UV Ultraviolet Sterilization Nheyo uye Chishandiso: UV sterilization ine nhoroondo refu.Muna 1903, musayendisiti weDanish Niels Finsen akakurudzira fototherapy yemazuva ano zvichibva pamusimboti wekuvharisa chiedza uye akapihwa Mubairo weNobel muPhysiology kana Mushonga.Muzana ramakore rapfuura, kuvharirwa kweUV kwakaita basa rakakosha mukudzivirira uye kurapwa kwezvirwere zvinotapukira muvanhu, se "zvipembenene zviviri" chiitiko muNorth America muma1990s, SARS kuChina muna 2003, uye MERS munharaunda. Middle East muna 2012. Munguva ichangopfuura, nekuda kwekubuda kwakanyanya kweiyo coronavirus itsva (2019-nCoV) muChina, mwenje weUV wakazivikanwa nekuda kwehunyanzvi hwayo hwekuuraya hutachiona, ichiva nzira yakakosha yekudzora kupararira kwedenda uye kuve nechokwadi. kuchengeteka kwehupenyu.
UV Sterilization Musimboti: UV mwenje wakakamurwa kuita A-bhendi (315 kusvika 400 nm), B-bhendi (280 kusvika 315 nm), C-bhendi (200 kusvika 280 nm), uye vacuum UV (100-200 nm) zvinoenderana. kureba kwayo kwewavelength.Kazhinji, C-bhendi UV mwenje inoshandiswa pakuita sterilization.Mushure mekufumurwa kune C-band UV mwenje, iyo nucleic acid (RNA neDNA) mumamicroorganisms inotora simba reUV mafotoni, zvichiita kuti mabhesi maviri aite polymeri uye kudzivirira mapuroteni synthesis, izvo zvinoita kuti hutachiona hutadze kubereka, nekudaro kuwana chinangwa che sterilization.
Zvakanakira zveUV Sterilization:
1) UV sterilization haiburitse zvisaririra kana muchetura kubva-zvigadzirwa, kudzivirira kusvibiswa kwechipiri kune zvakatipoteredza uye oxidation kana ngura yezvinhu zviri sterilized.
2) UV sterilization midziyo iri nyore kuisa nekuchengetedza, ine kushanda kwakavimbika, uye ine mutengo wakaderera.Chinyakare chemakemikari sterilizers akadai seklorini, chlorine dioxide, ozone, uye peracetic asidhi ine muchetura, inogona kupisa, inoputika, kana inoparadza zvinhu zvinoda zvakaomarara uye zvakakosha sterilization zvinodiwa pakugadzira, kufambisa, kuchengetedza, uye kushandisa.
3) UV sterilization ine wide-spectrum uye inoshanda zvakanyanya, inokwanisa kuuraya akawanda pathogenic organisms zvinosanganisira protozoa, mabhakitiriya, mavhairasi, etc. The radiation dose of 40 mJ/cm2 (kazhinji inogoneka kana low-pressure mercury marambi ari irradiation ari chinhambwe. mita imwe kweminiti imwe) inogona kuuraya 99.99% yehutachiona hwehutachiona.
UV sterilization ine yakafara-spectrum uye inoshanda zvakanyanya bactericidal mhedzisiro pane akawanda pathogenic microorganisms, kusanganisira iyo itsva coronavirus (2019-nCoV).Zvichienzaniswa nezvinouraya makemikari echinyakare, UV sterilization ine zvakanakira kusasvibiswa kwechipiri, kushanda kwakavimbika, uye kugona kwakanyanya mukuuraya tupukanana, izvo zvinogona kukosha zvakanyanya mukudzora denda.
