Zinthu za zida zamankhwala zitha kugawidwa m'magulu awiri: zida zachitsulo ndi zida za polymer. Mphamvu za zitsulo ndizokhazikika ndipo zimalekerera kwa njira zosiyanasiyana zosankhira. Chifukwa chake, kulekerera zinthu polima nthawi zambiri kumaganiziridwa pakusankhidwa kwa njira zosankhira. Zomwe zimagwiritsidwa ntchito poimba za polymer zamankhwala za zida zamankhwala zimakhala polyethylene, polyvinyl chloride, polypyerylene, polyester, ndi zina zambiri zomwe zimasinthidwa ndi zomwe zimasinthidwa ndiethylene oxide (eo)Njira yosinthira.

EOndi owoneka bwino kwambiri omwe amatha kupha tizilombo tosiyanasiyana mwa firiji, kuphatikizapo spores, mabakiteriya, ma viabites, mafakitale,EOndi mpweya wopanda utoto, wolemera kuposa mpweya, ndipo ali ndi fungo labwino. Kutentha kumakhala kotsika kuposa 10.8 ℃, ufa wamagesi ndikukhala madzi opanda moto pamiyala yotsika. Itha kusakanikirana ndi madzi mofananira iliyonse ndipo imasungunuka komwe nthawi zambiri imagwiritsidwa ntchito osinthika. Kukakamizidwa kwa eor ya eo ndi yayikulu, motero kumalowa mwamphamvu zinthu zosawilitsidwa, kumatha kulowa maimidwe ndi micropores ndikufika pamtunda wa zinthuzo, zomwe zimapangitsa kutsatsa bwino.

Kutentha Kwambiri

Muethylene oxideMsuriwo, kayendedwe ka ethylene oxide oxide mamolekyu akukwera pamene kutentha kumakwera, komwe kumapangitsa kuti zizigwira ntchito yofananira ndikusintha njira yodulira. Komabe, popanga zenizeni, Kutentha kotsetsetsa kusakulitsidwa kwamuyaya. Kuphatikiza pa kulingalira kwa mphamvu, zida zamagetsi, ndi zina. Kutentha kwambiri kumatha kuthamangitsa kuwonongeka kwa zida za polymer, zomwe zimapangitsa kuti pakhale zinthu zosachepera kapena moyo waufupi, etc.Chifukwa chake, kutentha kosasintha kwa ethylee birilization nthawi zambiri kumakhala 30-60 ℃.

Chinyezi

Madzi ndi omwe amatenga nawo mbali muethylene oxidekutengera kutengera. Pokhapokha ndikuwonetsetsa kuti wachibale wina ndi chinyezi cha mawu a ethylene o oxide ndi tizilombo tating'onoting'ono tomwe timakwaniritsa cholinga cha chosankha. Nthawi yomweyo, kupezeka kwa madzi kumathandiziranso kutentha kumakwera mu salemu ndikulimbikitsa kugawa yunifolomu ya kutentha kwa kutentha.Chinyezi chaethylene oxideOtsatsa ndi 40% -80%.Ikakhala yotsika 30%, ndikosavuta kubweretsa kulephera.

Kolimbikira

Pambuyo posankha kutentha kosinthika ndi chinyezi chochepa,ethylene oxideKugwiritsa ntchito bwino komanso kusinthasintha kugwira ntchito nthawi zambiri kumawonetsa chiwonetsero choyamba cha kinetic, kuti, kuchuluka kwa ethylene maxisisi kukhazikika kwa sterration. Komabe, kukula kwake sikopanda malire.Kutentha kumapitilira 37 ° C ndi ethylene oxide kuwunikira kwambiri kuposa 884 mg / l, kumalowa mkhalidwe wa zero-wordore, ndiethylene oxideNgozi imakhudza kwambiri kuchuluka kwa zomwe zingachitike.

Phunziro

Mukamachita kutsimikizika, njira yozungulira theka imagwiritsidwa ntchito pofuna kudziwa nthawi yosinthira. Njira yozungulira yozungulira imatanthawuza kuti magawo ena kupatula nthawi yosasinthika, nthawi yochitapo kanthu itakhazikika mpaka nthawi yochepa kwambiri kwa zinthu zosasunthika kuti zitheke. Kuyesa kowiritsa kumabwerezedwa katatu. Ngati chosasunthika chingachitike, chimatha kutsimikizika ngati theka-kuzungulira pakati. Kuti muwonetsetse stewalization zotsatira,Nthawi yeniyeni yosinthira iyenera kukhala yosachepera kawiri konse, koma nthawi yake iyenera kuwerengedwa pomwe kutentha, chinyezi chowerengeka,ethylene oxideKukhazikika kwa mikhalidwe ina mu snteriter kumakumana ndi zomwe zimachitika.

Zipangizo Zopangira

Njira zophatikizira zosiyanasiyana zimakhala ndi zofunikira zosiyanasiyana pakupanga zida za ma CD. Kusintha kwa zinthu zomwe zimagwiritsidwa ntchito potengera njira yosinthira ziyenera kuganiziridwa. Zipangizo zabwino za paDakulu, makamaka zopangira zazing'onoting'ono kwambiri, zimagwirizana mwachindunji ndi chosasunthika za ethylene oxide. Mukamasankha zida za ma CDCaging, osachepera zinthu monga chosasunthika, kukhazikika kwa mpweya, ndi antibacterial kuyenera kulingaliridwa.Ethylene oxideOtsanula amafunikira zida zapamalo kuti zikhale ndi mpweya wina.
