EVOH Teeb Meem Daim Ntawv Thov Kev Siv

EVOH barrier zaj duab xis tau yog cov khoom siv dav siv ntau tshaj plaws


EVOH barrier zaj duab xis tau yog cov khoom siv dav siv ntau tshaj plaws. Cov khoom siv zaj duab xis no ntxiv rau hom tsis-stretched, muaj ob-txoj kev ncab, vapor-deposited aluminium hom, nplaum txheej hom, ob-txoj kev ncab muaj cov khoom ntim cov khoom tsis muaj cua sov.


EVOH barrier zog barrier zaj duab xis nyob ntawm seb cov ntsiab lus ntawm ethylene, raws li cov ntsiab lus ethylene nce nyob rau hauv feem ntau, cov roj barrier zog txo, tab sis qhov yooj yim ntawm kev ua.

Qhov tseem ceeb tshaj plaws yog EVOH barrier zaj duab xis uas muaj cov khoom siv roj zoo heev thiab kev ua haujlwm zoo, ntxiv rau cov pob tshab, gloss, txhua yam muaj zog, yoog raws, tsis kam tiv taus, txias tsis kam thiab lub zog saum npoo zoo heev. Hauv kev ntim khoom, EVOH txheej txheej txheej ua los ntawm cov khoom sib xyaw ua ke nruab nrab, siv tag nrho cov ntim tawv thiab mos; rau kev ntim aseptic hauv kev lag luam khoom noj, lub lauj kaub kub thiab lub hnab ua noj, ntim cov khoom noj siv mis, nqaij, cov kua txiv hmab txiv ntoo hauv kaus poom thiab seasoning; cov khoom tsis yog khoom noj khoom haus, ntim rau cov kuab tshuaj, tshuaj, cov qauv cua txias, kab nrog cov thoob roj av, thiab lwm yam khoom siv hluav taws xob. Hauv kev ntim khoom noj, EVOH yas thawv tuaj yeem hloov cov iav thiab cov thawv hlau, cov tuam txhab aquaculture hauv tsev xa tawm cov nqaij nruab deg ntawm kev siv PE / EVOH / PA / RVOH / PE tsib-txheej co-extruded film nqus ntim. Accelerating EVOH composite membrane thaum tseem kawm txawv teb chaws EVOH stretch orientation, cov roj barrier tshiab ntawm EVOH zaj duab xis yog peb zaug qhov kev ua tau zoo ntawm cov uas twb muaj lawm tsis-stretched EVOH zaj duab xis. Tsis tas li ntawd, EVOH raws li cov khoom siv barrier kuj tuaj yeem coated rau lwm cov khoom siv hluavtaws resin ntim, pab txhawb cov nyhuv ntawm cov khoom thaiv.
