Qhov txawv ntawm Ultraviolet Disinfection Tube Thiab Led Ultraviolet Disinfection Teeb
Feb 03, 2022
Ua hauj lwm hauv paus ntsiab lus ntawm ultraviolet sterilization
UVC ultraviolet lub teeb nrog cov kab mob bactericidal (tsuas yog 240 nm 280 nm) yog siv los rhuav tshem cov qauv molecular ntawm DNA (deoxyribonucleic acid) thiab RNA (ribonucleic acid) ntawm cov kab mob microbial, uas ua rau kev tuag ntawm cov hlwb loj hlob thiab cov hlwb regenerative, thiaj li. ua tiav cov nyhuv ntawm sterilization thiab tshuaj tua kab mob.
Tam sim no, muaj ob lub teeb ci tseem ceeb ntawm kev tua kab mob ultraviolet thiab ua kom tsis muaj menyuam lub teeb - gas paug lub teeb qhov chaw thiab khoom siv - xeev lub teeb qhov chaw.
Gas paug lub teeb qhov chaw yog qhov tsawg tshaj plaws - siab mercury teeb. Nws txoj cai luminous yog tib yam li lub teeb fluorescent uas peb tau siv ua ntej. Nws excites cov mercury atoms nyob rau hauv lub teeb raj. Qhov qis-siab mercury vapor feem ntau ua rau 254 nm UVC ultraviolet (kua hluav taws xob ua haujlwm 30 feem pua 60 feem pua) thiab 185 nm UVD ultraviolet (kua hluav taws xob efficiency 5 feem pua 15%)
UVC ultraviolet sterilization muaj txiaj ntsig zoo, tab sis cov kab hluav taws xob ultraviolet tsuas tuaj yeem kis tau rau hauv txoj kab ncaj nraim thiab muaj kev nkag mus tsis muaj zog, yog li muaj qhov thaiv kab mob tua kab mob tuag. Txawm hais tias 185nm UVD ultraviolet lub teeb nws tus kheej tsis muaj lub cev muaj zog thiab ua haujlwm kom tsis muaj menyuam thiab tua kab mob, nws tuaj yeem decompose cov pa oxygen hauv huab cua thiab ua ke los tsim ozone. Ozone muaj cov nyhuv oxidation muaj zog thiab tuaj yeem ncav cuag txhua qhov chaw nrog cov cua ntws kom ua tiav kom tsis muaj menyuam thiab tua kab mob (biochemical oxidation sterilization).
Txawm li cas los xij, ozone concentration ntau dhau ua rau muaj kev phom sij rau tib neeg lub cev thiab tuaj yeem ua rau lub hauv siab nruj thiab kiv taub hau. Yog li ntawd, yog tias koj yuav lub teeb ultraviolet nrog ozone, koj yuav tsum qhib lub qhov rais rau qhov cua rau 30 60 feeb tom qab ua kom tsis muaj menyuam.
The advantages of low-pressure mercury lamp are mature technology and high sterilization efficiency, but its volume is large and there is a small amount of mercury pollution (usually is placed where children can't touch, it's not good to break it).
Qhov txawv ntawm ultraviolet teeb hlaws thiab quartz iav teeb raj
LED lub teeb hlaws: 1 Broad spectrum sterilization: nws muaj peev xwm tua tau cov kab mob propagules, spores, kab mob thiab fungi los ntawm kev rhuav tshem DNA thiab lwm yam khoom siv caj ces.
2. Purifiable organics: zoo tshem tawm formaldehyde, toluene thiab lwm yam organics nyob rau hauv cov huab cua, tshem tawm peculiar tsw thiab ua kom huab cua fresher.
3. Kev tiv thaiv ib puag ncig thiab kev txuag hluav taws xob: kev siv hluav taws xob ntawm ib qho uvc - coj tsuas yog 1W, tab sis kev ua kom tsis muaj menyuam yog siab li 99.99 feem pua
4. Tsis muaj tshuaj lom: uvc-led tsis tsim ozone teeb meem rau tib neeg lub cev thiab tuaj yeem siv rau hauv tib neeg qhov chaw ua haujlwm.
5. Kev pab lub neej: lub neej kev pab cuam ntawm uvc-led teeb yog ntau tshaj 20000 teev.
Quartz tube ultraviolet sterilization teeb:
1. Nws muaj cov tshuaj phem mercury, uas yuav tsim ozone thiab ua rau tib neeg lub cev raug mob.
2. Lub teeb pom kev loj loj, tsis sib haum luminous siv nyob txhua qhov chaw, thiab lub zog tsis ruaj khov tom qab pib ua haujlwm
3. Lub neej ua haujlwm nyob nruab nrab ntawm 800-3000 teev.
4. Cov txheej txheem tshwj xeeb thiab nyuaj ua. Nws muaj cov tshuaj lom thiab yuav ua rau cov pa phem thib ob rau qhov chaw ecological tom qab kev puas tsuaj.
