Tiv thaiv kev sib kis kab mob! Nws yuav dhau los ua kev sib koom tes ntawm tag nrho cov neeg hauv lub Caij Nplooj Ntoos Hlav Xyoo 2020. Tom qab ntsib "kev npog" nyuaj nrhiav thiab raug txhuam los ntawm Shuanghuanglian thiab lwm yam kev tso dag, peb cov phooj ywg maj mam tsom mus rau lub teeb UV tua kab mob.
Yog li tus kab mob coronavirus tshiab tuaj yeem tua tau los ntawm lub teeb ultraviolet?
Daim ntawv qhia txog kev kuaj mob thiab kho mob coronavirus pneumonia (kev sim ua qauv) uas tau luam tawm hauv tsab ntawv thib plaub ntawm National Health Protection Commission thiab State Administration of Chinese medicine tau hais tias tus kab mob no rhiab heev rau ultraviolet thiab cua sov, thiab qhov kub thiab txias yog 56 feeb siab rau 30 feeb. Ether, 75% ethanol, chlorine disinfectant, peracetic acid thiab chloroform tuaj yeem ua rau tus kab mob tsis ua haujlwm zoo. Yog li ntawd, lub teeb ultraviolet disinfection zoo rau kev tua tus kab mob.
UV muaj peev xwm muab faib ua UV-A, UV-B, UV-C thiab lwm hom raws li qhov ntev ntawm wavelength. Lub zog theem maj mam nce, thiab UV-C band (100nm ~ 280nm) feem ntau yog siv rau kev tua kab mob thiab kev ua kom tsis muaj menyuam.
Lub teeb tua kab mob ultraviolet siv lub teeb ultraviolet uas lub teeb mercury tso tawm los ua kom tiav kev ua haujlwm tua kab mob. Cov thev naus laus zis tua kab mob ultraviolet muaj kev ua haujlwm tua kab mob zoo tshaj plaws piv rau lwm cov thev naus laus zis, thiab kev ua haujlwm tua kab mob tuaj yeem ncav cuag 99% ~ 99.9%. Nws lub hauv paus ntsiab lus yog ua rau DNA ntawm cov kab mob me me, rhuav tshem cov qauv DNA, thiab ua rau lawv poob qhov kev ua haujlwm ntawm kev tsim tawm thiab kev rov ua dua tus kheej, yog li ua tiav lub hom phiaj ntawm kev tua kab mob.
Puas yog lub teeb tua kab mob ultraviolet muaj teeb meem rau tib neeg lub cev? Kev tua kab mob ultraviolet muaj qhov zoo ntawm tsis muaj xim, tsis muaj saj thiab tsis muaj tshuaj lom neeg tshuav tseg, tab sis yog tias tsis muaj kev tiv thaiv siv, nws yooj yim heev rau kev ua rau muaj kev phom sij rau tib neeg lub cev.
Piv txwv li, yog tias daim tawv nqaij raug tshav ntuj los ntawm lub teeb ultraviolet no, lub teeb yuav tshwm sim liab, khaus, desquamation; qhov hnyav yuav ua rau mob qog noj ntshav, qog tawv nqaij thiab lwm yam. Tib lub sijhawm, nws tseem yog "tus neeg tua neeg tsis pom" ntawm lub qhov muag, uas tuaj yeem ua rau o ntawm conjunctiva thiab cornea. Kev tshav ntuj ntev tuaj yeem ua rau cataract. Ultraviolet kuj muaj lub luag haujlwm ntawm kev rhuav tshem cov hlwb tawv nqaij ntawm tib neeg, ua rau daim tawv nqaij laus ua ntej lub sijhawm. Nyob rau lub sijhawm tsis ntev los no, cov xwm txheej ntawm kev puas tsuaj los ntawm kev siv tsis raug ntawm lub teeb ultraviolet disinfection yog ntau dua.
Yog li ntawd, yog tias koj yuav lub teeb tua kab mob ultraviolet hauv tsev, koj yuav tsum nco ntsoov thaum siv nws:
1. Thaum siv lub teeb tua kab mob ultraviolet, tib neeg, tsiaj txhu thiab nroj tsuag yuav tsum tawm hauv qhov chaw ntawd;
2. Qhov muag yuav tsum tsis txhob ntsia lub teeb ultraviolet ntev ntev. Lub teeb ultraviolet muaj qee yam kev puas tsuaj rau tib neeg daim tawv nqaij thiab cov ntaub so ntswg. Thaum siv lub teeb ultraviolet, yuav tsum tau ceev faj txog kev tiv thaiv. Qhov muag yuav tsum tsis txhob ntsia lub teeb ultraviolet ncaj qha, txwv tsis pub qhov muag yuav raug mob;
3. Thaum siv lub teeb tua kab mob ultraviolet los tua cov khoom, nthuav lossis dai cov khoom, nthuav thaj chaw irradiation, qhov deb zoo yog ib 'meter', thiab lub sijhawm irradiation yog li 30 feeb;
4. Thaum siv lub teeb tua kab mob ultraviolet, ib puag ncig yuav tsum huv si, thiab yuav tsum tsis txhob muaj hmoov av thiab dej nyob hauv huab cua. Thaum qhov kub hauv tsev qis dua 20 ℃ lossis qhov av noo ntau dua 50%, lub sijhawm raug yuav tsum ntev dua. Tom qab txhuam hauv av, tua kab mob nrog lub teeb ultraviolet tom qab hauv av qhuav;
5. Tom qab siv lub teeb tua kab mob ultraviolet, nco ntsoov ua kom cua nkag mus rau hauv chav li 30 feeb ua ntej nkag mus hauv chav. Thaum kawg, peb xav kom koj tsis txhob tua cov khoom siv hauv tsev. Vim tias peb tsis tas yuav tua tag nrho cov kab mob lossis cov kab mob hauv peb lub neej, thiab txoj hauv kev zoo tshaj plaws los tiv thaiv kev kis tus kab mob coronavirus tshiab yog tawm mus tsawg dua, hnav lub ntsej muag thiab ntxuav tes ntau zaus.
