Izixhobo zezixhobo zonyango zingahlulwahlulwa zibe ziindidi ezimbini: izixhobo zesinyithi kunye nezixhobo zepolymer. Iimpawu zezinto zesinyithi zizinzile kwaye zinokunyamezelana kakuhle neendlela ezahlukeneyo zokubulala iintsholongwane. Ke ngoko, ukunyamezelana kwezinto zepolymer kuhlala kuqwalaselwa ekukhetheni iindlela zokubulala iintsholongwane. Izixhobo zepolymer zonyango ezisetyenziswa kakhulu kwizixhobo zonyango ikakhulu yi-polyethylene, i-polyvinyl chloride, i-polypropylene, i-polyester, njl.njl., zonke ezinokukwazi ukuzivumelanisa kakuhle nezinto.i-ethylene oxide (EO)indlela yokubulala iintsholongwane.

EOsisibulali-ntsholongwane esibanzi esinokubulala iintsholongwane ezahlukeneyo kubushushu begumbi, kuquka ii-spores, iibhaktheriya zesifo sephepha, iibhaktheriya, iintsholongwane, iifungi, njl. Kubushushu begumbi kunye noxinzelelo,EOyigesi engenambala, inzima kunomoya, kwaye inevumba le-ether elimnandi. Xa ubushushu buphantsi kwe-10.8℃, igesi iyanyibilika ize ibe lulwelo olucacileyo olungenambala kumaqondo obushushu aphantsi. Ingaxutywa namanzi nangayiphi na indlela kwaye inokunyibilika kwizinyibilikisi zendalo ezisetyenziswa rhoqo. Uxinzelelo lomphunga lwe-EO lukhulu kakhulu, ngoko ke lungena ngamandla kwizinto ezicociweyo, lunokungena kwii-micropores luze lufikelele kwinxalenye enzulu yezinto, nto leyo enceda ekucocweni ngokupheleleyo.

Ubushushu bokubulala iintsholongwane

Kwii-ethylene oxidei-sterilizer, intshukumo yeemolekyuli ze-ethylene oxide iyaqina njengoko ubushushu bunyuka, nto leyo enceda ekufikeleleni kwiindawo ezifanelekileyo kunye nokuphucula isiphumo sokubulala iintsholongwane. Nangona kunjalo, kwinkqubo yokwenyani yemveliso, ubushushu bokubulala iintsholongwane abunakwandiswa ngokungenammiselo. Ukongeza ekuqwalaseleni iindleko zamandla, ukusebenza kwezixhobo, njl.njl., impembelelo yobushushu ekusebenzeni kwemveliso nayo kufuneka iqwalaselwe. Ubushushu obuphezulu kakhulu bunokukhawulezisa ukubola kwezinto zepolymer, okubangela iimveliso ezingafanelekiyo okanye ubomi benkonzo obufutshane, njl.njl.Ngoko ke, ubushushu bokubulala iintsholongwane kwi-ethylene oxide buhlala buyi-30-60℃.

Ubuntu bezizalwane

Amanzi athatha inxaxheba kwii-ethylene oxideimpendulo yokubulala iintsholongwane. Kuphela ngokuqinisekisa ukufuma okuthile kwi-sterilizer apho i-ethylene oxide kunye nee-microorganisms zinokusabela kwi-alkylation reaction ukuze kufezekiswe injongo yokubulala iintsholongwane. Kwangaxeshanye, ubukho bamanzi bunokukhawulezisa ukunyuka kwamaqondo obushushu kwi-sterilizer kwaye bukhuthaze ukusasazwa kwamandla obushushu ngokulinganayo.Umswakama othelekisekayo wei-ethylene oxideukubulala iintsholongwane yi-40%-80%.Xa ingaphantsi kwama-30%, kulula ukubangela ukungasebenzi kakuhle kokubulala iintsholongwane.

Ukugxila

Emva kokugqiba ubushushu bokubulala iintsholongwane kunye nomswakama ohambelanayo,i-ethylene oxideUxinzelelo kunye nokusebenza kakuhle kokubulala iintsholongwane ngokubanzi kubonisa impendulo ye-kinetic yokuqala, oko kukuthi, izinga lokusabela liyakhula ngokunyuka koxinzelelo lwe-ethylene oxide kwi-sterilizer. Nangona kunjalo, ukukhula kwayo akunamda.Xa ubushushu budlula i-37°C kwaye uxinzelelo lwe-ethylene oxide lungaphezulu kwe-884 mg/L, lungena kwimeko yokusabela kwe-zero-order., kwaye ii-ethylene oxideUxinzelelo alunampembelelo ingako kwisantya sokusabela.

Ixesha Lokusebenza

Xa kwenziwa uqinisekiso lokubulala iintsholongwane, indlela yesiqingatha somjikelo idla ngokusetyenziswa ukumisela ixesha lokubulala iintsholongwane. Indlela yesiqingatha somjikelo ithetha ukuba xa ezinye iiparameter ngaphandle kwexesha zingatshintshi, ixesha lesenzo liyancitshiswa ngokulandelelana de kufunyanwe ixesha elifutshane lokuba izinto ezicociweyo zifikelele kwimeko yokubulala iintsholongwane. Uvavanyo lokubulala iintsholongwane luphindaphindwa kathathu. Ukuba isiphumo sokubulala iintsholongwane sinokufezekiswa, sinokumiselwa njengesiqingatha somjikelo. Ukuze kuqinisekiswe isiphumo sokubulala iintsholongwane,ixesha lokubulala iintsholongwane eliqikelelweyo kufuneka libe ubuncinane kabini kunesiqingatha somjikelo, kodwa ixesha lesenzo kufuneka libalwe ukususela xa ubushushu, ukufuma,i-ethylene oxideUxinzelelo kunye nezinye iimeko kwisixhobo sokucoca iintsholongwane ziyahlangabezana neemfuno zokubulala iintsholongwane.

Izinto zokupakisha

Iindlela ezahlukeneyo zokubulala iintsholongwane zinemfuno ezahlukeneyo zezinto zokupakisha. Ukulungelelaniswa kwezinto zokupakisha ezisetyenziswa kwinkqubo yokubulala iintsholongwane kufuneka kuqwalaselwe. Izinto zokupakisha ezilungileyo, ingakumbi izinto zokupakisha ezincinci, zinxulumene ngokuthe ngqo nesiphumo sokubulala iintsholongwane se-ethylene oxide. Xa ukhetha izinto zokupakisha, ubuncinane izinto ezinje ngokunyamezela ukubulala iintsholongwane, ukungena komoya, kunye neempawu zokulwa neentsholongwane kufuneka ziqwalaselwe.I-ethylene oxideUkubulala iintsholongwane kufuna ukuba izinto zokupakisha zibe nomoya ovulekileyo.
