Cov ntsiab cai feem ntau lees txais yog ob npaug
"Kub ua" siv lub siab -zog- laser beam ceev (lub zog muaj zog txaus) los irradiate saum npoo ntawm cov khoom ua tiav. Cov khoom siv absorbs lub zog laser, tsim cov txheej txheem thermal excitation nyob rau hauv cheeb tsam irradiated, yog li nce qhov kub ntawm cov khoom nto (los yog txheej) thiab ua rau phenomena xws li alteration, melting, ablation, thiab evaporation.
"Cold processing" siv siab -zog (ultraviolet) photons muaj peev xwm ua txhaum cov tshuaj tiv thaiv hauv cov khoom (tshwj xeeb tshaj yog cov khoom siv organic) lossis cov nruab nrab nyob ib puag ncig, ua rau tsis yog - thermal puas. Qhov kev ua haujlwm txias no yog qhov tseem ceeb hauv laser npav vim tias nws tsis yog thermal ablation, tab sis yog qhov txias txias uas ua rau cov khoom siv tshuaj lom neeg tsis ua rau muaj kev cuam tshuam ntawm "thermal puas." Yog li ntawd, nws tsis kub los yog deform lub puab txheej los yog ib puag ncig ntawm cov txheej txheem nto. Piv txwv li, hauv kev lag luam hluav taws xob, excimer lasers yog siv los tso cov yeeb yaj kiab nyias ntawm cov tshuaj ntawm cov khoom siv substrate thiab tsim cov grooves nqaim ntawm semiconductor substrates.
Kev sib piv ntawm Cov Txheej Txheem Sib Txawv
Piv nrog rau inkjet npav, laser npav thiab engraving muaj qhov zoo ntawm: daim ntawv thov dav, muaj peev xwm ua tau ruaj khov siab {{0} cov ntaub ntawv zoo xws li hlau, iav, ceramics, plastics, thiab tawv. Nws tsis muaj zog ntawm lub workpiece nto, tsis ua rau txhua yam deformation, thiab tsis corrode rau saum npoo ntawm cov khoom.
Cov khoom siv
Nws tuaj yeem kos ntau yam tsis yog{0}}cov ntaub ntawv hlau. Cov ntawv thov suav nrog cov khoom siv hauv khaub ncaws, ntim tshuaj, ntim cawv, lub tsev ceramics, ntim dej haus, txiav ntaub, cov khoom siv roj hmab, cov npe ntawv, kos duab thiab khoom siv tes ua, cov khoom siv hluav taws xob, thiab kev lag luam tawv.
