Cov qauv ntawmmultilayer co-extruded filmstuaj yeem muab faib ua ob pawg, uas yog cov qauv sib luag (A / B / A) thiab cov qauv asymmetric (A / B / C).Tam sim no, cov yeeb yaj kiab hauv Suav teb feem ntau yog tsim los ntawm 5 txheej, 7 txheej, 8 txheej thiab 9 txheej.Lub symmetrical structural txheej ntawmmultilayer co-extrusion barrierdiaphragm yog tsim los ntawm peb hom kev ua haujlwm txheej, uas yog txheej txheej txheej, nplaum txheej thiab txheej txhawb nqa.
Barrier txheej: txheej txheej barrier muaj kev ua haujlwm ntawm oxygen tsis kam, noo noo tiv thaiv thiab tiv thaiv roj to.Los ntawm kev tswj hwm cov ntaub ntawv txheej txheej thiab cov tuab, cov khoom thaiv kev ua haujlwm ntawm cov ntaub ntawv zaj duab xis tuaj yeem hloov kho kom tau raws li cov kev xav tau ntim sib txawv (cov ntaub ntawv thaiv feem ntau siv hauv khw suav nrog PA, EVOH, PVDC, thiab lwm yam.
Txhawb txheej: feem ntau, symmetrical structural cov ntaub ntawv muaj ob txheej txhawb nqa.Cov txheej txheej sab hauv yog siv rau cov cua sov sealing, uas yog txheej txheej thaum tshav kub kub sealing, thaum lub txheej txheej yog ncaj qha siv raws li txheej txheej los yog luam ntawv txheej ntawm lub ntim zaj duab xis.Cov txheej txheem txhawb nqa yuav tsum muaj lub zog zoo txhua yam, kev ua haujlwm kub sealing, dej vapor tsis kam, pob tshab thiab luam tawm.Cov khoom siv ntawm cov txheej no yog LDPE lossis LDPE / LLDPE cov ntaub ntawv sib xyaw.
Bonding txheej: lub luag hauj lwm ntawm kev sib khi txheej yog los khi cov txheej thaiv txheej thiab cov txheej txheem txhawb nqa los xyuas kom meej lub zog ntawm cov txheej txheem.Kev xaiv ntawm cov khoom siv sib txuas thiab cov tuab feem ntau yog nyob ntawm cov ntaub ntawv ntawm cov txheej txheem kev txhawb nqa thiab txheej txheej thaiv thiab qhov yuav tsum tau muaj lub zog sib txuas los txiav txim siab cov khoom siv nplaum siv rau txheej txheej.
Nyob rau tib lub sijhawm, lub thickness ntawm txhua txheej tuaj yeem hloov kho los ntawm cov txheej txheem extrusion.Los ntawm kev kho lub thickness ntawm txheej txheej thiab qhov kev faib ua feem ntawm cov ntaub ntawv raw, cov yeeb yaj kiab nrog cov khoom sib txawv tuaj yeem ua tau yooj yim.Cov ntaub ntawv kub-sealing txheej kuj tuaj yeem hloov thiab hloov kho kom tau raws li qhov xav tau ntawm cov ntim sib txawv.Lub multilayer thiab multi-functional co-extrusion composite yog lub ntsiab kev taw qhia ntawm kev loj hlob ntawm ntim zaj duab xis cov ntaub ntawv nyob rau hauv lub neej yav tom ntej.
Txhawm rau txuas ntxiv lub neej txee ntawm cov khoom noj tam sim no thiab ntim tshuaj, ntau cov ntaub ntawv ntim khoom siv ntau txheej co-extruded composite films.Hauv daim ntawv thov, nws ua kom pom cov yam ntxwv zoo ntawm kev ruaj ntseg zoo, kev cia txias, kev tiv thaiv saj, lub neej ntev txee, acid thiab alkali tsis kam, noo noo thiab txias tsis kam, kub tsis kam, tsis kub thiab txias cia tsis kam, thiab muaj zog heev.
