O le Ethylene oxide (EO) ua leva ona fa'aaogaina i le fa'amama ma fa'amama mo se taimi umi ma e na'o le pau lea o le kesi fa'ama'i fa'ama'i ua iloa e le lalolagi e sili ona fa'atuatuaina. I aso ua mavae,ethylene oxidesa masani ona fa'aaogaina mo fa'ama'i fa'ama'i ma fa'ama'i. Faatasi ai ma le atinaʻeina o tekinolosi faʻaonaponei faʻaonaponei ma masini ma tekonolosi atamai, ethylene oxide sterilization tekinolosi e mafai ona faʻaogaina saogalemu i falemaʻi e faʻamaʻi saʻo masini faʻafomaʻi e fefefe i le vevela ma le susu.

Uiga o le ethylene oxide

Ethylene oxideo le tupulaga lona lua lea o vailaau fa'ama'i ina ua uma formaldehyde. O lo'o avea pea ma se tasi o vaila'au malulu sili ona lelei ma o le sui pito sili ona taua o le fa'atekonolosi fa'amama fa'amama maualalo le vevela.

O le Ethylene oxide o se fa'apipi'i epoxy faigofie. O se kasa e le lanu i le vevela o le potu ma le mamafa. E sili atu le mamafa nai lo le ea ma e iai lona manogi manogi ether. O le Ethylene oxide e mu ma pa. Pe a iai le ea 3% i le 80%ethylene oxide, o se kasa fefiloi pa'u e fai, e mu pe pa pe a fa'aalia i le afi mumu. O le faʻaogaina masani o le ethylene oxide mo le faʻamaʻiina ma le faʻamaʻaina o le 400 i le 800 mg / L, lea o loʻo i totonu o le afi mumu ma le paʻu i luga o le ea, o lea e tatau ai ona faʻaogaina ma le faʻaeteete.

O le ethylene oxide e mafai ona fa'afefiloi ma kasa inert pei olecarbon dioxidei se fua faatatau o le 1:9 e fausia ai se paluga-faʻamaonia paluga, lea e sili atu le saogalemu mo faʻamaʻi ma sterilization.Ethylene oxidee mafai ona polymerize, ae masani le polymerization e telegese ma e masani ona tupu i le tulaga vai. I fa'afefiloi ole ethylene oxide ma le carbon dioxide po'o le fluorinated hydrocarbons, e fa'agesegese ona tupu le polymerization ma fa'aitiitia ai le pa.

Fa'avae ole Ethylene Oxide Sterilization

1. Alkylation

Le faiga o gaioiga aethylene oxidei le fasiotia o microorganisms eseese e tele lava alkylation. O nofoaga o gaioiga o sulfhydryl (-SH), amino (-NH2), hydroxyl (-COOH) ma le hydroxyl (-OH) i le porotini ma le nucleic acid molecules. O le Ethylene oxide e mafai ona fa'atupuina ai nei vaega e fa'agasolo ai le alkylation reactions, ma fa'aletonu ai nei meaola ninii o meaola ninii, ma fa'aumatia ai meaola ninii.

2. Taofi le gaioiga o enzymes olaola

Ethylene oxide e mafai ona faʻalavelaveina le gaioiga o enzymes eseese o microorganisms, e pei o le phosphate dehydrogenase, cholinesterase ma isi oxidases, faʻalavelaveina le faʻamaeʻaina o gaioiga masani o microorganisms ma oʻo atu ai i lo latou oti.

3. Aafiaga faʻaumatia i luga o meaola ninii

E luaethylene oxideo le vai ma le kesi e iai ni a'afiaga malosi o le microbicidal. I le faʻatusatusaina, o le microbicidal aʻafiaga o le kesi e malosi atu, ma o lona kesi e masani ona faʻaaogaina i le faʻamaʻiina ma le faʻamaʻaina.

O le Ethylene oxide o se fa'ama'i fa'ama'i fa'ama'i tele alaleo ma e malosi lona a'afiaga i tino fa'aola siama, spores siama, sigi, ma fa'ama'i. A fa'afeso'ota'i le ethylene oxide ma meaola ninii, ae o lo'o i ai i totonu o meaola ninii ia lava le vai, o le tali i le va o le ethylene oxide ma meaola ninii o se fa'asologa masani muamua. O le fua e fa'agata ai meaola ninii fa'aleaganu'u mama, o le fa'asologa o le tali o se laina sa'o i luga o le tau semi-logarithmic.

Fa'aaogāga ole ethylene oxide sterilization

Ethylene oxidee le fa'aleagaina aitema fa'ama'i ma e malosi lona ulu. O le tele o mea e le talafeagai mo le faʻamaʻiina e ala i auala lautele e mafai ona faʻamaʻi ma faʻamaʻi ile ethylene oxide. E mafai ona faʻaaogaina mo le sterilization o oloa uʻamea, endoscopes, dialyzers ma tuʻuina atu masini faafomaʻi, disinfection alamanuia ma sterilization o ie eseese, oloa palasitika, ma le disinfection o mea i nofoaga faʻamaʻi faʻamaʻi faʻamaʻi (e pei o ie alava vailaʻau, paʻu, pepa, pepa, ma vali suauu).

O le Ethylene oxide e le fa'aleagaina ai mea fa'amama ma e malosi lona ulu. O le tele o mea e le talafeagai mo le faʻamaʻiina e ala i auala lautele e mafai ona faʻamaʻi ma faʻamaʻi ile ethylene oxide. E mafai ona faʻaaogaina mo le sterilization o oloa uʻamea, endoscopes, dialyzers ma tuʻuina atu masini faafomaʻi, disinfection alamanuia ma sterilization o ie eseese, oloa palasitika, ma le disinfection o mea i nofoaga faʻamaʻi faʻamaʻi faʻamaʻi (e pei o ie alava vailaʻau, paʻu, pepa, pepa, ma vali suauu).

O a'afiaga e a'afia ai a'afiaga o le sterilization oethylene oxide

O le faʻamaʻiina o le ethylene oxide e aʻafia i le tele o mea. Ina ia mafai ona ausia le sili ona lelei sterilization aafiaga, naʻo le pulea lelei o itu eseese e mafai ona sili ona faatino lana matafaioi i le fasiotia o microorganisms ma ausia lona faamoemoega o le disinfection ma sterilization. O mea autu e aʻafia ai le faʻamaʻiina o aʻafiaga o: faʻatonuga, vevela, susū faʻatatau, taimi gaioiga, ma isi.
