Kapangidwe (Zida)
Zikwama Zosinthika, Matumba & Mafilimu a Rollstock
Mapangidwe osinthika amapangidwa ndi laminated ndi mafilimu osiyanasiyana, cholinga chake ndi kupereka chitetezo chabwino cha zomwe zili mkati kuchokera ku zotsatira za okosijeni, chinyezi, kuwala, kununkhira kapena kuphatikiza kwa izi.Kwa zinthu zomwe zimagwiritsidwa ntchito nthawi zambiri zimasiyana ndi wosanjikiza wakunja, wosanjikiza wapakati, wosanjikiza wamkati, inki ndi zomatira.
1. Kunja:
Chosanjikiza chakunja chosindikizira nthawi zambiri chimapangidwa ndi mphamvu yabwino yamakina, kukana kwamafuta abwino, kukwanira bwino kusindikiza komanso magwiridwe antchito abwino.Zomwe zimagwiritsidwa ntchito kwambiri pakusindikiza ndi BOPET, BOPA, BOPP ndi zida zina zamapepala.
Zofunikira zakunja kwa layer zili ngati izi:
| Zinthu zowunika | Kachitidwe |
| Mphamvu zamakina | Kukana kukoka, kukana misozi, kukana kwamphamvu komanso kukana kukangana |
| Chotchinga | Cholepheretsa mpweya ndi chinyezi, kununkhira, ndi chitetezo cha UV. |
| Kukhazikika | Kukana kuwala, kukana mafuta, kukana kwa zinthu za organic, kukana kutentha, kukana kuzizira |
| Kugwira ntchito | Friction coefficient, thermal contraction curl |
| Chitetezo chaumoyo | Nontoxic, kuwala kapena fungo kuchepetsa |
| Ena | Kuwala, kuwonekera, chotchinga kuwala, kuyera, ndi kusindikizidwa |
2. Pakatikati
Zomwe zimagwiritsidwa ntchito kwambiri pakati ndi Al (filimu ya aluminiyamu), VMCPP, VMPET, KBOPP, KPET, KOPA ndi EVOH ndi zina. Pakati ndi zotchinga CO.2, Oxygen, ndi Nayitrogeni kuti adutse phukusi lamkati.
| Zinthu zowunika | Kachitidwe |
| Mphamvu zamakina | Kukoka, kukangana, kung'ambika, kukana mphamvu |
| Chotchinga | Chotchinga madzi, gasi ndi fungo |
| Kugwira ntchito | Ikhoza kupangidwa ndi laminated m'malo onse awiri apakati |
| Ena | Pewani kuwala kudutsa. |
3. Wosanjikiza wamkati
Chofunika kwambiri kwa wosanjikiza wamkati ndi mphamvu yabwino yosindikiza.CPP ndi PE ndizodziwika kwambiri kugwiritsa ntchito ndi wosanjikiza wamkati.
| Zinthu zowunika | Kachitidwe |
| Mphamvu zamakina | Kukana kukoka, kukana misozi, kukana kwamphamvu komanso kukana kukangana |
| Chotchinga | Khalani ndi fungo labwino komanso ndi adsorption |
| Kukhazikika | Kukana kuwala, kukana mafuta, kukana kwa zinthu za organic, kukana kutentha, kukana kuzizira |
| Kugwira ntchito | Friction coefficient, thermal contraction curl |
| Chitetezo chaumoyo | Nontoxic, kuchepetsa fungo |
| Ena | Transparency, yosatheka. |
