Kev tuav lub substrate kom huv si yog qhov tseem ceeb tshaj plaws rau kev siv pre-coated films. Ua ntej daim ntawv thov, tshem tawm cov plua plav, roj, thiab dej kom huv si kom tsis txhob cuam tshuam cov txheej txheej adhesion thiab du nto. Thaum tuav thiab txhim kho, tsis txhob khawb cov zaj duab xis nto nrog cov khoom ntse thiab txo qis khoov lossis ncab kom tsis txhob tawg lossis tawg. Rau cov nplooj ntawv loj, nws raug nquahu kom ntau tus neeg ua haujlwm ua ke kom ntseeg tau tias cov yeeb yaj kiab tseem nyob ruaj khov thaum thauj.
Kev txiav thiab kev ua tiav yog qhov tseem ceeb ntawm kev siv cov yeeb yaj kiab ua ntej -coated. Cov cuab yeej txiav yuav tsum tau ceev ceev, thiab txiav ceev yuav tsum yog nruab nrab los tiv thaiv tev lossis burrs ntawm cov npoo zaj duab xis. Stamping, dabtsi yog khoov, thiab lwm yam kev khiav hauj lwm yuav tsum tau kho nyob rau hauv lub quab yuam thiab lub kaum sab xis raws li lub thickness thiab yooj ntawm cov zaj duab xis kom tsis txhob ntev stretching los yog compression. Thaum lub sij hawm ua, yog tias raug kub los yog tshuaj lom neeg tshaj tawm, kev sib cais lossis kev tiv thaiv yuav tsum tau ua kom ntseeg tau tias cov txheej txheem txheej tsis cuam tshuam.
Kev khaws cia thiab kev tiv thaiv kuj cuam tshuam rau kev ua tau zoo ntawm pre-coated films. Cov yeeb yaj kiab uas tsis siv ua ntej -coated yuav tsum tau muab dov los yog muab tso rau hauv qhov chaw qhuav, qhov cua, tsis txhob tshav ntuj ncaj qha thiab ya raws, thiab khaws cia kom deb ntawm cov kua qaub, alkalis, thiab lwm yam tshuaj. Rau cov yeeb yaj kiab uas twb tau txuas nrog cov substrates, kev sib txhuam ntev ntev los yog raug rau qhov kub thiab txias yuav tsum tau zam kom ntau li ntau tau kom muaj qhov ci ntsa iab thiab kev tiv thaiv. Los ntawm kev ua haujlwm thiab kev tswj xyuas kom zoo, lub neej ua haujlwm ntawm cov yeeb yaj kiab ua ntej -coated films tuaj yeem txuas ntxiv tau zoo, ua kom muaj kev tiv thaiv zoo thiab zoo nkauj hauv kev lag luam xws li kev tsim kho, khoom siv hauv tsev, thiab kev thauj mus los.
