The cross-sectional view of the laser paint residue removal is just the opposite of the light intensity distribution shape trend we see. This is because the heat generated by the strong light distribution is much higher than the weak light, so our experimental results are consistent with our recursive algorithm. The results of the simulation analysis are consistent. The experiment shows that our paint effect is not only mainly affected by the laser output energy density, but also by the quality of the laser beam output by our laser, which is determined by the laser parameters we use.
Studies have shown that the paint removal effect of using Q-switched lasers is better than other types of lasers without considering the damage of the matrix. The chemical composition of the paint is generally natural resin (such as rosin) modified by drying oil or semi-drying oil, man-made resins, synthetic resins, such as methyl methacrylate, polyurethane, polystyrene, polyvinyl chloride and etc. There are many types of pigments and solvents that cannot be specifically defined. In addition, the wide use of additives increased the complexity of the paint composition. Therefore, different types of paints have different compositions, and their thermophysical parameters and optical characteristics are quite different, which leads to the required paint removal threshold. The value is different, which is fully reflected in our analysis, calculation simulation and experimental results. During the laser paint removal process, the laser acts on the paint coating and the paint coating absorbs laser energy, converts it into the heat energy making the temperature of the paint reach its vaporization temperature in a very short time so as to achieve our paint removal effect. This is in our paint removal experiment, which is after the laser completely removes the paint coating on the stainless steel substrate. We are on the test bench No paint particles were found on the above, further verifying that the aforementioned paint absorbs energy and converts it into heat. The final temperature is too high and then it vaporizes.
