Shop primer coating layer removal method using Q-switching fiber laser

摘要

Q-, which is an eco-friendly dry surface treatment method using a fiber laser, that removes the shop primer coating, which is a temporary rust-preventing paint applied to ships and offshore plants, to ensure a suitable surface condition for the surface to be coated without scattering dust and waste abrasives. It relates to a method for removing a shop primer coating film using a switching fiber laser, wherein a Q-switching fiber laser is irradiated under the conditions of 1064 nm wavelength, 7.9 ~ 13.2 J/cm2 laser energy density, pulse overlap rate of 70%, and pass overlap rate of 0%. Remove the shop primer coating, which is a rust-preventing paint.
