Blown film yog ib txoj kev ua cov yas, uas yog hais txog cov txheej txheem uas cov resin yog rhuab thiab melted thiab ces tshuab mus rau hauv ib zaj duab xis yas.Cov zaj duab xis uas tsim los ntawm cov kws tshaj lij zaj duab xis tshuab tshuab yog dav siv hauv kev lag luam xws li kev khaws cia tshiab, noo noo-pov thawj, thiab oxygen barrier.Tus nqi ntawm zaj duab xis tshuab nrog cov khoom siv tshiab yog siab dua.Cov yeeb yaj kiab ua los ntawm cov khoom siv yas rov siv dua uas siv ob zaug lossis ntau dua ob zaug muaj xim tsis sib xws, nkig thiab tawg.Txawm hais tias tus nqi qis dua, tus nqi muag kuj tseem qis vim yog xim ntawm cov khoom.
Peb siv PE tshuab zaj duab xis ua piv txwv.Cov yas zaj duab xis tshuab tawm ntawm lub hom phiaj uas tsis tshua muaj siab PE (LDPE) thiab linear low-density PE (LLDPE) siv hauv kev rov ua dua tshiab muaj ntau yam khoom xws li xim dawb thiab gloss vim cov khoom siv teeb meem.Nws tsis txaus siab, yog li qhov siv tau ntau yam txo qis heev.Tshuab zaj duab xis nrog PE cov khoom yas uas tau siv dua ob zaug, thiab ntxiv fluorescent whitening tus neeg sawv cev thaum lub sijhawm tsim khoom, tuaj yeem ua rau cov xim ntawm cov yas zaj duab xis ntau dua translucent.
Siv hom kev pom zoo ntawm qhov muag teeb pom kev zoo rau lub tshuab cua tshuab ntawm LDPE thiab LLDPE tuaj yeem txhim kho qhov tsis sib xws ntawm cov tshuab cua tshuab thiab cov xim tsis zoo thiab luster.Nws tseem muaj zog dua thaum siv ntawm HDPE zaj duab xis.Covfluorescent whitening agent refined OBuas yog tsim nyog rau cov tshuab cua tshuab manufacturers tuaj yeem txhim kho qhov teeb meem tsis txaus whiteness thiab ci ntsa iab ntawm cov khoom los ntawm cov yas tshuab tshuab manufacturers kom txo cov nqi thiab siv cov khoom siv rov qab.Thaum ntxivfluorescent whitening tus neeg sawv cevtxhawm rau kho OB, ua raws li cov lus pom zoo ntawm cov kws tshaj lij engineers tom qab kev debugging, thiab cov yeeb yaj kiab uas tsim tawm tuaj yeem muaj qhov zoo nkauj zoo nkauj, siab pob tshab thiab ci ntsa iab.Yog li ntawd, lub brightener no daws qhov teeb meem ntawm ntau lub tshuab cua tshuab manufacturers thiab txo tus nqi ntau.Nws yog nyiam los ntawm cov tshuab ua yeeb yaj kiab loj hauv tsev thiab txawv teb chaws.
