Inzuzo ye-EVOH Kafushane

Izinzuzo ze-EVOH Kafushane: Isithiyo se-EVOH kube yinto esetshenziswa kakhulu. Lolu hlobo lwezinto zefilimu ngaphezu kohlobo olunganwetshiwe, kukhona uhlobo lwe-aluminium olunezinhlangothi ezimbili, uhlobo lwe-aluminium olufakwe umhwamuko, uhlobo lwe-adhesive coating, Ukwelula kwezindlela ezimbili kukhona ukupakishwa okungamelana nokushisa kwemikhiqizo eyinyumba. Izakhiwo zesithiyo ze-EVOH ngokuya ngokuqukethwe kwe-ethylene, njengoba okuqukethwe kwe-ethylene kukhula ngokujwayelekile, izakhiwo zokuvimbela igesi ziyancipha, kepha ukucutshungulwa kalula. Isici esiphawulekayo se-EVOH yizakhiwo ezinhle kakhulu zokuvimbela igesi kanye nokucutshungulwa okuhle kakhulu, ngaphezu kokubonakala obala, isicwebezelisi, amandla emishini, ukuguquguquka, ukumelana nemihuzuko, ukumelana nokubanda namandla angaphezulu kuhle kakhulu. Emkhakheni wokupakisha, isendlalelo sesithiyo se-EVOH esenziwe nge-membrane eyinhlanganisela ephakathi, esetshenziswa kuwo wonke amaphakheji aqinile futhi athambile; ukufakwa kwe-aseptic embonini yokudla, ibhodwe elishisayo nezikhwama zokupheka, ukupakisha imikhiqizo yobisi, inyama, amajusi ezithelo ezisemathinini Kanye nama-condiments; imikhiqizo okungekona ukudla, ukupakishwa kwezinyibilikisi, izibulala-zinambuzane, amakhemikhali, isakhiwo esine-air-conditioning, esifakwe imiphongolo kaphethiloli, nezinye izakhi zikagesi. Emaphaketheni okudla, isitsha sepulasitiki se-EVOH singangena esikhundleni sezitsha zengilazi nezensimbi, izinkampani ezifuywayo zezilwane zasemanzini zithumela ukudla kwasolwandle ngokusetshenziswa kwe-PE / EVOH / PA / RVOH / PE ye-five-layer co-extruded vacuum packaging yefilimu. Ukusheshisa ulwelwesi oluyinhlanganisela lwe-EVOH ngenkathi nokufunda phesheya i-EVOH stretch orientation, izakhiwo ezintsha zokuvimbela igesi Ifilimu ye-EVOH ukusebenza ngokuphindwe kathathu kwefilimu ye-EVOH enganwetshiwe ekhona. Ukwengeza i-EVOH njengento yokuvimbela ingasetshenziswa futhi kwezinye izinto zokupakisha ze-resin zokwenziwa, zisebenza ukuqinisa umphumela wezakhiwo zokuvimbela.

Isifinyezo esifushane sezinzuzo ze-EVOH:

▪Ngaphansi komswakamo ophansi indawo inganikeza ukusebenza komgoqo ophezulu

▪Umphumela omuhle wokuvinjwa kwamakhemikhali, okuhlanganisa iningi lamafutha namafutha, ama-acids nezibulala-zinambuzane ezincibilikisayo.

▪Ukungafihli Okuphezulu: ukuqinisekisa ukusebenza kalula kokuqaliswa

▪Iphunga elimnandi, ukunambitheka okuhle

▪I-EVOH enama-polymer ahlukahlukene ukuze kuzuzwe i-coextrusion
