FAQ:

Q: What’s the ultrasonic cleaning principle?

A:The mechanism of ultrasonic cleaning is to use the physical effects such as cavitation, radiation pressure and sound flow when the ultrasonic wave propagates in the cleaning liquid, to peel off the mechanical phenomenon generated by the dirt on the cleaning member, and at the same time to promote the chemical reaction between the cleaning liquid and the dirt. Reaction, to achieve the purpose of cleaning the object. Ultrasonic cleaning is used more and more widely in various industries, agriculture, household equipment, electronics, automotive, rubber, printing, aircraft, food, hospital and medical research.

Q: What’s the difference on the frequency?

A: The frequency of the transducer is inversely proportional to the wavelength, and the size of the wavelength is related to the size of the bubble diameter (strictly speaking, due to the long time of nucleation at low frequency), while the diameter of the bubble is related to its explosion pressure. The higher the frequency, the smaller the wavelength, the smaller the diameter of the cavity and the lower the explosion pressure, but the higher the density of the cavity, the better the permeability.

 

When using organic solvents, usually first heat the cleaning agent to make it boil steam, the workpiece into the cleaning machine steam area, the cold workpiece encountered steam to produce condensation fog, and with the workpiece surface dirt has a role, as the drops fall and take away the dirt; Then the workpiece is immersed in the ultrasonic cleaning cylinder, through the strong ultrasonic cavitation for the second cleaning; Then use distilled clean cleaning fluid to spray and wash away the residual dirt on the surface; Finally, the workpiece is left in the steam zone for drying. Ultrasonic gas phase cleaning USES organic solvent as cleaning fluid.

 

Ultrasound can be divided into three kinds: infrasound, sound and ultrasound. The frequency of infrasound is below 20 Hz, the frequency of sound wave is between 20 Hz and 20 kHz, and the frequency of ultrasound is above 20 kHz. Infrasound and ultrasound are not audible to the human ear. Because of its high frequency and short wavelength, the ultrasonic wave has good direction and penetration ability, which is why the ultrasonic cleaning machine is designed and manufactured.

 

Cavitation: Cavitation is the transmission of ultrasonic waves to liquids by means of high frequency conversion of compression force and pressure reduction interaction more than 20,000 times per second. In the process of pressure reduction, vacuum nucleus bubbles are produced in the liquid. Under the compressive force, the vacuum nucleus bubbles will produce strong impact force when crushed under pressure, which will peel off the dirt on the surface of the cleaned products, so as to achieve the purpose of precise cleaning.
