UV germicidal teeb xav tau kev saib xyuas
Txhua tus neeg tsis paub txog cov teeb pom kev zoo ntawm ultraviolet germicidal teeb, thiab ultraviolet sterilization tuaj yeem ua rau peb muaj kev ua kom tsis muaj menyuam thiab tua kab mob. Nws lub ntsiab ua haujlwm tseem ceeb yog nkag mus rau hauv cov cell membrane ntawm cov kab mob los ntawm ultraviolet hluav taws xob, rhuav tshem DNA qauv ntawm ntau yam kab mob, kab mob, kab mob thiab lwm yam kab mob hauv lub cev, rhuav tshem lawv cov nucleic acid molecular bonds, thiab ua rau cov kab mob tam sim ntawd tuag los yog tsis tuaj yeem tsim dua tshiab. . Ua kom puas thiab hloov DNA (deoxyribonucleic acid) qauv ntawm cov kab mob, thiaj li ua tiav cov txiaj ntsig ntawm kev ua kom tsis muaj menyuam thiab tua kab mob.
Peb nkag siab txog cov txiaj ntsig ntawm UV germicidal teeb, thiab tib lub sijhawm, peb kuj paub dab tsi yuav tsum tau them nyiaj rau hauv kuv UV germicidal teeb:
1. Tsis txhob cia lub teeb ci ultraviolet irradiate rau tib neeg, thiaj li tsis ua rau kev puas tsuaj. Cov teebmeem ntawm UV rays ntawm tib neeg daim tawv nqaij thiab ob lub qhov muag tau hais tshwj xeeb. luv-lub sij hawm raug rau tib neeg lub cev yuav ua rau daim tawv nqaij liab, khaus, thiab tsis haum papules; Kev raug mob ntev yuav ua rau muaj kev puas tsuaj loj rau ntawm daim tawv nqaij, thiab kev siv tshuaj txaus tuaj yeem ua rau mob qog noj ntshav. Ultraviolet rays kuj muaj teeb meem rau tib neeg lub qhov muag. Ntev - lub sij hawm raug ultraviolet hluav taws xob tuaj yeem ua rau cataracts thiab txawm qhov muag tsis pom.
2. When using ultraviolet rays to sterilize the surface of the article, the irradiated surface should be directly irradiated by ultraviolet rays, and a sufficient irradiation dose should be achieved. Due to the straight-line propagation of light, reflection, penetration or absorption occurs when it is blocked by an object. Ultraviolet disinfection requires that the wattage of ultraviolet lamps per cubic meter of space is Greater than or equal to 1.5W, and the irradiation time is generally 30 to 60 minutes. And it is stipulated that the irradiation intensity of ultraviolet rays shall not be lower than 70ūW/cm2, otherwise the sterilization effect will be poor or invalid, and the purpose of disinfection will not be achieved.
Thib peb, daim ntawv thov yuav tsum tau them sai sai rau kev so thiab ntxuav lub teeb. Thaum siv lub teeb tshiab, koj tuaj yeem siv 75 feem pua ntawm cov cawv cawv los so lub teeb lub raj kom tshem tawm cov plua plav thiab cov roj stains ntawm lub teeb raj. Nyob rau hauv tus txheej txheem ntawm kev siv, so tsis tu ncua thiab ua ib txoj hauj lwm zoo ntawm kev tu lub teeb raj, thiaj li tsis mus cuam tshuam lub violet transmittance thiab hluav taws xob siv.
