Kev tsim cov yeeb yaj kiab yeeb yaj kiab feem ntau yog siv cov cam co-extrusion technology, siv linear low-density polyethylene (LLDPE) raws li cov khoom siv hauv paus, ntxiv los ntawm cov nqi tsim nyog ntawm cov xim masterbatch thiab cov khoom siv ntxiv rau cov xim tshwj xeeb. Ua ntej kev tsim khoom, cov khoom siv raw tau raug kev faib ua feem thiab sib xyaw ua ke kom ntseeg tau tias qhov sib txawv ntawm cov khoom ntxiv; qhov no tsim cov khoom siv ruaj khov rau kev ua haujlwm tom ntej thaum lav cov xim zoo ib yam thiab kev ua haujlwm ruaj khov.
Cov khoom sib xyaw ua ke yog pub rau hauv ib qho extruder, qhov chaw uas lawv tau rhuab thiab yaj ntawm qhov kub thiab txias los ua ib homogeneous, plasticized yaj. Cov yaj no yog extruded tusyees los ntawm ib tug precision tuag thiab nkag mus rau ib tug cam khwb cia- txias system rau sai shaping. Kev ua kom txias sai sai ua kom cov yeeb yaj kiab ua kom pom tseeb, tiaj tus, thiab cov khoom siv kho tshuab- ua kom muaj zog stretchability zoo, toughness, thiab puncture resistance-thaum ua kom cov xim sib txawv thiab txo cov xim sib txawv.
Cov yeeb yaj kiab tsim tau dhau los ua cov kauj ruam tom ntej, suav nrog kev thauj mus los - tawm, hauv - kab thickness ntsuas, ntug trim recycling, thiab tsis siv neeg winding. Thoob plaws hauv kev tsim khoom, tsis muaj xws li cov yeeb yaj kiab thickness, qhov dav, tensile zog, thiab qhov zoo ntawm qhov chaw raug saib xyuas thiab kho hauv lub sijhawm tiag tiag - kom ua raws li cov kev qhia tshwj xeeb. Rau cov khoom uas xav tau tus kheej siab -adhesion, cov txheej txheem tswj los yog tshwj xeeb additives yog ua hauj lwm los txhim kho kev sib raug zoo ntawm cov zaj duab xis txheej.
Tom qab winding, cov xim stretch zaj duab xis tau kuaj pom, ntsuas qhov ntev, ntsuas qhov hnyav, thiab ntim khoom; tsuas yog cov khoom ua tau raws li cov qauv zoo tau pom zoo rau kev khaws khoom lossis xa khoom xa tuaj. Cov kab ntau lawm niaj hnub no feem ntau siv cov txheej txheem tswj tsis tau tsuas yog ua kom muaj txiaj ntsig zoo xwb tab sis kuj ua kom cov khoom zoo sib xws, xa cov khoom siv txhim khu kev qha, siab -kev ua tau zoo xim stretch zaj duab xis rau kev siv hauv logistics, warehousing, thiab industrial ntim.
