Qhov txawv ntawm UV-A thiab UV-C yog dab tsi?

Qhov ntau yam ntawm lub teeb ultraviolet yuav luag sib npaug ntawm qhov pom spectrum ntau xim. Tab sis thaum peb xav txog cov hluav taws xob ultraviolet, peb nquag saib qhov no thiab hloov pauv nws raws li ib pawg ntawm cov wavelengths nrog rau kev siv hauv kev ntxuav, kho, thiab fluorescence nrog rau qhov muaj peev xwm ua rau mob qog noj ntshav. Txawm li cas los xij, vim tias txhua hom ultraviolet lub zog muaj qhov sib txawv ntawm qhov zoo, nws yog ib qho tseem ceeb kom paub qhov txawv ntawm lawv. Qhov sib txawv tseem ceeb ntawm UV-A thiab UV-C hluav taws xob nyob rau hauv cov nqe lus ntawm lawv cov kev siv thiab kev siv yog nyob rau hauv tsab xov xwm no.

Ua ntej, nrhiav tus nqi wavelength.

Ua ntej thiab qhov tseem ceeb, lub wavelength yuav tsum tau siv los txheeb xyuas lub zog ultraviolet. Hom hluav taws xob ultraviolet yog txiav txim los ntawm lub wavelength, uas qhia nyob rau hauv nanometers (nm). Thaum UV-C npog wavelengths ntawm 100 txog 280 nanometers, UV-A npog wavelengths ntawm 315 thiab 400 nanometers. Qhov ntau ntawm UV-B wavelengths yog 280 txog 315 nanometers.

Txij li UV-A thiab UV-C tsis tuaj yeem pom qhov txawv ntawm ib leeg hauv tib yam uas tib neeg tuaj yeem pom qhov pom tau tias lub teeb liab lossis xiav, qhov no tuaj yeem zoo li qhov tsis zoo. Yog li ntawd, nws yog qhov tseem ceeb tshaj plaws uas koj yuav tsum paub txog qhov wavelength ntawm lub teeb qhov chaw uas koj yuav xav tau rau koj daim ntawv thov tshwj xeeb thiab, qhov tsawg kawg nkaus, koj paub txog qhov sib txawv ntawm UV-A thiab UV-C hluav taws xob.

Fluorescence & Curing nyob rau hauv UV-A

Feem ntau ntawm UV-A teeb daim ntawv thov, uas siv lub wavelength ntawm 365 nanometers, tuaj yeem faib ua fluorescence lossis curing applications. Fluorescence yog ib qho tshwm sim uas cov tshuaj xws li cov xim, xim, lossis cov ntxhia hloov pauv lub zog ntawm UV-A rau ib lub teeb pom kev. Blacklights yog UV teeb uas tau siv rau lub hom phiaj no vim tias lawv pib tshwm tsaus nti tab sis tawm ntau yam xim pom thaum lawv ci rau ntau yam.

Ntawm no yog ib qho piv txwv ntawm lub pob zeb uas muaj fluoresces ntsuab thaum illuminated los ntawm realUVTM LED teeb nyem. Hauv ntau qhov chaw, suav nrog forensics, tshuaj, molecular biology, thiab geology, UV-A fluorescence yog qhov tseem ceeb heev vim tias nws yuav raug siv los txheeb xyuas cov ntsiab lus fluorescent uas yuav nyuaj rau kev ntxub ntxaug nyob rau hauv ib txwm teeb pom kev zoo.

Tsis yog tsuas yog siv kev tshawb fawb tuaj yeem ua tau nrog fluorescence. Fluorescence tuaj yeem ua haujlwm hauv fluorescence photography thiab blacklight art installations los muab ntau yam kev pom zoo rau kev pom. UV-A kuj tseem siv nyob rau hauv ntau qhov chaw lom zem, zoo li lub teeb ci ntsa iab uas koj yuav lossis tsis nco qab, los tsim cov teebmeem fluorescence.

365 nm thiab 395 nm yog qhov nrov tshaj plaws wavelengths rau UV-A fluorescence. Ob leeg 365 thiab 395 nm feem ntau yuav tsim cov teebmeem fluorescence, txawm li cas los xij 365 nm yuav ua li ntawd nrog "ntxhuv" UV nyhuv thiab pom lub teeb pom kev tsawg dua, thaum 395 nm yuav tsim me me ntawm pom violet lossis ntshav liab. Saib peb qhov kev sib piv ntawm 365 nm thiab 395 nm kom paub meej ntxiv.

Nyob rau hauv sib piv rau fluorescence, UV-A yog siv nyob rau hauv kev kho mob daim ntawv thov thiab tuaj yeem ua rau muaj kev hloov pauv tshuaj thiab cov qauv ntawm ntau yam ntaub ntawv. UV-A wavelengths siv rau kev kho yog tib yam, txawm tias kev kho feem ntau yuav tsum tau siv UV ntau dua. 365 nm yog ib qho kev siv wavelength uas nquag siv los kho, ib yam li fluorescence.

Epoxies rau kev lag luam siv, ntsia thawv gels, thiab emulsion xim hauv kev tshuaj ntsuam luam ntawv yog txhua yam kho tau nrog UV-A wavelengths. Hauv daim ntawv thov UV-A curing, tag nrho lub sijhawm raug yog qhov tseem ceeb ntxiv rau kev siv.

Daim ntawv thov ntawm UV-C rau Germicidal thiab Infection Control

UV-C wavelengths, piv rau UV-A wavelengths, muaj ntau qhov me me wavelength ntau (100 nm txog 280 nm). Ua kom pom tseeb tau muab tso rau ntawm UV-C wavelengths raws li txoj hauv kev ua kom tsis muaj kab mob xws li kab mob, kab mob, pwm, thiab fungi.

Vim qhov tseeb tias DNA thiab RNA yog qhov yooj yim rau kev puas tsuaj ntawm thiab nyob ib ncig ntawm 265 nanometers, UV-C yog lub zog muaj zog ntawm cov kab mob. Ob daim ntawv cog lus uas txuas thymine thiab adenine tau tawg thaum lub sijhawm txheej txheem hu ua dimerization thaum cov kab mob raug rau UV-C wavelength lub teeb, hloov genome tus qauv. Tus kab mob no tsis tuaj yeem ua tiav rov ua dua lossis ntau ntxiv los ntawm qhov kev hloov kho no, uas yog tshwm sim los ntawm kev ua tsis ncaj ntawm caj ces.

Vim tias thymine (los yog uracil hauv RNA) rhiab heev rau UV-C ntawm qhov tshwj xeeb wavelengths, UV-C yog qhov tshwj xeeb hauv nws lub peev xwm los ua cov tshuaj tua kab mob.

Tsis zoo li UV-C lub teeb, UV-A tsis muaj peev xwm pib dimerization. Txij li UV-A tsis tuaj yeem tsom rau DNA cov qauv ntawm cov kab mob, tag nrho cov pov thawj muaj qhia tias nws yog kev xaiv tsis zoo rau kev tua kab mob.

Mus saib peb nplooj ntawv mob siab rau UV-C LED thev naus laus zis kom paub meej ntxiv.

Nyob rau nruab hnub, UV-A yog tam sim no thaum UV-C tsis yog

Nws yog ib qho kev xav tsis zoo uas UV lub zog ntawm txhua yam muaj nyob rau hauv ntuj nruab hnub. Tag nrho UV lub zog wavelengths muaj nyob rau hauv lub hnub ci hluav taws xob, txawm li cas los xij tsuas yog UV-A thiab qee lub zog UV-B tuaj yeem nkag mus rau hauv lub ntiaj teb huab cua. Lub ozone txheej ntawm lub ntiaj teb, ntawm qhov tod tes, absorbs UV-C, tiv thaiv kom tsis txhob ncav cuag hauv av.

Txhua lub zog ultraviolet yuav tsum tau ua nrog ceev faj heev vim, raws li US HHS, tag nrho UV wavelengths, suav nrog UV-A, UV-B, thiab UV-C, xav tias yog carcinogenic. UV hluav taws xob yog qhov txaus ntshai tshwj xeeb vim tias peb tsis tau squint lossis tig peb lub taub hau los teb rau nws, zoo li peb ua nrog pom lub teeb. Txawm li cas los xij, txij li peb paub tias UV-A hluav taws xob tshwm sim feem ntau nyob rau nruab hnub nruab hnub, muaj ntau ntau cov kev tshawb fawb thiab cov kev tshawb fawb ntawm cov pej xeem uas pab peb nkag siab txog cov kev pheej hmoo thiab kev puas tsuaj uas UV-A hluav taws xob tuaj yeem tshwm sim.

Ntawm qhov tod tes, ib tus neeg ib txwm tsis raug UV-C hluav taws xob txhua hnub. Rau cov haujlwm tshwj xeeb thiab kev ua haujlwm, xws li vuam, feem ntau ntawm cov kev tshawb fawb tau ua nrog lub qhov muag rau kev ua haujlwm noj qab haus huv thiab kev nyab xeeb. Raws li qhov tshwm sim, kev tshawb fawb tsawg dua tau ua tiav ntawm kev phom sij thiab kev puas tsuaj los ntawm UV-C. Vim hais tias ntawm nws luv luv wavelength los ntawm ib tug physics foundations, UV-C muaj ib tug txiav txim siab lub zog ntau dua thiab paub hais tias ncaj qha mus ua phem DNA molecules. Nws yuav zoo rau xav tias nws muaj peev xwm ua rau neeg raug mob ntau dua li UV-A thiab UV-B, uas yog cov ntawv tsawg dua ntawm UV. Yog li ntawd, yuav tsum tau saib xyuas ntxiv kom tsis txhob raug UV-C.
