1. Ukulawulwa kwenqubo ye-Electroplating
Isimo sesevisi kanye nempilo yesevisi yeucingo lwensimbinoma izingxenye zihlobene eduze nobukhulu bokunamathela.Uma izimo zokusebenzisa ziqinile futhi isikhathi eside nempilo yesevisi, ungqimba oludingekayo locingo lwensimbi kufanele lube lushubile.Imikhiqizo ehlukene, ngokuya ngendawo ethize (izinga lokushisa, umswakama, imvula, ukwakheka komkhathi, njll.) ukuze kunqunywe impilo yesevisi elindelekile yobukhulu bokugquma, ukujiya okuyimpumputhe kuzodala zonke izinhlobo zemfucuza.Kodwa uma ukushuba kunganele, ngeke kufinyelele izidingo zempilo yesevisi elindelekile.Abakhiqizi abahlukene, ngokwezimo zabo zemishini, uma kunqunywa ukucwenga, ukulungiswa kokuqala kokugeleza kwenqubo ephelele futhi enengqondo, imingcele ecacile yokucwenga, ukulawula ukugxila kwesixazululo se-plating, ukusebenza okujwayelekile.
2, i-hot plating wire Plating ngemuva kokucubungula
Ukwelashwa kwe-post-plating (i-passivation, ukuncibilika okushisayo, ukufaka uphawu nokususwa kwe-hydrogen, njll.) ngenjongo yokuthuthukisa izakhiwo zokuzivikela, umhlobiso nezinye izinjongo ezikhethekile.Ngemuva kokufakwa kukaphethiloli, i-chromate passivation noma okunye ukwelashwa kokuguqulwa ngokuvamile kuyadingeka ukuze kwakhiwe uhlobo oluhambisanayo lwefilimu yokuguqula, okungenye yezinqubo eziyinhloko zokuqinisekisa ikhwalithi ye-post-plating.
3, ngocingo lukathayela inqubo
Ezingxenyeni ezibalulekile nezibalulekile ezinamandla amakhulu kuno-1034Mpa, ingcindezi kufanele isuswe ku-200 ± 10 ℃ isikhathi esingaphezu kwehora elingu-1 ngaphambi kokucwenga, kanye nezingxenye eziqinile noma eziqinile, ingcindezi kufanele isuswe ku-140 ± 10 ℃ ukuze uthole okwengeziwe. amahora angaphezu kwama-5.I-ejenti yokuhlanza esetshenziselwa ukuhlanza ngeke ibe nomthelela emandleni okubopha we-coating futhi akukho ukugqwala ku-substrate.Ukwenza kusebenze i-Acid Isixazululo sokwenza kusebenze i-asidi kufanele sikwazi ukususa imikhiqizo egqwalile nefilimu ye-oxide (isikhumba) phezu kwezingxenye ngaphandle kokugqwala okukhulu ku-matrix.
Ukugalela kungenziwa nge-zincate galvanizing noma nge-chloride galvanizing.Izithasiselo ezifanele kufanele zisetshenziselwe ukuthola i-coating ehlangabezana nezidingo zaleli zinga.Ukwelashwa okukhanyayo kufanele kwenziwe ngemuva kokufakwa okukhanyayo.Izingxenye ezidinga ukukhishwa i-dehydrogenation ukuze i-passivation kufanele idluliswe ngemva kokukhishwa kwe-hydrogen.Ngaphambi kokudlula, i-1% H2SO4 noma i-1% ye-hydrochloric acid kufanele ifakwe ukuze isebenze i-5 ~ 15s.I-passivation izophathwa nge-chromate enemibala ngaphandle uma kucaciswe ngenye indlela emidwebeni yokuklama.
Ukusetshenziswa okubanzi kocingo lukathayela kulethe ukunethezeka okukhulu ekukhiqizeni nasekuphileni kwabantu, kodwa inqubo yokukhiqizwa kocingo lwensimbi nayo akufanele ithathwe kancane.Emkhiqizweni wezimboni, inqubo yokukhiqiza yocingo oluvunyiwe kufanele ilawulwe ngokuqinile ukuze kuqinisekiswe ikhwalithi yocingo oluvunyiwe.
