Factors affecting ultrasonic cleaning
Cleaning medium: Ultrasonic cleaning, generally there are two types of cleaning agents, namely chemical solvents and water-based cleaning agents. The chemical action of the cleaning medium can accelerate the ultrasonic cleaning effect, the ultrasonic cleaning is a physical action, and the two functions are combined to perform sufficient and thorough cleaning according to the object.
Power density: The higher the power density of the ultrasonic wave, the stronger the cavitation effect, the faster the speed, the better the cleaning effect, but for the object with high surface smoothness, using a long time high power density cleaning will empty the surface of the object. Chemical, corrosion.
Ultrasonic frequency: The lower the ultrasonic frequency, the easier the cavitation in the liquid is, the stronger the force is, and the stronger the effect is. It is suitable for coarse, dirty and initial washing of the workpiece. The high frequency is strong for the direction of the ultrasonic, suitable for fine Object cleaning.
Cleaning high temperature: Generally speaking, the ultrasonic wave has the best cavitation effect at 50 ° C ~ 60 ° C, the cleaning agent is not the higher the temperature, the more significant the effect, there may be high temperature failure, usually when the ultrasonic wave exceeds 85 ° C The cleaning effect has deteriorated. Therefore, when the ultrasonic cleaning is actually applied, the operating temperature of 50 ° C to 70 ° C is used.
