1. Lub brkister ntawv ci rau cov menyuam yaus uas tau txais cov qauv sib xyaw ntawm cov ntawv, polyester zaj duab xis thiab txhuas ntawv ci, uas zoo nce lub zog ntawm cov yeeb yaj kiab sib xyaw. Lub thickness ntawm polyester zaj duab xis yog tswj hwm rau 12-35um, thiab cov tawv thiab sib npaug tsis kam yog qhov zoo heev. Cov khoom siv capping yuav siv cov tshuaj, Thiab lub zog ntawm kev qhib yog 7-20 N / 15 hli, uas tuaj yeem tiv thaiv cov menyuam yaus los ntawm qhib lub pob thiab kev noj cov tshuaj los ntawm qhov yuam kev, Thiab paub txog kev nyab xeeb ntawm cov menyuam noj tshuaj;

2) Cov me nyuam lub txim nyiaj ci yog ua los ntawm cov ntawv sib xyaw, polyester zaj duab xis thiab txhuas ntawv ci. Thaum txhim kho lub zog ntawm cov yeeb yaj kiab sib xyaw, Daim ntawv kuj tseem siv tau los ua cov cab kuj rau cov ntawv luam, substrates thiab cov duab kos kom nce ruaj ruaj ntawm zaj duab xis. Tiv thaiv cov menyuam yaus los ntawm kev rhuav tshem cov yeeb yaj kiab sib xyaw, txhim kho kev nyab xeeb ntawm kev siv, Qhov teeb ntawm txhuas ntawv ci tuaj yeem txuas ntxiv block dej vapor thiab oxygen, thiab qhov teeb tsa ntawm varnish yog yooj yim los tiv thaiv cov nyhuv ntawm number case thiab ntawv, Nce qhov chaw khau khiab dhau ntawm cov khoom, thiab cov cua sov sealing txheej. Nws yog ib qho yooj yim kom ua kom sov li cua sov nrog lub hlwv thiab muaj cov nyhuv sib khi;

3) Cov txheej txheem cua sov-Sealing txheej yog tsim los ua los ntawm vc kua nplaum nrog kev noj tshuaj ntawm 3.5-4.5 g / m2. Nws yog kev ua tau zoo kub-Sealing cov kua nplaum ntawm thermoplastic hluavtaws rov qab. Nws yog ib qho kev sib tiv thaiv kev nyab xeeb thiab ib puag ncig cov mis tsis muaj Halogen hlaws cov ntsiab lus. Qhov zoo ntawm cov kua muag tsis tshua muaj zog thiab ntuag ntuag;

4) Ob tus txheej txheem sib xyaw ua ke yog saws, and three step temperature change methods are adopted in each compounding process, which improves the appearance effect of the compounded film, enhances the compounding fastness, and improves the easy tearing property.
