Introduction to the characteristics of Laser-Cleaning

According to the analysis of a large number of experimental results, the laser-cleaning mechanism is different according to the difference between the surface attachment and the thermal physical parameters of the matrix. When the thermal physical parameters of the surface attachment and the matrix material are quite different, the laser-cleaning mechanism includes: ablation vaporization, thermal vibration and thermal shock mechanism, and acoustic vibration mechanism, such as laser-cleaning paint and rubber layers. Compared with the traditional cleaning process, laser-cleaning technology has the following characteristics:

1. It is a kind of "dry" cleaning, no cleaning fluid or other chemical solutions are needed, and the cleanliness is much higher than that of chemical cleaning processes;

2. The scope of dirt removal and the scope of applicable substrates are very wide;

3. By adjusting the laser process parameters, it is possible to effectively remove contaminants without damaging the surface of the substrate, so that the surface is as old as new;

4. Laser-cleaning can easily realize automatic operation;

5. The laser decontamination equipment can be used for a long time, and the operating cost is low;

6. Laser-cleaning technology is a "green" cleaning process. The eliminated waste is solid powder, small in size, easy to store, and basically does not pollute the environment.
