Tshaj tawm thiab ua tau zoo UV cua kom tsis muaj menyuam nyob rau xyoo 2020

Sij hawm: 2020-07-09

Yuav kom tawm tsam nrog cov pa phem tshaj plaws, muaj ntau ntawm cov UV teeb ntawm cov lag luam tam sim no.


Cov kev sim, kev tshawb nrhiav, thiab ntau ntxiv tau ua tiav hauv ntau pua xyoo los ua huab cua huv thiab txhim kho qhov zoo. Tab sis lawv qhov kawg ua pov thawj tsis tau muaj txiaj ntsig.


Ntau cov thev naus laus zis zoo li UV mercury lossis UVC teeb tau hais tias muaj kev noj qab haus huv, tab sis lawv tsis ua haujlwm zoo li TiO2 photocatalyst nrog UV LED teeb.


Yog li, hauv tsab xov xwm no, peb yuav coj koj mus rau kev taug kev los ntawm tsawg dua mus rau cov thev naus laus zis zoo ntawm UV cua kom tsis muaj menyuam.


cua pa phem


1. UV Mercury Tube muaj kev phom sij rau kev noj qab haus huv


Peb txhua tus paub thiab nkag siab txog qhov txaus ntshai ntawm UV mercury teeb. Cov kis rau ib qib twg tuaj yeem tsim teeb meem ntau dua rau cov tawv nqaij kub hnyiab thiab qee zaum ua yog toog pom. Saib rau qhov txaus ntshai ntawm nws thiab muaj kev nyab xeeb thaum siv nws.


  • Mercury yog ib hom tshuaj lom neeg


Mercury ib txwm muaj cov tshuaj lom thiab nqus tau cov pa ua rau nws muaj kev puas tsuaj rau lub ntsws, lub raum, thiab lwm yam. Yog li, ib tus hauv lub teeb yuav ua rau qee qhov kev phom sij heev. Kev tsis nco qab, nco nco, mob taub hau, thiab ntau lwm yam teeb meem tuaj yeem cuam tshuam nrog qhov tseeb tias muaj mercury nyob hauv huab cua.


cov mob mercury


Txhawm rau kom nkag siab txog qib kev haus tshuaj lom, koj yuav xav tau los ua ib qho lus nug ntxiv thiab qhov ntawd yog:


  • Yuav ua li cas yog hais tias UV Mercury-muaj Lub Teeb Txhaum?


Txhua UV vapor teeb muaj kwv yees li 400 mg ntawm cov roj ntsha tseem ceeb. Yog li, yog tias nws tawg, mercury tuaj yeem tsim kev puas tsuaj rau lub qhov muag thiab tawv nqaij. Tej zaum nws tsuas yog los ntawm kev nqus tau thiab tsis muaj kev ncaj qha nrog cov mercury, tab sis nws tuaj yeem tsim teeb meem kev noj qab haus huv xws li hnoos, kub cev, ua pa nyuaj, mob taub hau, thiab lwm yam.


Tau paub txog kev puas tsuaj ntawm Mercury-muaj teeb coj peb mus rau UV-C coj teeb thiab LED teeb. Tom qab nrhiav pom qhov txaus ntshai ntawm UV, nws tau raug txiav txim siab tias yog tshuaj tua kab rau huab cua ntev ntev.


2. UVC LED Sawb tsis tshua muaj kev ua haujlwm


Kev lag luam UVC LEDs muaj nyob rau ntawm kev ua lag luam los ntawm ze 10 xyoo dhau los, qhov teeb meem loj ntawm cov coj no yog:


  • Rau Cov Zis Me Nyuam Cov Hwj Huam Me Me

UV feem UV sawv cev ntab tawm ntawm 200 nm-280 nm, nrog rau ntau yam ntawm 250 nm - 280 nm. Nws ntxuav cov kab mob thiab cov microbes, tab sis nyob rau hauv txoj kev txwv thiab tsis ua haujlwm zoo tshaj rau cov chaw loj.


  • Tsis Muaj Peev Xwm Penetration muaj peev xwm

Ua ntej koj xav tias UV-C teeb ua kev daws teeb meem zoo thiab sai sai, tab sis lawv tseem muaj lub zog tsim tsawg. Thiab qhov tsis tuaj yeem ncav cuag UV ntxoov ntxoo yog lwm qhov kev qias. Cov no yog cov cheeb tsam uas UV lub teeb tau sim los ntawm lwm yam khoom.


uv nqi


  • Muaj nqi

Ntxiv mus, UVC lub teeb tseem kim heev thiab thaum koj xav txog lwm yam tsis zoo ntawm nws, koj yuav paub tias nws tsis tsim nyog rau cov nyiaj uas koj siv rau nws.


3. Vim li cas UV LED + Photocatalyst txoj kev xaiv zoo tshaj plaws?


Txoj cai tam sim no ib puag ncig yog qhov kev txhawj xeeb tseem ceeb rau txhua qhov kev lag luam. Yog li, ntawm no yog qhov kev xaiv zoo tshaj plaws rau teeb. Raws li peb tau sim ntau lub thev naus laus zis rau huab cua thiab lawv kuj muaj lawv cov kev phiv ua rau muaj teeb meem ntau lossis tsis muaj zog ntawm lub qhov muag teev uas ua rau muaj teeb meem ntau dua.


Zoo, kev tshawb fawb thiab thev naus laus zis muaj ib qho zoo tshaj plaws thiab nws yog kev tshawb fawb kom txog thaum koj tau txais kev vam meej. Yog li, ntawm no los ntawm UV LED + Photocatalyst. Saib seb nws yog qhov kev xaiv zoo tshaj plaws li cas los txog tam sim no.


3.1 Photocatalysis yog dab tsi thiab nws ua haujlwm li cas?


Txhawm rau kev nkag siab yooj yim ntawm photocatalyst, koj yuav tsum nkag siab tias nws yog kev ua haujlwm uas tshwm sim thaum lub sij hawm ua kom lub ntsej muag tsoo lub nplaim ntu ntawm cov khoom siv hluav taws xob. Thiab cov photocatalyst pab ua rau kev rhuav tshem cov pa phem ib puag ncig. Los yog koj tuaj yeem hais tias kom tsis muaj huab cua ntawm huab cua yog ua tau nrog cov txheej txheem no.


photicatalyst kev txiav txim siab


Hauv cov txheej txheem no, cov catalyst tsis hloov nws tus kheej lossis nws kuj tsis noj rau hauv cov tshuaj lom neeg cov tshuaj tiv thaiv, yog li kev hloov kho ntawm ob txheej txheem tshwm sim.


Muaj ntau yam kev tshawb fawb ntawm nws, tab sis TiO2 tau pom tias yog kev pabcuam ntawm decomposing cyanide hauv dej thiab tam sim no nws tseem decomposing cov kab mob hauv huab cua kom tsis muaj menyuam.


Photocatalyst yog cov lus siv dav dav rau cov khoom siv duab-semiconductor nrog photocatalytic muaj nuj nqi sawv cev los ntawm nanometer TiO2 (titanium dioxide).


Kev pleev xim rau nws rau saum npoo ntawm cov substrate, hauv qab qhov kev ua ntawm lub teeb ci ultraviolet, tuaj yeem ua rau cov organic lossis inorganic tshuaj cuam tshuam los tiv thaiv oxidation-txo cov tshuaj tiv thaiv.


Tom qab ntawd nws tuaj yeem tua ntau hom kab mob, thiab tuaj yeem ua rau cov kab mob thiab cov tshuaj tua tsis tau zoo. Nws kuj tseem tuaj yeem rhuav tshem qee lub neej tsw phem los ntawm tib neeg kev ua ub no.


3.2 Why is TiO2 a photocatalyst for air sterilization?


Nws ntseeg tau tias cov khoom ploj ntawm TiO2 tau paub los ntawm ib nrab-caug xyoo. Qhov teeb meem tsuas yog tsim hauv cov ntawv thov uas zoo li daws tam sim no.


TiO2


Yog li, tam sim no titanium dioxide tuaj yeem siv rau cov cua kom tsis muaj pa los ntawm kev siv ntau yam thiab ib qho ntawm lawv yog UV teeb.


It can decompose any pollutants and we all can see the increasing health problems in the world. So, climate change is real and so is the TiO2 for air sterilization.


Ntau cov kev sim thiab kev tshawb fawb qhia pom qhov txiaj ntsig nyob rau hauv kev nyiam thiab yog vim li cas peb thiaj khov kho tsim ntau yam kev siv sab hauv thiab sab nraum zoov siv nws los ntxuav huab cua los ntawm cov kab mob.


3.3 Properties of TiO2


Here are the main properties of the TiO2 that you must know to understand the importance of it for UV technology used for air sterilization.

3.4 TiO2 can kill Virus and Bacteria


If you have concerns that the TiO2 can kill bacteria or not, you must know that it does not just kill the cells of bacteria but decompose them. So, not this is one of the most effective photocatalysts as compared to any other agent.


And if we compare it to the chlorine, the TiO2 is 3 times stronger than that in killing the bacteria. The use of it can reduce or eliminate the polluted compounds in the air such as NOx, cigarette smoke, as well as volatile compounds arising from various construction materials. So, it is eventually a solution for pollutant areas.


3.5 TiO2 is not harmful to humans


The other benefit of titanium dioxide is that it does not penetrate from healthy skin therefore, it cannot damage the human skin or cause any serious health problems like other UV lights.


3.6 UVled+Photocatalyst


In the whole sterilization, TiO2 has the bactericidal effect of photocatalyst under UVA irradiation. Not only can kill the virus, but also reduce the formaldehyde in the room.


uv air solution for mini splits


For viruses not killed by TiO2, UVC can play a supplementary role. Because UVC only provides auxiliary functions and does not require so much energy, it reduces a lot of costs and makes it acceptable to most companies and people.


The conclusion is that we need a safe and healthy environment to breathe. So, the TiO2 photocatalyst in UV LED lights can impact hugely on human health right now. The ongoing chaos of air pollution is also indicating the presence of many bacterial pollutants in the air and if UVled+ photocatalyst can help us in reducing it then, why not?
