Ukuqubuka kweCoronavirus sekufake abantu osizini lokuzungezwa amagciwane, futhi sekuthinte kakhulu impilo yansuku zonke yabantu kanye nokusebenza okuvamile komphakathi.Lapho kubhekene nokungcoliswa kwemvelo okwandayo okwandayo, kwavela ubuchwepheshe obujulile bokubulala amagciwane e-ultraviolet light-emitting diode, obenze impumelelo enkulu emkhakheni wokubulala amagciwane futhi obunamathemba abanzi emakethe.Phakathi nalolu bhubhane, imikhiqizo ye-UVC LED ultraviolet isiphenduke imikhiqizo ethengiswa kakhulu yokubulala amagciwane kanye nokuvala inzalo ngenxa yezinzuzo zayo zobukhulu obuncane, ukusetshenziswa kwamandla okuphansi, ubungane bemvelo, kanye nokukhanyisa okusheshayo.
Ngokudlondlobala kwemboni ye-UVC LED, imboni yokunyathelisa iphinde yavula ithuba lokuguqulwa nokuthuthukiswa, futhi nayo yonke imboni yokukhanya kwe-UV ingenise ithuba lokuguqulwa nokuthuthukiswa.Ngo-2008, ukubonakala kokuqala kobuchwepheshe bokuphulukisa ukukhanya kwe-UV ye-LED e-German Drupa Printing Technology and Equipment Exhibition kwakumangalisa futhi kwadonsa ukunaka okukhulu, kudonsela ukunaka okukhulu kubakhiqizi bemishini yokunyathelisa nabahlinzeki benkonzo yokunyathelisa.Ochwepheshe emakethe yokunyathelisa banikeze udumo olukhulu kulobu buchwepheshe, futhi bakholelwa ukuthi ubuchwepheshe bokuphulukisa ukukhanya kwe-LED UV buzoba ubuchwepheshe obuyinhloko bokuphulukisa embonini yokunyathelisa esikhathini esizayo.
Ubuchwepheshe bokuphulukisa ukukhanya kwe-UV LED
Ubuchwepheshe bokwelapha be-UV LED buyindlela yokuphrinta esebenzisa ama-diode e-UV-LED akhipha ukukhanya njengemithombo yokukhanya elaphayo.Inezinzuzo zokuphila isikhathi eside, amandla aphezulu, ukusetshenziswa kwamandla okuphansi, futhi akukho ukungcola (i-mercury).Uma kuqhathaniswa nomthombo wokukhanya we-UV ovamile (isibani se-mercury), ububanzi obuyi-spectral obuyingxenye ye-UV LED buncane kakhulu, futhi amandla azogxila kakhulu, ukukhiqiza ukushisa okuphansi, ukusebenza kahle kwamandla aphezulu, kanye nemisebe efanayo efanayo.Ukusetshenziswa komthombo wokukhanya we-UV-LED kunganciphisa ukumoshakala kwezinsiza zokunyathelisa futhi kunciphise izindleko zokunyathelisa, ngaleyo ndlela konga isikhathi sokukhiqiza samabhizinisi okunyathelisa futhi kuthuthukise kakhulu ukusebenza kahle kokukhiqiza kwamabhizinisi.
Kuhle ukusho ukuthi ubuchwepheshe be-UV LED belapha busebenzisa ibhande le-ultraviolet eliphakathi kuka-365nm kuya ku-405nm, okungele-long wave ultraviolet (eyaziwa nangokuthi i-UVA band), ngaphandle kokulimala kwemisebe eshisayo, engenza ubuso be-UV. uyinki yome ngokushesha futhi uthuthukise ukucwebezela komkhiqizo.Ububanzi be-wavelength obusetshenziswa emkhakheni wokubulala amagciwane e-ultraviolet buphakathi kuka-190nm no-280nm, okungelebha emfushane ye-ultraviolet (eyaziwa nangokuthi ibhendi ye-UVC).Leli bhande lokukhanya kwe-UV ultraviolet lingabhubhisa ngokuqondile i-DNA kanye nesakhiwo se-RNA samangqamuzana namagciwane, futhi libangele ukufa okusheshayo kwama-microorganisms.
Ukusetshenziswa kobuchwepheshe bokwelapha be-UV LED ngabakhiqizi bangaphandle
I-Aztec Label, umholi wezobuchwepheshe be-MicroLED, umemezele ukuthi yakhe ngempumelelo futhi yafaka uhlelo lwayo lokumisa lwe-UV lwe-LED olukhulu kakhulu, oluzoshintsha ukukhiqizwa kwayo kwefekthri kuloluhlobo lobuchwepheshe ekupheleni konyaka.Ngemva kokufakwa ngempumelelo kwesistimu yokuqala yokwelapha ye-LED UV emshinini wokunyathelisa onemibala emibili ngonyaka odlule, inkampani ifaka uhlelo lwesibili lwe-Benford LED UV lokuphulukisa endlunkulu yayo eWest Midlands ukuze kuqhutshekwe nokunciphisa ukusetshenziswa kwamandla.
Imvamisa, ukusetshenziswa kobuchwepheshe bokuphrinta be-LED UV kungenza uyinki wome ngokuphazima kweso.Ukukhanya kwe-UV ye-LED yohlelo lwe-Aztec Label kungavulwa futhi kucishwe khona manjalo, asikho isikhathi sokupholisa esidingekayo, futhi senziwe nge-LED UV diode, ngakho-ke impilo yesevisi elindelekile yemishini yayo ingafinyelela emahoreni ayi-10,000-15,000.
Njengamanje, ukonga amandla kanye "nekhabhoni ekabili" kuba enye yezinkomba ezibalulekile zokuthuthukiswa kwezimboni ezinkulu.U-Colin Le Gresley, umphathi jikelele we-Aztec Label, naye ugqamise ukugxila kwenkampani kulo mkhuba, echaza ukuthi "ukusimama kuba umehluko oyinhloko wamabhizinisi kanye nesidingo esiyinhloko samakhasimende wokugcina".
U-Colin Le Gresley uphinde waveza ukuthi ngokwekhwalithi, imishini entsha ye-Benford Environmental LED UV ingaletha imiphumela yokuphrinta engabizi kanye nemibala egqamile, yenze ikhwalithi yokuphrinta izinze futhi ingabi namamaki.“Ngokombono wokusimama, idla amandla amancane kakhulu, ngaphansi kwamaphesenti angama-60 kunokomiswa kwe-UV okuvamile.Ngokuhambisana nokushintsha okusheshayo, ama-diode empilo ende kanye nekhabhoni yokushisa ephansi, iletha izinga eliphezulu elilindelwe ngamakhasimende, kuyilapho ihambisana kahle nemigomo yethu yokusimama.”
Kusukela kufakwe uhlelo lokuqala lwe-Benford, Ilebula ye-Aztec ihlatshwe umxhwele ngedizayini yayo elula, ephephile kanye nemiphumela yokusebenza.Njengamanje, inkampani inqume ukufaka isistimu yesibili, enkulu.
Isifinyezo
Okokuqala, ngokuvunywa kanye nokuqaliswa kwe "Minamata Convention" ngo-2016, ukukhiqizwa nokungenisa nokuthekelisa kwemikhiqizo equkethe i-mercury kuzovinjelwa kusukela ngo-2020 (iningi lokukhanyisa kwe-UV yendabuko lisebenzisa izibani ze-mercury).Ngaphezu kwalokho, ngoSepthemba 22, 2020, iChina yabeka isibonelo engqungqutheleni yama-75 yeNhlangano Yezizwe Ezihlangene yethula inkulumo mayelana “nenani eliphakeme lekhabhoni kanye nokungathathi hlangothi kwekhabhoni” amabhizinisi aseShayina azohlose ukunciphisa ukusetshenziswa kwamandla nokwenza ngcono ukusebenza kahle, futhi afezekise idijithali. kanye nezinguquko ezihlakaniphile zamabhizinisi.Ngokuthuthuka okuqhubekayo kobuchwepheshe bokunyathelisa kanye nokuthuthukiswa kokuvikelwa kwemvelo embonini yokunyathelisa esikhathini esizayo, ubuchwepheshe bokuphrinta be-UV-LED buzoqhubeka buvuthwa, okuzosiza imboni yokunyathelisa ukuthi iguqule futhi ithuthukise futhi ithuthuke ngamandla.
