Ubwino wachuma wogwiritsa ntchito mapepala oponyera kupanga zikopa zopangira ndi zikopa zopangira ndi izi:
Mtengo wa 1.Zida zimachepetsedwa kwambiri.Izi zili choncho chifukwa njira yopangira zitsulo pogwiritsa ntchito mapepala oponyera ndi yosavuta kusiyana ndi njira yokutira ndi njira ya calendering yazitsulo zosapanga dzimbiri potengera zipangizo.Kuphatikiza apo, pepala lotulutsa ndi lotsika mtengo kwambiri kuposa tepi yachitsulo chosapanga dzimbiri.
2.Pepala loponyera lingagwiritsidwe ntchito mobwerezabwereza.M'mayiko akunja, angagwiritsidwe ntchito mobwerezabwereza kwa 5 nthawi kupanga PVC yokumba zikopa ndi nthawi 10 kupanga polyurethane kupanga chikopa.Zoonadi, kuchuluka kwa kugwiritsidwa ntchito mobwerezabwereza kumakhala ndi ubale wofunikira kwambiri ndi zipangizo zopangira, kusungirako ndi mlingo wa ntchito za opanga zikopa zopangira.
3.Ikhoza kusintha pamwamba pa chikopa chopanga kapena chikopa chopangidwa, zomwe sizingatheke kuchita ndi lamba wosapanga dzimbiri.Zomwe zimatchedwa "kusintha kwapamwamba" kumatanthauza kuti pepala lomasulidwa losindikizidwa limatha kusamutsa mitundu yosiyanasiyana ya zikopa pamwamba pa chikopa chopanga kapena chikopa chopangidwa, ndipo chikhoza kusintha pamwamba.Kuphatikiza apo, imatha kupangitsa kuti pamwamba pakhale zonyezimira zosiyanasiyana, kuyambira matt, semi gloss mpaka gloss yokwera kwambiri.Komanso, ndizosavuta kusintha njere zachikopa, osasintha zida zilizonse, ingosinthani pepala lotulutsa ndi njere zachikopa zofunika.
4. Zimalepheretsa kumamatira kwa chikopa chopanga kapena chikopa chopangidwa.Pepala lotulutsa limakutidwa ndi polyvinyl chloride kapena viniga wa polyurethane.Akaumitsa, amatha kukulungidwa kuti asungidwe ndikusenda pakafunika.Izi ndizosatheka ndi zonyamulira zina.
5.Multilayer zokutira akhoza kuchitidwa pa pepala lomasulidwa lomwelo.
6.Pachikopa chochita kupanga kapena chikopa chopangidwa ndi mitundu yosiyanasiyana ya utomoni, mawonekedwe a peeling a pepala lomasulidwa akhoza kusinthidwa ndikuwongoleredwa.
Njira zazikuluzikulu zamagawo a pepala lotulutsa zikopa ndi izi:
A. Malinga ndi gulu la glossiness, likhoza kugawidwa mu mtundu wowunikira, mtundu wowala, mtundu wowala kwambiri, mtundu wa kutha kwa theka, mtundu wa kutha ndi mtundu wapamwamba kwambiri;
B. Malinga ndi ❖ kuyanika zakuthupi, zikhoza kugawidwa mu silicon ofotokoza pepala ndi sanali pakachitsulo zochokera pepala;
C.Ikhoza kugawidwa mu polyvinyl kolorayidi (PVC) yokumba chikopa pepala ndi polyurethane chikopa pepala malinga ndi gulu ntchito;
D. Itha kugawidwa m'mapepala osavuta komanso mapepala ojambulidwa malinga ndi mikwingwirima kapena ayi.
