About the characteristics and introduction of laser-cleaning

The light beam emitted by the laser is absorbed by the contaminant layer on the surface to be treated. The absorption of large energy forms a rapidly expanding plasma, generating shock waves. The shock wave turns the contaminants into fragments and is removed. Compared with traditional cleaning methods such as mechanical friction cleaning, chemical corrosion cleaning, liquid and solid strong impact cleaning, and high-frequency ultrasonic cleaning, laser-cleaning has five obvious advantages:

Environmental protection advantages: laser-cleaning is a "green" cleaning method. It does not need to use any chemicals and cleaning fluids. The cleaned waste is basically solid powder, small in size, easy to store, recyclable, no photochemical reaction, no Will produce pollution. It can easily solve the environmental pollution problem caused by chemical cleaning. Often a single exhaust fan can solve the problem of waste generated by cleaning.

Effect advantage: The traditional cleaning method is often contact cleaning, which has 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. Grinding and non-contact, no thermal effect will not damage the substrate, so that these problems can be easily solved.

Control advantages: The laser can be transmitted through optical fibers, cooperate with robots and robots to easily realize remote operation, and can clean parts that are not easily reached by traditional methods. This can ensure the safety of personnel when used in some dangerous places.

Convenient advantage: Laser cleaning can remove various types of contaminants on the surface of various materials to achieve a cleanliness that cannot be achieved by conventional cleaning. It can also selectively clean the contaminants on the surface of the material without damaging the surface of the material.

Cost advantages: laser-cleaning is fast, efficient, and time-saving; although the initial one-time investment is relatively high when purchasing a laser-cleaning system, the cleaning system can be used stably for a long time, with low operating costs, and more importantly, it can be easily automated.
