254nm UVC LED teebyog lub teeb ci semiconductor uas siv ultraviolet C band (UVC, wavelength 200-280nm) rau kev ua kom tsis muaj menyuam thiab tua kab mob. Nws lub luag haujlwm tseem ceeb yog txhawm rau rhuav tshem DNA / RNA tus qauv ntawm cov kab mob thiab ua rau lawv poob lawv lub peev xwm ua me nyuam kom ua tiav kom tsis muaj menyuam. Cov hauv qab no yog nws cov kev siv tshwj xeeb thiab cov yam ntxwv:
Lub luag haujlwm tseem ceeb
High -kev ua kom tsis muaj menyuam thiab tshuaj tua kab mob
Lub hauv paus ntsiab lus: 254nm ultraviolet rays tuaj yeem ncaj qha rhuav tshem lub hauv paus khub hauv DNA / RNA ntawm cov kab mob, ua rau lawv tsis tuaj yeem rov ua dua lossis muaj sia nyob.
Sterilization ntau yam: Nws muaj qhov cuam tshuam tsis zoo rau cov kab mob (xws li Escherichia coli, Staphylococcus aureus), kab mob (xws li qee tus kab mob coronaviruses, kab mob khaub thuas), pwm, spores, thiab lwm yam.
Tsis muaj chemical residue: lub cev ua kom tsis muaj menyuam kom tsis txhob muaj cov tshuaj tua kab mob thib ob.
Daim ntawv thov scenarios
Kev kho mob thaj chaw: chav ua haujlwm, ntsuas qhov chaw, cua tua kab mob (yuav tsum tau koom tes nrog kaw kaw).
Kev kho dej: ntxuav cov dej haus thiab dej khib nyiab (xws li UVC LED rau kev khiav dej kom tsis muaj menyuam).
Cov khoom siv hauv tsev: cov khoom siv kom tsis muaj menyuam (qhov ncauj qhov ntswg, xov tooj ntawm tes, txhuam hniav thiab lwm yam khoom me me).
Khoom noj khoom haus kev lag luam: sterilization ntawm ntim nto thiab ntau lawm khoom.
Cua purification: ua ke nrog cov cua tshuab kom txo tau cov kab mob hauv huab cua.
Qhov zoo (piv rau cov teeb pom kev zoo mercury)
Kev tiv thaiv ib puag ncig: mercury-dawb, raws li cov cai ntawm Minamata Convention.
Instant pib thiab nres: tsis muaj preheating yuav tsum tau, fais fab thiab npaj siv.
Compact thiab portable: tuaj yeem muab tso rau hauv cov khoom siv tuav los yog qhov chaw me me.
Qhov tseeb wavelength: LED wavelength yog concentrated thiab ntau npaum.
Cov kev ceev faj
Kev nyab xeeb kev nyab xeeb: 254nm UVC yog teeb meem rau tib neeg lub cev, kev raug ncaj qha tuaj yeem ua rau daim tawv nqaij thiab ob lub qhov muag puas tsuaj, thiab yuav tsum tau siv rau hauv qhov chaw tsis muaj neeg siv los yog nruab nrog kev tiv thaiv tsim (xws li lub thawv kaw, tsis siv neeg kaw ua haujlwm).
Lifespan thiab efficiency: UVC LED lifespan yog li ntawm 5000-10000 teev, tab sis tej zaum yuav lwj nrog lub sij hawm siv nce.
Kev txwv cov tshuaj tua kab mob saum npoo: ncaj qha irradiation thiab tsis muaj kev cuam tshuam, ntxhib lossis ntxeem tau qhov chaw yuav cuam tshuam rau cov nyhuv.
Piv nrog rau lwm qhov chaw teeb pom kev UVC
Tsawg- siab mercury teeb (ib txwm 254nm lub teeb ci): kev ua haujlwm siab tab sis muaj mercury, maj mam hloov los ntawm LED.
Sib sib zog nqus ultraviolet UVC LED (xws li 265-280nm): qee cov LEDs tshiab muaj qhov ntev wavelengths, ntsuas kev ua kom tsis muaj menyuam thiab cov khoom siv lub neej.
254nm UVC LED teebyog ib qho ntawm cov cuab yeej tseem ceeb ntawm cov cuab yeej siv tshuaj tua kab mob niaj hnub no, tshwj xeeb tshaj yog tsim rau me me - nplai, txav tau yooj yim lossis ib puag ncig tus phooj ywg, tab sis cov cai tswj kev nyab xeeb yuav tsum ua raws li nruj me ntsis.
