Kupanga filimu yagulu TACHIMATA bolodizokutira makamaka zikuphatikizapo mbali ziwiri: ❖ kuyanika adhesion ndi kuyanika kuyanika.
Kumamatira kwa A color coated board coating
Gawo loyamba pakumatira pakati pa gawo lapansi lachitsulo ndi zokutira ndikunyowetsa utoto wokutira bolodi pamtunda wapansi panthaka.The ❖ kuyanika wetting akhoza m'malo mpweya ndi madzi poyamba adsorbed pa zitsulo Mzere gawo lapansi pamwamba.Pa nthawi yomweyo, volatilization wa zosungunulira pamwamba pa gawo lapansi kumabweretsa kuvunda kapena kutupa.Ngati magawo solubility a filimu kupanga utomoni wa mtundu TACHIMATA bolodi ❖ kuyanika ndi gawo lapansi pamwamba amasankhidwa moyenerera, izo kupanga immiscible wosanjikiza pakati pa mtundu TACHIMATA bolodi gawo lapansi pamwamba ndi ❖ kuyanika filimu, Izi n'zofunika kuti bwino adhesion wa ❖ kuyanika.
Kuyanika kwa Bgulu TACHIMATA bolodizokutira
Kumanga zomata za utoto wokutira bolodi ❖ kuyanika kumangomaliza sitepe yoyamba ya ❖ kuyanika filimu mapangidwe mu ndondomeko ❖ kuyanika mtundu TACHIMATA bolodi, ndi ndondomeko kukhala olimba mosalekeza filimu ayenera kupitiriza, amene akhoza kumaliza lonse ❖ kuyanika filimu mapangidwe ndondomeko.Njira yosinthira kuchokera ku "filimu yonyowa" kupita ku "filimu yowuma" nthawi zambiri imatchedwa "kuyanika" kapena "kuchiritsa".Kuyanika ndi kuchiritsa uku ndiko maziko a filimu yophimba kupanga.Zovala zokhala ndi mawonekedwe osiyanasiyana ndi zolemba zimakhala ndi njira zawo zopangira filimu, zomwe zimatsimikiziridwa ndi zinthu zomwe zimagwiritsidwa ntchito popanga filimuyo.Nthawi zambiri, timagawaniza njira yopangira mafilimu m'magulu awiri:
(1) Zosasintha.Kawirikawiri, amatanthauza njira yopangira mafilimu, yomwe makamaka imadalira kutentha kwa zosungunulira kapena zofalitsa zina zobalalitsira mufilimu yophimba, pang'onopang'ono kuwonjezera kukhuthala kwa filimu yophimba ndikupanga filimu yophimba yolimba.Mwachitsanzo, zokutira za acrylic, zokutira mphira wa chlorinated, zokutira za ethylene, etc.
(2) Kusintha.Nthawi zambiri, zimatanthawuza kuchitika kwa kusintha kwa mankhwala panthawi yopanga filimu, ndipo zokutira zimadalira kwambiri kusintha kwa mankhwala kuti apange filimu.Kupanga filimuyi kumatanthawuza ku polymerization ya zinthu zopanga mafilimu mu zokutira, zomwe zimatchedwa ma polima, pambuyo pa ntchito.Tinganene kuti njira yapadera ya kaphatikizidwe polima, amene kwathunthu amatsatira zimene limagwirira wa polima kaphatikizidwe.Mwachitsanzo, zokutira za alkyd, zokutira za epoxy, zokutira za polyurethane, zokutira za phenolic, etc. Komabe, zokutira zamakono zambiri sizimapanga mafilimu m'njira imodzi, koma zimadalira njira zingapo kuti potsirizira pake zipange mafilimu, ndipo zophimba za koyilo ndi mtundu wamtundu wa filimu womwe umadalira njira zambiri kuti potsirizira pake apange mafilimu.
