On February 27, Hong Kong reported that the number of newly confirmed cases in a single day exceeded 20,000, reaching a new high. In an exclusive interview with the media, Feng Zijian, an expert who participated in guiding the mainland's aid to Hong Kong in the fight against the epidemic, and vice president and secretary-general of the Chinese Association of Preventive Medicine, emphasized that the current epidemic of new coronary pneumonia in Hong Kong is still accelerating, and various measures have been taken to try to suppress the upcoming epidemic. The peak has become the top priority of Hong Kong's anti-epidemic work.
According to the findings of "Expert Says UV", in order to better control the epidemic, the Hong Kong Food and Environmental Hygiene Department announced on the 23rd that it is following up the installation of ultraviolet UVC disinfection devices on escalator handrails in markets, cooked food markets and cooked food centers.

Experts said that UV has also observed that due to the epidemic situation in the past two years, except for the installation of UVC devices on escalators in markets, "escalator infection incidents and policy requirements" all indicate the importance of escalator disinfection, which is different from the past. Manual cleaning can further improve the efficiency of disinfection and block the risk of transmission.
Nws yog ib nqi sau cia hais tias raws li tam sim no layout ntawm escalators nyob rau hauv kev ua lag luam, UVC sterilization cov cuab yeej tsis yog tsuas yog siv nyob rau hauv kev lag luam thiab kev lag luam, tab sis kuj nyob rau hauv cov tsev qiv ntawv, khw malls, tsev so, railway chaw nres tsheb, tshav dav hlau, ntev - nrug Chaw nres tsheb neeg caij tsheb, thiab lwm yam. Cov chaw loj, xws li tsib lub tshav dav hlau loj hauv tsev, tau siv UVC sterilization, raws li hauv qab no:
Xyoo 2020, Changchun Longjia International Tshav Dav Hlau yuav teeb tsa cov cuab yeej tiv thaiv kab mob ultraviolet ntawm cov nce toj thiab taug kev mus.
Thaum Lub Rau Hli 2021, Hohhot Tshav Dav Hlau tau ua tiav cov cuab yeej tshuaj tua kab mob rau cov neeg caij tsheb kauj vab, hloov los ntawm cov tshuaj tua kab mob mus rau tiag tiag - sijhawm tua kab mob.
Thaum Lub Yim Hli 2021, Beijing Daxing Tshav Dav Hlau tau xaiv los nruab nrog cov cuab yeej siv tshuaj tua kab mob ultraviolet.
Thaum lub Cuaj Hlis 2021, Guangzhou Baiyun International Tshav Dav Hlau tau nthuav tawm tus kheej - tsim cov khoom siv tshuaj tua kab mob ultraviolet hauv Terminal 1, siv 265nm wavelength ultraviolet LED hluav taws xob rau kom tsis muaj menyuam.
In December 2021, 50 escalators (including moving walks) in the main passenger flow of the terminal building of Xi'an Xianyang International Airport will be equipped with handrail ultraviolet sterilization devices.
Terminal manufacturers tau koom nrog kev sib tw ua lag luam
Raws li QYResearch cov ntaub ntawv, lub lag luam escalator yuav tsum ncav cuag 35 billion yuan nyob rau hauv 2026, nrog ib tug compound txhua xyoo kev loj hlob tus nqi (CAGR) ntawm 3.7 feem pua. Tam sim no, ntau yam zoo -cov tuam txhab ua haujlwm of elevator tau nkag mus rau hauv kev ua lag luam. Piv txwv li, Toshiba Elevator tso tawm TG series ntawm escalators nrog UV LED sterilization muaj nuj nqi, nrog kwv yees muag ntim ntawm 250 units ib xyoo. Nws tau nkag siab tias ntxiv rau qhov kev saib xyuas tej thaj chaw deb kom tiv thaiv lub tiab ntev los ntawm kev clamped, lub elevator kuj ntxiv UV-LED sterilization ntaus ntawv uas tam sim no nrov tshaj plaws.
Raws li nws cov lus qhia, UVC-LED tuaj yeem siv los teeb pom kev txav ntawm tes thaum lub escalator khiav, thiab 99 feem pua ntawm cov tes taw txav tuaj yeem ua kom tsis muaj menyuam hauv li 30 feeb. Xav txog kev nyab xeeb ntawm cov neeg siv, lub sterilizer yog nruab rau hauv lub escalator, xws li cov folding ib feem ntawm lub tes tuav.
Hitachi Elevator kuj tau teeb tsa UV irradiation cov cuab yeej nrog lub wavelength ntawm 270285nm nyob rau hauv lub escalator kom tsis muaj menyuam cov tes tuav thiab cov kauj ruam hauv lub sijhawm, txo qhov kev pheej hmoo ntawm kev hla - kis kab mob thiab kab mob hauv thaj chaw muaj neeg coob.
Cov tuam txhab nruab nrab - thiab cov chaw nruab nrab no muaj lub sijhawm
Nws tau nkag siab tias tam sim no muaj ob txoj hauv kev tseem ceeb kom tau txais UVC rau kev ua kom tsis muaj menyuam thiab tshuaj tua kab mob: cov teeb mercury tsoos thiab ultraviolet LEDs. Piv nrog rau cov teeb mercury ib txwm muaj, UVC-LEDs maj mam hloov cov mercury teeb nrog cov txiaj ntsig zoo xws li cov khoom siv me me, tsis yog- tshuaj lom, lub neej ntev thiab siv tau yooj yim.
According to the "2021 UVC-LED Industry Research White Paper" jointly compiled by the industry research center and a number of enterprises, UVC-LED has a complete industrial chain, similar to the traditional LED industry chain, which can be mainly divided into chips, packages/molds Group, downstream terminal applications and other fields.
Nyob rau hauv cov nqe lus ntawm UVC -LED upstream nti manufacturing, muaj cov tuam txhab loj xws li Guangli Technology, Sanan Optoelectronics, Yuanrong Jason, Zhongke Luan, Shenzi Technology, Huacan Optoelectronics, Zhixin Semiconductor, Anxinmei Semiconductor thiab hais txog.
Nyob rau hauv nruab nrab ntawm UVC-LED, ntim thiab modules kuj tseem ua kom cov txheej txheem nrawm, feem ntau suav nrog Seoul Viosys, GMKJ LED thiab lwm lub tuam txhab.
"Experts say UV" believes that in the long run, the regularization trend of the new crown epidemic will increase people's daily demand for virus killing, and UVC killing equipment will replace traditional sterilization methods in the future, which will promote the volume of UVC-LED killing equipment.
