Ngaba ukukhanya kwe-UVC kungayenza ingasebenzi iCoronavirus?

Abathengi banokufuna ukuthenga iibhalbhu ze-ultra-violet (UVC) zokucoca umphezulu wendlu okanye ezinye iindawo ezithelekisekayo ngenxa yobhubhani wangoku we-Coronavirus Sickness 2019 (COVID-19) esiziswe yi-coronavirus entsha i-SARS-CoV-2 

Yintoni isibane seUV?

Ukukhanya kwe-UV (i-ultraviolet) luhlobo lwemitha ye-electromagnetic. Inobude obufutshane kunokukhanya okubonakalayo, ngoko ke ayibonakali ngeso lenyama, kodwa inokubonwa ngempembelelo yayo kwizinto ezahlukeneyo. Imitha ye-UV inokutshintsha ibhondi yeekhemikhali kwiimolekyuli, ibangele ukusabela kweekhemikhali, kwaye inokubangela ukuba izinto ezininzi zibe fluoresce okanye zikhuphe ukukhanya. Imitha ye-UV ithoba ubume bekhonkco leepholima, okukhokelela ekulahlekelweni kwamandla kwaye mhlawumbi nokuguquka kwebala kunye nokuqhekeka. Ikwafunxwa zizidali-bala ezininzi kunye nedayi, ezibangela ukuba zitshintshe umbala. Ukukhanya kwe-UV  yenzeka ngokwendalo ekukhanyeni kwelanga kwaye inokukhutshwa yimithombo yokukhanya eyenziweyo.

Iintlobo zokukhanya kwe-UV ?

• UVA, okanye kufutshane UV (315–400 nm), ukukhanya kwe-UVA kunamandla aphantsi. Xa uselangeni, uboniswa ikakhulu kukukhanya kwe-UVA. Ukuvezwa kukukhanya kwe-UVA kudityaniswe nokuguga kwesikhumba kunye nomonakalo.
• UVB, okanye iUV ephakathi (280–315 nm), ukukhanya kwe-UVB kumbindi we-ultraviolet spectrum. Iqhezu elincinane lokukhanya kwelanga linokukhanya kweUVB. Lolona hlobo luphambili lwemitha ye-UV ebangela ukutshiswa lilanga kunye noninzi lomhlaza wolusu.

• UVC, okanye kude UV (180–280 nm), ukukhanya kwe-UVC kunamandla amaninzi. Uninzi lokukhanya kwe-UVC okuvela elangeni kutsalwa yi-ozone yoMhlaba, ngoko awuqhelekanga kuyo yonke imihla. Nangona kunjalo, kukho iintlobo ngeentlobo zemithombo ye-UVC eyenziweyo.

Ubude besibane bunokuba nefuthe kwindlela esinokuzenza ngayo zingasebenzi iintsholongwane kunye nokhuseleko kunye neenkxalabo zempilo ezinokuthi zibandakanyeke. Ukuvavanya isibane kunokutyhila ukuba kwaye kungakanani na ukukhupha amaza amaza ongezelelweyo. Ngokwesiqhelo, uluhlu lwamaza amaza oluncinane ngokwentelekiso lukhutshwa zii-LEDs. Ekubeni ii-LEDs zingenayo i-mercury, zinenzuzo ngaphezu koxinzelelo lwezibane zemercury eziphantsi 

Okwangoku, iimvavanyo zibonisa ukuba ukukhanya kwe-UVC lolona hlobo lusebenzayo lokukhanya kwe-ultraviolet ukubulala ibhaktheriya. Ingasetyenziselwa ukubulala iintsholongwane kumphezulu, umoya kunye nolwelo. Ukukhanya kwe-UVC kubulala iintsholongwane ezinjengeentsholongwane kunye neebhaktheriya ngokutshabalalisa iimolekyuli ezinjenge-nucleic acid kunye neeproteni. Oku kwenza ukuba kungenzeki ukuba ibhaktheriya ikwazi ukwenza iinkqubo eziyifunayo ukuze iphile.

Malunga nokuKhanya kwe-UVC kunye neNoveli yeCoronavirus

Inoveli coronavirus yavavanywa kwiinkcubeko zolwelo kusetyenziswa ukukhanya kwe-UVC kuphononongo lwakutsha nje olupapashwe kwiMagazini yaseMelika yoLawulo loSulelo.

Isibane seUVC soGutyulo loMphezulu

Olunye uphando oluxelwe kwi-AJIC luvavanywe kusetyenziswa isibane esithile se-UVC ukuphelisa i-SARS-CoV-2 kumphezulu walebhu. Ngokophononongo, imitha ye-UVC ibulale i-99.7% ye-coronavirus ephilayo phantsi kwemizuzwana engama-30.

Ukusebenzisa ukukhanya kwe-UVC ukuCoca umoya 

Uphononongo olwaphandwa kusetyenziswa ukukhanya okukude kwe-UVC ukuphelisa iindidi ezimbini zekoronavirus yabantu ngaphakathi koku UVC isifo somoya   kwijenali yenzululwazi yeeNgxelo zeNzululwazi.

UkuKhanya kwe-UVC yokubulala iintsholongwane kulwelo

  Uphononongo lwakutsha nje kwi-American Journal of Infection Control (AJIC) iphande ukusetyenziswa kokukhanya kwe-UVC ukubulala inani elikhulu lee-coronavirus zenoveli kwiinkcubeko zolwelo. Uphononongo lufumene ukuba imizuzu ye-9 yokukhanya kwe-UVC yokukhanya kwe-UVC ingayivula ngokupheleleyo intsholongwane.

Uzisebenzisa njani izibane ze-UVC ukubulala i-coronavirus

Amanzi, umoya, kunye neendawo ezithile kunzima ukuzicoca. Izibane ze-UVC zingasetyenziselwa ukubulala iintsholongwane kule ndawo. Umzekelo,  Izibane zeUVC kunye neerobhothi zisetyenziselwa ukubulala iintsholongwane emanzini, indawo kumagumbi esibhedlele angenanto, kunye nezithuthi ezinkulu ezifana neebhasi  Izibane zeUVC  ingasetyenziselwa kwiindawo ezivulekileyo ngaphakathi kwindlu ukuze ingasebenzi iintsholongwane zomoya kunye nezinye ii-microorganisms. Ukukhanyisa kufakwe phezulu kwegumbi ekuphakameni ubuncinane beenyawo ze-8 (i-2.4 yeemitha). I-engile ukuze ikhazimle ngokuthe tye okanye ibheke kwisilingi kunokuba ijonge emgangathweni. Iifeni kunye nezibane ziqinisekisa ukuba umoya uhamba ukusuka ezantsi kwegumbi ukuya phezulu kwaye ngokuchaseneyo. Ngokwenza oku, wonke umoya wegumbi ubonakaliswe  Izibane zeUVC , eyenza iintsholongwane ezisemoyeni zingasebenzi  Izibane zeUVC inokufakwa kwimibhobho yomoya ukuze ingasebenzi iintsholongwane ezihamba emoyeni kunye nezinye iibhaktheriya ezihamba ukusuka kwelinye igumbi ukuya kwelinye.

Kubalulekile ukuba  Izibane zeUVC  ezisetyenziswa kumagumbi nabantu musa hit igumbi. Ukukhanya kwakhe okuphezulu kwe-UVC kungonakalisa amehlo kunye nolusu ngemizuzwana nje.

Zeziphi iingxaki ezinaso izibane ze-UVC? 

Enye yeengxaki zayo kukuba ukukhanya kwe-UVC kufuna ukubamba ngokuthe ngqo ukuba kusebenze.

·  Akukaziwa ukuba zeziphi iiparamitha zokuvezwa kwe-UVC, ezinje nge-wavelength kunye nedosi, zisebenza kakhulu ekubulaleni i-SARS-CoV-2.

·  Amehlo akho okanye ulusu lwakho lunokonakala ukuba luvezwe kwiintlobo ezithile zokukhanya ze-UVC.

·  Izibane ezikhanyayo ze-UVC ezibonelelwa ukuba zisetyenziswe ekhaya zihlala zingenabunzulu obuncinci. Ngenxa yoko, ixesha elithathwayo ukutshabalalisa ibhaktheriya linokuba lide.

·  Imithombo yokukhanya ye-UVC inokudala i-ozone okanye i-mercury, enokwenzakalisa abantu.

Zeziphi iintlobo zezibane ezininzi ezinokukhupha i-UVC Radiation?

Nantsi inkcukacha ukuze wazi ukuba yintoni kanye eya kusebenza kuwe.

Isibane seMercury:

 Ngaphambili, imitha ye-UVC yayidla ngokuveliswa zizibane eziphantsi koxinzelelo lwemercury, eziphuma ubukhulu becala kwi-254 nm.>90%). Olu hlobo lwebhalbhu lunokwenza nolunye ubude bamaza. Ezinye izibane ziyafumaneka ezingavelisi ukukhanya okubonakalayo kunye ne-infrared kuphela kodwa kunye neentlobo ezininzi zamaza e-UV.

Ibhulb ye-Excimer okanye isibani esikude se-UVC:

Uhlobo oluthile lwesibane olunokukhutshwa okuphezulu malunga ne-222 nm kuthiwa "isibane se-excimer."

Izibabane zeXenon:

Ezi zibane, ezivelisa ukukhanya okufutshane kweUV, okubonakalayo, kunye nokukhanya kwe-infrared okuye kwalawulwa ukukhupha imitha ye-UVC ngokuyintloko, ngamaxesha athile zisetyenziswa ezibhedlele ukucoca imiphezulu kwiithiyetha kunye nezinye iindawo. Ezi ziqhele ukusetyenziswa xa kungekho bantu bakhoyo kwindawo.

I-Diodes yokukhanya ekhanya:

Kuya kuba lula ukufumana ii-LED ezikhupha imitha ye-UV. Ngokuqhelekileyo, uluhlu oluncinci lwe-wavelength lwemitha lukhutshwa zii-LEDs. Ekubeni ii-LEDs zingenayo i-mercury, zinenzuzo ngaphezu koxinzelelo lwezibane zemercury eziphantsi. Ii-LED zinokuthi ziqondiswe ngakumbi kwaye zibe nommandla omncinci.

Ungasithenga phi isibane seUV?

Ngoku, ufundile ukuba izibane ze-UVC zinefuthe elithile kwintsholongwane yesithsaba esitsha, kunye nokusetyenziswa  Izibane zeUVC yokubulala iintsholongwane mihla le.   Zhuhai Tianhui Electronic Co., Ltd  sisisombululo esigqibeleleyo ukuthenga eyakho  Izibane zeUVC . Ngo-2002 kwasekwa iZhuhai Tianhui Electronic Co., Ltd. Oku kugxilwe kwimveliso, ubugcisa obuphezulu Umvelisi we-UV Led  Iinkcukacha UVC isifo somoya Kwaye  Izibane zeUV Ukulungiselela uluhlu lwazo Isisombululo se-UV LED  Izicelo. Idibanisa uphando kunye nophuhliso, ukuvelisa, ukuthengisa, kunye Isisombululo se-UV LED Ukulungiselela.

Ummeli oyintloko kwi-Greater China yiSeoul Semiconductor SVC, kunye nentsebenziswano ethatha iminyaka engaphezu kweshumi. Iminyaka engamashumi amabini yamava abanzi ngaphakathi  UV LED  imarike, ulwazi lokusetyenziswa kwe  Izibane zeUV kumacandelo ahlukeneyo, kwaye ufanelekile ukubonelela abathengi ngophuhliso lwemveliso kunye nophando. Inokuphendula ngokukhawuleza kwizicelo zabathengi kwaye incede abathengi ekuhlalutyeni nasekusombululeni imiba okokuqala.

Amagama okugqibela

Uphononongo lubonise ukuba izibane ze-UVC zinokubulala ngempumelelo intsholongwane i-SARS-CoV-2 kumphezulu ukuya kuthi ga kwi-99.7%. I-UVC air disinfection ifakwe kwiinkqubo zokucoca eziqhelekileyo zizibhedlele ezininzi kunye namaziko ezonyango. Iiwadi zesibhedlele, iithiyetha, amagumbi otyando kunye nezixhobo zonyango ziyaxhamla kwi-UV air disinfection ukuze zigcinwe zicocekile kwaye zisuse iintsholongwane, kubandakanywa ii-superbugs ezithile ezixhathisa amayeza okubulala iintsholongwane. Ukucoca imihla ngemihla kunokusebenzisa izibane ze-UVC zokubulala iintsholongwane.
