Cov Lus Qhia Txog Qhov Zoo ntawm EVOH

Cov txiaj ntsig ntawm EVOH: Cov khoom thaiv EVOH yog cov khoom siv dav tshaj plaws. Ntxiv rau hom khoom siv zaj duab xis no, muaj ob txoj kev ncab, hom txhuas uas tso pa tawm, hom nplaum txheej, thiab ob txoj kev ncab kuj muaj cov ntim khoom uas tiv taus cua sov rau cov khoom tsis muaj kab mob. Cov yam ntxwv ntawm EVOH nyob ntawm cov ntsiab lus ntawm ethylene, thaum cov ntsiab lus ntawm ethylene nce ntxiv, cov yam ntxwv ntawm cov pa roj txo qis, tab sis qhov yooj yim ntawm kev ua. EVOH qhov tseem ceeb yog cov yam ntxwv ntawm cov pa roj zoo heev thiab kev ua haujlwm zoo heev, ntxiv rau qhov pom tseeb, ci ntsa iab, lub zog kho tshuab, kev ywj pheej, kev tiv taus kev sib txhuam, kev tiv taus txias thiab lub zog ntawm qhov chaw zoo heev. Hauv kev ntim khoom, EVOH txheej thaiv ua los ntawm cov ntaub ntawv sib xyaw ua ke, siv rau txhua yam ntim khoom tawv thiab mos; rau kev ntim khoom aseptic hauv kev lag luam zaub mov, lauj kaub kub thiab hnab ua noj, ntim khoom noj mis nyuj, nqaij, kua txiv hmab txiv ntoo hauv kaus poom thiab cov khoom qab zib; cov khoom tsis yog khoom noj, ntim rau cov kuab tshuaj, tshuaj tua kab, tshuaj, cov qauv cua txias, kab nrog cov thoob roj av, thiab lwm yam khoom siv hluav taws xob. Hauv kev ntim khoom noj, lub thawv yas EVOH tuaj yeem hloov cov thawv iav thiab hlau, cov tuam txhab ua liaj ua teb hauv tsev xa khoom noj hiav txwv los ntawm kev siv PE / EVOH / PA / RVOH / PE tsib txheej co-extruded zaj duab xis nqus tsev ntim. Ua kom nrawm dua EVOH composite membrane thaum tseem kawm txawv teb chaws EVOH ncab kev taw qhia, cov khoom siv roj tshiab ntawm EVOH zaj duab xis yog peb zaug ntawm kev ua tau zoo ntawm cov yeeb yaj kiab EVOH uas twb muaj lawm uas tsis ncab. Tsis tas li ntawd, EVOH ua cov khoom thaiv kuj tseem siv tau rau lwm cov ntaub ntawv ntim khoom siv hluavtaws, pab txhawb kom muaj zog ntawm cov khoom thaiv.

Cov ntsiab lus luv luv ntawm qhov zoo ntawm EVOH:

▪Nyob rau hauv qhov chaw tsis muaj av noo tuaj yeem muab kev ua tau zoo heev

▪Cov tshuaj lom neeg zoo thaiv cov teebmeem, suav nrog feem ntau ntawm cov rog thiab roj, cov kua qaub thiab cov tshuaj tua kab.

▪Kev Pom Tseeb Siab: kom ntseeg tau tias kev ua haujlwm yooj yim ntawm kev siv

▪Tsw qab, saj zoo

▪EVOH nrog ntau yam polymers kom ua tiav coextrusion
