Txhawm rau hloov mus rau ntau yam kev ntim khoom ntawm stretch zaj duab xis, ntau txheej co-extrusion zaj duab xis tshuab tshuab tau nthuav tawm, tsuas yog tuaj yeem tshuab ntau txheej yas zaj duab xis, yog li dab tsi yog qhov zoo ntawm stretch zaj duab xis nrog ntau txheej?
Cov yeeb yaj kiab uas muaj ntau txheej tsuas yog tsim rau tshuab-pob cam khwb cia zaj duab xis. Tes-pob tshuab ncab zaj duab xis muaj ib mus rau peb txheej ntawm LLDPE blends uas muaj kim cling lick additives tsis siv nyob rau hauv cam khwb cia films.
Cov yeeb yaj kiab uas muaj ntau txheej feem ntau tsis muaj cov khoom sib txawv. Separating ib tug resin kwj mus rau hauv nplooj ntawv stacked ua ke ua rau cov nplooj ntawv seem nyob rau hauv feedblock. Cov tshuab no feem ntau yog siv rau hauv daim ntawv extrusion kom ua tiav cov khoom sib txawv ntau dua.
Hloov cov txheej nyias ntawm kev lag luam extrusion tuaj yeem txhim kho lub zog pinhole. Extruding metallocene resins thinner ua rau lawv tsis tshua muaj kev tawg, ib yam li iav.
Tib lub cuaj-txheej zaj duab xis li plywood muaj ntau dua pre-stretch, pinhole lub zog thiab tsim kua muag tsis kam tshaj tsib-txheej zaj duab xis.
Cov txheej nyias nyias ntawm mLLDPE kuj tseem ua rau muaj kev siv ntau dua ntawm cov yeeb yaj kiab uas tsis tshua muaj nqi thiab txo qhov xav tau ntawm mLLDPE. Cov ntsiab lus metallocene poob mus rau 33 feem pua hauv xya-txheej zaj duab xis nrog peb txheej mLLDPE.
Kuj tseem muaj kev tsis sib haum xeeb txog kev siv ntau extruders thaum muaj qhov laj thawj zoo rau lub feedblock los tsim ntau txheej txheej los ntawm ib qho kwj dej. Siv ob lub extruders rau ib txheej nyias ntawm ib qho resin ua rau cov khoom tso tawm ntawm txoj kab, tab sis tsis cuam tshuam rau zaj duab xis ua haujlwm. High-volume ntau lawm kab nrog ob 4.5 "extruders es tsis txhob ntawm ib tug 6" extruder kuj muab tau yooj yim rau zus tau tej cov complex los yog yooj yim cov khoom, nrog kub tswj ntawm 4.5 "extruders piv rau 6" extruders Lub extruder yog ntau yooj yim.
