ultrasonic cleaner have you heard of the name, but how much do you know about the working principle of the ultrasonic cleaner? Understanding the working principle before proceeding with the next operation is extremely crucial. Ultrasonic cleaning utilizes the deceleration effect, cavitation effect and direct flow effect of ultrasonic waves in liquids to indirectly and directly act on the liquid and contaminants, causing the contaminant layer to be dispersed, emulsified and stripped, thereby achieving the cleaning purpose.
