Ib tug ntsia hlau yog ib tug extruder, thiab ib tug ntxaib ntsia hlau yog ob extruders
Ib leeg ntsia hlau tsis tuaj yeem ua cov ntaub ntawv sib xyaw, xws li coextrusion membrane: dub thiab dawb daim nyias nyias, uas yog siv los ua cov hnab nthuav qhia lossis cov hnab mis.Vim tias lub hnab nthuav qhia muaj cov khoom tawv lossis ntau yam, cov hnab ntim tau yooj yim tawg, yog li nws tsis yog. siv tau zoo tib yam PE daim nyias nyias, yog li yuav tsum tau coextrusion membrane; coincidentally, lub hnab ntim khoom noj (piv txwv li lub hnab mis) kuj yuav tsum tau ua raws li cov qauv zaub mov thiab tsis yooj yim rau tawg, yog li cov coextrusion membranes yuav tsum tau siv.Dub thiab dawb zaj duab xis belongs rau ob- txheej coextrusion zaj duab xis.Thaum yas yog extruded, ob lub taub hau extrude dub PE zaj duab xis thiab dawb PE zaj duab xis nyob rau tib lub sij hawm.Thaum cov zaj duab xis tseem nyob rau hauv semi-kua lub xeev, nws yog bonded ua ke yam tsis muaj tshuaj xws li kua nplaum. Ib leeg ntsia hlau tsis tau. Ua nws Vim tias cov zaj duab xis sib xyaw yog cov khoom siv pub rau hauv extruder, B khoom pub rau hauv extruder, thiab tom qab ntawd muab tso ua ke ntawm lub taub hau tuag rov qab ntawm extruder los ua ib zaj duab xis sib xyaw.
