Zaj duab xis tshuab tshuab Extrusion Screw chim LDPE HDPE LLDPE

Blown films extrusion yog ib qho ntawm ntau cov txheej txheem tsim polymer. Txoj kev no yog siv los tsim cov khoom lag luam thiab cov yeeb yaj kiab tshwj xeeb polymer uas feem ntau siv rau hauv ntim xws li ntsws, ncab, thaiv cov yeeb yaj kiab (siv los tiv thaiv deli nqaij), ntim khoom noj khov, thiab cov hnab ntim khoom.

Muaj ntau ntau hom polymers uas tuaj yeem siv rau hauv tshuab tshuab extrusion nrog feem ntau yog polypropylene thiab polyethylene (LDPE, HDPE thiab LLDPE). Txoj kev no tuaj yeem tsim cov yeeb yaj kiab monolayer nrog rau ntau cov txheej txheem ntau cov yeeb yaj kiab uas koom nrog co-extrusion los ua ke ntau dua ib qho yas rau hauv ib zaj duab xis.

Muaj ntau qhov zoo ntawm kev tsim cov yeeb yaj kiab siv cov txheej txheem cua tshuab extrusion nrog rau kev muaj peev xwm los tswj cov khoom siv hluav taws xob ntawm cov yas zaum kawg raws li cov txheej txheem thiab cov txheej txheem polymer (s) siv. Piv txwv li, cua tshuab extrusion inflates lub polymer radially thaum tib lub sij hawm kos lub polymer upward nrog rollers. Cov rog no ncab cov polymer nyob rau hauv ob qho tib si transverse thiab kos cov lus qhia, muab lub zog hauv zaj duab xis. Qhov luaj li cas ntawm inflating thiab kos duab tuaj yeem hloov kho kom ua tiav qhov xav tau lub zog nyob rau hauv kev sib hloov thiab kos cov lus qhia ntawm cov khoom kawg. Blown film extrusion kuj muaj ntau yam thiab muaj peev xwm tsim tau ntau yam ntawm ib leeg lossis ntau txheej zaj duab xis nrog ntau yam ntawm zaj duab xis tuab thiab dav.
