Izinga lokushisa Eliphansi Lokwelapha Impushana Yezinto Ezingaphansi Ezizwela Ukushisa

Ukwelapha Kwezinga Lokushisa Eliphansi Amakhava wePowder Okwama-Substrates angezwani nokushisa

Ukuze isetshenziswe kuma-substrates angezwani nokushisa njenge-MDF, impushana kufanele yelaphe ngaphansi kuka-302°F (150°C) noma ngisho no-212°F (100°C). Isikhombisaral Kuye kwasungulwa izindlela zokufeza lo mgomo, kusukela kumakhemikhali avamile asebenzisa izinga lokushisa eliphansi kuya kumakhemikhali aguquguqukayo alapheka ngemisebe.

Inani elikhulu lama-athikili ashicilelwe kanye namalungelo obunikazi aqinisekise ikhono lobuchwepheshe obulapheka nge-UV ukukhiqiza izimbotshana ezicwebezelayo, ezibushelelezi ku-MDF phakathi nemizuzu emithathu kuya kwemihlanu yesikhathi sokucubungula.8Izinzuzo eziyinhloko zezimpushana ezilashwe yi-UV zihlanganisa ukukhiqiza okuphezulu nokonga kwendawo ngenxa izikhathi ezimfushane zokuphulukisa emazingeni okushisa aphansi, ukuphela okuhle kakhulu kwendawo kanye nezakhiwo zefilimu, ingozi encishisiwe yokulimala kwe-MDF ngenxa yokwehla kwezinga lokushisa eliphakeme futhi, okubaluleke kakhulu, ukuzwela okuncishisiwe ekukhipheni umoya. Kodwa-ke, ubuchwepheshe be-UV bubuye bube nezithiyo eziningi, okuhlanganisa ukungakwazi ukukhiqiza ukunamathela okuqinile noma okuluhlaza, ukucaciswa komthunzi (ikakhulukazi ama-shades aphuzi), ukungazinzi esimweni sezulu esishisayo, izindleko zempahla ephezulu kanye nezidingo eziphezulu zempahla yemali. Amasistimu e-UV abuye aveze ubunzima bokucubungula ngesikhathi sokukhishwa okujwayelekile ngenxa yezinga lokushisa eliphansi lokushintsha kwengilazi. Le mikhawulo ivimbe ukuthengiswa okukhulu kwalobu buchwepheshe.

Uma kuqhathaniswa, izimpushana ezijwayelekile zokwelapha ezishisayo azinayo imikhawulo emithunzini, ukuqedwa komphumela, ukujiya koqweqwe, ukuzinza komkhiqizo esimweni sezulu esifudumele, ubujamo bezinto, njll., futhi zingashintshwa ukuze kusetshenziswe izinto ezivamile zokukhipha kanye nemishini yokufaka isicelo. Okuwukuphela komphumela wabo izinga lokushisa eliphakeme lokuphulukisa. Ngenxa yalesi sizathu, indlela ekahle yokuqinisekisa ukwamukeleka okusekelwe okubanzi kungaba ukuthuthukisa ubuchwepheshe obufanele bokushisa obuphansi obuyimpushana bokumboza kumakhemikhali akhona e-thermal-cure.

Ekubuyekezeni umsebenzi wocwaningo owenziwe ngama-powders anciphisa izinga lokushisa, izinhlelo ezisebenzisa i-glycidyl methacrylic (GMA) acrylics - ingxube ye-amorphous ne-crystalline epoxy kanye nezinhlelo ze-polyester resin, kanye nama-catalysts afanelekile okwelapha - abe yimpumelelo kakhulu. Ama-GMA acrylics ahlinzeka ngesimo sezulu esihle kakhulu, ukubukeka kwefilimu, ukucaca kwefilimu kanye umbala ukugcinwa, kanye nokungabikho kwemikhiqizo ngesikhathi sokwelashwa kanye nezinga lokushisa eliphansi lokuphulukisa. Ukusetshenziswa kwezohwebo kwalezi zindlela zobuchwepheshe zokwelapha izinga lokushisa eliphansi sekwenziwe ngehora lesikhombisaral izitshalo zezimoto, kuhlanganise ne-General Izimoto, i-BMW kanye ne-Chrysler, nezinye eziningi zisemkhathizwe maduze ukuze zihambisane nemithetho eqinile yokukhipha umoya.
