Compared with a variety of other cleaning methods, ultrasonic cleaning machine has shown great superiority. Especially in the specialized, group production enterprises, has gradually used ultrasonic cleaning machine to replace 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 sound waves in the medium when the transmission of the penetrating and cavitation shock wave. So it is easy to with a complex shape, cavity and fine hollow parts clean, the general process of oil removal, rust prevention, phosphating, etc., under the action of ultrasound can be completed in just two or three minutes, its speed than traditional methods can be increased by several times to dozens of times, cleanliness can also reach high standards, which in many of the product surface quality and productivity requirements of high occasions, more prominently displayed with other processing methods difficult to achieve or irreplaceable results.
Its advantages are summarized as follows.
(1) cleaning speed, good cleaning effect, high cleanliness, consistent workpiece cleanliness, no damage to the surface of the workpiece.
(2) does not require manual contact with the cleaning fluid, safe and reliable for deep holes, slits and hidden parts of the workpiece also clean.
(3) Save solvent, heat energy, workplace and labor.
(4) High cleaning accuracy, can powerfully clean the tiny stain particles.
Factors affecting cleaning effect.
Cleaning medium
Using ultrasonic cleaning, there are generally two types of cleaning agents, namely chemical solvents and water. The chemical effect of cleaning medium can accelerate the effect of ultrasonic cleaning, ultrasonic cleaning is a physical effect, the combination of the two effects, according to the object for full and thorough cleaning.
Power density
The higher the power density of ultrasound, the stronger the cavitation effect, the faster the speed, the better the cleaning effect, but for the precision of the surface finish is very high objects, using a long time of high power density cleaning will produce cavitation, corrosion on the surface of the object.
Ultrasonic frequency
The lower the ultrasonic frequency, the easier the cavitation produced in the liquid, the stronger the force produced, the stronger the effect, suitable for workpiece coarse, dirty, initial washing, high frequency is ultrasonic directional, suitable for fine object cleaning.
Cleaning high temperature
Ultrasonic cavitation in 50 ° C ~ 60 ° C when the best effect, the cleaner is not the higher the temperature, the more significant the role, there may be high temperature failure, usually ultrasonic in more than 85 ° C, the cleaning effect has become worse. So the actual application of ultrasonic cleaning, the use of 50 ° C ~ 70 ° C working temperature.
