Kuphulika kwa Coronavirus kwayika anthu nkhawa yokhala ndi mabakiteriya, komanso kwakhudza kwambiri moyo watsiku ndi tsiku wa anthu komanso momwe anthu amagwirira ntchito.Poyang'anizana ndi kuipitsidwa kwakukulu kwa chilengedwe, ukadaulo wakuya wa ultraviolet-emitting diode diode unakhalapo, womwe wachita bwino kwambiri pankhani yopha tizilombo ndipo uli ndi chiyembekezo chamsika wamsika.Panthawi ya mliri, zida za UVC za ultraviolet zakhala zogulitsidwa kwambiri zophera tizilombo toyambitsa matenda komanso kutseketsa chifukwa cha zabwino zake zazing'ono, kugwiritsa ntchito mphamvu zochepa, kusamala zachilengedwe, komanso kuyatsa nthawi yomweyo.
Ndi kuphulika kwa mafakitale a UVC LED, makampani osindikizira aperekanso mwayi wosintha ndi kukweza, ndipo ngakhale makampani onse a kuwala kwa UV abweretsa mwayi wosintha ndi kukweza.Mu 2008, mawonekedwe oyambirira a teknoloji yochiritsa ya kuwala kwa UV ku Germany Drupa Printing Technology ndi Equipment Exhibition inali yodabwitsa ndipo inakopa chidwi, kukopa chidwi chachikulu kuchokera kwa opanga zida zosindikizira ndi opereka chithandizo chosindikizira.Akatswiri mu msika yosindikizira apereka matamando mkulu kwa luso, ndipo amakhulupirira kuti LED UV kuwala kuchiritsa luso adzakhala luso lalikulu la kuchiritsa mu makampani osindikizira m'tsogolo.
Ukadaulo wochiritsa kuwala kwa UV LED
Ukadaulo wamachiritso a UV ndi njira yosindikizira yomwe imagwiritsa ntchito ma diode otulutsa kuwala kwa UV-LED ngati magwero ochiritsa.Lili ndi ubwino wokhala ndi moyo wautali, mphamvu zambiri, kugwiritsira ntchito mphamvu zochepa, komanso kulibe kuipitsidwa (mercury).Poyerekeza ndi gwero la kuwala kwa UV (nyali ya mercury), mawonekedwe owoneka bwino a UV LED ndi ocheperako, ndipo mphamvu zake zimakhala zokhazikika, kutulutsa kutentha pang'ono, kugwiritsa ntchito mphamvu zambiri, komanso kuyatsa kofananira.Kugwiritsa ntchito gwero la kuwala kwa UV-LED kumatha kuchepetsa kuwonongeka kwazinthu zosindikizira ndikuchepetsa ndalama zosindikizira, potero kupulumutsa nthawi yopanga mabizinesi osindikiza ndikuwongolera kwambiri magwiridwe antchito amakampani.
Ndikoyenera kunena kuti ukadaulo wochiritsa wa UV LED umagwiritsa ntchito gulu la ultraviolet la 365nm mpaka 405nm, lomwe ndi la ultraviolet lalitali (lomwe limadziwikanso kuti UVA band), popanda kuwonongeka kwa ma radiation, omwe amatha kupanga pamwamba pa UV. inki ziume msanga ndi kusintha gloss wa mankhwala.Kutalika kwa mafunde omwe amagwiritsidwa ntchito popha tizilombo toyambitsa matenda ku ultraviolet ndi pakati pa 190nm ndi 280nm, yomwe ndi ya ultraviolet short bar (yomwe imadziwikanso kuti UVC band).Gulu la kuwala kwa UV ultraviolet limatha kuwononga mwachindunji DNA ndi RNA kapangidwe ka maselo ndi ma virus, ndikupangitsa kufa mwachangu kwa tizilombo.
Kugwiritsa ntchito ukadaulo wochiritsa wa UV LED ndi opanga akunja
Aztec Label, mtsogoleri wa teknoloji ya MicroLED, adalengeza kuti yamanga bwino ndikuyika makina ake akuluakulu owumitsa a UV UV, omwe adzasintha kupanga fakitale yake yonse ku teknoloji yamtunduwu kumapeto kwa chaka.Kutsatira kukhazikitsidwa bwino kwa njira yoyamba yochiritsira ya LED UV pa makina osindikizira amitundu iwiri chaka chatha, kampaniyo ikukhazikitsa njira yachiwiri yochiritsa ya Benford LED UV ku likulu lawo ku West Midlands kuti achepetse kugwiritsa ntchito mphamvu.
Nthawi zambiri, kugwiritsa ntchito ukadaulo wosindikiza wa UV UV kumatha kupangitsa kuti inkiyo iume nthawi yomweyo.Kuwala kwa LED kwa UV kwa dongosolo la Aztec Label kumatha kuyatsidwa ndikuzimitsa nthawi yomweyo, palibe nthawi yozizira yomwe imafunika, ndipo imapangidwa ndi diode ya LED UV, kotero kuti moyo wautumiki wa zida zake ukhoza kufika maola 10,000-15,000.
Pakalipano, kupulumutsa mphamvu ndi "dual carbon" kukhala imodzi mwa njira zofunika kwambiri zopititsira patsogolo mafakitale akuluakulu.Colin Le Gresley, manejala wamkulu wa Aztec Label, adawunikiranso zomwe kampaniyo ikuyang'ana pa izi, pofotokoza kuti "kukhazikika kwakhala kusiyanitsa kwakukulu kwa mabizinesi komanso kufunikira kwamakasitomala".
Colin Le Gresley adanenanso kuti pankhani ya khalidwe, zida zatsopano za Benford Environmental LED UV zimatha kubweretsa zotsatira zosindikizira zotsika mtengo komanso mitundu yowoneka bwino, zomwe zimapangitsa kuti makina osindikizira azikhala okhazikika komanso opanda zizindikiro."Kutengera kukhazikika, imagwiritsa ntchito mphamvu zochepa kwambiri, zochepera 60 peresenti poyerekeza ndi kuyanika kwa UV wamba.Kuphatikizidwa ndi kusintha pompopompo, ma diode okhala ndi moyo wautali komanso mpweya wotentha pang'ono, kumapereka makasitomala omwe amayembekeza kwambiri, kwinaku akugwirizana bwino ndi zolinga zathu zokhazikika. ”
Chiyambireni kukhazikitsa dongosolo loyamba la Benford, Aztec Label yachita chidwi ndi njira zake zosavuta, zotetezeka komanso zotsatira zake.Pakadali pano, kampaniyo yasankha kukhazikitsa yachiwiri, yokulirapo.
Chidule
Choyamba, ndi chivomerezo ndi kukhazikitsidwa kwa "Minamata Convention" mu 2016, kupanga ndi kuitanitsa ndi kutumiza kunja kwa zinthu zomwe zili ndi mercury zidzaletsedwa kuyambira 2020 (zambiri zowunikira UV zimagwiritsa ntchito nyali za mercury).Kuphatikiza apo, pa Seputembara 22, 2020, China idapereka chitsanzo mu gawo la 75 la United Nations General Assembly idakamba nkhani yokhudza "carbon peak ndi kusalowerera ndale kwa kaboni" mabizinesi aku China akufuna kuchepetsa kugwiritsa ntchito mphamvu ndikuwongolera magwiridwe antchito, ndikuzindikira digito. ndi wanzeru kusintha mabizinesi.Ndi kupita patsogolo kosalekeza kwaukadaulo wosindikiza komanso kupititsa patsogolo chitetezo cha chilengedwe m'makampani osindikizira m'tsogolomu, ukadaulo wosindikizira wa UV-LED upitilira kukula, zomwe zithandizire makampani osindikiza kuti asinthe ndikukweza ndikukula mwamphamvu.
