Laser tsaftacewa iya shawo kan gajerun hanyoyin fasahar tsabtace gargajiya, kamar cin lokaci, aiki tukuru, gurbata muhalli, da sauransu, kuma suna taka muhimmiyar rawa wajen cire datti na ƙarfe. Kari akan haka, za'a iya yin amfani da tsabtace laser don ƙara ƙarfin ƙarfe don haka ana iya kiyaye ƙarfen da ke ƙarfe da ƙwaƙwalwa kuma ya samar da wata hanyar kariya tare da kauri daga 'yan ƙananan microns don hana ci gaba da lalata ƙarfe. Contarfafawa ta amfani da fasaha na tsabtace laser na iya sanya juriya na lalata kayan ƙarfe 3ara sau 3 zuwa 4.
2. Zaɓin nau'in Laser da raƙuman ruwa suna da tasiri mai mahimmanci akan tasirin tsabtatawa
As shown in the figure, the absorption coefficients of various metals change with wavelength. At λ=916nm-1200nm, most metals have higher absorption coefficients in this band, and organic matter has relatively strong laser absorption in this band. Because of this, in terms of absorption rate, combining the comparative advantages of various aspects, fiber lasers have demonstrated unique advantages in all aspects. The organic pollution layer absorbs the laser strongly, and the temperature of the organic pollution layer quickly rises to the evaporation point to vaporize, thereby achieving the purpose of removing the pollution layer without damaging the substrate. Then determine the energy threshold of laser cleaning, the energy threshold of laser cleaning will determine the effect of laser cleaning. Selecting the appropriate laser cleaning energy threshold requires comprehensive consideration of the material's performance, microstructure, morphological defects, and the effects of laser wavelength and pulse width.
