Laser cleaning technology refers to the process of using high-power density laser beam to irradiate the surface of the workpiece, so that the dirt, rust spots or coatings on the surface evaporate or peel off instantly, so as to achieve cleaning and purification. Laser cleaning equipment is a new generation of high-tech products with green surface treatment solution, which is easy to install, easy to operate and can realize automation production. It can be cleaned without chemical reagent, medium, dust and water by connecting the power supply. It can remove the resin, paint, oil stain, stain, dirt, rust, coating, coating and oxide layer on the surface of the object.
