1.high efficiency Under the action of high temperature energy, the deposits are instantly vaporized and evaporated off the surface of the object, and the time required is very short. The traditional cleaning methods, such as ultrasonic cleaning, can only be cleaned after preheating, cooling and other processes, which takes a long time. 2. greener Laser cleaning is a "green" cleaning method without the use of any chemicals and cleaning fluids. The cleaned wastes are basically solid powders, small in size, easy to store, recyclable, free of photochemical reactions, and no pollution. . It can easily solve the problem of environmental pollution caused by chemical cleaning. Often an exhaust fan can solve the problem of waste generated by cleaning. 3.low cost Laser cleaning is fast, efficient, and time-saving; although the initial one-time investment in purchasing a laser cleaning system is high, the cleaning system can be used stably for a long time, with low operating costs, and more importantly, it can be easily automated. 4.more convenient Laser cleaning can remove various types of contaminants on the surface of various materials, achieving a cleanliness that cannot be achieved by conventional cleaning. Furthermore, contaminants on the surface of the material can be selectively cleaned without damaging the surface of the material. 5.good effect The traditional cleaning method is often contact cleaning, which has a mechanical force on the surface of the cleaning object, damages the surface of the object or the cleaning medium adheres to the surface of the object to be cleaned, and cannot be removed, resulting in secondary pollution. The non-abrasive and non-contact, non-heating effects of laser cleaning do not damage the substrate, making these problems easy
