A. cleaning medium:
Using ultrasonic cleaning, generally there are two kinds of detergent: organic cleaning agent (i.e., chemical solvent) and water-based cleaning agent. Cleaning medium is chemistry, and ultrasonic cleaning is a physical function, two kinds of effect, the combination of objects to fully and thoroughly clean.
B. power density:
, the higher the power density of the ultrasonic cavitation effect is stronger, the faster, the better cleaning effect. List for the high precision, surface roughness of the object, adopts the high power density of cleaning for a long time will have "cavitation corrosion on the surface.
C. the ultrasonic frequency:
Ultrasonic frequency is lower, the easier to produce cavitation in the liquid, has the stronger. High frequency ultrasonic directionality is strong, suitable for cleaning fine object.
D. clean environment:
Generally speaking, ultrasonic in 30 ℃ to 40 ℃ cavitation effect is best. Cleaner, the higher the temperature, the more significant role. Normally when the actual application of ultrasonic cleaning, adopt the working temperature of 30 ℃ ~ 60 ℃.
"Empty" (cavitation) phenomenon, also known as the "hole" phenomenon. High speed movement, when the object in the water in the crossroads of solid and liquid surface, pressure will reduce greatly, sometimes even close vacuum negative pressure, at this time, even under normal temperature, local water will boil, tiny air bubbles to form low pressure (20 ℃ in 0.02 under the atmospheric pressure, the water will boil). In under the action of water pressure around the bubbles collapse, sharply and associated powerful shock waves. 'that is' cavitation phenomenon.
