Jun 09, 2023
Soot deposits tsim teeb meem loj dua li feem ntau xav. Lub facades ntawm tsev nyob rau hauv ib puag ncig hauv nroog feem ntau yog cov neeg raug tsim txom ntawm nws, ib yam li cov pej thuam thiab lwm yam kev kos duab. Infrastructural lug xws li txuas hniav, tuaj yeem raug kev txom nyem los ntawm soot deposits.
Kev tshem tawm cov kua qaub feem ntau yog ua los ntawm kev siv cov khoom siv tshuaj. Cov txheej txheem no tsis yog ib txwm ua tau zoo thiab tseem muaj kev phom sij rau tib neeg thiab ib puag ncig. Qhov no kuj feem ntau yog cov txheej txheem phau ntawv uas yuav tsum tau txhuam ntau heev thiab yog li siv sijhawm ntau heev.
Laser tu yog ib qho cuab yeej zoo heev los tshem cov quav. Soot ua tau raws li qhov yuav tsum tau ua ntawm laser tu zoo kawg nkaus: nyias, txheej dub. Cov xim dub muaj cov cuab yeej uas nws tsis cuam tshuam ntau lub teeb tab sis absorbs yuav luag txhua yam. Qhov no tsuas yog qhov peb xav tau nrog kev tu lub laser: Soot absorbs lub teeb luv luv, lub zog pulses, ua rau cov pa taws mus rau qhov luv luv tab sis muaj zog heev. Qhov no yuav muaj zog heev uas qhov kub ntawm ablation mus txog thiab vim li ntawd, cov av yuav evaporate. Dab tsi tseem yog qhov chaw huv si zoo kawg nkaus nrog cov hmoov av me ntsis ntawm no thiab nyob ntawd uas koj tuaj yeem tshuab tau yooj yim.
Rau saum npoo, peb saib yuav luag txhua yam khoom siv uas muaj peev xwm tiv taus qhov kub thiab txias ntawm 100 degree thiab ntau dua. Cov cua kub tiag tiag tshwm sim hauv cov hmoov av nws tus kheej thiab tsis nyob hauv cov khoom siv hauv qab, tab sis cov cua sov los ntawm cov evaporated soot tseem radiates me ntsis rau ntawm qhov chaw, yog li ntawd peb muaj qee yam kev xav tau rau cov ntaub ntawv.
Qhov no coj peb mus rau qhov chaw hauv qab no uas tsim nyog rau kev tshem tawm ntawm soot, txawm tias cov xuab zeb tau nyob ntawd ntev ntev:
Cib
Pob zeb
iav
Hlau
Cam khwb cia hlau
Aluminium
Chrome txheej
Ntuj pob zeb
Vuas thiab ceramics
Feem ntau hom ntoo
Plaster
