    3.2L Ultrasonic Cleaner Applications

    Ultrasonic Cleaner Comparison Before and After Cleaning

    Tips: What Affects the Cleaning Effect of Ultrasonic Cleaner?

    1. Cleaning medium
    With ultrasonic cleaning, there are generally two kinds of cleaning agents, namely chemical solvent and water-based cleaning agent. The chemical action of cleaning medium can accelerate ultrasonic cleaning effect. Ultrasonic cleaning is a physical action. The combination of two kinds of action can fully clean the objects.

    2. Power density
    The higher the power density of ultrasonic wave, the stronger the cavitation effect, the faster the speed, the better the cleaning effect. However, for the precise product with high degree of finish, it will cause cavitation, corrosion on the surface of the object if using a long time high power density cleaning.

    3. Ultrasonic frequency
    Low frequency ultrasonic cleaner is suitable for roughly cleaning the workpiece, while high frequency ultrasonic cleaning machine has strong ultrasonic direction, suitable for fine cleaning of objects.

    4. High temperature
    Generally speaking, the cavitation effect of ultrasonic wave is the best in 50°C~60°C. The cleaning agent is not always more effective with higher temperature, and may fail at high temperature. Usually in more than 85°C, cleaning effect has become poor. So the actual application of ultrasonic cleaning, the operating temperature of 50°C~70°C is used.
