The laser cleaning technology refers to the use of high-energy laser beams to irradiate thesurface of the workpiece, so that the dirt, rust or coating on the surface.The layer evaporates or peels offinstantly, and effectively removes the surface attachment or surface coating of the cleaning object at high speed, thereby to achieve a clean process. It is a new technology based on the interaction effect between laser and matter,which is different from traditional mechanical cleaning method chemical cleaning method and ultrasonic cleaning method (wet cleaning process),it doesn't need any broken CFC organic solvents that deplete the ozonelayer, no pollution, no noise, no harm to the human body and the environment.
