1. Cleaning medium: ultrasonic cleaning, generally two types of cleaning agents: solvent, water-based cleaning agent, etc. 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 fully and thoroughly clean the object.
2. Power density: power density = transmission power (W) / emission area (cm2) is usually ≥ 0.3W / cm2, the higher the power density of the ultrasonic wave, the stronger the cavitation effect, the faster the speed, but for the cleaning effect, Not the bigger the better. Because for high precision, high surface finish, long-term high power density cleaning can cause "cavitation" corrosion on the surface of the object.
3. Ultrasonic frequency: ≥20KHz, can be divided into low frequency, intermediate frequency, high frequency 3 segments. The lower the ultrasonic frequency, the easier the cavitation generated in the liquid, the greater the force generated, and the stronger the effect, which is suitable for the initial washing of the workpiece (rough, dirty). The high frequency makes the ultrasonic direction strong, which is suitable for fine object cleaning.
4. Cleaning temperature: Generally speaking, the ultrasonic wave has the best cavitation effect at 30 °C - 40 °C. The higher the temperature of the cleaning agent, the more significant the effect. Generally, when ultrasonic waves are actually applied, an operating temperature of 50 ° C to 55 ° C is employed.
