The present situation and future of laser cleaning industry
Laser cleaning is to use a narrow pulse width, high power density laser to act on the surface of the object to be cleaned. Under the combined action of rapid light vibration, vaporization, decomposition and plasma peeling mechanism, the dirt can be separated from the substrate to achieve surface cleaning. At present, there are three typical laser cleaning methods: laser ablation cleaning, liquid film assisted laser cleaning and laser shock wave cleaning. Among the above three methods, the laser ablation cleaning method has the advantages of simple operation conditions and the most extensive use. Choosing the appropriate laser type and adopting optimized process parameters can remove various coatings, paints, particles or dirt. Although the other two methods have their own advantages, their application is still in the research stage, and there is no large-scale promotion
Laser cleaning machine is generally composed of laser, beam shaping unit, automatic control operation system, cleaning quality detection and protection unit, displacement platform, etc

application area
The research of laser cleaning technology started in the mid-1980s, but it didn't really enter into industrial production until the early 1990s. It has been well applied in mold cleaning, material surface treatment, large equipment and precision machinery, etc. In addition, European countries generally retain a large number of historical relics and ancient buildings. Many churches, castles, universities, museums, sculptures, etc. have a history of hundreds or even thousands of years. Europeans attach great importance to the protection and restoration of these "antiques". Since the mid-1990s, laser cleaning technology has been used in the restoration and decontamination of cultural relics.
