1. UV yog dab tsi?

Ua ntej, cia peb tshuaj xyuas lub tswvyim ntawm UV. UV, piv txwv li ultraviolet, piv txwv li ultraviolet, yog ib qho hluav taws xob hluav taws xob nrog lub wavelength ntawm 10 nm thiab 400 nm. UV nyob rau hauv ntau pawg tuaj yeem muab faib ua UVA, UVB thiab UVC.

UVA: nrog lub wavelength ntev li ntawm 320-400nm, nws tuaj yeem nkag mus rau huab thiab iav rau hauv chav tsev thiab lub tsheb, nkag mus rau hauv cov tawv nqaij ntawm daim tawv nqaij thiab ua rau tanning. UVA tuaj yeem faib ua uva-2 (320-340nm) thiab UVA-1 (340-400nm).

UVB: lub wavelength nyob nruab nrab, thiab lub wavelength yog nyob nruab nrab ntawm 280-320nm. Nws yuav raug nqus los ntawm txheej ozone, ua rau tshav kub kub, tawv nqaij liab, o, kub thiab mob, thiab blistering los yog tev nyob rau hauv mob hnyav.

UVC: lub wavelength nyob nruab nrab ntawm 100-280nm, tab sis lub wavelength hauv qab 200nm yog nqus ultraviolet, yog li nws tuaj yeem nqus tau los ntawm huab cua. Yog li ntawd, lub wavelength uas UVC tuaj yeem hla cov huab cua nyob nruab nrab ntawm 200-280nm. Qhov luv luv nws wavelength yog, qhov txaus ntshai nws yog. Txawm li cas los xij, nws tuaj yeem thaiv los ntawm txheej ozone, thiab tsuas yog ib qho me me xwb thiaj li ncav cuag lub ntiaj teb.

2. Lub hauv paus ntsiab lus ntawm UV sterilization?

UV tuaj yeem rhuav tshem DNA (deoxyribonucleic acid) lossis RNA (ribonucleic acid) cov qauv molecular ntawm cov kab mob, kom cov kab mob tuag lossis tsis tuaj yeem tsim tawm, thiaj li ua tiav lub hom phiaj ntawm kev ua kom tsis muaj menyuam.

3. UV sterilization band?

Raws li lub koom haum thoob ntiaj teb ultraviolet, "lub ultraviolet spectrum (lub cheeb tsam 'sterilization') uas yog ib qho tseem ceeb heev rau cov dej thiab cua tua kab mob yog ntau yam absorbed los ntawm DNA (RNA hauv qee cov kab mob). Qhov no sterilization band yog hais txog 200-300 nm ". Nws yog lub npe hu hais tias lub sterilization wavelength txuas mus rau ntau tshaj 280nm, thiab tam sim no nws yog feem ntau txiav txim siab mus cuag 300nm. Txawm li cas los xij, qhov no kuj tseem yuav hloov nrog kev tshawb fawb ntxiv. Cov kws tshawb fawb tau ua pov thawj tias lub teeb ultraviolet nrog wavelengths ntawm 280nm thiab 300nm tuaj yeem siv rau kev ua kom tsis muaj menyuam.

4. Dab tsi yog qhov zoo tshaj plaws wavelength rau sterilization?

Muaj kev to taub yuam kev tias 254 nm yog qhov zoo tshaj plaws wavelength rau kom tsis muaj menyuam, vim hais tias lub ncov wavelength ntawm lub teeb mercury uas tsis tshua muaj siab (tsuas yog txiav txim los ntawm lub physics ntawm lub teeb) yog 253.7 nm. Hauv cov ntsiab lus, raws li tau piav qhia saum toj no, qee qhov ntau ntawm wavelengths muaj cov kab mob bactericidal. Txawm li cas los xij, nws feem ntau suav hais tias lub wavelength ntawm 265nm yog qhov zoo tshaj plaws, vim tias qhov wavelength no yog lub ncov ntawm DNA absorption nkhaus. Yog li ntawd, UVC yog qhov tsim nyog tshaj plaws rau kev ua kom tsis muaj menyuam.

5. Vim li cas keeb kwm thiaj xaiv UVCLED?

Keeb kwm, mercury teeb yog tib txoj kev xaiv rau UV sterilization. Txawm li cas los, lub miniaturization ntawmUVC LEDCheebtsam coj ntau lub tswv yim rau hauv daim ntawv thov scene, ntau yam uas tsis tuaj yeem pom tau los ntawm cov teeb mercury ib txwm muaj. Tsis tas li ntawd, UVC coj kuj tseem muaj ntau yam zoo, xws li kev pib ceev ceev, ntau lub sijhawm hloov pauv, muaj roj teeb lub zog thiab lwm yam.

6. UVC LED daim ntawv thov scenario?

Kev ua kom tsis muaj menyuam: cov khoom siv hluav taws xob ntau zaus xws li cov khoom siv kho mob, cov khoom siv rau niam thiab menyuam mos, chav tso quav ntse, tub yees, lub txee rau khoom noj, lub thawv tshiab, cov thoob khib nyiab ntse, thermos khob, escalator handrail thiab daim pib vending tshuab khawm;

Tseem dej kom tsis muaj menyuam: lub tank dej ntawm lub tshuab xa dej, lub tshuab nqus dej thiab lub tshuab ua dej khov;

Flowing water sterilization: flowing water sterilization module, direct haus dej dispenser;

Cua sterilization: cua purifier, cua txias.

7. Yuav ua li cas xaiv UVC LED?

Nws tuaj yeem xaiv los ntawm qhov tsis xws li lub zog kho qhov muag, lub siab tshaj plaws wavelength, kev pabcuam lub neej, lub kaum sab xis tso tawm thiab lwm yam.

Lub hwj chim kho qhov muag: UVC LED optical fais fab muaj nyob rau hauv kev ua lag luam tam sim no muaj li ntawm 2MW, 10 MW txog 100 MW. Cov ntawv thov sib txawv muaj cov kev xav tau ntawm lub zog sib txawv. Feem ntau hais lus, lub hwj chim kho qhov muag tuaj yeem sib phim los ntawm kev sib txuas ntawm irradiation nrug, dynamic thov lossis qhov xav tau zoo li qub. Qhov loj dua qhov irradiation nrug, qhov xav tau ntau dua, thiab ntau dua qhov xav tau lub zog kho qhov muag.

Peak wavelength: raws li tau hais los saum no, 265nm yog qhov zoo tshaj plaws wavelength rau kom tsis muaj menyuam, tab sis xav tias muaj qhov sib txawv me ntsis ntawm tus nqi nruab nrab ntawm lub ncov wavelength ntawm cov tuam txhab, qhov tseeb, lub zog kho qhov muag yog qhov tseem ceeb tshaj plaws los ntsuas kev ua kom tsis muaj menyuam.

Kev pabcuam lub neej: xav txog qhov kev thov rau kev pabcuam lub neej raws li lub sijhawm ua haujlwm ntawm cov ntawv thov tshwj xeeb, thiab nrhiav qhov tsim nyog tshaj UVC coj, uas yog qhov zoo tshaj plaws.

Lub teeb tso zis lub kaum sab xis: lub teeb tso zis lub kaum sab xis ntawm lub teeb hlaws dai nrog lub dav hlau lens feem ntau yog nyob nruab nrab ntawm 120-140 °, thiab lub teeb tso zis lub kaum sab xis encapsulated nrog spherical lens yog adjustable ntawm 60-140 °. Qhov tseeb, tsis muaj teeb meem loj npaum li cas lub kaum sab xis ntawm UVC LED raug xaiv, LEDs txaus tuaj yeem tsim los npog tag nrho qhov chaw kom tsis muaj menyuam. Nyob rau hauv qhov xwm txheej tsis hnov ​​​​qab txog kev ua kom tsis muaj menyuam, lub kaum sab xis me me tuaj yeem ua rau lub teeb pom kev zoo, yog li lub sijhawm ua kom tsis muaj menyuam yog luv dua.
