Ultrasonic cleaning machine cleaning effect is not good how to do? What factors generally affect the cleaning effect of ultrasonic cleaning machine?
Five factors that affect the effect of ultrasonic cleaning.
1, power density: the higher the power density of ultrasound, the stronger the cavitation effect, the faster the speed, the better the cleaning effect, but for precision surface finish is very high objects, using a long time of high power density cleaning will produce cavitation, corrosion on the surface of the object, so we also need to properly select the power of the tank to do.
2, ultrasonic cleaning machine frequency: the lower the frequency, the better the cavitation, the higher the frequency, the better the refraction effect. For the simple surface should be used low frequency, for complex surfaces and deep holes blind holes should be used high frequency.
3, cleaning media: ultrasonic cleaning generally have two types of cleaning agents: chemical solvents and water-based cleaning agents. The chemical effect of the cleaning medium can accelerate the ultrasonic cleaning effect, ultrasonic cleaning is a physical effect, the combination of the two effects, according to the object for full and thorough cleaning, cleaning medium combined with the cavitation effect of ultrasound, will be able to adhere to the surface of the workpiece oil, impurities clean.
4, cleaning temperature: ultrasonic cavitation is better at 40 ℃ ~ 50 ℃. The higher the temperature, the more conducive to the decomposition of dirt, but when the temperature reaches 70 ℃ ~ 80 ℃ later, it will affect the role of ultrasound, reducing the cleaning effect.
5, cleaning time: the longer the cleaning time, the better the effect, except for special materials.
