Abstract

In this paper, temperature change and removal depth of continuous laser removal of various coatings (alkyd paint, epoxy varnish, epoxy primer) were analyzed by finite element simulation software. The simulation results show that under the condition of continuous laser irradiation for 1 s, the optimal cleaning threshold of double-layer structure target composed of epoxy primer and epoxy varnish is 200 W/mm², and the optimal cleaning threshold of three-layer structure target composed of epoxy primer, epoxy varnish and alkyd paint is 150 W/mm². The reason for this phenomenon is explained by the different material properties of each layer of coating. At the same time, it is concluded that the temperature when the laser directly acts on the double-layer target is lower than that when the laser acts on the three-layer target, which is conducted by alkyd coating. The results achieved in this paper can provide a feasible process parameter for related industries.
