Tsis ntev los no, Shanghai Consumer Rights Protection Committee tau ua qhov kev sim sib piv ntawm 25 cov khoom siv hluav taws xob kom qhuav uas thov kom muaj kev ua kom tsis muaj menyuam thiab tsis muaj menyuam kom zoo los ntsuas seb lawv puas muaj kev tshaj tawm kom tsis muaj menyuam. Hom no" ntse kom tsis muaj menyuam kom qhuav" yog nyiam los ntawm cov neeg nyiam hauv tsev. Lub ntsiab muag tseem ceeb yog kev ua kom tsis muaj menyuam ntawm cov khaub ncaws. Feem ntau ntawm nws txoj cai ua kom tsis muaj menyuam vam khom lub teeb ci ultraviolet kom ua tiav kev ua kom tsis muaj menyuam.
Qhov tseeb, sai li sai tau kis mob sib kis, UVC-LED cov khoom lag luam ntawm lub khw tau sib xyaw ua ke, xws li&"muag B cov khoom lag luam raws li Cov khoom lag luam &";,&"; 70% UVC sib xyaw nrog 30% UVA&";, uas ua ke nrog International Cov Neeg Siv Khoom Txoj Cai Hnub ntawm 3.15. Ua qhov xwm txheej ntawm lub ntsej muag kom tsis muaj menyuam kom qhuav ua piv txwv. UV Science yuav qhia koj cov txiaj ntsig kev xeem.
Cov txiaj ntsig ntawm qhov kev ntsuas no qhia tias 2 ntawm lub teeb ci ultraviolet nyob hauv UVC band thiab 23 nyob hauv UVA band. Ze li ib nrab ntawm cov qauv UV teeb tau teeb tsa ua haujlwm li 20 txog 30 feeb, uas nyuaj rau ua tiav qhov ua kom tsis muaj menyuam zoo. Qhov ua kom tsis muaj menyuam ntawm lub teeb UV nyob ntawm nws lub dav hlau, thaj chaw hluav taws xob, qhov tshuaj tiv thaiv hluav taws xob thiab lub sijhawm hluav taws xob.
Los ntawm qhov pom ntawm cov qhab nthwv dej, cov neeg sab hauv paub tias qhov ua kom muaj kab mob tua kab mob ultraviolet ntawm UVA band tsis muaj zog dua li ntawm UVC band, thiab lub sijhawm ua kom tsis muaj menyuam ntev dua. Feem ntau nws siv sijhawm ntau dua 8 teev ntawm kev tso hluav taws xob kom muaj qee yam tshuaj tua kab mob/tua kab mob. Tam sim no, tsis yog txhua lub tshuab ziab khaub ncaws kom qhuav los ntawm ultraviolet lub teeb ntawm kev ua lag luam siv UVC-LED, thiab cov neeg siv khoom yuav tsum paub qhov txawv kom meej meej thaum yuav khoom. Qhov ntawd yog yuav tsum tau them nyiaj tshwj xeeb rau ob lub ntsiab lus:
1) Yog tias muaj UVA-LED (320-405nm) hauv qhov kev yoj yoj yoj yoj, nws puas yog lub ntsiab nthwv dej kom tsis muaj menyuam, lossis lub teeb liab tsis muaj zog tuaj yeem tawm nrog kev pab ntawm 405 waveband, uas yog siv los pab UVC-LED los qhia seb nws puas ua haujlwm zoo; yog tias nws yog Lub ntsiab kom tsis muaj menyuam tsis tu ncua yog UVA-LED, yog li lub sijhawm ntev yuav tsum tau txiav txim siab.
2) Nws yog qhov zoo tshaj plaws los yuav cov khoom lag luam tsim los ntawm cov tuam txhab lag luam uas muaj ntawv pov thawj xws li CGI, SGS, TUV, thiab Tuam Tsev Tuam Tsev Siv Hluav Taws Xob Tuam Tsev.
Cov Lus Qhia: Ua tib zoo saib cov ntsiab lus hauv qab no thaum siv lub tshuab ziab khaub ncaws kom qhuav nrog lub tshuab ua kom tsis muaj ultraviolet: teeb tsa nws ntawm lub sam thiaj sab nraum zoov lossis lub sam thiaj cais lub cev; siv ultraviolet kom tsis muaj menyuam ua haujlwm raws li cov lus piav qhia khoom; tsis txhob saib ncaj qha rau ntawm lub teeb ci, thiab txwv tsis pub cov neeg ua haujlwm, tshwj xeeb yog menyuam yaus tshwm hauv thaj tsam ntawm ultraviolet teeb; qhib lub qhov rais kom tso cua tom qab tsis muaj menyuam; tawv, txhob lo lo ntxhuav thiab lwm cov ntaub thiab cov khaub ncaws uas muaj xim zoo nkauj tsis haum rau kom tsis muaj menyuam nyob hauv qab lub teeb ci ultraviolet.
UVC-LED kom tsis muaj menyuam muaj nws tus kheej xav tau thiab cov hau kev siv. Qhov muag tsis pom kev ntawm gimmicks yuav tsis tsuas yog stigmatize qhov ua tau zoo ntawm UVC-LED kom tsis muaj menyuam, tab sis kuj pov tseg cov peev txheej. Hauv tsab xov xwm dhau los, peb twb tau qhia rau koj hauv kev nthuav dav yuav txheeb xyuas seb UVC-LED cov khoom lag luam zoo thiab nyab xeeb li cas. Tsuas yog ua raws cov cai tshwj xeeb ntawm UVC-LED tuaj yeem UVC-LED dhau los ua riam phom zoo rau kev tiv thaiv kev noj qab haus huv.
Yav dhau los, UV Science tau tham nrog koj seb UVC-LED puas haum rau ib puag ncig hauv tsev, thiab hais tawm qhov kev xav ntawm cov thawj coj hauv kev lag luam. Yog xav paub ntxiv, thov nyem [Lub teeb ultraviolet tsis haum rau siv hauv tsev? Mloog cov lus pom zoo ntawm cov kws tshaj lij no! 】
Kev rov tua tsis tau txiaj ntsig ntawm UVC-LED qhia peb:
Rau cov tuam txhab tsim khoom hauv kev lag luam: nws yuav tsum nco ntsoov tias kev loj hlob ntawm UVC-LED kev lag luam tsuas tuaj yeem vam khom cov thev naus laus zis txuas mus ntxiv thiab tsim cov khoom tsim nyog los siv UVC-LED cov khoom lag luam hauv cov xwm txheej uas tsim nyog rau lawv lub zog tam sim no thiab kev ua haujlwm tau zoo. Tsuas yog los ntawm kev ua kom tsis muaj menyuam tsis muaj txiaj ntsig ntawm nws cov khoom tuaj yeem lees paub thiab txhawb nqa los ntawm cov pej xeem. Kuv ntseeg tias nrog kev koom tes ze ntawm cov tuam txhab tsim khoom nqes thiab nqes hav, kev lag luam yuav tuaj yeem txhawb kev txhim kho sai dua thiab coj cov neeg siv khoom siv tau zoo dua thiab nyab xeeb cov khoom siv tshuaj tua kab mob.
