Ingabe Ukukhanya kwe-UVC Kungayiyekisa I-Coronavirus?

Amakhasimende angase afune ukuthenga ama-ultra-violet (UVC) ukuze ahlanze izindawo ezisendlini noma ezinye izindawo ezifanayo uma kubhekwa umqedazwe wamanje we-Coronavirus Sickness 2019 (COVID-19) olethwe yi-coronavirus entsha i-SARS-CoV-2 

Kuyini Ukukhanya kwe-UV?

Ukukhanya kwe-UV (ultraviolet) kuwuhlobo lwemisebe kagesi. Inobude beza obufushane kunokukhanya okubonakalayo, ngakho ayibonakali ngeso lenyama, kodwa ingabonwa ngomphumela wayo ezintweni ezihlukahlukene. Imisebe ye-UV ingashintsha izibopho zamakhemikhali kuma-molecule, ibangele ukusabela kwamakhemikhali, futhi ingabangela izinto eziningi ukuba zikhanyise noma zikhiphe ukukhanya. Imisebe ye-UV ilulaza ukwakheka kweketango lama-polymer, okuholela ekulahlekelweni kwamandla futhi mhlawumbe nokuguquka kombala nokuqhekeka. Iphinde imuncwe ama-pigment amaningi kanye nodayi, okubenza bashintshe umbala. Ukukhanya kwe-UV  zenzeka ngokwemvelo ekukhanyeni kwelanga futhi zingabuye zikhishwe imithombo yokukhanya yokwenziwa.

Izinhlobo zokukhanya kwe-UV ?

• I-UVA, noma eduze kwe-UV (315–400 nm), ukukhanya kwe-UVA kunamandla aphansi kakhulu. Uma uselangeni, uchayeka ekukhanyeni kwe-UVA. Ukuchayeka ekukhanyeni kwe-UVA kuxhunyaniswe nokuguga kwesikhumba kanye nokulimala.
• I-UVB, noma i-UV ephakathi (280–315 nm), ukukhanya kwe-UVB kuphakathi kwe-ultraviolet spectrum. Ingxenye encane yokukhanya kwelanga iqukethe ukukhanya kwe-UVB. Iwuhlobo oluyinhloko lwemisebe ye-UV ebanga ukushiswa yilanga kanye nomdlavuza wesikhumba omningi.

• I-UVC, noma i-UV ekude (180–280 nm), ukukhanya kwe-UVC kunamandla amaningi. Iningi lokukhanya kwe-UVC okuvela elangeni limuncwa i-ozone Yomhlaba, ngakho-ke awuvamisile ukuchayeka kukho nsuku zonke. Kodwa-ke, kunezinhlobonhlobo zemithombo ye-UVC yokwenziwa.

Ubude begagasi besibani bungaba nomthelela ekutheni lingawavala kanjani amagciwane kanye nokuphepha kanye nokukhathazeka kwezempilo okungase kuhileleke. Ukuhlola isibani kungembula ukuthi ikhipha noma yimaphi amaza amaza engeziwe. Ngokuvamile, uhla lwamaza wamaza amaza oluncane uma kuqhathaniswa lukhishwa ama-LED. Njengoba ama-LED awanayo i-mercury, anenzuzo ngaphezu kwamalambu e-mercury anengcindezi ephansi 

Njengamanje, ucwaningo lufakazela ukuthi ukukhanya kwe-UVC kuwuhlobo olusebenza kahle kakhulu lokukhanya kwe-ultraviolet ukubulala amagciwane. Ingasetshenziselwa ukubulala amagciwane endaweni, umoya noketshezi. Ukukhanya kwe-UVC kubulala amagciwane afana namagciwane namagciwane ngokubhubhisa ama-molecule afana nama-nucleic acid namaprotheni. Lokhu kwenza amagciwane angakwazi ukwenza izinqubo azidingayo ukuze aphile.

Mayelana ne-UVC Light kanye neNovel Coronavirus

I-coronavirus yenoveli ihlolwe emasikweni oketshezi kusetshenziswa ukukhanya kwe-UVC ocwaningweni lwakamuva olushicilelwe ku-American Magazine of Infection Control.

Isibani se-UVC sokuThuthukiswa kweNhlanzeko ebusweni

Olunye ucwaningo olubikwe ku-AJIC luhlolwe kusetshenziswa isibani esithile se-UVC ukuqeda i-SARS-CoV-2 ezindaweni zelebhu. Ngokocwaningo, imisebe ye-UVC ibulale u-99.7% we-coronavirus ephilayo ngaphansi kwemizuzwana engama-30.

Ukusebenzisa ukukhanya kwe-UVC Ukuhlanza Umoya 

Ucwaningo olwaphenywa kusetshenziswa ukukhanya okukude kwe-UVC ukuqeda izinhlobo ezimbili zama-coronavirus abantu ngaphakathi kwalokhu Ukubulala umoya we-UVC   kujenali yesayensi Imibiko Yesayensi.

I-UVC Light yokubulala amagciwane oketshezi

  Ucwaningo lwakamuva ku-American Journal of Infection Control (AJIC) luphenye ukusetshenziswa kokukhanya kwe-UVC ukubulala inani elikhulu lama-coronavirus emasikweni oketshezi. Ucwaningo luthole ukuthi imizuzu engu-9 ye-UVC light irradiation ingaliyekisa ngokuphelele igciwane.

Ungazisebenzisa Kanjani Izibani ze-UVC Ukubulala ICoronavirus

Amanzi, umoya, nezindawo ezithile nezindawo kunzima ukuzihlanza. Izibani ze-UVC zingasetshenziswa ukubulala amagciwane kulezi zindawo. Isibonelo,  Izibani ze-UVC kanye namarobhothi asetshenziselwa ukubulala amagciwane emanzini, izindawo ezingaphezulu emakamelweni asesibhedlela angenalutho, kanye nezimoto ezinkulu njengamabhasi  Izibani ze-UVC  ingasetshenziswa ezindaweni ezivulekile ngaphakathi endlini ukuze yenze amagciwane ahamba emoyeni kanye nezinye izinto ezincane. Ukukhanyisa kufakwa phezulu kwekamelo endaweni ephakeme okungenani ngamamitha angu-2.4 (amamitha angu-2.4). I-engeli ukuze ikhanye ivundlile noma ibheke ophahleni kunokuba ibheke phansi. Amafeni nezibani ziqinisekisa ukuthi umoya uhamba usuka phansi wegumbi uye phezulu futhi ngokuphambene nalokho. Ngokwenza lokhu, wonke umoya osegumbini uvezwa kuwo  Izibani ze-UVC , okwenza amagciwane asemoyeni asebenze  Izibani ze-UVC ingabuye ifakwe emiseleni yomoya ukuze yenze amagciwane ahamba emoyeni namanye amagciwane asuke kwelinye igumbi aye kwelinye.

Kubalulekile ukuthi  Izibani ze-UVC  esetshenziswa emakamelweni nabantu musa hit the room. Ukukhanya kwakhe okuphezulu kwe-UVC kungalimaza amehlo nesikhumba ngemizuzwana nje.

Yiziphi Izinkinga Ezinawo Izibani ze-UVC? 

Enye yezingqinamba zayo ukuthi ukukhanya kwe-UVC kudinga ukuthinta okuqondile ukuze kusebenze.

·  Okwamanje akwaziwa ukuthi yimaphi amapharamitha wokuvezwa kwe-UVC, njengobude beza nomthamo, asebenza kahle kakhulu ekubulaleni i-SARS-CoV-2.

·  Amehlo akho noma isikhumba singalimala uma sichayeka ezinhlotsheni ezithile zokukhanya ze-UVC.

·  Izibani ezikhanyayo ze-UVC ezinikezwa ukuthi zisetshenziswe ekhaya zivame ukuba namandla amancane. Ngenxa yalokho, isikhathi esisithathayo ukubhubhisa amagciwane singase sibe side.

·  Imithombo yokukhanya ye-UVC ingase idale i-ozone noma i-mercury, engalimaza abantu.

Yiziphi Izinhlobo Eziningi Zezibani Ezingase Zikhiphe I-UVC Radiation?

Nansi imininingwane ukuze wazi ukuthi yini ezokusebenzela kahle.

Isibani Se-Pressure Mercury:

 Esikhathini esedlule, imisebe ye-UVC yayivame ukukhiqizwa amalambu e-mercury anengcindezi ephansi, ephuma kakhulu ku-254 nm (>90%). Lolu hlobo lwesibani lungaphinda lukhiqize amanye amaza amaza. Amanye amalambu ayatholakala angakhiqizi kuphela ukukhanya okubonakalayo ne-infrared kodwa namaza ahlukahlukene e-UV.

I-Excimer Bulb noma i-Far-UVC:

Uhlobo oluthile lwesibani olunokukhishwa okuphezulu okungaba ngu-222 nm lubizwa ngokuthi "isibani se-excimer."

Izilabhu ze-Pulse Xenon:

Lezi zibani, ezikhiqiza ukukhanya okufushane kwe-UV, okubonakalayo, kanye nokukhanya kwe-infrared okuye kwalawulwa ukuze kukhishwe imisebe ye-UVC ngokuyinhloko, ngezinye izikhathi zisetshenziswa ezibhedlela ukuhlanza izindawo ezinkundleni zemidlalo yaseshashalazini nakwezinye izindawo. Lezi zivame ukusetshenziswa uma kungekho abantu abakhona endaweni.

I-Diode Yokukhanyayo:

Kuya kuba lula futhi ukuthola ama-LED akhipha imisebe ye-UV. Imvamisa, uhla lwemisebe oluncane lwe-wavelength lukhishwa ama-LED. Njengoba ama-LED awanayo i-mercury, anenzuzo ngaphezu kwamalambu e-mercury anengcindezi ephansi. Ama-LED angase aqondiswe kakhulu futhi abe nendawo encane.

Ungathenga kuphi ukukhanya kwe-UV?

Manje, usufundile ukuthi izibani ze-UVC zinomthelela othile kugciwane lomqhele omusha, futhi zisebenzise  Izibani ze-UVC ukukhishwa kwamagciwane nsuku zonke.   Inkampani Zhuhai Tianhui Electronic Co., Ltd  yisixazululo esiphelele sokuthenga kwakho  Izibani ze-UVC . Ngo-2002 kwasungulwa iZhuhai Tianhui Electronic Co., Ltd. Lokhu kugxile ekukhiqizeni, kubuchwepheshe obuphezulu Umkhiqizi we-UV Led  Okukhethekile Ukubulala umoya we-UVC Kanye ne-  Izibani ze-UV Ukuhlinzekwa kobubanzi Isixazululo se-UV LED  Izicelo. Ihlanganisa ucwaningo nentuthuko, ukukhiqiza, ukuthengisa, kanye Isixazululo se-UV LED Ukuhlinzekela.

Ummeleli oyinhloko e-Greater China yi-Seoul Semiconductor SVC, ngokubambisana okuthatha iminyaka engaphezu kweshumi. Iminyaka engamashumi amabili yesipiliyoni esibanzi ngaphakathi kwe  UV LED  imakethe, ulwazi lokusebenzisa  Izibani ze-UV emikhakheni ehlukahlukene, futhi ifanelekele ukuhlinzeka amakhasimende ngokuthuthukiswa komkhiqizo nocwaningo. Ingakwazi ukuphendula ngokushesha izicelo zeklayenti futhi isize amakhasimende ekuhlaziyeni nasekuxazululeni izinkinga okokuqala ngqa.

Amagama Okugcina

Ucwaningo lukhombisile ukuthi izibani ze-UVC zingabulala ngempumelelo igciwane i-SARS-CoV-2 endaweni efinyelela ku-99.7%. Ukubulala amagciwane kwe-UVC emoyeni kufakwe ezinqubweni ezijwayelekile zokuhlanza izibhedlela eziningi nezikhungo zezokwelapha. Amawodi ezibhedlela, amagumbi okuhlinza, amagumbi okuhlinza nemishini yezokwelapha ayazuza ekubulaweni komoya kwe-UV ukuze agcinwe ehlanzekile futhi asuse amagciwane, okuhlanganisa nama-superbugs athile amelana nama-antibiotic. Ukuhlanza nsuku zonke kungasebenzisa namalambu e-UVC ukuze kubulawe amagciwane.
