Ethylene oxide (eo) yave ichishandiswa mukusawirwa uye kusungwa kwenguva yakareba uye ndiyo chete yemakemikari gasi sterlant inozivikanwa nenyika seyakavimbika kwazvo. Munguva yakapfuura,ethylene oxideyainyanyo kushandiswa kune yekufemerwa-kwechiyero chekutadza uye kusvibiswa. Nekuvandudzwa kwehunyanzvi hwazvino maindasitiri uye technology, ethterylexent oxide tekinoroji inogona kushandiswa zvakachengeteka mumasangano ekurapa kuti asimbe zvishandiso zvekurapa zvinotya kupisa nekunyorova.

Hunhu hwe ethylene oxide

Ethylene oxideChizvarwa chechipiri chemakemikari disinfeles mushure me formaldehyde. Iyo ichiri imwe yeanonyanya kutonhora disinfect uye inonyanya kukosha nhengo yeiyo ina ina yakadzika-tembiricha matongero ekudziya.

Ethylene oxide inyoka yakapusa yeiyo compound. Iyo isina ruvara gasi pamhepo tembiricha uye kumanikidzwa. Iyo inorema kupfuura mhepo uye ine inonhuhwirira otter inonhuwira. Etleyone oxide inopisa uye inoputika. Kana mhepo ine 3% kusvika 80%ethylene oxide. Iyo inowanzoshandiswa ethylexo oxide yekusagadzikana uye masimba ndeye 400 kusvika 800 mg / l, iyo iri mune inopisa uye inoputika kusungwa mumhepo, saka inofanira kushandiswa nekuchenjerera.

Ethylene oxide inogona kusanganiswa neinert magasi akadai secarbon dioxideMune chiyero che1: 9 kugadzira kuputika-chiratidzo chiratidzo, icho chakachengeteka chekusafinha uye kusagadzikana.Ethylene oxideinogona polymerize, asi kazhinji iyo polymerization inononoka uye inonyanya kuitika mumvura yemvura. Mumisipoti yeEtrayle oxide neCarbon dioxide kana yakacheneswa hydrocarbons, polmerization inoitika zvishoma nezvishoma uye yakasimba polymers isingasviki kuputika.

Nheyo ye ethylene oxide sterilization

1. Alkylation

Maitiro ekuita kweethylene oxideMukuuraya misoro dzakasiyana-siyana ndedzekunyora zvakanyanya. Nzvimbo dzechiito dzakasarudzika sulfhydryl (-sh), amino (-nh2), hydroxyl (-coh) uye hydroxyl (-oh) muProtein uye nucleic acid mamorekuru. Etleene oxide inogona kukonzera kuti mapoka agone kuita kuti ashanduke zvehupfumi, kuita izvi macromoleculuckols emazvo zvehutachiona zvisingaite, nekudaro kuuraya hutachiona.

2. Inhibit chiitiko cheBiological enzymes

Etleene oxide inogona kudzivirira chiitiko chemhando dzakasiyana-siyana dzehutachiona, dzakadai saPhosphane dehydrogease, cholisestererase uye imwe oxidases yemazvo metrosorms uye inotungamira kurufu rwavo.

3. Kuuraya zvinokanganisa pane microorganisms

Zvose zviri zviviriethylene oxidemvura uye gasi ine yakasimba microbicidal mhedzisiro. Mukuenzanisa, iyo microbicidal mhedzisiro yegesi inosimba, uye gasi rayo rinowanzoshandiswa mukusawarira uye kusimba.

Etleene oxide inonakidza kwazvo-spectrum yakakwenenzverwa iyo ine simba rakasimba uye isingawanzoitwa pamiviri yehutachiona yekuparadzira, hutachiona hwehutachiona, fungus, uye hutachiona. Kana ethyley oxide ichisangana nehutachiona, asi hutachiona hune mvura yakakwana, maitiro pakati petheryne oxide uye microorganisms chiitiko chekutanga chekutanga. Iyo dosi iyo inactivates yakachena tsika microorganisms, iyo curve yemhedzisiro mutsara wakananga pane imwe hafu-logarithmic kukosha.

Kushandisa mhando ye ethylene oxide sterilization

Ethylene oxidehaina kukuvadza zvinhu zvakasikwa uye zvine mupfuru yakasimba. Zvizhinji zvinhu zvisina kukodzera kuti zviitwe nenzira dzakawanda dzinogona kuraswa uye dzinoshatiswa ne ethylyone oxide. Inogona kushandiswa kusungwa kwezvigadzirwa zvesimbi, endoscopes, dialayzers uye kusafembera zvekurapa, zvakadai zvemapurasitiki emichero denderedzwa nzvimbo (sechipfeko chemakemikari, ganda, zvinyorwa, zvinyorwa, uye zvemafuta pendi).

Etleyle oxide haina kukuvadza zvinhu zvisina kufanira uye zvine mupfuru yakasimba. Zvizhinji zvinhu zvisina kukodzera kuti zviitwe nenzira dzakawanda dzinogona kuraswa uye dzinoshatiswa ne ethylyone oxide. Inogona kushandiswa kusungwa kwezvigadzirwa zvesimbi, endoscopes, dialayzers uye kusafembera zvekurapa, zvakadai zvemapurasitiki emichero denderedzwa nzvimbo (sechipfeko chemakemikari, ganda, zvinyorwa, zvinyorwa, uye zvemafuta pendi).

Zvinhu zvinokanganisa maitiro ekushushikanaethylene oxide

Iyo inosimbisa mhedzisiro ye ethylene oxide inokanganiswa nezvakawanda zvinhu. Kuti uzadzise zvakanakisa mashandiro ezvekushandiswa zvakasiyana-siyana, chete kudzora zvinhu zvakasiyana-siyana zvinogona kubatsira chaizvo kuita basa rayo mukuuraya hutachiona uye kuzadzisa chinangwa chayo chekutadza uye kusimba. Zvinhu zvikuru zvinokanganisa maitiro ekusimbisa ndeaya: kusunganidzwa, tembiricha, hunyoro, chiitiko, nguva, nezvimwe.
