On the one hand and destroy the dirt cleaning a surface, on the other hand can cause fatigue damage and dirt layer was transferred from the gas bubble type, vibration scrubbing on solid surface pollution layer once the seam can be drilled, bubble immediately drill down vibration causes the pollution layer off, because the air into use, two kinds of liquid in the interface rapidly dispersed and emulsified oil, when the solid particles wrapped and adhered to the surface cleaning, oil emulsion, solid particles to fall off, ultrasonic propagation in cleaning liquid will produce positive and negative alternating pressure, jet formation, impact cleaning, at the same time, due to the nonlinear effect will produce acoustic streaming and micro sound flow, and ultrasonic cavitation will produce high-speed micro jets in the solid and liquid interface, all these effects can destroy the dirt, remove or weaken the boundary pollution layer, increasing the stirring and diffusion effect, accelerated soluble The dissolution of the nature of the dirt, strengthen the cleaning effect of chemical cleaning agent. It can be seen that the liquid can be immersed in the presence of the sound field and there is the role of cleaning, which is suitable for the characteristics of the surface is very complex parts of the cleaning. In particular, the use of this technology can reduce the amount of chemical solvents, thereby greatly reducing environmental pollution.
