Ukulwa nobhubhane! Kuya kuba sisenzo esidibeneyo sabantu bonke kwiNtwasahlobo yoMnyhadala ka-2020. Emva kokubona “isigqubuthelo” esinzima ukufumaneka nokucocwa nguShuanghuanglian kunye nezinye iziqhulo, iqela lethu labahlobo lagxila kancinci kancinci kwisibane sokubulala iintsholongwane se-UV.
Ngoko ke i-coronavirus entsha inokubulawa sisibane se-ultraviolet？
Isicwangciso sokuxilongwa kunye nonyango lwe-coronavirus pneumonia (uhlobo lovavanyo) olupapashwe kuhlelo lwesine lweKhomishini yoKhuseleko lwezeMpilo yeSizwe kunye noLawulo lweSizwe lwamayeza emveli aseTshayina lukhankanye ukuba intsholongwane inovelwano kwi-ultraviolet kunye nobushushu, kwaye ubushushu buphezulu ngemizuzu engama-56 imizuzu engama-30. I-Ether, i-75% ye-ethanol, isibulali-ntsholongwane se-chlorine, i-peracetic acid kunye ne-chloroform zinokuyicima ngempumelelo intsholongwane. Ke ngoko, isibane sokubulala iintsholongwane se-ultraviolet siyasebenza ekubulaleni intsholongwane.
I-UV inokwahlulwa ibe yi-UV-A, i-UV-B, i-UV-C kunye nezinye iintlobo ngokobude bobude bomda. Inqanaba lamandla liyakhula kancinci kancinci, kwaye ibhendi ye-UV-C (100nm ~ 280nm) isetyenziswa ngokubanzi ekubulaleni iintsholongwane nasekubulaleni iintsholongwane.
Isibane sokubulala iintsholongwane se-Ultraviolet sisebenzisa ukukhanya kwe-ultraviolet okukhutshwa sisibane se-mercury ukuze kufezekiswe umsebenzi wokubulala iintsholongwane. Itekhnoloji yokubulala iintsholongwane ye-Ultraviolet inokusebenza kakuhle kokubulala iintsholongwane xa ithelekiswa nezinye iiteknoloji, kwaye ukusebenza kakuhle kokubulala iintsholongwane kunokufikelela kwi-99% ~ 99.9%. Umgaqo wayo wesayensi kukusebenza kwi-DNA yeentsholongwane, ukutshabalalisa isakhiwo se-DNA, nokuzenza zilahlekelwe ngumsebenzi wokuzala nokuziphindaphinda, ukuze kufezekiswe injongo yokubulala iintsholongwane.
Ngaba isibane sokubulala iintsholongwane se-ultraviolet siyingozi emzimbeni womntu? Ukubulala iintsholongwane nge-ultraviolet kuneengenelo zokuba akukho mbala, akukho ncasa kwaye akukho khemikhali zishiyekileyo, kodwa ukuba akukho manyathelo okukhusela asetyenziswayo, kulula kakhulu ukubangela umonakalo omkhulu emzimbeni womntu.
Umzekelo, ukuba ulusu oluvezwe lukhanyiswe lolu hlobo lokukhanya kwe-ultraviolet, ukukhanya kuya kubonakala kubomvu, ukurhawuzelela, ukubola; okunzulu kuya kubangela nomhlaza, iithumba zesikhumba njalo njalo. Kwangaxeshanye, kukwangu “mbulali ongabonakaliyo” wamehlo, okunokubangela ukudumba kwe-conjunctiva kunye ne-cornea. Ukukhanyiswa kwexesha elide kunokukhokelela kwi-cataract. I-ultraviolet ikwanomsebenzi wokutshabalalisa iiseli zesikhumba somntu, okwenza ulusu luguge ngaphambi kwexesha. Kwixesha lakutshanje elingaqhelekanga, iimeko zomonakalo obangelwa kukusetyenziswa gwenxa kwesibane sokubulala iintsholongwane se-ultraviolet zixhaphake kakhulu.
Ngoko ke, ukuba uthenga isibane sokubulala iintsholongwane se-ultraviolet ekhaya, kufuneka ukhumbule xa usisebenzisa:
1. Xa kusetyenziswa isibane sokubulala iintsholongwane se-ultraviolet, abantu, izilwanyana kunye nezityalo kufuneka bashiye indawo;
2. Amehlo akufuneki ajonge isibane sokubulala iintsholongwane se-ultraviolet ixesha elide. Imisebe ye-ultraviolet inomonakalo othile kulusu lomntu kunye ne-mucous membrane. Xa usebenzisa isibane sokubulala iintsholongwane se-ultraviolet, kufuneka kuqwalaselwe ukhuseleko. Amehlo akufuneki ajonge ngqo umthombo wokukhanya kwe-ultraviolet, kungenjalo amehlo aya kwenzakala;
3. Xa usebenzisa isibane sokubulala iintsholongwane se-ultraviolet ukubulala iintsholongwane kwizinto, sasaza okanye uxhome izinto, wandise indawo yokukhanyisela, umgama osebenzayo yimitha enye, kwaye ixesha lokukhanyisela malunga nemizuzu engama-30;
4. Xa usebenzisa isibane sokubulala iintsholongwane se-ultraviolet, indawo engqongileyo mayigcinwe icocekile, kwaye akufuneki kubekho uthuli kunye nenkungu yamanzi emoyeni. Xa ubushushu bangaphakathi bungaphantsi kwama-20 ℃ okanye umswakama ohambelanayo ungaphezulu kwama-50%, ixesha lokuvezwa kufuneka landiswe. Emva kokucoca umhlaba, wubulale ngesibane se-ultraviolet emva kokuba umhlaba womile;
5. Emva kokusebenzisa isibane sokubulala iintsholongwane se-ultraviolet, khumbula ukufaka umoya imizuzu engama-30 ngaphambi kokuba ungene kwigumbi. Okokugqibela, sicebisa ukuba ukuba usapho lwakho aluzange luxilonge isigulana, ungasibulali iintsholongwane kwiimveliso zasekhaya. Kuba akufuneki sibulale zonke iintsholongwane okanye iintsholongwane ebomini bethu, kwaye eyona ndlela isebenzayo yokuthintela usulelo olutsha lwe-coronavirus kukuphuma kancinci, ukunxiba iimaski kunye nokuhlamba izandla rhoqo.
