Ihluke kanjani i-Fusion Bonded Epoxy kupende
I-Fusion bonded epoxy kanye nopende kubukeka kufana eshadini lemibala kodwa kuziphatha ngendlela ehluke ngokuphelele epaneleni lensimbi. I-FBE iyi-powder efakwa nge-electrostatic encibilikayo futhi ivuthwe ku-200–230 °C ibe ifilimu eqhubekayo engu-180–280 µm ubukhulu, enikeza isibopho se-anchor-to-substrate esingafinyelelwa upende we-solvent ngokunamathela kuphela. Ikhonjiswe ku-AWWA C550 ngomphumela we-salt spray odlula amahora angu-4000. Upende ufakwa uwuketshezi ezingeni lokushisa lendawo ngefilimu encane, i-solvent eningi, kanye nesikhathi esifushane kakhulu ngaphambi kokuvela kwe-holiday yokuqala.
Ukufaniswa ngokuvamile kuqala emhlanganweni wesicaciso njengombuzo wezindleko: umugqa we-epoxy eyimpushana uma uqhathaniswa nomugqa we-coating ependiwe. Kufanele kuqale njengombuzo wokusebenza, ngoba lezi zinto ezimbili zehluleka ngezindlela ezihlukene futhi umehluko unquma ukuthi isitshalo sizolungisa kangakanani i-coating eminyakeni eyishumi. Unjiniyela oke wabona i-tank lining ependiwe iqhumuka emgqeni wamanzi uyazi ukuthi ifilimu yayingakaze inamathele ensimbi; lowo oke wahlola iqokobhe eline-epoxy uyazi ukuthi ifilimu iyinsimbi. Ukuqonda ukuthi kungani le miphumela emibili yenzeka yikho okuningi kwesicaciso, futhi kuyisisekelo sendlela i-fusion bonded epoxy ehluke ngayo kupende. Lowo mehluko kufanele ube sesicacisweni njengesigatshana sezinto, hhayi ukushiyelwa eshadini lemibala.
I-Chemistry Yokusebenzisa: Ukuncibilika nokwelapha kuqhathaniswa nokuhwamuka kwe-solvent
Okunye kuyisenzakalo sokuhlangana okushisayo, okunye kuyisenzakalo sokomisa. I-epoxy ehlanganiswe ngokushisa ifakwa njengempuphu eyomile ngesifutho sikagesi phezu kwendawo elungisiwe futhi eshisiselwe ezingeni lokuvuthwa, ngokuvamile u-200–230 °C; impuphu iyancibilika, igeleze futhi ihlangane ibe ifilimu eqhubekayo emanzi insimbi futhi ebambelela esakhiweni sengaphansi. Upende uwuketshezi oluphethe i-resin ku-solvent, olufakwa ngebhulashi, i-roller noma isifutho esingenamoya ezingeni lokushisa eliseduze noma elijwayelekile, kwakheka ifilimu njengoba i-solvent ihwamuka; ifilimu ihlala phezu kwensimbi futhi ihlala inamathele kuphela uma kungena lutho ngaphansi kwayo. Lowo mehluko owodwa uchaza cishe konke ukuziphatha okulandelayo: ifilimu ehlanganisiwe ayikwazi ukuncibilika kabusha nge-solvent, kuyilapho ifilimu ependwe ingakwazi, futhi ifilimu ehlanganisiwe ayincikile ekunamatheleni njengendlela yayo eyinhloko.
Ukujiya kwefilimu nokwakheka kulandela lokho. I-FBE icaciswa ebangeni lika-180–280 µm ngokujiya okukalwa njengomphumela osebenzayo wokusetshenziswa okukodwa nokuphulukiswa okuchaziwe, yingakho ukuhlolwa kwenziwa nge-wet-film ne-dry-film gauge esikhundleni sokulinganisa ukumboza. Uhlelo lukapende olujwayelekile lwakhiwa ngezingqimba eziningi, ngayinye incane, futhi ukujiya kwefilimu eyomile isiyonke ngokuvamile kuba ngaphansi futhi kuncike ekutheni umsebenzisi wayeqaphela kangakanani. Lapho ukucaciswa kudinga umgoqo oqinile owodwa, ifilimu ye-epoxy ifinyelela lapho ngokuhamba okukodwa; lapho ukucaciswa kudinga umbala, ukumelana namakhemikhali nokubekezelela emaphethelweni, upende unerekhodi elide elisunguliwe ezakhiweni zangaphandle.
