In recent years, with the increasing awareness of environmental protection, the development of the cleaning industry around the world has brought enormous challenges. Various cleaning technologies that are conducive to environmental protection have emerged. Laser cleaning technology is one of them. The so-called laser cleaning technology refers to the use of a high-energy laser beam to illuminate the surface of the workpiece, so that the surface of the dirt, rust or coating is instantaneously evaporated or peeled off, and the surface attachment or surface coating of the cleaning object is removed at high speed, thereby achieving a clean process. . It is a new technology based on the interaction between laser and matter. Unlike traditional mechanical cleaning, chemical cleaning and ultrasonic cleaning (wet cleaning), it does not require any CFC-based organic solvents that destroy the ozone layer. , no noise, harmless to the human body and the environment, is a "green" cleaning technology. Compared with traditional cleaning methods such as mechanical cleaning, chemical cleaning, liquid solid impact cleaning, and high-frequency ultrasonic cleaning, laser cleaning has obvious advantages. It is efficient, fast, low cost, low heat load and mechanical load on the substrate, cleaning is non-injury; waste can be recycled, no environmental pollution; safe and reliable, does not damage the health of operators; can remove various thicknesses and different The coating of the ingredients; the cleaning process is easy to achieve automatic control, enabling remote remote cleaning.
