UV tubes (dub lub teeb raj)tuaj yeem teeb cov khoom fluorescent, muab cov nyhuv tshwj xeeb. Nkag siab cov yam ntxwv tseem ceeb thiab ua haujlwm nyab xeeb kom siv tau zoo.
Cov nyhuv excitation nyob ntawm ultraviolet lub teeb wavelength
UV tubes emit ultraviolet lub teeb ntawm 365nm (UVA) thiab 395nm (UVA / pom violet ntug). 365nm cov hlab emit tsawg pom violet lub teeb, muaj purer ultraviolet lub teeb, thiab muaj zog fluorescence excitation. Qhov chaw ib puag ncig yog tsaus dua thiab cov fluorescence muaj zog dua. 395nm cov raj xaim violet ntau dua, muaj qhov ua kom muaj zog qis dua, thiab ua kom muaj xim daj ntau dua . 365nm muaj fluorescence ntau dua, txawm li cas los xij 395nm yog pheej yig dua thiab xav paub ntau dua nrog ib puag ncig ntshav. Xyuas kom tseeb tias cov khoom dai, khaub ncaws, thiab coatings yog fluorescent.
UV tublub zog nyob ntawm qhov chaw npog
UV raj fais fab (watts) ncaj qha cuam tshuam rau ultraviolet hluav taws xob siv thiab ua kom pom kev zoo. Tsawg-lub zog (10-20W) ib leeg tuaj yeem teeb pom kev zoo nkauj ntawm lub desktop lossis cov ntawv me me tom qab. Teeb pom kev ua las voos loj dua hauv pem teb lossis phab ntsa yuav tsum muaj ntau lub siab - lub zog (40W lossis ntau dua) cov raj lossis cov teeb pom kev zoo UV array. Qhov chaw loj, qhov xav tau qhov ci, qhov siab ntawm lub raj, thiab lub kaum sab xis yuav tsum txiav txim siab tag nrho lub zog xav tau. Lub zog tsis txaus ua rau muaj kev cuam tshuam fluorescence tsis txaus.
Ua tib zoo saib xyuas kev nyab xeeb ntawm ultraviolet
UV rays, tshwj xeeb tshaj yog khaus UVA, yog qhov txaus ntshai. Tsis txhob ncua lub teeb ncaj qha mus rau lub teeb. Photokeratitis tej zaum yuav tshwm sim los ntawm luv- lub sij hawm siab - siv tau. Txhim kho cov kav dej ntau tshaj 2 meters saum kab ntawm qhov pom lossis siv cov khoom siv nrog cov hniav nyiaj hniav kub kom txo cov teeb pom kev ncaj qha. Cov tawv nqaij rhiab heev tuaj yeem redden tom qab raug UV ntev. Txwv ob tog rau 3-4 teev thiab cia cov qhua so hauv qhov tsis yog{12}}UV qhov chaw. Kev khiav hauj lwm cov teeb fluorescent UV qub tuaj yeem tawm me me ntawm ozone. LED UV tubes yog lub zog- ua haujlwm tau zoo, muaj zog, thiab tsis muaj ozone.
Kev teeb tsa thiab lub zog rau kev ruaj ntseg
UV teeb xav tau lub zog txhim khu kev qha. LED UV teeb siv ncaj qha tam sim no (12V / 24V) thiab xav tau lub adapter lossis hloov hluav taws xob. Traditional fluorescent UV teeb xav tau ballasts. Tsis txhob overloading fais fab mov kab los ntawm kev ua kom muaj zog txaus. Txhim kho cov teeb nrog cov hlua ruaj khov lossis cov khoom dai kom tsis txhob poob. Fluorescent qhov muag teev tsis tshua muaj kev poob siab- tiv taus ntau dua li LEDs.
Tsuas yog thaum txoj cai wavelength, lub zog, thiab kev teeb tsa thiab cov lus qhia siv tau ua raws li UV teeb lub raj muaj kev nyab xeeb thiab muaj txiaj ntsig zoo rau kev zoo nkauj rau tog. Ua ntej kev tiv thaiv kev noj qab haus huv ib txwm muaj.
