Izinto zokwakha zemishini yezokwelapha zingahlukaniswa ngezigaba ezimbili: izinto zensimbi nezinto zokwakha ze-polymer. Izakhiwo zezinto zensimbi zizinzile futhi zinokubekezelela okuhle izindlela ezahlukene zokubulala inzalo. Ngakho-ke, ukubekezelela izinto zokwakha ze-polymer kuvame ukucatshangelwa ekukhetheni izindlela zokubulala inzalo. Izinto zokwakha ze-polymer zezokwelapha ezisetshenziswa kakhulu kumadivayisi ezokwelapha ikakhulukazi i-polyethylene, i-polyvinyl chloride, i-polypropylene, i-polyester, njll., zonke ezinokuzivumelanisa kahle nezinto zokwakha.i-ethylene oxide (EO)indlela yokubulala inzalo.

EOiyi-batten ene-spectrum sterilant engabulala amagciwane ahlukahlukene ezingeni lokushisa legumbi, okuhlanganisa ama-spores, amagciwane e-tuberculosis, amagciwane, amagciwane, isikhunta, njll. Ezingeni lokushisa legumbi kanye nengcindezi,EOiyigesi engenambala, inzima kunomoya, futhi inephunga elimnandi le-ether. Uma izinga lokushisa lingaphansi kuka-10.8℃, igesi iyancibilika bese iba uketshezi olucacile olungenambala emazingeni okushisa aphansi. Ingaxutshwa namanzi nganoma iyiphi indlela futhi ingancibilika ezinyibilikisini ezisetshenziswa kakhulu eziphilayo. Umfutho womusi we-EO mkhulu kakhulu, ngakho-ke inokungena okunamandla ezintweni ezihlanziwe, ingangena kuma-micropores futhi ifinyelele engxenyeni ejulile yezinto, okusiza ekuhlanzeni ngokuphelele.

Izinga Lokushisa Lokuhlanza Inzalo

Ku-i-ethylene oxidei-sterilizer, ukunyakaza kwama-molecule e-ethylene oxide kuyaqina njengoba izinga lokushisa likhuphuka, okusiza ekufinyeleleni izingxenye ezifanele futhi kuthuthukiswe umphumela wokubulala inzalo. Kodwa-ke, enkambisweni yokukhiqiza yangempela, izinga lokushisa lokubulala inzalo alikwazi ukukhushulwa unomphela. Ngaphezu kokucabangela izindleko zamandla, ukusebenza kwemishini, njll., umthelela wokushisa ekusebenzeni komkhiqizo kumele futhi ucatshangelwe. Amazinga okushisa aphezulu kakhulu angasheshisa ukubola kwezinto ze-polymer, okuholela emikhiqizweni engafaneleki noma impilo yenkonzo emfushane, njll.Ngakho-ke, izinga lokushisa lokubulala amagciwane le-ethylene oxide livame ukuba ngu-30-60℃.

Umswakama Olinganiselwe

Amanzi ayingxenye ye-i-ethylene oxideukusabela kokubulala amagciwane. Kungokuqinisekisa umswakama othile kuphela ku-sterilizer lapho i-ethylene oxide kanye nama-microorganisms kungabhekana nokusabela kwe-alkylation ukuze kufezwe injongo yokubulala amagciwane. Ngesikhathi esifanayo, ukuba khona kwamanzi kungasheshisa nokwenyuka kwezinga lokushisa ku-sterilizer futhi kukhuthaze ukusatshalaliswa okufanayo kwamandla okushisa.Umswakama olinganiselwe wei-ethylene oxideukubulala amagciwane kungu-40%-80%.Uma kungaphansi kuka-30%, kulula ukubangela ukwehluleka kokubulala inzalo.

Ukugxila

Ngemva kokunquma izinga lokushisa lokubulala amagciwane kanye nomswakama ohlobene,i-ethylene oxideukuhlushwa kanye nokusebenza kahle kokubulala inzalo ngokuvamile kubonisa ukusabela kwe-kinetic kwe-first-order, okungukuthi, izinga lokusabela liyakhula ngokwanda kokuhlushwa kwe-ethylene oxide ku-sterilizer. Kodwa-ke, ukukhula kwayo akunamkhawulo.Uma izinga lokushisa lidlula ama-37°C futhi ukuhlushwa kwe-ethylene oxide kungaphezu kwama-884 mg/L, kungena esimweni sokusabela kwe-zero-order., kanyei-ethylene oxideUkuhlushwa akunawo umthelela omkhulu esilinganisweni sokusabela.

Isikhathi Sesenzo

Uma kwenziwa ukuqinisekiswa kokubulala inzalo, indlela yomjikelezo wesigamu ivame ukusetshenziswa ukunquma isikhathi sokubulala inzalo. Indlela yomjikelezo wesigamu isho ukuthi uma ezinye izilinganiso ngaphandle kwesikhathi zingashintshi, isikhathi sesenzo sihlukaniswa phakathi ngokulandelana kuze kutholakale isikhathi esifushane kakhulu sokuthi izinto ezihlanziwe zifinyelele esimweni sokubulala inzalo. Ukuhlolwa kokubulala inzalo kuphinda izikhathi ezi-3. Uma umphumela wokubulala inzalo ungatholakala, unganqunywa njengesigamu somjikelezo. Ukuze kuqinisekiswe umphumela wokubulala inzalo,isikhathi sangempela sokubulala inzalo esinqunyiwe kufanele okungenani sibe kabili kunesigamu somjikelezo, kodwa isikhathi sesenzo kufanele sibalwe kusukela lapho izinga lokushisa, umswakama ohlobene,i-ethylene oxideukuhlushwa kanye nezinye izimo ku-sterilizer kuhlangabezana nezidingo zokubulala inzalo.

Izinto zokupakisha

Izindlela ezahlukene zokuhlanza zinezidingo ezahlukene zezinto zokupakisha. Ukuzivumelanisa nezimo kwezinto zokupakisha ezisetshenziswa enkambisweni yokuhlanza kufanele kucatshangelwe. Izinto zokupakisha ezinhle, ikakhulukazi izinto zokupakisha ezincane kakhulu, zihlobene ngqo nomphumela wokuhlanza we-ethylene oxide. Lapho ukhetha izinto zokupakisha, okungenani izici ezifana nokubekezelela ukuhlanza, ukungena komoya, kanye nezakhiwo zokulwa namagciwane kufanele kucatshangelwe.I-ethylene oxideUkuhlanza kudinga izinto zokupakisha ukuze kube nokungena komoya okuthile.
