Principle of Ultrasonic Cleaning

One, Principle

    Ultra-wave cleaning principle is issued from the ultrasonic generator of high frequency oscillation signal, through the high-frequency transducer to convert mechanical vibration transmitted to the media, cleaning solvents, ultrasonic cleaning fluid density in the forward-and-white radiation, so that the liquid flow generated tens of thousands of tiny air bubbles, there are tiny bubbles in a liquid (cavitation nuclear) in the sound field under the effect of vibration, when the sound pressure level reaches a certain value, the bubbles rapidly, then suddenly closed, closed, when the bubble generate shock waves produced in their thousands around the atmospheric pressure, destruction of dirt makes them insoluble in the cleaning liquid dispersion, when the bodies wrapped in the adhesion of particles to oil in the washing of the surface, the oil is emulsified, solid particles that is out of , so as to achieve the purpose of cleaning the surface clean.

Ultrasonic two main parameters:

Frequency 20KHz ~ 120KHz

Power density = transmitter power (W) / emission area (CM2)

Two, ultrasonic cleaning effect and related data

   Cleaning Media: Using ultrasonic cleaning, generally have two types of cleaning agents, namely, chemical solvents and water-based cleaning agent. Cleaning medium can accelerate the chemical action effects of ultrasonic cleaning, ultrasonic cleaning is the physical role, combining two functions, to pairs of objects in full, thorough cleaning.

   Power density: the higher the power density ultrasonic cavitation effect is stronger, faster, better cleaning effect, but for high precision surface finish of the object, using a long period of high power density will clean the surface of the object space of, corrosion.

   Ultrasonic Frequency: ultrasonic frequency the lower the liquid cavitation generated more easily, resulting in a forceful, stronger role for the workpiece thick, dirty, the beginning of washing, the high-frequency ultrasonic directional strong, suitable for fine object cleaning.

   Cleaning temperature: In general, ultrasound in 30 ℃ ~ 40 ℃ when the cavitation effect of the best cleaning agent is the higher the temperature the more significant role, usually the practical application of ultrasonic cleaning, the use of 40 ℃ ~ 60 ℃ operating temperature.

Third, the advantages of ultrasonic cleaning

    Compared to many other methods of cleaning, ultrasonic cleaning machine has shown significant advantages, especially in the professional grouping of production enterprises, has been increasingly using ultrasonic cleaning machines replaced the traditional dipping, brushing, pressure washing, vibration cleaning and steam cleaning process methods, ultrasonic cleaning machine of high efficiency and high cleanliness, thanks to its acoustic wave propagation in the medium penetration and cavitation generated by the impact of chronic disease, so it is easy to with a complex shape, lumen and the thin air of the parts cleaned on general degreasing, rust, phosphating and other processes, in just 23 minutes under ultrasound can be done, its speed can increase several times than traditional methods, and even a few times, can also achieve high standards of cleanliness, which in many products require a higher surface quality and productivity of the occasion, but also has highlighted difficult to achieve with other treatment methods or non-replacement results.

Summarized its advantages are as follows:

* Cleaning effect is good, high cleanliness and cleanliness of all the parts in line.

* Cleaning speed, improve production efficiency.

* Do not need to manually clean contact with liquid, safe and reliable.

* The deep hole, slit, and the workpiece can be cleaned shelter.

* To save solvents, heat, work sites and labor and so on.

Four, application and scope of the industry

    Electronic, electrical, instruments, meters, machinery, hardware, tools, bearings, hydraulic, plating pre-treatment, medical, aviation, glass, glasses, watches, jewelry, ceramics, chemical fiber, pens. (For degreasing, dirt, wax, to carbon, to rust, to oxidation, phosphating and other cleaning agents.)
