Ukulwa nobhubhane! Kuzoba isenzo esihlangene sabantu bonke eMkhosini Wentwasahlobo ka-2020. Ngemva kokubona “isimbozo” okunzima ukusithola nokugcotshwa nguShuanghuanglian namanye amahlaya, iqembu lethu labangane lagxila kancane kancane esibanini sokubulala amagciwane se-UV.
Ngakho-ke i-coronavirus entsha ingabulawa isibani se-ultraviolet？
Uhlelo lokuxilongwa nokwelashwa kwe-coronavirus pneumonia (inguqulo yesilingo) olushicilelwe ohlelweni lwesine lweNational Health Protection Commission kanye ne-State Administration of traditional Chinese medicine luthi leli gciwane liyazwela ku-ultraviolet kanye nokushisa, futhi izinga lokushisa liphakeme ngemizuzu engama-56 imizuzu engama-30. I-Ether, i-ethanol engama-75%, isibulala-magciwane se-chlorine, i-peracetic acid kanye ne-chloroform kungawuqeda ngempumelelo leli gciwane. Ngakho-ke, isibani sokubulala amagciwane se-ultraviolet siyasebenza ekubulaleni igciwane.
I-UV ingahlukaniswa ibe yi-UV-A, UV-B, UV-C kanye nezinye izinhlobo ngokuya ngobude be-wavelength. Izinga lamandla liyakhula kancane kancane, futhi ibhendi ye-UV-C (100nm ~ 280nm) ivame ukusetshenziselwa ukubulala amagciwane kanye nokubulala amagciwane.
Isibani sokubulala amagciwane se-Ultraviolet sisebenzisa ukukhanya kwe-ultraviolet okukhishwa yilambu le-mercury ukuze kufezwe umsebenzi wokubulala amagciwane. Ubuchwepheshe bokubulala amagciwane be-Ultraviolet bunokusebenza kahle kokubulala amagciwane okungenakuqhathaniswa uma kuqhathaniswa nobunye ubuchwepheshe, futhi ukusebenza kahle kokubulala amagciwane kungafinyelela ku-99% ~ 99.9%. Umgomo waso wesayensi ukusebenza ku-DNA yama-microorganisms, ukubhubhisa isakhiwo se-DNA, nokuwenza alahlekelwe umsebenzi wokuzala nokuziphindaphinda, ukuze kufezwe injongo yokubulala amagciwane.
Ingabe isibani sokubulala amagciwane se-ultraviolet siyingozi emzimbeni womuntu? Ukubulala amagciwane kwe-ultraviolet kunezinzuzo zokungabi nambala, ukungabi nambitheki futhi okungenamakhemikhali asele ngemuva, kodwa uma kungekho zindlela zokuzivikela ezisetshenziswayo, kulula kakhulu ukubangela umonakalo omkhulu emzimbeni womuntu.
Isibonelo, uma isikhumba esiveziwe sikhanyiswe yilolu hlobo lokukhanya kwe-ultraviolet, ukukhanya kuzovela ukubomvu, ukulunywa, ukubola; okubi kakhulu kuzodala ngisho nomdlavuza, izimila zesikhumba njalo njalo. Ngesikhathi esifanayo, futhi “kungumbulali ongabonakali” wamehlo, okungabangela ukuvuvukala kwe-conjunctiva kanye ne-cornea. Ukukhanya kwesikhathi eside kungaholela ku-cataract. I-ultraviolet nayo inomsebenzi wokubhubhisa amangqamuzana esikhumba somuntu, okwenza isikhumba siguge ngaphambi kwesikhathi. Esikhathini esingavamile samuva nje, amacala omonakalo obangelwa ukusetshenziswa okungafanele kwesibani sokubulala amagciwane se-ultraviolet avame kakhulu.
Ngakho-ke, uma uthenga isibani sokubulala amagciwane se-ultraviolet ekhaya, kufanele ukhumbule uma usisebenzisa:
1. Uma usebenzisa isibani sokubulala amagciwane se-ultraviolet, abantu, izilwane nezitshalo kumele bashiye indawo;
2. Amehlo akufanele abheke isibani sokubulala amagciwane se-ultraviolet isikhathi eside. Imisebe ye-ultraviolet inomonakalo othile esikhumbeni somuntu kanye nolwelwesi lwamafinyila. Uma usebenzisa isibani sokubulala amagciwane se-ultraviolet, kufanele unake ukuvikelwa. Amehlo akufanele abheke ngqo umthombo wokukhanya kwe-ultraviolet, kungenjalo amehlo azolimala;
3. Uma usebenzisa isibani sokubulala amagciwane se-ultraviolet ukubulala amagciwane ezintweni, sakazeka noma ulengise izinto, wandise indawo yokukhipha imisebe, ibanga elisebenzayo liyimitha elilodwa, kanti isikhathi sokukhipha imisebe cishe imizuzu engama-30;
4. Uma usebenzisa isibani sokubulala amagciwane se-ultraviolet, indawo ezungezile kufanele igcinwe ihlanzekile, futhi akufanele kube nothuli namanzi emoyeni. Uma izinga lokushisa langaphakathi lingaphansi kuka-20 ℃ noma umswakama ohlobene ungaphezu kuka-50%, isikhathi sokuchayeka kufanele sandiswe. Ngemva kokuhlanza umhlabathi, uwuhlanze ngesibani se-ultraviolet ngemva kokuba umhlabathi womile;
5. Ngemva kokusebenzisa isibani sokubulala amagciwane se-ultraviolet, khumbula ukufaka umoya imizuzu engama-30 ngaphambi kokungena egumbini. Okokugcina, siphakamisa ukuthi uma umndeni wakho ungakamxilongi isiguli, ungasihlanzisi imithi yasekhaya. Ngoba akudingeki sibulale wonke amabhaktheriya noma amagciwane empilweni yethu, futhi indlela ephumelela kakhulu yokuvimbela ukutheleleka okusha kwe-coronavirus ukuphuma kancane, ukugqoka imaski nokugeza izandla njalo.
