Izinto zokwakha zemishini yezokwelapha zingahlukaniswa zibe izigaba ezimbili: izinto zensimbi nezinto ze-polymer. Izakhiwo zensimbi azinzile futhi zinokubekezelela okuhle ezindleleni ezihlukene zokuvala inzalo. Ngakho-ke, ukubekezelelana kwezinto ze-polymer kuvame ukucatshangelwa ekukhethweni kwezindlela zokuvala inzalo. Izinto ezisetshenziswa kakhulu ze-polymer yezokwelapha zemishini yezokwelapha ikakhulukazi i-polyethylene, i-polyvinyl chloride, i-polypropylene, i-polyester, njll., konke okuvumelana nezimo ezinhlei-ethylene oxide (EO)indlela yokuvala inzalo.

EOiyi-wide spectrum sterilant engabulala ama-microorganisms ahlukahlukene ekamelweni lokushisa, okuhlanganisa izinhlamvu, amagciwane esifo sofuba, amagciwane, amagciwane, isikhunta, njll. Ezingeni lokushisa nengcindezi,EOiyigesi engenambala, isinda kunomoya, futhi inephunga le-ether elimnandi. Lapho izinga lokushisa lingaphansi kuka-10.8℃, igesi iyancibilika futhi iba uketshezi olungenambala olubonisa ngale emazingeni okushisa aphansi. Ingaxutshwa namanzi kunoma iyiphi ingxenye futhi ingancibilika kuzincibilikisi zemvelo ezisetshenziswa kakhulu. Umfutho we-vapor we-EO mkhulu kakhulu, ngakho unokungena okuqinile ezintweni eziyinzalo, ungangena kuma-micropores futhi ufinyelele engxenyeni ejulile yezinto, okuvumela ukuvala inzalo ngokuphelele.

I-Sterilization Temperature

Kwei-ethylene oxidei-sterilizer, ukunyakaza kwama-molecule e-ethylene oxide kuya ngokushuba njengoba izinga lokushisa likhuphuka, okuvumela ukuthi lifinyelele ezingxenyeni ezihambisanayo kanye nokwenza ngcono umphumela wokuvala inzalo. Kodwa-ke, enqubweni yokukhiqiza yangempela, izinga lokushisa lokuvala inzalo alikwazi ukunyuswa unomphela. Ngokungeziwe ekucabangeleni izindleko zamandla, ukusebenza kwemishini, njll., umthelela wezinga lokushisa ekusebenzeni komkhiqizo nawo kufanele ucatshangelwe. Amazinga okushisa aphakeme ngokweqile angasheshisa ukubola kwezinto ze-polymer, okuholela emikhiqizweni engafanelekile noma impilo yesevisi efinyeziwe, njll.Ngakho-ke, izinga lokushisa ethylene oxide inzalo ngokuvamile 30-60 ℃.

Umswakama Ohlobene

Amanzi ungumhlanganyeli wei-ethylene oxideukusabela kokuvala inzalo. Kuphela ngokuqinisekisa umswakama othile ohlobene nesibulala-magciwane lapho i-ethylene oxide nama-microorganisms angathola ukusabela kwe-alkylation ukufeza inhloso yokuvala inzalo. Ngesikhathi esifanayo, ukuba khona kwamanzi kungasheshisa nokukhuphuka kwezinga lokushisa ku-sterilizer futhi kukhuthaze ukusatshalaliswa okufanayo kwamandla okushisa.Umswakama ohlobene wei-ethylene oxideukuvala inzalo kungama-40% -80%.Uma ingaphansi kuka-30%, kulula ukubangela ukwehluleka ukuvala inzalo.

Ukugxila

Ngemva kokunquma izinga lokushisa inzalo kanye nomswakama isihlobo, ii-ethylene oxideukugxilisa ingqondo nokusebenza kahle kokuvala inzalo ngokuvamile kukhombisa ukusabela kwe-kinetic ye-oda lokuqala, okungukuthi, izinga lokusabela liyakhuphuka ngokunyuka kokugxiliswa kwe-ethylene oxide kusibulali magciwane. Nokho, ukukhula kwayo akunamkhawulo.Uma izinga lokushisa lingaphezu kuka-37°C futhi ukugxiliswa kwe-ethylene oxide kungaphezu kuka-884 mg/L, ingena esimweni sokusabela kwe-oda elinguziro., kanyei-ethylene oxideukugxila kunomphumela omncane kwisilinganiso sokuphendula.

Isikhathi Sokwenza

Lapho kwenziwa ukuqinisekiswa kokuvala inzalo, indlela yomjikelezo oyingxenye ivame ukusetshenziswa ukunquma isikhathi sokuvala inzalo. Indlela yomjikelezo wohhafu isho ukuthi uma amanye amapharamitha ngaphandle kwesikhathi engashintshile, isikhathi sesenzo sincishiswa ngohhafu ngokulandelana kuze kube yilapho kutholakala isikhathi esifushane kakhulu sezinto ezibulala amagciwane ukuze zifinyelele esimweni esiyinyumba. Ukuhlolwa kokuvala inzalo kuyaphindwa izikhathi ezi-3. Uma umphumela wokuvala inzalo ungafinyelelwa, unganqunywa njengengxenye yomjikelezo. Ukuze uqinisekise umphumela wokuvala inzalo,isikhathi sangempela sokuvala inzalo esinqunyiwe kufanele sibe okungenani kabili uhhafu womjikelezo, kodwa isikhathi sesenzo kufanele sibalwe kusukela lapho izinga lokushisa, umswakama ohlobene,i-ethylene oxideukugxilisa ingqondo nezinye izimo kusibulala-magciwane kuhlangabezana nezidingo zokuvala inzalo.

Izinto zokupakisha

Izindlela ezihlukene zokuvala inzalo zinezidingo ezihlukene zezinto zokupakisha. Ukuvumelana nezimo kwezinto zokupakisha ezisetshenziselwa inqubo yokuvala inzalo kufanele kubhekwe. Izinto zokupakisha ezinhle, ikakhulukazi izinto zokupakisha ezincane kakhulu, zihlobene ngqo nomphumela wokuvala inzalo we-ethylene oxide. Lapho kukhethwa izinto zokupakisha, okungenani izici ezifana nokubekezelela inzalo, ukungena komoya, kanye nezakhiwo zokulwa namagciwane kufanele kucatshangelwe.I-Ethylene oxideukuvala inzalo kudinga izinto zokupakisha ukuze kube nokungena komoya okuthile.
