Ncab zaj duab xis, raws li cov khoom siv ntim khoom tseem ceeb, yog siv dav hauv logistics, chaw ua yeeb yam, thiab kev tsim khoom lag luam. Nws cov kev ua haujlwm tseem ceeb yog kom qhwv thiab cov khoom lag luam ruaj ntseg los ntawm nws cov khoom siab setcharability thiab tus kheej - cov khoom nplaum. Nws cov qauv tsim qauv, encompassing ntau lub teb suav nrog cov ntaub ntawv science, mechanics, ite engineering, ntsuas kom muaj zog, yoog raws, thiab yooj yim ntawm kev siv.
Los ntawm cov khoom pom zoo, ncab zaj duab xis feem ntau siv cov kab qis qis - ntom cov khoom siv, nrog Copolymerization thiab Purgrification txhim kho thiab purgicination thiab purgrificity txhim kho. Molecular saw kev taw qhia yog qhov tseem ceeb. Thaum lub sijhawm tsim khoom, kho kom ncab kev siv cov kab txuas polymer hauv cov kev taw qhia tshwj xeeb, txhim kho cov yeeb yaj kiab ductility thiab lub zog. Tsis tas li ntawd, ntxiv rau ntawm tus nqi tsim nyog ntawm Metalocene catalyst ua kom zoo heev molecular hnyav faib, kev txhim kho zaj duab xis txuas ntxiv thiab tawv.
In terms of structural design, multi-layer co-extrusion technology is the mainstream approach for stretch film. Los ntawm extruding resins ntawm cov sib txawv ntawm cov khaubncaws sab nraud povtseg, ib qho qauv sib chaws nrog cov khoom gradient yog tsim. Piv txwv li, txheej txheej sab nraud tsom mus rau kev rhuav tshem tawm thiab kho qhov txheej txheem sab hauv txhim kho adhesion thiab anti {{} be} thaiv cov khoom. Qhov kev tsim qauv txheej no tsis tsuas yog txhim kho cov kev ua tau zoo tag nrho tab sis kuj txo cov nqi tsim khoom. Self - cov txiaj ntsig yog lwm tus cwj pwm tseem ceeb ntawm cov yeeb yaj kiab ncab, ua tiav tau los ntawm kev tswj hwm qhov chaw ntawm lub duav rov qab. Nruab nrab adsures ua kom nruj ntawm cov txheej txheem zaj duab xis thaum tsis txhob muaj cov ntawv nplaum nplaum. Tsis tas li ntawd, lub pob tshab thiab glossiness ntawm ncab zaj duab xis yog qhov tswj tau yooj yim kom tau raws li cov kev xav tau ntawm logistics taug qab taug thiab cov khoom lag luam.
Yav tom ntej, ua kev tiv thaiv ib puag ncig nce, bio - raws cov ntaub ntawv thiab biodegradable formations yuav dhau los ua kev tshawb fawb thiab kev tsim kho tau ua ntej. Tsis tas li ntawd, muaj peev xwm nthuav dav cov yeeb yaj kiab tsim, xws li cov uas muaj kev paub txog kev paub txog cov khoom, yuav nthuav nws daim ntawv thov kev xaiv. Cov qauv tsim ntawm cov yeeb yaj kiab ncab txuas ntxiv hloov zuj zus, tsav lub ntim kev lag luam rau kev ua tau zoo thiab ruaj khov.
