Laser cleaning is a cleaning method that is different from the traditional cleaning industry. It relies on the characteristics of the light pulses generated by the laser and is based on the photophysical reaction caused by the interaction between the high-intensity beam, short-pulse laser and the pollution layer. The traditional cleaning industry mostly uses chemicals and mechanical methods for cleaning. Today, as environmental protection regulations become more and more stringent and people awareness of environmental protection and safety is increasing, the types of chemicals that can be used in industrial production cleaning are becoming fewer and fewer. Laser cleaning has the characteristics of non-abrasive, non-contact, and no thermal effects. It is suitable for objects of various materials. It solves the problems of traditional cleaning methods that easily cause pollution and damages the environment. It is considered to be a reliable and efficient industrial cleaning solution.
