Izinto zezixhobo zonyango zinokuhlulwa ngokulinganayo zibe ngamacandelo amabini: izinto zetsimbi kunye nezixhobo zepolymer. Iimpawu zezinto zetsimbi zizinzile kwaye zinyamezela kakuhle kwiindlela ezahlukeneyo zokuvala inzala. Ke ngoko, ukunyamezelana kwezixhobo zepolymer kudla ngokuqwalaselwa ekukhetheni iindlela zokuvala inzala. Izinto ezisetyenziswa zonyango zepolymer kwizixhobo zonyango ikakhulu yi-polyethylene, i-polyvinyl chloride, i-polypropylene, i-polyester, njl., zonke ezinokuguquguquka kwezinto eziphathekayoi-ethylene oxide (EO)indlela yokuvala inzala.

EOsisibulala-ntsholongwane esinokubulala iintsholongwane ezahlukeneyo kwiqondo lobushushu begumbi, kubandakanywa iintsholongwane, iintsholongwane zesifo sephepha, ibhaktiriya, iintsholongwane, umngundo, njl. Kwiqondo lobushushu begumbi kunye noxinzelelo,EOyigesi engenambala, inzima kunomoya, kwaye inevumba elimnandi leether. Xa iqondo lobushushu lingaphantsi kwe-10.8℃, irhasi iyanyibilika kwaye ibe lulwelo olungenambala olucacileyo kumaqondo aphantsi. Inokuxutywa namanzi nakweyiphi na imilinganiselo kwaye inokunyibilika kwii-solvents eziphilayo ezisetyenziswa ngokuqhelekileyo. Uxinzelelo lomphunga we-EO mkhulu, ngoko unokungena okunamandla kwizinto ezihlambulukileyo, unokungena kwi-micropores kwaye ufikelele kwindawo enzulu yezinto, ehambelana nokuvalwa ngokucokisekileyo.

Ubushushu bokwenza inzala

Kwiethylene oxidei-sterilizer, ukuhamba kwee-ethylene oxide molecules kuqinisa njengoko ubushushu bukhuphuka, obulungele ukufikelela kwayo kwiindawo ezihambelanayo kunye nokuphucula umphumo we-sterilization. Nangona kunjalo, kwinkqubo yokuvelisa ngokwenene, ubushushu bokwenza inzala abunakunyuswa ngokungenammiselo. Ukongeza ekuqwalaseleni iindleko zamandla, ukusebenza kwezixhobo, njl., impembelelo yeqondo lokushisa ekusebenzeni kwemveliso kufuneka nayo ithathelwe ingqalelo. Ukushisa okuphezulu kakhulu kunokukhawulezisa ukubola kwezixhobo zepolymer, okukhokelela kwiimveliso ezingafanelekanga okanye ubomi obufutshane benkonzo, njl.Ke ngoko, ubushushu be-ethylene oxide sterilization buhlala bungama-30-60 ℃.

Ubuntu bezizalwane

Amanzi athatha inxaxheba kwiethylene oxideimpendulo yokuvala inzala. Kuphela ngokuqinisekisa ukufuma okuthile kwisibulali-ntsholongwane apho i-ethylene oxide kunye ne-microorganisms zingena kwi-alkylation reaction ukufezekisa injongo yokuvala inzala. Ngexesha elifanayo, ubukho bamanzi bunokukhawulezisa ukunyuka kweqondo lokushisa kwi-sterilizer kunye nokukhuthaza ukusabalalisa okufanayo kwamandla obushushu.Ukufuma okunxulumene neethylene oxideukuvala inzala ngama-40% -80%.Xa ingaphantsi kwe-30%, kulula ukubangela ukusilela kokuvala inzala.

Ukugxila

Emva kokumisela ubushushu bokuvala inzala kunye nokufuma okuhambelanayo, iethylene oxideUxinzelelo kunye nempumelelo yokuvala inzala ngokuqhelekileyo ibonisa ukusabela kwe-kinetic yomyalelo wokuqala, oko kukuthi, izinga lokusabela liyenyuka ngokunyuka kwe-ethylene oxide yoxinaniso kwisibulali-ntsholongwane. Noko ke, ukukhula kwayo akunasiphelo.Xa ubushushu budlula i-37°C kunye ne-ethylene oxide concentration ingaphezulu kwe-884 mg/L, ingena kwi-zero-order reaction state., kwaye iethylene oxideUgxininiso lunempembelelo encinci kwireyithi yokusabela.

Ixesha lokuSebenza

Xa uqinisekisa ukuvala inzala, indlela yesiqingatha somjikelezo idla ngokusetyenziswa ukumisela ixesha lokuvala inzala. Indlela yesiqingatha somjikelo ithetha ukuba xa ezinye iiparameters ngaphandle kwexesha zihlala zingatshintshi, ixesha lesenzo liqikelelwa ngesiqingatha ngokulandelelana kude kube lelona xesha lifutshane lokuba izinto ezizintsholongwane zifikelele kwisimo esingenazintsholongwane. Uvavanyo lokuvala inzala luphindaphindwa amaxesha ama-3. Ukuba isiphumo sokuvala inzala sinokufumaneka, sinokumiselwa njengesiqingatha somjikelo. Ukuqinisekisa isiphumo sokuvala inzala,elona xesha lokuvala inzala elimiselweyo kufuneka libe kabini ubuncinane kumjikelo wesiqingatha, kodwa ixesha lesenzo kufuneka libalwe ukusuka xa iqondo lobushushu, ukufuma okuhambelanayo,ethylene oxideUgxininiso kunye nezinye iimeko kwi-sterilizer ziyahlangabezana neemfuno zokuvala inzala.

Izinto zokupakisha

Iindlela ezahlukeneyo zokuvala inzala zineemfuno ezahlukeneyo zemathiriyeli yokupakisha. Ukulungelelaniswa kwezinto zokupakisha ezisetyenziselwa inkqubo yokuvala inzala kufuneka kuthathelwe ingqalelo. Izinto zokupakisha ezilungileyo, ngakumbi ezona zinto zincinci zokupakisha, zihambelana ngokuthe ngqo nefuthe le-ethylene oxide. Xa ukhetha izinto zokupakisha, ubuncinci izinto ezifana nokunyamezela inzala, ukunyanzeliswa komoya, kunye neempawu zokulwa ne-antibacterial kufuneka ziqwalaselwe.I-ethylene oxideukuvala inzala kufuna izinto zokupakisha ukuba zibenokungena komoya okuthile.
