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 osungunuka a utomoni wopangira filimu wa utoto wokutidwa ndi bolodi ndi gawo lapansi losankhidwa moyenerera, lipanga kusanjikiza kosanjikiza pakati pa gulu lopaka utoto wopaka utoto ndi filimu yokutira, Izi ndizofunikira pakumatira kwabwino kwa zokutira.
Kuyanika kwa Bgulu TACHIMATA bolodizokutira
Kumanga kumamatira kwa utoto wokutira bolodi wokutira kumangomaliza gawo loyamba la ❖ kuyanika filimu mapangidwe mu ❖ kuyanika ❖ kuyanika bolodi ❖ kuyanika, 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 kuphulika kwa zosungunulira kapena zofalitsa zina zobalalitsira mu filimu 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, ndi zina zambiri. Komabe, zokutira zamakono zambiri sizimapanga mafilimu m'njira imodzi, koma zimadalira njira zingapo kuti potsirizira pake zipange mafilimu, ndipo zokutira koyilo ndi mtundu wamba wa filimu. zomwe zimadalira njira zingapo pomaliza kupanga mafilimu.
