High-frequency ultrasonic cleaning machine more suitable for cleaning what items?

During the operation of the ultrasonic cleaning machine, the high-frequency oscillating signal, which is generated by the ultrasonic generator, is spread into the medium cleaning organic solvent according to the conversion of the transducer into the high-frequency mechanical oscillating signal, the ultrasonic wave radiates forward in the cleaning liquid, which makes the liquid flow and there are countless tiny bubbles with diameter of 50-500μm.

Ultrasonic cleaning machine in the longitudinal transmission of negative pressure zone caused, growth, but in the positive pressure zone, when the sound pressure reached a specified set value, bubble rapidly increased, suddenly closed. And when the bubble closes, there's a shock wave, which creates thousands of atmospheres around it, damaging the insoluble dirt and causing it to disperse in the cleaning fluid. When the particles are coated in oil and adhere to the surface of the cleaning piece, the oil is emulsified and the solid particles are peeled off to achieve the effect of cleaning the parts. In a process known as "Cavitation," bubble closure can create hundreds of Baidu temperatures and instantaneous high pressures of more than 1,000 atmospheres.

The cleaning effect of ultrasonic cleaning machine is remarkable and the operation is simple. The sound you hear is a 20-to 20,000-hertz sound wave, and anything above that is called an ultrasonic wave, which travels vertically along a sinusoidal curve, creating a lot of tiny bubbles. One of the main reasons is that negative pressure appears due to the local tensile stress in the liquid, which makes the dissolved gas supersaturate and overflow from the liquid Another major reason is that a strong tensile stress"Tears" a liquid into a cavity called cavitation.

The grinding of ultrasonic cleaning machine is the main process which affects the processing efficiency and surface quality of optical mirror glass,

the source of pollutants in the grinding process is grinding powder and asphalt, a few enterprises will appear in the production process of paint chips. The types of powders used are different and are usually Cerium(IV) oxide alkali oxides. According to the lens material grinding accuracy is not the same, select the right type of grinding powder.

The bitumen commonly used in the grinding process is protective to avoid scratches or corrosion of the finished mirror. The cleaning equipment after grinding is mainly divided into two kinds: one mainly uses organic solvent cleaning agent, the other mainly uses semi-water-based cleaning agent.
