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;Izinhlayiya eziqinile noma ukungcola kwensimbi yangaphandle ngokweqile kusixazululo se-electroplating kungabangela izinkinga ezinjalo.Isixazululo: Uma enamathela of ezinkuluucingo lukathayelailukhuni, kungase kube nezinhlayiya eziqinile ekhambi le-plating.Uma ukuqina kwengxenye bukhulu, ukuminyana kwamanje kungase kube phezulu kakhulu.
Uma i-zinc enamathela kuhle, kodwa ku-3% ye-nitric acid lapho ukukhanya, i-coating inethunzi elimnyama, i-passivation ivela lapho ifilimu insundu, ingase ibangelwe ukungcola kwensimbi yangaphandle njengethusi noma umthofu oketshezini oluvuthayo.Lapho izinkinga zenzeka ohlelweni lokugaya ikhoyili enkuluucingo lukathayela, izinga lokushisa kanye nokuminyana kwamanje kuhlolwa kuqala, bese okuqukethwe kwe-zinc ne-sodium hydroxide kusisombululo sokucwenga kuyalinganiswa futhi kulungiswe ngokuhlaziywa kwesisombululo se-plating.Ukuthi okuqukethwe kwe-DPE kuphansi yini kunganqunywa ngokuhlolwa kwe-hull cell.
Uma ukuqina kokumboza kungabangelwa yizizathu ezingenhla, kungase kubangelwe ukungcola esixazululweni se-plating.Ingathatha inani elincane lesisombululo se-electroplating, ukuhlolwa kokuhlunga, bese ithatha inani elincane lesisombululo se-electroplating, ngokwelashwa kwe-zinc powder ngemva kokuhlolwa, hlola inkinga izinhlayiya eziqinile noma ithusi, umthofu nokunye ukungcola kwensimbi yangaphandle okubangelwa.Ngamunye, akunzima ukuthola imbangela yenkinga.I-galvanized iron wirei-blister enamathela, ukunamathela okubi.
Ukwelashwa okungalungile ngaphambi kokucwenga;Izinga lokushisa lokugeza liphansi kakhulu;Ikhwalithi engeyinhle yezithasiselo noma izithasiselo eziningi kakhulu nokungcola okuphilayo kuzodala ukuhlangana okubi.Izinga lezithasiselo libuye libe nomthelela ekufakeni amagwebu.Ezinye izithasiselo zisabela ngendlela engaphelele ngesikhathi sokuhlanganiswa futhi ziyaqhubeka nokwenza i-polymerize phakathi nokugcinwa noma ukusetshenziswa kwesikhathi eside.Isengezo sivame ukuhlanekezela i-crystal lattice futhi sibangele ingcindezi, okubangela ukuthi ukunamathela kubhamuze.
Lapho enamathela of ezinkuluucingo lukathayelaI-blistered in the process of galvanizing, izinga lokushisa lokugeza kufanele lihlolwe kuqala.Uma izinga lokushisa lokugeza lingekho phansi, bese uqinisa ukususwa kwamafutha ngaphambi kokucwenga, ukuvimbela isisekelo sensimbi ekugqwaleni kwe-asidi.Uma unaka lezi zinkinga, umkhuba wokubhubhudla usekhona, kufanele unake umthamo kanye nekhwalithi yezithasiselo, khona-ke ungakwazi ukuyeka ukungeza izithasiselo, nge-electrolysis ephezulu yamanje isikhathi esithile, ukunciphisa okuqukethwe kwezithasiselo, bheka ukuthi ukwenzeka kwebhamuza kuyathuthukiswa yini.Uma kungekho ukuthuthukiswa, hlola ukuthi ingabe isithasiselo sigcinwe isikhathi eside noma siqukethe ukungcola okuningi kakhulu.
