Kev kis tus kabmob Coronavirus tau ua rau tib neeg muaj kev ntxhov siab los ntawm ib puag ncig los ntawm cov kab mob, thiab tseem cuam tshuam rau lub neej niaj hnub ntawm tib neeg thiab kev ua haujlwm ntawm tib neeg.Nyob rau hauv lub ntsej muag ntawm ib puag ncig muaj kuab paug ntau zuj zus, sib sib zog nqus ultraviolet lub teeb-emitting diode tshuaj tua kab mob technology tau los ua, uas tau ua tau zoo nyob rau hauv lub tshav pob ntawm cov tshuaj tua kab mob thiab muaj dav kev lag luam prospects.Thaum muaj kev sib kis, UVC LED cov khoom siv ultraviolet tau dhau los ua cov khoom muag zoo tshaj plaws rau kev tua kab mob thiab ua kom tsis muaj menyuam 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.
Nrog rau kev tawg ntawm UVC LED kev lag luam, kev lag luam luam ntawv kuj tau siv lub sijhawm rau kev hloov pauv thiab hloov kho dua tshiab, thiab txawm tias tag nrho UV teeb kev lag luam tau coj los ua lub sijhawm rau kev hloov pauv thiab hloov kho dua tshiab.Xyoo 2008, thawj qhov tshwm sim ntawm LED UV teeb kho tshuab ntawm German Drupa Printing Technology thiab Equipment Exhibition tau zoo kawg nkaus thiab nyiam cov xim zoo nkauj, nyiam cov xim zoo nkauj los ntawm cov tuam txhab luam ntawv thiab cov chaw muab kev pabcuam luam ntawv.Cov kws tshaj lij hauv kev lag luam luam ntawv tau muab kev qhuas rau 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 curing technology
UV LED curing tshuab yog ib txoj kev luam ntawv uas siv UV-LED lub teeb-emitting diodes li curing qhov chaw.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 cov tsoos UV teeb qhov chaw (lub teeb mercury), lub spectral ib nrab-dav ntawm UV LED yog qhov nqaim ntau dua, thiab lub zog yuav muaj zog heev, tsis tshua muaj hluav taws xob, kev siv hluav taws xob siab, thiab ntau dua irradiation.Kev siv UV-LED lub teeb ci tuaj yeem txo qhov pov tseg ntawm cov khoom siv luam ntawv thiab txo cov nqi luam ntawv, yog li txuag lub sijhawm ntawm cov lag luam luam ntawv thiab txhim kho kev lag luam ntau lawm.
Nws yog ib qho tsim nyog hais tias UV LED curing tshuab siv ultraviolet band nyob rau hauv thaj tsam ntawm 365nm mus rau 405nm, uas belongs rau lub wavelength ultraviolet ntev (tseem hu ua UVA band), tsis muaj thermal tawg puas, uas tuaj yeem ua rau saum npoo ntawm UV. number case qhuav sai sai thiab txhim kho gloss ntawm cov khoom.Lub wavelength ntau yam siv nyob rau hauv lub tshav pob ntawm cov tshuaj tua kab mob ultraviolet yog nyob nruab nrab ntawm 190nm thiab 280nm, uas belongs rau ultraviolet luv bar (tseem hu ua UVC band).Qhov band ntawm UV ultraviolet lub teeb no tuaj yeem cuam tshuam ncaj qha rau DNA thiab RNA qauv ntawm cov hlwb thiab cov kab mob, thiab ua rau cov kab mob tuag sai.
Daim ntawv thov ntawm UV LED curing technology los ntawm txawv teb chaws manufacturers
Aztec Label, tus thawj coj hauv MicroLED thev naus laus zis, tshaj tawm tias nws tau ua tiav thiab txhim kho nws qhov loj tshaj plaws LED UV ziab tshuab, uas yuav hloov tag nrho lub Hoobkas tsim khoom rau hom tshuab no thaum kawg ntawm lub xyoo.Tom qab kev txhim kho ua tiav ntawm thawj LED UV kho qhov system ntawm ob-xim xovxwm xyoo tas los, lub tuam txhab tab tom txhim kho Benford LED UV kho qhov system thib ob ntawm nws lub tsev hauv paus hauv West Midlands kom txo qis kev siv hluav taws xob ntxiv.
Feem ntau, kev siv LED UV tshuab luam ntawv tuaj yeem ua rau tus number case qhuav hauv ib qho sai.LED UV teeb ntawm Aztec Label system tuaj yeem hloov mus rau thiab tawm tam sim, tsis tas yuav tsum muaj lub sijhawm txias, thiab nws yog ua los ntawm LED UV diode, yog li lub neej kev pab cuam ntawm nws cov cuab yeej tuaj yeem ncav cuag 10,000-15,000 teev.
Tam sim no, kev txuag hluav taws xob thiab "dual carbon" tau dhau los ua ib qho ntawm cov lus qhia tseem ceeb rau kev txhim kho cov kev lag luam loj.Colin Le Gresley, tus thawj tswj hwm ntawm Aztec Label, kuj tseem hais txog lub tuam txhab tsom mus rau qhov qauv no, piav qhia tias "kev ruaj khov yog tiag tiag los ua qhov sib txawv tseem ceeb rau kev lag luam thiab qhov tseem ceeb xav tau rau cov neeg siv khoom kawg".
Colin Le Gresley kuj tau taw qhia tias nyob rau hauv cov nqe lus ntawm kev ua tau zoo, Benford Environmental LED UV cov khoom tshiab tuaj yeem nqa cov txiaj ntsig luam tawm tau zoo thiab cov xim zoo nkauj, ua rau kev luam ntawv zoo thiab tsis muaj cov cim."Los ntawm qhov pom kev ruaj ntseg, nws siv zog tsawg dua, ntau dua 60 feem pua tsawg dua li cov pa UV kom qhuav.Ua ke nrog kev hloov pauv tam sim, lub neej ntev diodes thiab cov pa hluav taws xob qis, nws muab cov neeg siv khoom ua tau zoo siab rau qib, thaum ua kom zoo nrog peb cov hom phiaj kev ruaj ntseg. "
Txij li thaum txhim kho thawj Benford system, Aztec Label tau txaus siab rau nws cov qauv yooj yim, nyab xeeb thiab ua tau zoo.Tam sim no, lub tuam txhab tau txiav txim siab los nruab qhov thib ob, qhov loj dua.
Cov ntsiab lus
Ua ntej, nrog kev pom zoo thiab kev siv ntawm "Minamata Convention" nyob rau hauv 2016, kev tsim thiab ntshuam thiab xa tawm cov khoom uas muaj mercury yuav raug txwv los ntawm 2020 (feem ntau ntawm cov tsoos UV teeb pom kev zoo siv mercury teeb).Tsis tas li ntawd, thaum lub Cuaj Hlis 22, 2020, Tuam Tshoj tau ua piv txwv nyob rau hauv 75th kev sib ntsib ntawm United Nations General Assembly tau hais lus rau "cov pa roj carbon ncov thiab cov pa roj carbon nruab nrab" cov tuam txhab Suav yuav tsom kom txo qis kev siv hluav taws xob thiab txhim kho kev ua haujlwm, thiab paub txog cov digital. thiab ntse hloov kho ntawm cov lag luam.Nrog rau kev ua haujlwm tsis tu ncua ntawm kev luam ntawv thev naus laus zis thiab kev txhim kho ntawm kev tiv thaiv ib puag ncig hauv kev lag luam luam ntawv yav tom ntej, UV-LED luam ntawv thev naus laus zis yuav ua kom paub tab, uas yuav pab tau kev lag luam luam ntawv hloov pauv thiab txhim kho thiab txhim kho kom muaj zog.
