure makes the gas originally dissolved in the liquid supersaturated, and escapes from the liquid to become small bubbles; the other reason is that the strong tensile stress tears the liquid. Open " into a void, called cavitation.

      Use

      1. Household application: daily use items such as gold and silver jewelry, jewelry, headwear, brooches, glasses, watch chains, water pens, CDs, razors, combs, toothbrushes, dentures, tea sets, etc., as well as feeding bottles, teats and fruits such as grapes, cherries , strawberries, these accessories, tools and fruits are also disinfected and sterilized while being washed. In addition, ultrasonic waves can be used for beauty and skin care on the hands. Long-term use can keep the skin tender, smooth and elastic.

      2. Glasses and optical instruments: All optical lenses, such as various glasses, magnifying glasses, telescopes, microscopes, cameras, video cameras and other lens parts, are cleaned by ultrasonic waves, and all conditions are fully revealed.

      3. Jade and accessories processing industry: In the process of grinding and polishing, a large amount of dust and dirt will adhere to jade and accessories, and these workpieces often have complex shapes and many gaps, and traditional cleaning methods are often ineffective. The washer is unique.

      4. Clocks and precision instruments: With the Kangdao ultrasonic cleaner, clocks and precision instruments are free from the trouble of disassembling and assembling screws, gears, hairsprings, bracelets, etc. one by one. Such as gasoline) in the cleaning tank, you can get twice the result with half the effort.

      5. Banking, office, finance, arts and crafts, advertising industry, office supplies: such as printers, nozzles, stylus pens, pens, brushes, nozzles, and sprayers are often blocked, and seals are often blurred due to the adhesion of ink pads. The special ultrasonic cleaner can keep the flow and clear. If combined with an appropriate amount of detergent or other cleaning agents, it will have better results.

      6. Maintenance of communication equipment and electrical appliances: The precise circuit boards and spare parts of mobile phones, walkie-talkies, walkmans and other electrical appliances can be cleaned with Kangdao ultrasonic cleaning machine combined with anhydrous alcohol, which can obtain excellent dust-free and pollution-free cleaning results.

      7. Medical units, colleges and universities: cleaning of various medical instruments such as surgical instruments, dental dentures, dental molds, sight glasses, beakers and test tubes for laboratory experiments, etc. Cleanliness, accelerated chemical reactions and reduced time.
