UV Ultraviolet Sterilization Txoj Cai thiab Daim Ntawv Thov: UV sterilization muaj keeb kwm ntev.Xyoo 1903, tus kws tshawb fawb Danish Niels Finsen tau thov kev kho mob niaj hnub raws li lub hauv paus ntsiab lus ntawm lub teeb kom tsis muaj menyuam thiab tau txais txiaj ntsig Nobel nqi zog hauv Physiology lossis Tshuaj.Nyob rau hauv ib puas xyoo dhau los, UV sterilization tau ua lub luag haujlwm tseem ceeb hauv kev tiv thaiv thiab kho cov kab mob sib kis mob hnyav hauv tib neeg, xws li "ob kab" xwm txheej hauv North America xyoo 1990, SARS hauv Suav teb xyoo 2003, thiab MERS nyob rau hauv Middle East hauv 2012. Tsis ntev los no, vim muaj tus kabmob tshiab tshiab (2019-nCoV) tshwm sim hauv Suav teb, UV lub teeb tau lees paub tias nws muaj txiaj ntsig zoo hauv kev tua cov kabmob, dhau los ua ib qho tseem ceeb rau kev tswj kev kis tus kabmob sib kis thiab ua kom ntseeg tau. kev nyab xeeb lub neej.
UV Sterilization Txoj Cai: UV lub teeb muab faib ua A-band (315 txog 400 nm), B-band (280 txog 315 nm), C-band (200 txog 280 nm), thiab nqus UV (100-200 nm) raws li nws wavelength ntau yam.Feem ntau, C-band UV teeb yog siv los ua kom tsis muaj menyuam.Tom qab raug rau C-band UV teeb, cov nucleic acid (RNA thiab DNA) nyob rau hauv cov kab mob nqus lub zog ntawm UV photons, ua rau lub hauv paus khub rau polymerize thiab tiv thaiv cov protein synthesis, uas ua rau cov kab mob tsis tuaj yeem rov tsim dua, yog li ua tiav cov txheej txheem. lub hom phiaj ntawm sterilization.
Qhov zoo ntawm UV Sterilization:
1) UV sterilization ua rau tsis muaj cov khoom seem lossis cov khoom muaj kuab lom, tsis txhob muaj kuab paug rau ib puag ncig thiab oxidation lossis corrosion ntawm cov khoom raug sterilized.
2) UV sterilization khoom yog ib qho yooj yim rau nruab thiab tswj, muaj kev txhim khu kev qha, thiab tus nqi qis.Cov tshuaj sterilizers xws li tshuaj chlorine, chlorine dioxide, ozone, thiab peracetic acid yog cov tshuaj lom heev, flammable, explosive, los yog corrosive yam uas yuav tsum tau nruj thiab tshwj xeeb sterilization yuav tsum tau rau ntau lawm, tsheb thauj mus los, cia, thiab siv.
3) UV sterilization yog dav-spectrum thiab muaj txiaj ntsig zoo, tuaj yeem tua cov kab mob feem ntau nrog rau cov kab mob protozoa, kab mob, kab mob, thiab lwm yam. Cov kab hluav taws xob ntawm 40 mJ / cm2 (feem ntau tuaj yeem ua tiav thaum lub teeb qis mercury yog irradiated ntawm qhov deb ntawm ib meter rau ib feeb) tuaj yeem tua 99.99% ntawm cov kab mob pathogenic.
UV sterilization muaj qhov dav-spectrum thiab muaj txiaj ntsig zoo ntawm cov kab mob tua kab mob rau feem ntau cov kab mob pathogenic, suav nrog tus kabmob tshiab (2019-nCoV).Piv nrog rau cov tshuaj sterilizers ib txwm siv, UV sterilization muaj qhov zoo ntawm tsis muaj kev ua qias tuaj tom ntej, kev ua haujlwm ruaj khov, thiab kev ua haujlwm siab hauv kev tua kab mob, uas tuaj yeem muaj txiaj ntsig zoo hauv kev tswj cov kab mob sib kis.
