Co-extruded zaj duab xis yog siv rau hauv cov hnab mis ntshiab, hnab nthuav qhia, thiab cov yeeb yaj kiab tiv thaiv hlau. Nws yog characterized los ntawm zoo tensile zog thiab zoo nto brightness.
Taw qhia:
Hauv kev ua cov yeeb yaj kiab, cov khoom siv raw yog extruded mus rau lwm cov yeeb yaj kiab uas tau ua, lossis cov yeeb yaj kiab sib txawv uas tau tsim tau raug sib koom ua ke los ua ntau hom - txheej zaj duab xis. Cov khoom no yog hu ua zaj duab xis sib xyaw. Cov khoom siv ntawm cov zaj duab xis yog feem ntau yog yas, tab sis cov ntawv, hlau ntawv (feem ntau yog txhuas) los yog ntaub kuj siv tau. Qhov tseem ceeb ntawm cov zaj duab xis sib xyaw yog kom muaj kev sib raug zoo ntawm cov khaubncaws sab nraud povtseg kom ntseeg tau tias tag nrho cov khoom siv ntawm lub ntim. Tsis tas li ntawd, cov yeeb yaj kiab sib xyaw feem ntau yog siv rau kev ntim khoom noj, thiab cov nplaum nplaum yog siv rau hauv kev ua cov yeeb yaj kiab sib xyaw, thiab kev xaiv cov kuab tshuaj thiab cov txheej txheem sib txuas yuav tsum ua raws li cov qauv kev tu cev. Co-cov yeeb yaj kiab extruded muaj feem ntau ntawm cov yam ntxwv ntawm cov yeeb yaj kiab sib xyaw, tab sis nrog ib qho sib txawv, tias txhua txheej ntawm co-extruded films yog extruded tib lub sijhawm, yog li yuav tsis muaj lwm yam uas tsis yog{{ 3}}cov ntaub ntawv yas xws li txhuas ntawv ci, ntawv, thiab lwm yam. Kev sib xyaw ntawm cov khoom siv yog qhov me me, thiab cov peev txheej ntawm daim ntawv thov kuj me me. Txawm li cas los xij, vim tias lub caij ntuj no cov khaubncaws sab nraud povtseg yog sib koom ua ke los ntawm kub yaj yam tsis muaj cov nplaum, kev nyab xeeb kev nyab xeeb ntawm co-extruded zaj duab xis rau ntim khoom noj yog qhov txhim khu kev qha.
