Ultrasonic cleaning is to make use of the cavitation action of ultrasonic wave in liquid, acceleration action and direct flow effect on liquid and sewage directly and indirectly, so that the sewage layer is dispersed, emulsified and stripped to achieve the purpose of cleaning. Cavitation and direct flow are more widely used in ultrasonic cleaning machines.
The mechanism of ultrasonic cleaning mainly includes the following aspects: a part of the dirt layer is stripped off, dispersed, emulsified and shedded because of the strong shock wave produced when the cavitation bubble burst. Because of the cavitation phenomenon, the bubble, the gap between the dirt layer and the surface layer formed by the impact, and the void permeate, because the small bubble and the sound pressure expand simultaneously, shrink, and the physical force, like peeling, acts repeatedly on the dirt layer. Layers of dirt are stripped and bubbles continue to infiltrate until the layer is completely stripped. This is the secondary effect of cavitation. Impact of ultrasonic vibration on dirt in ultrasonic cleaning. Ultrasonic acceleration Study cleaning agent (RT-808 ultrasonic cleaning agent) the dissolution process of dirt, chemical and physical forces combined to accelerate the cleaning process.
Ultrasonic cleaning is more common than conventional cleaning methods, especially when the surface of the workpiece is more complicated, such as some mechanical parts with uneven surface and blind holes. Some particularly small products with high cleanliness requirements such as clocks and precision machinery parts, electronic components, circuit board components, and so on, the use of ultrasonic cleaning can achieve a very good effect. The principle of ultrasonic cleaning is that the signal of high frequency oscillation issued by ultrasonic generator is transmitted to the media-cleaning solvent through the conversion of the transducer into high frequency mechanical oscillation. The ultrasonic wave has the same forward radiation in the cleaning liquid. To cause the flow of liquids to produce tens of thousands of tiny pieces bubbles.
These bubbles form and grow in the negative pressure region of ultrasonic wave propagation longitudinally, but close rapidly in the barotropic region. In this process, known as the "cavitation" effect, the closure of a bubble can form an instantaneous high pressure of more than 1000 atmospheres, resulting continuously in instantaneous high pressure, like a series of small "explosions" that continually impact the surface of an object. The dirt in the surface and crevice of the object is rapidly peeled off, so as to purify the surface of the object.
