Laser tu tshuab yog ib txoj kev tu zoo thiab ib puag ncig zoo. Nws siv cov kab teeb ci laser los cuam tshuam nrog cov xim graffiti, ua rau cov xim kom sov sai thiab vaporize, yog li ua tiav cov txiaj ntsig ntawm kev tshem graffiti los ntawm graffiti nto. Txoj kev no tsis ua rau muaj kev puas tsuaj rau qhov chaw hauv qab thiab tsis tas yuav siv cov kuab tshuaj lom neeg, ua rau nws zoo rau ib puag ncig.
Raws li kev tshawb fawb tau, daim ntawv thov ntawm laser tu tshuab hauv kev tshem tawm txoj kev graffiti tau dav lees paub thiab kawm. Piv txwv li, kev sim cov ntaub ntawv ntawm graffiti tshem tawm los ntawm TEA CO2 laser nyob rau hauv ntau yam qhia tau hais tias thaum lub laser zog ceev yog 4 ~ 6 J / cm², qhov kev tshem tawm efficiency yog siab tshaj, thiab lub graffiti cheeb tsam tshem tawm ib chav tsev zog tshaj 2.5 cm² / J. . Qhov no qhia tau hais tias laser tu tshuab muaj qhov cuam tshuam tseem ceeb hauv kev tshem graffiti.
Tsis tas li ntawd, qhov zoo ntawm cov tshuab ntxuav laser yog lawv cov kev ua haujlwm siab, lub sijhawm thiab tus nqi txuag, kev tiv thaiv ib puag ncig, kev tiv thaiv nto thiab ntau yam. Lawv tuaj yeem siv rau ntawm ntau qhov chaw, suav nrog pob zeb, cib, hlau, thiab txawm tias cov ntaub ntawv muag zoo li iav lossis marble, tsis muaj kev puas tsuaj rau hauv qab.
Hauv kev ua haujlwm tiag tiag, lub tshuab ntxhua khaub ncaws laser raug txheeb xyuas thaj chaw graffiti los ntawm kev siv tshuab scanning thiab aiming technology, thiab tom qab ntawd cov emission laser beam absorbed los ntawm cov pigments los yog cov khoom nyob rau hauv graffiti, ua rau lawv sai sai kub thiab vaporize, thiab thaum kawg cov pa roj. zoo tshem tawm los ntawm lub tshuab nqus tsev los yog lwm yam txhais tau tias, tawm hauv qhov chaw huv si thiab tsis muaj graffiti.
Laser tu tshuab tsis yog tsuas yog tsim nyog rau kev tshem tawm txoj kev graffiti, tab sis kuj tseem siv tau rau ntau yam xws li kev tiv thaiv kab lis kev cai thiab kev lag luam tu. Piv txwv li, nws tuaj yeem siv los tshem tawm cov kab xeb, cov xim pleev xim thiab cov roj stains ntawm cov hlau, nrog rau cov khoom siv hluav taws xob huv, kev coj noj coj ua, thiab lwm yam.
Zuag qhia tag nrho, laser tu tshuab muab kev ua tau zoo, ib puag ncig tus phooj ywg thiab qhov chaw-phooj ywg rau kev tshem tawm hauv nroog graffiti, pab kho thiab tiv thaiv kev zoo nkauj thiab kev huv ntawm cov chaw hauv nroog.
