Polyethylene (PE) tshuab zaj duab xis ntau lawm yog cov txheej txheem tsim khoom siv dav siv los tsim cov yeeb yaj kiab yas siv hauv ntim, kev ua liaj ua teb, thiab kev tsim kho. Cov txheej txheem cuam tshuam nrog extruding molten PE los ntawm lub voj voog tuag, inflating nws mus rau hauv npuas, thiab tom qab ntawd txias thiab winding nws mus rau hauv ib zaj duab xis. Kev ua haujlwm tau zoo yog qhov tseem ceeb rau cov nqi tsim khoom thiab cov khoom zoo kawg. Txawm li cas los xij, ntau qhov kev sib tw tuaj yeem tshwm sim thaum lub sijhawm tsim khoom, xws li kev sib txhuam siab ntawm cov khaubncaws sab nraud povtseg thiab cov yeeb yaj kiab thaiv, uas tuaj yeem txo qhov ua tau zoo thiab cuam tshuam cov khoom zoo.
Kab lus no yuav tshawb txog cov txheej txheem ntawm PE tshuab zaj duab xis, tsom mus rau aua tau zoo plam thiab anti-blocking additivethiab yuav ua li cas nws pab kov yeej cov kev cov nyom ntau lawm kom ua kom tag nrho kev ua tau zoo thiab txhim kho kev ua yeeb yaj kiab.
PE Blown Film Production Technical Overview and Efficiency Factors
Txheej txheem cej luam ntawm Blown Film Extrusion txheej txheem
Lub tshuab cua tshuab extrusion txheej txheem pib nrog kev pub mis ntawm PE resin pellets rau hauv ib qho extruder, uas lawv tau yaj thiab homogenized los ntawm kev sib xyaw ua ke ntawm cov cua sov thiab shear rog. Tom qab ntawd cov molten polymer raug yuam los ntawm lub voj voog tuag, tsim ib lub raj txuas ntxiv. Cua yog nkag mus rau hauv nruab nrab ntawm lub raj no, inflating nws mus rau hauv ib tug npuas. Cov npuas no yog ces kos upwards, ib txhij stretching zaj duab xis nyob rau hauv ob qho tib si lub tshuab kev taw qhia (MD) thiab transverse direction (TD), ib tug txheej txheem hu ua biaxial orientation. Raws li cov npuas ascends, nws yog txias los ntawm lub nplhaib cua, ua rau cov polymer crystallize thiab solidify. Thaum kawg, cov npuas dej txias tau tawg los ntawm ib txheej ntawm cov nip rollers thiab raug mob rau hauv ib lub yob. Qhov tseem ceeb tsis cuam tshuam rau cov txheej txheem suav nrog yaj kub, qhov sib txawv tuag, qhov sib piv (BUR), frost line qhov siab (FLH), thiab qhov cua txias.
Tej yam tseem ceeb cuam tshuam rau kev tsim khoom
Ntau yam cuam tshuam ncaj qha rau kev ua haujlwm ntawm PE tshuab zaj duab xis ntau lawm:
• Kev Tshaj Tawm: Tus nqi ntawm cov yeeb yaj kiab raug tsim tawm. Higher throughput feem ntau txhais tau tias muaj kev ua tau zoo dua.
• Zaj duab xis zoo: Qhov no suav nrog cov khoom xws li thickness uniformity, mechanical zog (tensile zog, kua muag tsis kam, dart impact), optical zog (xua, gloss), thiab nto yam ntxwv (coefficient ntawm kev sib txhuam). Cov yeeb yaj kiab tsis zoo ua rau cov khoom seem nce ntxiv thiab txo kev ua haujlwm.
• Lub sij hawm poob: Tsis npaj nres vim muaj teeb meem xws li zaj duab xis tawg, tuag tsim, lossis khoom siv tsis raug. Kev txo qis qis yog qhov tseem ceeb rau kev ua haujlwm.
• Kev siv hluav taws xob: Lub zog yuav tsum tau ua kom yaj cov polymer, ua haujlwm ntawm extruder, thiab lub zog cua txias. Txo kev siv hluav taws xob txhim kho kev ua haujlwm tag nrho thiab txo cov nqi ua haujlwm.
• Kev Siv Cov Khoom Siv Raw: Siv PE resin thiab cov khoom ntxiv kom zoo, txo cov khoom pov tseg.
Common PE Blown Film Production Challenges
Txawm hais tias muaj kev vam meej hauv kev siv tshuab, PE tshuab zaj duab xis ntau lawm ntsib ntau yam teeb meem uas tuaj yeem cuam tshuam kev ua haujlwm:
• Kev thaiv zaj duab xis: Qhov tsis xav tau adhesion ntawm cov khaubncaws sab nraud povtseg ntawm zaj duab xis, tsis hais nyob rau hauv yob los yog thaum ua cov kauj ruam tom ntej. Qhov no tuaj yeem ua rau muaj teeb meem hauv kev ua kom tsis muaj zog, nce cov khoom seem, thiab kev tsim khoom qeeb.
• High Coefficient of Friction (COF): Kev sib txhuam siab ntawm cov yeeb yaj kiab tuaj yeem ua rau muaj teeb meem thaum lub sij hawm winding, unwinding, thiab converting kev khiav hauj lwm, ua rau sticking, tearing, thiab txo cov txheej txheem ceev.
• Tuag Build-up: Cov khoom ntawm cov polymer degraded los yog additives nyob ib ncig ntawm qhov tuag tawm, ua rau streaks, gels, thiab films tsis xws luag.
• Melt Fracture: Irregularities ntawm zaj duab xis nto tshwm sim los ntawm siab shear stress nyob rau hauv lub tuag, ua rau ib tug ntxhib los yog wavy tsos.
• Gels thiab Fisheyes: Undispersed polymer hais los yog cov kab mob uas tshwm sim me me, pob tshab los yog opaque defects nyob rau hauv zaj duab xis.
Cov kev cov nyom no feem ntau yuav tsum tau ua kom qeeb ntawm cov kab ntau lawm, nce cov khoom pov tseg, thiab yuav tsum tau muaj kev cuam tshuam tus neeg siv ntau dua, tag nrho cov no txo qis kev ua haujlwm tag nrho. Kev siv tswv yim ntawm cov khoom siv ntxiv, tshwj xeeb tshaj yog cov nplaum nplaum thiab cov tshuaj tiv thaiv thaiv, ua lub luag haujlwm tseem ceeb hauv kev txo cov teeb meem no thiab ua kom cov txheej txheem ntau lawm.
Cov txheej txheem rau kev kov yeej cov teeb meem hauv kev tsim cov yeeb yaj kiab yas
