I-galvanized wire coating ilukhuni, ifilimu ye-passivation ayikhanyi, izinga lokushisa lokugeza liphezulu kakhulu.Uma ukuminyana kwamanje kwe-cathode kuphezulu kakhulu, okuqukethwe kwe-zinc kubhavu kuphezulu kakhulu noma i-sodium hydroxide kanye nokuqukethwe kwe-DPE kuphansi kakhulu;Isixazululo se-Electroplating esinezinhlayiya eziqinile noma ukungcola okweqile kwensimbi yangaphandle, kuzoholela ezinkingeni ezinjalo.Isixazululo: Uma i-roll enkulu eyakhiwe ngocingo eya kulena engenhla ilukhuni, kungase kube nezinhlayiya eziqinile kusixazululo sokucwenga.Uma ukuqina kwengxenye bukhulu, ukuminyana kwamanje kungase kube phezulu kakhulu.
Uma i-zinc inamathela kahle, kodwa lapho ukukhanya kuphuma ku-3% nitric acid, kunethunzi elimnyama embotsheni, futhi ifilimu iba nsundu uma kwenzeka i-passivation, okungenzeka kubangelwe ukungcola kwensimbi yangaphandle njengethusi noma umthofu. oketshezini lukathayela.Uma kunenkinga ohlelweni lwe-galvanizing, hlola izinga lokushisa kanye nokuminyana kwamanje kuqala, bese ulinganisa futhi ulungise okuqukethwe kwe-zinc ne-sodium hydroxide okugeza ngokusebenzisa ukuhlaziywa kokugeza.Ukuthi amazinga e-DPE aphansi yini kunganqunywa ukuhlolwa kweseli ye-Hull.
Uma ukuqina kokumboza kungabangelwa yizizathu ezingenhla, kungase kubangelwe ukungcola esixazululweni se-plating.Ingathatha inani elincane lesisombululo se-electroplating, ngemva kokuhlolwa kokuhlunga, bese ithatha inani elincane lesisombululo se-electroplating, ngemva kokuhlolwa kokwelashwa kwe-zinc powder, hlola ukuthi inkinga ibangelwa izinhlayiya eziqinile noma ithusi, umthofu nokunye ukungcola kwensimbi yangaphandle.Zihlole ngayinye ngayinye futhi akunzima ukuthola imbangela yenkinga.Insimbi eyakhanyiswa ngensimbi enamathelayo igwebu, amandla okubopha awalungile.
Ukwelashwa okungalungile ngaphambi kwe-electroplating;Izinga lokushisa lokugeza liphansi kakhulu;Izithasiselo zekhwalithi ephansi noma izithasiselo ezidlulele kanye nokungcola okuphilayo kungabangela ukuhlangana okubi.Izinga le-additive libuye libe nomthelela ekufakeni amagwebu.Ezinye izithasiselo zisabela ngendlela engaphelele ngesikhathi sokuhlanganiswa futhi ziyaqhubeka nokwenza i-polymerize phakathi nokugcinwa noma ukusetshenziswa kwesikhathi eside.I-additive ijwayele ukuhlanekezela i-lattice futhi idale ukucindezeleka, okubangela ukunamathela ku-blister.
Lapho roll enkulu lashukumisa wire galvanizing inqubo enamathela ogwebu, hlola kuqala lokushisa okugeza.Uma izinga lokushisa lokugeza lingekho phansi, qinisa i-plating ngaphambi kokukhipha uwoyela, vimbela insimbi ye-matrix ekugqwaleni kwe-asidi.Uma unaka lezi zinkinga, isenzakalo esinamagwebu sisekhona, kufanele sinake inani kanye nekhwalithi yezithasiselo, khona-ke ungakwazi ukuyeka ukwengeza izithasiselo, nge-electrolysis ephezulu yamanje isikhathi esithile, ukuze unciphise okuqukethwe izithasiselo, bheka ukuthi lesi simo esinamagwebu siyathuthukiswa yini.Uma kungakabi khona ukuthuthukiswa, kuyadingeka ukuhlola ukuthi isikhathi sokugcina sezithasiselo side kakhulu, noma ngabe kukhona ukungcola okuningi kakhulu ezithasiselweni.
