Cov qauv kuaj ua ntej-coated films feem ntau suav nrog ob pawg tseem ceeb: cov khoom siv raw (substrate, txheej) thiab cov khoom tiav (txheej txheej). Cov khoom tseem ceeb ntawm kev soj ntsuam zoo muaj xws li zaj duab xis thickness, adhesion, corrosion resistance, abrasion resistance, thiab thermal stability.
Cov cuab yeej kuaj pom muaj xws li zaj duab xis thickness gauges, lub tshuab ntsuas tensile, ntsev tsuag tshuaj xeb kuaj chambers, kev sib txhuam thiab hnav testers, thiab cov ntsuas kub distortion. Cov qauv kev lag luam ntsig txog suav nrog Suav Lub Teeb Kev Lag Luam Txuj Ci QB/T 2889-2007 Biaxially Oriented Polypropylene (BOPP) Pre-coated Zaj duab xis, uas qhia meej cov ntsiab lus, kev faib tawm, kev xav tau, kev sim, thiab kev soj ntsuam cov cai rau BOPP pre-coated films.
Kev sim cov txheej txheem ua ntej -coated films feem ntau yog tsom rau lub cev, tshuaj, thiab cov khoom nto ntawm txheej zaj duab xis kom ntseeg tau tias nws zoo thiab kev ntseeg tau. Feem ntau siv cov cuab yeej ntsuas lub cev muaj xws li kev ntsuas qhov tuab ntawm zaj duab xis, kev kuaj adhesion, thiab kev ua kom yooj yim thiab kev ntsuas qhov cuam tshuam. Zaj duab xis thickness tuaj yeem ntsuas tau siv cov txheej thickness gauge lossis microscopic sectioning los xyuas kom meej txheej txheej. Adhesion feem ntau raug soj ntsuam siv tus ntoo khaub lig- txiav kev sim lossis rub- tawm kev xeem los ntsuas qhov sib txuas ntawm cov txheej txheem thiab cov txheej txheem substrate. Flexibility thiab cuam tshuam tsis kam raug txheeb xyuas los ntawm kev khoov, folding, lossis kev sim pob los txiav txim siab seb cov yeeb yaj kiab puas tuaj yeem tawg lossis tev thaum ua haujlwm lossis siv.
Cov khoom siv tshuaj lom neeg thiab kev ntsuas huab cua tiv thaiv yog qhov tseem ceeb sib npaug. Kev tiv thaiv corrosion tuaj yeem raug soj ntsuam los ntawm kev ntsuam xyuas ntsev los yog cov kua qaub / alkali kev daws teeb meem rau kev ntsuam xyuas cov yeeb yaj kiab kev tiv thaiv hauv cov av ntub lossis tshuaj lom neeg. Huab cua tiv thaiv tuaj yeem raug kuaj los ntawm kev laus zuj zus los yog UV irradiation txhawm rau txhawm rau txhawm rau fading, chalking, lossis embrittlement. Tsis tas li ntawd, kev ntsuam xyuas kev ua haujlwm saum npoo suav nrog cov ntsuas xws li gloss, smoothness, thiab xim sib xws, uas cuam tshuam ncaj qha rau cov yeeb yaj kiab zoo nkauj thiab zoo nkauj. Los ntawm cov txheej txheem kev sim, qhov ua tau zoo ntawm qib ua ntej-coated zaj duab xis tuaj yeem raug soj ntsuam zoo, muab lub hauv paus txhim khu kev qha rau kev tsim khoom, kev lees paub, thiab kev siv ua haujlwm.
