Kufalikira kwa kachilombo ka Coronavirus kwaika anthu mu nkhawa yoti azizunguliridwa ndi mabakiteriya, komanso kwakhudza kwambiri moyo watsiku ndi tsiku wa anthu komanso magwiridwe antchito abwinobwino a anthu. Poyang'anizana ndi kuipitsidwa kwakukulu kwa chilengedwe, ukadaulo wothira ma diode disinfection wa deep ultraviolet light-emitting dioxide unayamba kugwiritsidwa ntchito, womwe wapanga zinthu zabwino kwambiri pankhani yothira ma disinfection ndipo uli ndi mwayi waukulu pamsika. Panthawi ya mliriwu, zinthu za UVC LED ultraviolet zakhala zinthu zogulitsidwa kwambiri zothira ma disinfection ndi sterilization chifukwa cha ubwino wake wochepa, kugwiritsa ntchito mphamvu zochepa, kusamala chilengedwe, komanso kuunikira nthawi yomweyo.
Ndi kufalikira kwa makampani opanga ma LED a UVC, makampani osindikiza abweretsanso mwayi wosintha ndi kukweza, ndipo ngakhale makampani onse opanga ma UV abweretsa mwayi wosintha ndi kukweza. Mu 2008, kuwonekera koyamba kwa ukadaulo wopangira ma LED UV pa chiwonetsero chaukadaulo ndi zida ku Germany Drupa Printing Technology and Equipment kunali kodabwitsa ndipo kunakopa chidwi cha anthu ambiri, kukopa chidwi chachikulu kuchokera kwa opanga zida zosindikizira ndi opereka chithandizo chosindikizira. Akatswiri pamsika wosindikiza ayamikira kwambiri ukadaulo uwu, ndipo akukhulupirira kuti ukadaulo wopangira ma LED UV udzakhala ukadaulo waukulu wopangira ma LED mumakampani osindikiza mtsogolo.
Ukadaulo wochiritsa kuwala kwa UV LED
Ukadaulo wopopera wa UV LED ndi njira yosindikizira yomwe imagwiritsa ntchito ma diode otulutsa kuwala a UV-LED ngati magwero opopera kuwala. Ili ndi ubwino wokhala ndi moyo wautali, mphamvu zambiri, kugwiritsa ntchito mphamvu zochepa, komanso kusakhala ndi kuipitsidwa (mercury). Poyerekeza ndi gwero lakale la kuwala kwa UV (nyali ya mercury), theka la m'lifupi la UV LED ndi locheperako, ndipo mphamvuyo idzakhala yochuluka kwambiri, kupanga kutentha kochepa, kugwiritsa ntchito mphamvu zambiri, komanso kuwala kofanana. Kugwiritsa ntchito gwero la kuwala la UV-LED kungachepetse kuwononga zinthu zosindikizira ndikuchepetsa ndalama zosindikizira, motero kusunga nthawi yopangira makampani osindikiza ndikukweza kwambiri magwiridwe antchito opanga.
Ndikoyenera kunena kuti ukadaulo wochiritsa wa UV LED umagwiritsa ntchito gulu la ultraviolet lomwe lili pakati pa 365nm ndi 405nm, lomwe ndi la ultraviolet ya mafunde aatali (lomwe limadziwikanso kuti gulu la UVA), popanda kuwonongeka kwa kutentha, komwe kungapangitse pamwamba pa inki ya UV kuuma mwachangu ndikuwonjezera kuwala kwa chinthucho. Kutalika kwa kutalika kwa nthawi komwe kumagwiritsidwa ntchito pochiza matenda a ultraviolet kuli pakati pa 190nm ndi 280nm, komwe ndi la ultraviolet short bar (lomwe limadziwikanso kuti gulu la UVC). Gululi la kuwala kwa UV ultraviolet limatha kuwononga mwachindunji kapangidwe ka DNA ndi RNA ka maselo ndi ma virus, ndikuyambitsa kufa mwachangu kwa tizilombo toyambitsa matenda.
Kugwiritsa ntchito ukadaulo wochiritsa wa UV LED ndi opanga akunja
Aztec Label, yomwe ndi mtsogoleri mu ukadaulo wa MicroLED, yalengeza kuti yapanga ndikuyika bwino makina ake akuluakulu owumitsa a LED UV, omwe asintha kupanga kwake konse kwa fakitale kukhala ukadaulo wamtunduwu kumapeto kwa chaka. Pambuyo pokhazikitsa bwino makina oyamba oyeretsera a LED UV pamakina osindikizira amitundu iwiri chaka chatha, kampaniyo ikuyika makina ena oyeretsera a Benford LED UV ku likulu lawo la West Midlands kuti achepetse kugwiritsa ntchito mphamvu.
Kawirikawiri, kugwiritsa ntchito ukadaulo wa kusindikiza kwa LED UV kungapangitse inki kuuma nthawi yomweyo. Kuwala kwa LED UV kwa dongosolo la Aztec Label kumatha kuyatsidwa ndikuzimitsidwa nthawi yomweyo, palibe nthawi yoziziritsira yomwe imafunika, ndipo imapangidwa ndi LED UV diode, kotero nthawi yogwira ntchito yomwe ikuyembekezeka ya zida zake imatha kufika maola 10,000-15,000.
Pakadali pano, kusunga mphamvu ndi "dual carbon" zikukhala chimodzi mwa njira zofunika kwambiri pakukweza mafakitale akuluakulu. Colin Le Gresley, manejala wamkulu wa Aztec Label, adawonetsanso momwe kampaniyo ikuyang'ana kwambiri izi, pofotokoza kuti "kukhazikika kwa zinthu kukukhaladi chinthu chofunikira kwambiri pakusiyanitsa mabizinesi ndi kufunikira kwakukulu kwa makasitomala omaliza".
Colin Le Gresley ananenanso kuti pankhani ya ubwino, zida zatsopano za Benford Environmental LED UV zitha kubweretsa zotsatira zotsika mtengo zosindikizira komanso mitundu yowala, zomwe zimapangitsa kuti kusindikiza kukhale kokhazikika komanso kopanda zizindikiro. "Kutengera ndi momwe zinthu zilili, zimadya mphamvu zochepa kwambiri, zochepera 60 peresenti poyerekeza ndi kuuma kwa UV wamba. Kuphatikiza ndi kusintha kwachangu, ma diode okhalitsa komanso kutulutsa kutentha kochepa, zimapangitsa kuti makasitomala azigwira bwino ntchito, pomwe zikugwirizana bwino ndi zolinga zathu zosamalira chilengedwe."
Kuyambira pomwe adakhazikitsa makina oyamba a Benford, Aztec Label yachita chidwi ndi kapangidwe kake kosavuta komanso kotetezeka komanso zotsatira zake zabwino. Pakadali pano, kampaniyo yaganiza zokhazikitsa makina ena akuluakulu.
Chidule
Choyamba, ndi kuvomerezedwa ndi kukhazikitsidwa kwa "Msonkhano wa Minamata" mu 2016, kupanga ndi kutumiza kunja ndi kutumiza zinthu zomwe zili ndi mercury kudzaletsedwa kuyambira 2020 (maunikidwe ambiri achikhalidwe a UV amagwiritsa ntchito nyali za mercury). Kuphatikiza apo, pa Seputembala 22, 2020, China idapereka chitsanzo mu gawo la 75 la Msonkhano Waukulu wa United Nations yomwe idapereka nkhani yokhudza "kuchepa kwa mpweya ndi kusalowerera ndale kwa mpweya" mabizinesi aku China adzafuna kuchepetsa kugwiritsa ntchito mphamvu ndikuwonjezera magwiridwe antchito, ndikukwaniritsa kusintha kwa digito ndi kwanzeru kwa mabizinesi. Ndi kupita patsogolo kosalekeza kwa ukadaulo wosindikiza komanso chitukuko cha kuteteza chilengedwe m'makampani osindikiza mtsogolomu, ukadaulo wosindikiza wa UV-LED upitiliza kukula, zomwe zithandiza makampani osindikiza kusintha ndikusintha ndikukula mwamphamvu.
