Blown film thiab cam khwb cia zaj duab xis yog ob txoj kev siv los tsim cov yeeb yaj kiab yas, txhua tus muaj cov yam ntxwv tshwj xeeb thiab kev siv. Nov yog kev sib piv:
Tshuab zaj duab xis
Txheej txheem: Nyob rau hauv tshuab tshuab extrusion, molten yas yog extruded los ntawm ib ncig tuag los ua ib lub raj. Cov raj no ces inflated mus rau hauv npuas, txias, thiab flattened.
Yam ntxwv:Thickness: Feem ntau tsim cov yeeb yaj kiab nrog ntau cov tuab tuab.
Cov khoom: Muab lub zog tensile zoo dua, cuam tshuam tsis kam, thiab yoog raws vim kev taw qhia molecular thaum lub tshuab tshuab.
Daim ntawv thov: Feem ntau siv rau cov khoom ntim, xws li cov hnab ntim khoom noj, cov hnab ntim khoom, thiab cov yeeb yaj kiab ncab.
Cast Film
Txheej txheem: Nyob rau hauv cam khwb cia zaj duab xis extrusion, molten yas yog extruded los ntawm ib tug ca tuag mus rau ib tug chilled nto los yog cov menyuam, qhov twg nws ceev ceev txias thiab solidifies rau hauv ib zaj duab xis.
Yam ntxwv:Thickness: Muaj peev xwm tsim tau cov yeeb yaj kiab nyias nrog zoo meej meej thiab nto tiav.
Cov khoom: Feem ntau muaj lub zog tensile tsawg dua piv rau cov tshuab cua tshuab tab sis muaj qhov pom tseeb zoo dua thiab qis qis dua.
Daim ntawv thov: Feem ntau siv rau ntim khoom noj, cov ntawv lo, thiab cov yeeb yaj kiab tiv thaiv qhov kev pom tseeb yog qhov tseem ceeb.
Cov ntsiab lus ntawm qhov sib txawv
Tsim:
Tshuab zaj duab xis: Tubular tsim inflated rau hauv npuas.
Cast Film: Flat formation ncaj qha nrum rau ntawm qhov chaw.
Lub cev muaj zog:
Tshuab zaj duab xis: Muaj zog thiab yoog raws.
Cast Film: Zoo dua clarity thiab nto tiav.
