Kev kho hniav lub teeb kho tshuab yog ib feem tseem ceeb ntawm kev kho hniav niaj hnub, siv cov wavelengths ntawm lub teeb los kho cov ntaub ntawv kho hniav. Txawm hais tias lasers tsis siv rau hauv cov txheej txheem kho lub teeb,kev tiv thaiv kev nyab xeebtseem tseem ceeb heev. Cov xov xwm no yuav qhia txog cov ntsiab cai ua haujlwm ntawm kev kho hniav kho hniav, piav qhia vim li caslaser tiv thaiv eyewear yog tsim nyog txawm nyob rau hauv tsis-laser ua hauj lwm, thiab muab tswv yim rau xaivlaser tiv thaiv eyewear.
1. Taw qhia
Kev kho hniav lub teeb kho siv cov khoom siv photosensitive uas hardens nyob rau hauv raug rau lub teeb ntawm ib lub wavelength tshwj xeeb. Cov txheej txheem no feem ntau yog siv rau hauv cov txheej txheem xws li kho hniav, kev sib txuas, thiab ua kom dawb. Vim muaj kev siv ntau ntawm lub teeb tawm los ntawm cov cuab yeej kho, muaj qee yam yuav tsum tau ua rau kev nyab xeeb ntawm lub qhov muag ntawm ob tus neeg ua haujlwm thiab cov neeg mob.
2. Cov Cai Ua Haujlwm ntawm Kev Kho Hniav Kho Hniav
Cov khoom siv kho hniav kho hniav siv hauv lub teeb kho lub teeb muaj cov photosensitizer uas ua kom qhib tau thaum raug lub teeb ntawm ib lub wavelength tshwj xeeb, ua rau muaj kev cuam tshuam tshuaj lom neeg. Cov tshuaj tiv thaiv no hloov pauv cov khoom siv los ntawm cov kua mus rau lub xeev khov kho los ntawm cov txheej txheem hu ua photopolymerization. Feem ntau qhov chaw ntawm lub teeb muaj xws li halogen teeb, LED teeb, thiab plasma arc teeb, uas muaj spectral outputs phim rau cov yam ntxwv haum ntawm photosensitizer.
3. Yog vim li cas Laser Protection Eyewear yog xav tau
Txawm hais tias tsis muaj Lasers Txawm hais tias kho hniav lub teeb kho tsis cuam tshuam nrog lasers, qhov siv ntawm lub teeb pom kev txaus txaus ua rau muaj kev phom sij rau lub qhov muag. Cov txiaj ntsig spectral ntawm cov peev txheej no tuaj yeem suav nrog cov khoom siv ultraviolet lossis xiav lub teeb, uas tuaj yeem ua rau lub ntsej muag puas lossis lub qhov muag raug mob nrog lub sijhawm ntev. Yog li ntawd, hnav looj tsom iav tiv thaiv laser yog qhov tsim nyog txawm tias tsis yog laser ua haujlwm.
| Hom Lub Teeb Qhov Chaw | Spectral Range | Muaj peev xwm txaus ntshai | Kev tiv thaiv |
|---|---|---|---|
| Halogen Teeb | Dav spectrum, suav nrog UV thiab pom lub teeb | UV hluav taws xob, lub teeb xiav hluav taws xob | Hnav UV / xiav lub teeb thaiv cov tsom iav |
| LED Teeb | Nqaim spectrum, feem ntau yog lub teeb xiav | Lub teeb xiav hluav taws xob | Hnav xiav lub teeb thaiv cov tsom iav |
| Plasma Arc Teeb | Dav spectrum, suav nrog UV thiab pom lub teeb | UV hluav taws xob, lub teeb xiav hluav taws xob | Hnav UV / xiav lub teeb thaiv cov tsom iav |
Ntau hom teeb pom kev zoo muaj qhov sib txawv spectral outputs. Piv txwv li, halogen teeb thiab plasma arc teeb muaj ntau yam dav dav uas suav nrog ultraviolet thiab pom lub teeb, thaum lub teeb LED muaj qhov nqaim spectrum feem ntau emitting xiav lub teeb. Cov hluav taws xob ultraviolet tuaj yeem ua rau lub cornea thiab conjunctiva ntawm lub qhov muag puas, thiab kev siv ntev ntev ntawm lub teeb xiav tuaj yeem ua rau lub qhov muag puas. Yog li ntawd, nws yog ib qho tseem ceeb uas yuav tsum tau hnav cov looj tsom iav kom tsim nyog raws li hom thiab spectral tso tawm ntawm lub teeb ci.
4. XaivLaser Protection EyewearThaum xaiv cov looj tsom iav laser, xav txog cov hauv qab no:
① OD Tus Nqi: Qhia txog lub peev xwm ntawm cov iav los thaiv lub teeb ntawm ib lub wavelength tshwj xeeb. Rau cov chaw tsis-laser, xaiv cov looj tsom iav tiv thaiv nrog tus nqi OD ntawm 3 lossis siab dua yog qhov txaus.
② Tiv thaiv Wavelength: Xaiv cov looj tsom iav tiv thaiv raws li qhov tso zis spectral ntawm lub teeb ci kom ntseeg tau tias muaj kev tiv thaiv ntawm txhua qhov teeb meem spectra.
③ Kev nplij siab thiab haum: Ua kom lub ntsej muag haum rau tus neeg hnav kom xis nyob yam tsis ua rau tsis xis nyob lossis qaug zog.
④ Daim ntawv pov thawj thiab cov qauv: Xaiv cov khoom uas tau dhau cov ntawv pov thawj kev nyab xeeb kom ntseeg tau tias lawv muaj txiaj ntsig zoo thiab kev tiv thaiv zoo.
5. Cov lus xaus
Kev kho hniav lub teeb kho tshuab yog ib qho tseem ceeb ntawm kev kho hniav niaj hnub. Txawm hais tias nws tsis koom nrog lasers, lub teeb pom kev zoo ntawm cov khoom siv ua rau kev tiv thaiv qhov muag pom qhov tseem ceeb sib npaug. Nkag siab txog cov qauv kev ua haujlwm thiab cov txiaj ntsig spectral ntawm cov teeb pom kev sib txawv, xaiv cov looj tsom iav uas tsim nyog, thiab siv cov kev tiv thaiv kom zoo tuaj yeem tiv thaiv ob lub qhov muag ntawm cov neeg ua haujlwm thiab cov neeg mob los ntawm ultraviolet thiab xiav lub teeb puas. Nrog rau kev tiv thaiv kom txaus thiab kev paub txog kev nyab xeeb, cov txheej txheem kho hniav yuav tsum muaj kev nyab xeeb thiab ua haujlwm tau zoo dua yav tom ntej. Raws li kev siv thev naus laus zis thiab kev nyab xeeb kev nco qab txhim kho, yav tom ntej ntawm cov txheej txheem kho hniav yuav tsum muaj kev nyab xeeb thiab ua haujlwm zoo dua.
