1. Ko te horoi horoi he tango noa i te paru engari ka pai ake hoki te aukati
Te waatea i nga ngoikoretanga o te hangarau horoi tuuturu, penei i te waa-wa, te mahi-mahi, te whakakakahu i nga taiao, aha atu, me te whai waahi nui ki te tango i te paru o te whakarewa. Hei taapiri, ka taea te whakahaere i nga tohu horoi a laser kia purea ai te mata o te maitai ki te horoi me te hanga i tetahi papa paruru me te matotoru o nga kaireti hei aukati i te aukati o te whakarewa. Te whakakorea ma te whakamahi i te hangarau horoi laser ka taea te aukati i te whakakorenga o nga taputapu whakarewa Whakanuihia te 3 ki te 4 nga wa.
2. Ko te painga o te momo laser me te roangaru te awe mo te mea horoi
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.
3. Ko te koki mo te whakakii laser tika e whai hua ana ki te horoi
A, no te mea kua tupu te laser ki tetahi koki tuuturu, ka tiaho tonu te laser ki raro i nga matikiri taikaha, ka hua ake te taumahatanga thermoelastic teitei. Ka whakaritea ki nga umanga noa, he maama te tango i nga pooti. I tua atu, i kitea e te rangahau me te piki ake o te koki tarai, he nui ake te rohe radiation. Ina ko te koki tarai he 20 nga nekehanga, ko te rohe o te waahi ka horoia he 10 nga waa o te noa ake o te patunga, he pai ake te whakapai ake i te mahi horoi laser.
4. Ma te nui o te tuuturu e pai ake ai te horoi horoi laser
Ka rere ke te momo horoi mo nga tini tuuturu. Ko te horoi ko te tikanga mo te pahūtanga o te papanga mata i te waatea, ka nui te rahi o te kohinga, ka hurihia te peita peita mai i te wahanga ki te ruaki.
Hei arotau i te paanga o te horoi laser ki runga i nga papa whakarewa, he mea tika kia whakaarohia paitia te tikanga horoi o te laser, te horoi horoi tauira, te momo laser, te roanga laser, te kaha o te kaha, te kaha, te auau parani, te waa ka wero, me te ahunga a laser ahuru. Ka taea e te laser pulsed te horoi pai i te koraha o te maitai o te waro. I te wa he 1064nm te puhanga, 500W te mana o te laser, 10kHz te rekoata, he 10kHz te whanui, he 120n te tere, he 60mm / s, ko te reiti takahuri he 5%. Ko te mea korikori te mea pai ake, me te aroaro o te hāora he kore i kitea i te horoi o te kiri o te puehu, nga waahi-micro, nga raina me nga tohu. Ko te maatauranga raupaparorohiko anake e taea te hanga i tetahi punaha horoi laser tino pai.
