Zipangizo zamankhwala zitha kugawidwa m'magulu awiri: zipangizo zachitsulo ndi zipangizo za polima. Kapangidwe ka zipangizo zachitsulo ndi kokhazikika ndipo kamakhala ndi kupirira bwino njira zosiyanasiyana zoyeretsera. Chifukwa chake, kulekerera kwa zipangizo za polima nthawi zambiri kumaganiziridwa posankha njira zoyeretsera. Zipangizo za polima zamankhwala zomwe zimagwiritsidwa ntchito kwambiri pazida zachipatala ndi polyethylene, polyvinyl chloride, polypropylene, polyester, ndi zina zotero, zonse zomwe zimatha kusinthasintha bwino ndi zinthu.okusayidi wa ethylene (EO)njira yoyeretsera.

EOndi mankhwala ophera tizilombo toyambitsa matenda osiyanasiyana omwe amatha kupha tizilombo toyambitsa matenda osiyanasiyana kutentha kwa chipinda, kuphatikizapo spores, mabakiteriya a chifuwa chachikulu, mabakiteriya, mavairasi, bowa, ndi zina zotero. Kutentha kwa chipinda ndi kupanikizika,EONdi mpweya wopanda mtundu, wolemera kuposa mpweya, ndipo uli ndi fungo la ether lonunkhira. Kutentha kukakhala kotsika kuposa 10.8℃, mpweyawo umasungunuka ndikukhala madzi owonekera opanda mtundu pa kutentha kochepa. Ukhoza kusakanizidwa ndi madzi molingana ndi momwe umakhalira ndipo ukhoza kusungunuka mu zosungunulira zachilengedwe zomwe zimagwiritsidwa ntchito nthawi zambiri. Kuthamanga kwa nthunzi ya EO ndi kwakukulu, kotero imalowa mwamphamvu mu zinthu zoyeretsera, imatha kulowa m'ma micropores ndikufikira mbali yakuya ya zinthuzo, zomwe zimathandiza kuti ziwotchedwe bwino.

Kutentha kwa Sterilization

Muokusayidi wa ethyleneChoyeretsera, kuyenda kwa mamolekyulu a ethylene oxide kumawonjezeka pamene kutentha kukukwera, zomwe zimapangitsa kuti zifike ku zigawo zofanana ndikuwonjezera mphamvu yoyeretsera. Komabe, munjira yeniyeni yopangira, kutentha kwa sterilizer sikungakwezedwe kosatha. Kuphatikiza pa kuganizira mtengo wamagetsi, magwiridwe antchito a zida, ndi zina zotero, momwe kutentha kumakhudzira magwiridwe antchito azinthu ziyeneranso kuganiziridwa. Kutentha kwambiri kumatha kufulumizitsa kuwonongeka kwa zinthu za polima, zomwe zimapangitsa kuti zinthu zosayenerera kapena moyo wautumiki ufupikitsidwe, ndi zina zotero.Chifukwa chake, kutentha kwa ethylene oxide sterilization nthawi zambiri kumakhala 30-60℃.

Chinyezi Chaching'ono

Madzi ndi omwe akutenga nawo mbali muokusayidi wa ethylenekuchitapo kanthu poyeretsa. Pokhapokha ngati pali chinyezi china mu sterilizer, ethylene oxide ndi tizilombo toyambitsa matenda tingakumane ndi alkylation reaction kuti tikwaniritse cholinga choyeretsa. Nthawi yomweyo, kupezeka kwa madzi kungathandizenso kukweza kutentha mu sterilizer ndikulimbikitsa kugawa kwa mphamvu ya kutentha mofanana.Chinyezi chaokusayidi wa ethyleneKuyeretsa thupi ndi 40%-80%.Ngati ili yochepera 30%, zimakhala zosavuta kuyambitsa kulephera kwa kuyeretsa.

Kuganizira kwambiri

Pambuyo podziwa kutentha kwa sterilization ndi chinyezi,okusayidi wa ethyleneKuchuluka kwa madzi ndi kuyeretsa bwino nthawi zambiri kumasonyeza kuti munthu amachita zinthu motsatira njira yoyamba, kutanthauza kuti, kuchuluka kwa madzi kumawonjezeka pamene kuchuluka kwa madzi mu sterilizer kumawonjezeka. Komabe, kukula kwake sikuli kopanda malire.Pamene kutentha kwapitirira 37°C ndipo kuchuluka kwa ethylene oxide kuli koposa 884 mg/L, kumalowa mu mkhalidwe wa zero-order reaction.ndiokusayidi wa ethyleneKuchuluka kwa zinthu m'thupi sikukhudza kwambiri kuchuluka kwa zomwe zimachitika.

Nthawi Yochitapo Kanthu

Pochita kutsimikizira kuyeretsa, njira ya theka la kuzungulira nthawi zambiri imagwiritsidwa ntchito kudziwa nthawi yoyeretsa. Njira ya theka la kuzungulira imatanthauza kuti pamene magawo ena kupatula nthawi sasintha, nthawi yochitapo kanthu imachepetsedwa ndi theka motsatizana mpaka nthawi yochepa kwambiri ya zinthu zoyeretsera ifike pamlingo woyeretsa itapezeka. Mayeso oyeretsera amabwerezedwa katatu. Ngati zotsatira za kuyeretsa zitha kupezeka, zitha kudziwika ngati theka la kuzungulira. Pofuna kutsimikizira zotsatira za kuyeretsa,nthawi yeniyeni yoyeretsera iyenera kukhala kawiri kuposa theka la nthawi yoyeretsera, koma nthawi yogwira ntchito iyenera kuwerengedwa kuyambira kutentha, chinyezi,okusayidi wa ethylenekuchuluka kwa madzi ndi zina zomwe zili mu sterilizer zimakwaniritsa zofunikira za sterilizer.

Zipangizo zolongedza

Njira zosiyanasiyana zoyeretsera zimakhala ndi zofunikira zosiyanasiyana pa zipangizo zoyeretsera. Kusinthasintha kwa zipangizo zoyeretsera zomwe zimagwiritsidwa ntchito poyeretsera kuyenera kuganiziridwa. Zipangizo zabwino zoyeretsera, makamaka zipangizo zazing'ono kwambiri zoyeretsera, zimagwirizana mwachindunji ndi mphamvu ya ethylene oxide yoyeretsera. Posankha zipangizo zoyeretsera, zinthu zina monga kulekerera kuyeretsa, kulola mpweya kulowa, ndi mphamvu zophera tizilombo ziyenera kuganiziridwa.Ethylene okusayidiKuyeretsa thupi kumafuna kuti zinthu zopakira zikhale ndi mpweya wokwanira.
