Multilayer coextrusion zaj duab xis
Txhawm rau txuas ntxiv lub neej txee ntawm cov zaub mov, tshuaj thiab lwm yam khoom siv, ntau cov khoom noj thiab tshuaj ntim cov khoom siv tam sim no siv ntau txheej co-extrusion composite films.Tam sim no, muaj ob, peb, tsib, xya, cuaj, thiab kaum ib txheej ntawm cov khoom ntim khoom sib xyaw.Multi-txheej co-extrusion zaj duab xis yog ib zaj duab xis uas extrudes ntau yam ntawm cov ntaub ntawv yas los ntawm ib tug tuag tib lub sij hawm los ntawm ntau raws, uas muaj peev xwm muab kev ua si rau qhov zoo ntawm cov khoom sib txawv.
Multi-layer co-extruded composite zaj duab xis yog tsim los ntawm polyolefin.Tam sim no, cov qauv uas tau siv dav suav nrog: polyethylene / polyethylene, polyethylene / vinyl acetate copolymer / polypropylene, LDPE / nplaum txheej / EVOH / nplaum txheej / LDPE, LDPE / nplaum txheej / EVOH / EVOH / nplaum txheej / LDPE.Lub thickness ntawm txhua txheej tuaj yeem hloov kho los ntawm txheej txheem extrusion.Los ntawm kev kho lub thickness ntawm txheej txheej thiab kev siv ntau yam khoom thaiv, cov yeeb yaj kiab uas muaj qhov sib txawv ntawm cov khoom sib txawv tuaj yeem hloov kho tau yooj yim, thiab cov khoom siv hluav taws xob sib khi kuj tuaj yeem hloov pauv thiab faib kom tau raws li qhov xav tau ntawm cov ntim sib txawv.Qhov no multilayer thiab multi-function co-extrusion compound 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.
