EVOH cov khoom, tseem hu ua ethylene vinyl cawv copolymer, yog cov khoom siv yas uas muaj ntau yam zoo.Ib qho ntawm cov lus nug tseem ceeb uas feem ntau nug yog seb cov khoom siv EVOH puas tuaj yeem siv los tsim lub raj mis.
Cov lus teb luv luv yog yog.EVOH cov ntaub ntawv yog siv los tsim ntau hom ntim, suav nrog lub raj mis.Nws cov yam ntxwv tshwj xeeb ua rau nws xaiv zoo rau daim ntawv thov no.
Ib qho txiaj ntsig tseem ceeb ntawm kev siv EVOH rau kev tsim lub raj mis yog nws cov khoom thaiv zoo heev.EVOH muaj cov qauv me me uas ua rau nws tiv taus cov pa thiab vapor kis.Qhov no txhais tau hais tias cov fwj ua los ntawm EVOH tuaj yeem tswj tau qhov tshiab thiab tsw ntawm lawv cov ntsiab lus ntev.
Lwm qhov zoo dua ntawm EVOH yog nws cov pob tshab zoo heev.Cov tsos ntawm lub raj mis ua los ntawm cov khoom siv EVOH yog crystal ntshiab, thiab cov neeg siv khoom tuaj yeem pom cov khoom hauv lub raj mis yooj yim.Qhov no yog ib qho tseem ceeb tshwj xeeb tshaj yog rau cov khoom ntim ntim uas tso siab rau qhov pom kev pom zoo kom nyiam cov neeg siv khoom.
EVOH cov ntaub ntawv kuj tseem tiv taus qhov cuam tshuam thiab kev puas tsuaj, ua rau lawv zoo tagnrho rau ntim khoom noj thiab dej haus.Lub raj mis ua los ntawm EVOH muaj lub neej ntev, uas muaj txiaj ntsig zoo rau cov neeg siv khoom uas xav rov siv dua lossis rov ua dua lub raj mis.
Ntxiv rau tag nrho cov txiaj ntsig no, EVOH cov ntaub ntawv kuj tseem ceeb heev rau cov txheej txheem tsim khoom tshiab.Qhov no txhais tau tias nws tuaj yeem ua tau sai thiab yooj yim molded rau hauv ntau yam duab thiab qhov ntau thiab tsawg kom tau raws li cov qauv tsim tshwj xeeb.
Hauv cov ntsiab lus, cov khoom siv EVOH tuaj yeem ua rau hauv lub raj mis thiab yog qhov kev xaiv zoo tshaj plaws rau daim ntawv thov no.Nws muab cov khoom thaiv zoo heev, clarity, durability thiab formability, ua rau nws yog ib qho kev xaiv txaus nyiam rau kev lag luam ntim khoom.Txawm hais tias koj tab tom nrhiav tus nqi tsim nyog thiab kev daws teeb meem yooj yim, lossis cov khoom lag luam siab nrog cov yam ntxwv siab, EVOH cov ntaub ntawv tuaj yeem ua tau raws li koj xav tau.
