Ingagwenywa kanjani imibimbi ebangelwa ukuphulukiswa kwefilimu?
Imibimbi ebusweni befilimu ingenzeka ngesikhathi somiswa nokuphulukiswa kwefilimu. Ngokuvamile kunezinhlobo ezintathu zokushwabana: imibimbi eyenzeka ngesikhathi kufakwa ifilimu okokuqala, imibimbi yobuhlalu eyenzeka lapho kufakwa ifilimu ngokuphindaphindiwe, kanye nemibimbi ebangelwa isenzo samagesi ane-asidi ngaphakathi kuhhavini.
Uhlobo lokuqala lwemibimbi lungenzeka kakhulu uma kusetshenziswa i-epoxy resin-based coatings. Ngenxa yomphumela we-catalytic wamagesi ane-acidic kuhhavini, ingaphezulu lefilimu liphulukisa ngokushesha, okuholela ekucindezelekeni kwangaphakathi, imibimbi yokuncipha, eyaziwa nangokuthi imifantu yomoya noma imibimbi yekristalu.
Uhlobo lwesibili lwemibimbi lungenzeka uma usebenzisa i-alkyd resin coatings, i-coatings equkethe ama-conjugated double bond, noma lapho kusetshenziswa ama-agent okomisa ngokweqile. Uma amazinga e-oxidation kanye ne-polymerization ebusweni nangaphakathi befilimu engaguquki, ukucindezelwa okuhlukile kungaholela ekushwabaneni.
Uhlobo lwesithathu lwemibimbi lungenzeka uma usebenzisa ngokuphindaphindiwe i-alkyd resin coatings noma i-styrene-alkyd resin coatings. Lokhu kungenxa yokuthi izimbotshana ezixhumene ngokuphambanayo ziphinde zifakwe ngaphambi kokufinyelela ukuminyana kwazo okugcwele kokuxhumanisa, okubangela ukuthi izincibilikisi ezisembozweni zande futhi zidale imibimbi.
Ukuze uvimbele ngempumelelo uhlobo lokuqala lwemibimbi, ungagwema ukufafaza ifilimu kakhulu. Kufanele futhi unake ekunqumeni okunengqondo izingxenye ze-ejenti yokwelapha ukuze wenze ubuso nangaphakathi kwefilimu yokugqoka yome ngokulinganayo.
Ukuze uvimbele uhlobo lwesibili lwemibimbi, kuyadingeka ukugwema ukusebenzisa ama-solvents ane-solubility eqinile endaweni ehlanganiswe phezulu bese uzama ukusebenzisa ama-solvents abuthakathaka ngokushintshashintsha okusheshayo. Lapho uphinda umboza, igebe elithile lokumboza lidinga ukugcinwa, futhi ungqimba olungaphezulu lungafafazwa kuphela ngemva kokuba ungqimba olungezansi selapheke ngokugcwele.
