Guangmai Technology yog cov kws tshaj lij hauv kev ua 265nm UVC LED 6565 6868 4W 8W rau sterilizer.
Cov lus nug txog GMKJ UVC smd leds:
Puas tuaj yeem sib sib zog nqus ultraviolet rays decompose formaldehyde?
Muaj ob txoj kev kinetic nyob rau hauv decomposition ntawm formaldehyde los ntawm ultraviolet rays: ib tug yog hais tias photolysis yog ncaj qha cuam tshuam los ntawm ultraviolet rays; Lwm qhov yog tias cov hluav taws xob ultraviolet cuam tshuam nrog dej hauv huab cua los tsim OH radicals thiab decompose formaldehyde. (Mercury tubes zoo). Sib sib zog nqus ultraviolet rays tuaj yeem ncaj qha decompose organic pollutants xws li formaldehyde los ntawm kev rhuav tshem cov tshuaj lom neeg ntawm formaldehyde.
Puas tuaj yeem sib sib zog nqus ultraviolet decompose organic pollutants xws li formaldehyde? Qhov tseeb, ntau tus neeg xav tias nws yuav tsum tsis ua haujlwm, tab sis qhov tseeb nws tuaj yeem ua tau. Lub zog ntawm daim ntawv cog lus ntawm O - O daim ntawv cog lus yog 5.1eV sib raug rau 243nm, tab sis qhov tsim nyog C - H daim ntawv cog lus lub zog hauv cov khoom organic yog 4.31eV, sib raug rau 283nm, thiab C - O yog 3.39eV corres. Ultraviolet photon zog tuaj yeem siab dua li daim ntawv cog lus lub zog los rhuav tshem nws, ib yam li nws rhuav tshem DNA molecular saw, yog li lub teeb ultraviolet tuaj yeem decompose formaldehyde.
Tab sis peb kuj yuav tsum nco ntsoov tias cov txheej txheem decomposition ntawm formaldehyde yog qhov nyuaj heev, thiab nws ob txoj kev decomposition tseem cuam tshuam ncaj qha rau lub wavelength. Kev hloov pauv hauv quantum tawm los ntawm cov txheej txheem decomposition ntawm formaldehyde ntawm qhov sib txawv wavelengths. Txawm hais tias kuv tsis' tsis nkag siab tias ob lub ncov yog dab tsi ntawm 305nm thiab 340nm, tsis muaj qhov tsis ntseeg tias cov kab hluav taws xob ultraviolet tuaj yeem decompose formaldehyde ntawm lawv tus kheej. Nws tuaj yeem decomposed los ntawm kev sib piv rau toluene, TVOC, thiab ultraviolet lub teeb.
Ntev npaum li cas qhov kev sib kis ntawm qhov sib sib zog nqus ultraviolet UVC - LED hauv dej?
Ob qho dej ntshiab thiab dej kais dej qhia cov yam ntxwv zoo sib kis rau lub teeb nrog wavelengths ntawm 250 thiab 800 nm. Lub transmittance ntawm 5 hli thickness yog siab tshaj 80%. Thaum lub wavelength luv dua 250 nm, lub teeb haum ntawm ob qho tib si nce sai. Tshwj xeeb, kais dej absorbs lub teeb< 250="" nm="" ntau="" zog.="" 2.4cm="" attenuation="" rau="" 70="" %;="" 8.5cm="" attenuation="" rau="" 30%;="" 16.3cm="" attenuation="" rau="">
Raws li lub ntsiab lus ntawm qhov kev ncua deb, qhov nkag mus deb ntawm UVC ultraviolet rays hauv dej nyob deb npaum li cas? Txhua yam yog rov qab mus rau lub tswvyim ntawm daim ntawv cog lus lub zog. Nyob rau hauv cov dej molecules, daim ntawv cog lus zog ntawm H - O daim ntawv cog lus yog 485kJ / mol, uas sib raug rau 4.98eV, uas yog hais txog 249nm. Yog li ntawd, thaum kuaj qhov kis tau tus mob spectrum ntawm cov dej ntshiab, ntsuas ntsuas ntug pib poob ntawm txog 249nm. Raws li cov ntaub ntawv no, nws tuaj yeem hais tau tias cov kais dej ib txwm muaj qee qhov impurities hauv cov dej haus tsis muaj zog nqus ntawm 275 nm UVC - LED. Ultraviolet sterilization ntaus ntawv raws li lub hauv paus ntsiab lus ntawm UVC sterilization tuaj yeem tua tau ntev.
Qhov kev txiav txim siab tseem ceeb tshaj plaws yog tias nws yuav tsum yog qhov sib txawv ntawm lub teeb nrawm hauv cov txheej txheem nthuav tawm, ua rau muaj kev poob qis hauv qhov deb ntawm - qhov kawg siv. Qhov tseeb, hemispherical me me - lub kaum ntse ntse ntim yog ntau heev hauv kev lag luam UVA. Tib yam siv rau UVC ntim. Lub teeb me me - lub kaum ntse ntse tuaj yeem ua rau UVC kis tau mus deb. Nws yog qhov tsim nyog rau cov chaw tsim khoom xws li khob dej, lub tank dej ntev, thiab cov khoom siv dej kom tsis muaj menyuam.
High ambient humidity tsis ua rau muaj kev nqus ntawm UVC, uas txhais tau hais tias txawm nyob rau hauv chav sauna, UVC ultraviolet rays yuav siv tau tiag tiag - lub sij hawm sterilization.
