Qhov kev sib kis ntawm tus kab mob Coronavirus tau ua rau tib neeg ntxhov siab vim muaj cov kab mob nyob ib puag ncig, thiab kuj tau cuam tshuam loj heev rau lub neej txhua hnub ntawm cov tib neeg thiab kev ua haujlwm ib txwm ntawm lub zej zog. Thaum muaj kev ua qias tuaj ib puag ncig hnyav zuj zus, kev siv tshuab tua kab mob ultraviolet lub teeb ci ntsa iab tau tshwm sim, uas tau ua tiav zoo hauv kev tua kab mob thiab muaj kev cia siab dav hauv kev lag luam. Thaum muaj kev sib kis, cov khoom siv UVC LED ultraviolet tau dhau los ua cov khoom muag zoo tshaj plaws rau kev tua kab mob thiab kev tua kab mob vim lawv qhov zoo ntawm qhov me me, kev siv hluav taws xob tsawg, kev phooj ywg ib puag ncig, thiab teeb pom kev zoo tam sim ntawd.
Nrog rau kev tawg ntawm UVC LED kev lag luam, kev lag luam luam ntawv kuj tau qhib lub sijhawm rau kev hloov pauv thiab kev txhim kho, thiab txawm tias tag nrho kev lag luam teeb UV tau qhib lub sijhawm rau kev hloov pauv thiab kev txhim kho. Xyoo 2008, thawj zaug tshwm sim ntawm LED UV teeb kho tshuab ntawm German Drupa Printing Technology thiab Equipment Exhibition tau zoo heev thiab nyiam ntau qhov kev saib xyuas, nyiam kev saib xyuas zoo los ntawm cov chaw tsim khoom siv luam ntawv thiab cov neeg muab kev pabcuam luam ntawv. Cov kws tshaj lij hauv kev lag luam luam ntawv tau qhuas cov thev naus laus zis no, thiab ntseeg tias LED UV teeb kho tshuab yuav dhau los ua cov thev naus laus zis tseem ceeb ntawm kev kho hauv kev lag luam luam ntawv yav tom ntej.
UV LED teeb kho tshuab
UV LED curing technology yog ib txoj kev luam ntawv uas siv UV-LED lub teeb-emitting diodes ua lub teeb kho. Nws muaj qhov zoo ntawm lub neej ntev, lub zog siab, kev siv hluav taws xob tsawg, thiab tsis muaj kuab paug (mercury). Piv nrog rau lub teeb UV ib txwm muaj (mercury teeb), lub spectral ib nrab ntawm UV LED nqaim dua, thiab lub zog yuav muaj zog heev, tsim cua sov tsawg, siv hluav taws xob zoo, thiab muaj kev cuam tshuam zoo dua. Kev siv lub teeb UV-LED tuaj yeem txo qhov pov tseg ntawm cov peev txheej luam ntawv thiab txo cov nqi luam ntawv, yog li txuag lub sijhawm tsim khoom ntawm cov lag luam luam ntawv thiab txhim kho kev ua haujlwm ntawm cov lag luam.
Nws tsim nyog hais tias UV LED curing technology siv cov ultraviolet band hauv qhov ntau ntawm 365nm txog 405nm, uas yog ib feem ntawm cov ultraviolet ntev (tseem hu ua UVA band), tsis muaj kev puas tsuaj los ntawm thermal radiation, uas tuaj yeem ua rau qhov chaw ntawm UV number case qhuav sai thiab txhim kho qhov ci ntawm cov khoom. Qhov wavelength ntau yam siv hauv kev tua kab mob ultraviolet yog ntawm 190nm thiab 280nm, uas yog ib feem ntawm cov ultraviolet luv luv (tseem hu ua UVC band). Cov kab no ntawm UV ultraviolet lub teeb tuaj yeem rhuav tshem cov qauv DNA thiab RNA ntawm cov hlwb thiab cov kab mob, thiab ua rau cov kab mob tuag sai.
Kev siv tshuab UV LED curing los ntawm cov tuam txhab tsim khoom txawv teb chaws
Aztec Label, ib lub tuam txhab ua lag luam hauv MicroLED technology, tshaj tawm tias nws tau ua tiav thiab teeb tsa nws lub tshuab ziab LED UV loj tshaj plaws, uas yuav hloov nws lub Hoobkas tag nrho mus rau hom tshuab no thaum kawg ntawm lub xyoo. Tom qab kev teeb tsa thawj lub tshuab kho LED UV ntawm lub tshuab luam ntawv ob xim xyoo tas los, lub tuam txhab tab tom teeb tsa lub tshuab kho Benford LED UV thib ob ntawm nws lub hauv paus West Midlands kom txo qis kev siv hluav taws xob.
Feem ntau, kev siv cov thev naus laus zis LED UV luam ntawv tuaj yeem ua rau cov kua qhuav sai sai. Lub teeb LED UV ntawm Aztec Label system tuaj yeem qhib thiab kaw tam sim ntawd, tsis tas yuav siv sijhawm txias, thiab nws yog ua los ntawm LED UV diode, yog li lub neej kev pabcuam ntawm nws cov khoom siv tuaj yeem ncav cuag 10,000-15,000 teev.
Tam sim no, kev txuag hluav taws xob thiab "ob chav carbon" tab tom dhau los ua ib qho ntawm cov lus qhia tseem ceeb rau kev txhim kho cov lag luam loj. Colin Le Gresley, tus thawj coj dav dav ntawm Aztec Label, kuj tau hais txog lub tuam txhab txoj kev tsom mus rau qhov sib txawv no, piav qhia tias "kev ruaj khov yeej yog qhov tseem ceeb rau cov lag luam thiab qhov xav tau tseem ceeb rau cov neeg siv khoom kawg".
Colin Le Gresley kuj tau taw qhia tias hais txog qhov zoo, cov khoom siv Benford Environmental LED UV tshiab tuaj yeem coj cov txiaj ntsig luam ntawv pheej yig thiab cov xim ci ntsa iab, ua rau qhov zoo ntawm kev luam ntawv ruaj khov thiab tsis muaj cim. "Los ntawm qhov pom ntawm kev ruaj khov, nws siv hluav taws xob tsawg dua, ntau dua 60 feem pua tsawg dua li kev ziab UV ib txwm muaj. Ua ke nrog kev hloov pauv tam sim ntawd, cov diodes ntev thiab cov pa roj carbon dioxide tsawg, nws xa cov kev ua tau zoo siab uas cov neeg siv khoom xav tau, thaum ua tiav zoo nrog peb lub hom phiaj kev ruaj khov."
Txij li thaum txhim kho thawj lub tshuab Benford, Aztec Label tau zoo siab rau nws txoj kev tsim qauv yooj yim, muaj kev nyab xeeb thiab kev ua tau zoo. Tam sim no, lub tuam txhab tau txiav txim siab los txhim kho lub tshuab thib ob, loj dua.
Kev Txheeb Xyuas
Ua ntej, nrog kev pom zoo thiab kev siv ntawm "Minamata Convention" hauv xyoo 2016, kev tsim khoom thiab kev xa tawm ntawm cov khoom muaj mercury yuav raug txwv txij li xyoo 2020 (feem ntau ntawm cov teeb pom kev zoo UV ib txwm siv cov teeb mercury). Tsis tas li ntawd, thaum lub Cuaj Hlis 22, 2020, Tuam Tshoj tau teeb tsa ib qho piv txwv hauv kev sib tham 75th ntawm United Nations General Assembly tau hais lus txog "carbon peak thiab carbon neutrality" Cov tuam txhab Suav yuav tsom mus rau kev txo kev siv hluav taws xob thiab txhim kho kev ua haujlwm zoo, thiab paub txog kev hloov pauv digital thiab ntse ntawm cov tuam txhab. Nrog rau kev tshawb pom tas mus li ntawm cov thev naus laus zis luam ntawv thiab kev txhim kho kev tiv thaiv ib puag ncig hauv kev lag luam luam ntawv yav tom ntej, UV-LED luam ntawv thev naus laus zis yuav txuas ntxiv mus, uas yuav pab kev lag luam luam ntawv hloov pauv thiab txhim kho thiab txhim kho kom muaj zog.
