Oil painting, painting on metal surface to cleaning by pulse laser cleaning machine

Pulse laser cleaning machine test remove: painting on metal surface

Brief introdution:

1. Phosgenation/Photolysis

The laser generated by the laser can be concentrated by the optical system to achieve a high concentration of energy. The focused laser beam can generate a high temperature of several thousand degrees or even tens of thousands of degrees near the focal point, which will instantly vaporize or decompose the attachments on the surface of the object.

2. Light peeling

Through the action of the laser, the attachments on the surface of the object are heated and expanded. When the expansion force of the attachments on the surface of the object is greater than the adsorption force between it and the substrate, the attachments on the surface of the object will be detached from the surface of the object.
