Cleaning mode and charateristics:

      Cleaning means eliminating pollutant, liquid and solid, on the surface of the workpieces, so as to make the surface reach certain cleanliness factor. Cleaning process is reciprocity among cleaning medium, pollutant and workpiece's surface. It is a complicated process containing physical change and chemical change. Cleaning is not only related with the character, kind, form and coherent degree of pollutant, it is related with physical character, cleaning capability of cleaning medium and metarial, surface state of workpiece, it is also related with cleaning condition, such as: temperature, pressure and ultrasonic oscillation, mechanical force and so on. Therefore, choosing a reasonable cleaning mode is very important for cleaning result.
