Technical characteristics of ultrasonic cleaning machine
The cleaning effect is good, the cleanliness is high, and the cleanliness of all workpieces is consistent. The cleaning speed is fast, the production efficiency is improved, and it is safe and reliable without manual contact with the cleaning fluid. It can also be used to clean the deep hole, slit and concealed part of workpiece. No damage to the surface of the workpiece, saving solvent, heat energy, working site and labor.
The ultrasonic cleaning method is more than the conventional cleaning method, especially the surface of the workpiece is more complex, such as some mechanical parts with uneven surface and blind holes, and some small products with high requirements for cleanliness, such as clocks, watches and precision machinery parts, electronic components, circuit board components, etc., can achieve ideal results by using ultrasonic cleaning.
The mechanism of ultrasonic cleaning mainly includes the following aspects: a strong shock wave is generated when cavitation bubbles are broken, and part of the dirt layer is peeled off, dispersed, emulsified and detached under the action of shock wave.
Because the air bubbles produced by cavitation phenomenon penetrate into the gap and gap between the dirt layer and the surface layer formed by impact. Due to the synchronous expansion and contraction of the small bubbles and the sound pressure, the physical force like peeling repeatedly acts on the dirt layer, and the dirt layer is peeled off layer by layer, and the bubbles continue to penetrate into it until the dirt layer is completely stripped. This is the secondary effect of cavitation. The impact of ultrasonic vibration of cleaning fluid on dirt in ultrasonic cleaning. Ultrasound accelerates the dissolving process of chemical cleaning agent to the dirt, and the combination of chemical force and physical force accelerates the cleaning process.
