1. Méthode de nettoyage à sec au laser. Le laser éclaire directement la surface de l'objet, et après avoir contaminé les particules ou la surface absorbe de l'énergie, les particules sont séparées de la surface par diffusion thermique, photolyse, gazéification, etc.
2. Méthode de nettoyage humide au laser. Vaporisez du liquide non polluant (principalement de l'eau, parfois de l'alcool) on the surface of the material to be cleaned, and then irradiate it with laser. After the liquid medium absorbs the laser energy, it will explode and vaporize, and push the surrounding polluted particles away from the surface of the material. . In addition, a so-called laser duplex cleaning method has been proposed. The laser energy is absorbed by the substrate material, and then the condensed intermediate medium is heated by heat convection, and the intermediate medium is explosively vaporized. Under the promotion of high airflow, the particles are separated from the substrate surface together with the intermediate medium.
3 Laser + méthode du gaz inerte, C'est, while irradiating the laser, the inert gas is blown to the surface of the substrate. Lorsque la saleté est décollée de la surface, il sera immédiatement expulsé de la surface par le gaz pour éviter la recontamination et l'oxydation de la surface; After loosening, clean with non-corrosive chemical methods.
