Puas yog UV teeb yuav tsum tau hloov tom qab 1000 teev ntawm kev siv?
Sep 15, 2021
Ultraviolet teeb lub raj yog ib yam ntawm cov cuab yeej ua kom huv huv huab cua uas tau siv dav hauv cov tsev kho mob tam sim no. Qhov nruab nrab wavelength ntawm ultraviolet lub teeb siv rau kev tua kab mob hauv tsev kho mob yog 253.7nm. Ib qho kev siv irradiation yog ib qho tseem ceeb lav kom ntseeg tau tias cov nyhuv sterilization ntawm ultraviolet rays. Cov txheej txheem ib txwm yog los hloov nws tom qab 1000 teev ntawm kev siv. Qhov no puas tsim nyog?
Kev hloov ntawm lub teeb UV tsis yog nyob ntawm lub sijhawm sib xyaw ua ke. Thaum cov hluav taws xob siv hluav taws xob poob qis dua qhov xav tau (70μW / cm2), nws yuav tsum tau hloov lub sijhawm!
kuv lub teb chaws tau teev qhov nruab nrab lub neej ntawm cov teeb ci ultraviolet, uas yuav tsum tsis pub tsawg tshaj 5000 teev. Lub"Technical Specification for Disinfection in Medical Institutions" xav kom cov chaw tsim khoom UV teeb yuav tsum muab lub neej ua haujlwm tiag tiag. Kev pabcuam lub neej ntawm UV teeb nrog lub zog ≥ 30W, lub sijhawm los ntawm kev siv lub teeb tshiab rau 70μW / cm2, lossis lub sijhawm txo qis rau 70% ntawm qhov tseem ceeb ntawm lub teeb tshiab, yuav tsum tsis pub tsawg dua 1000 teev. . Hauv lwm lo lus, 1000 teev yog qhov tsawg kawg nkaus kev pabcuam lub neej ntawm UV teeb, tsis yog qhov hloov pauv.
Hauv kev ua haujlwm kho mob, nws feem ntau pom tias lub sijhawm siv ntawm lub teeb ci ultraviolet mus txog 1000 teev, txawm tias qhov siv hluav taws xob ntau tshaj 70μW / cm2, nws tseem hloov tau, uas yog qhov tsis xav tau thiab ua rau khib nyiab. Kuj tseem muaj qhov xwm txheej uas lub sijhawm siv ntawm lub teeb ci ultraviolet mus txog 1000 teev, thiab qhov kev siv hluav taws xob yog siab dua 70μW / cm2, lub teeb raj tsis hloov, tab sis cov ntaub ntawv siv sijhawm pib ntawm 0, uas yog qhov tsis xav tau.
