I-Hot-dip galvanizing, isezingeni lokushisa eliphezulu i-zinc ingots iyancibilika, ibekwe ezintweni ezisizayo, khona-ke isakhiwo sensimbi sicwiliswa endaweni yokugeza ye-zinc, ukuze ilungu lensimbi linamathele ungqimba ongqimbeni lwezinc.Inzuzo eshisayo yama-galvanized incike ekhonweni layo lokulondoloza, ngcono ukunamathela kanye nobulukhuni bongqimba olunama-galvanized.

I-Cold galvanizing iyisisombululo sikasawoti we-zinc nge-electrolysis, ekufakweni kwe-coating, ngokuvamile, engenakho ukufudumeza, inani le-zinc elingavamile ukubhekana nemvelo enomswakama kulula kakhulu ukuwa.Amakhaza galvanizing ukwelashwa ngokomzimba, nje ebusweni shayela ungqimba zinc, zinc enamathela kulula ukuwa off ukusetshenziswa hot-dip ukwakhiwa lashukumisa.

Inqubo ye-hot-dip galvanizing kanye ne-galvanizing ebandayo

Idiphu elishisayo eliphehliwe ligxiliswa ku-zinc ewuketshezi encibilikisiwe workpiece degreasing, pickling, dipping, omiswe isikhathi esithile futhi ubeke phambili.

I-Cold galvanizing, ebizwa nangokuthi i-electro-galvanized, iwukusetshenziswa kwedivaysi ye-electrolysis endaweni yokusebenza ekubunjweni kwesisombululo sikasawoti we-zinc, ngemva kokukhipha amafutha, ukuqoqa, nokuxhuma i-electrode engalungile yedivayisi ye-electrolytic;ipuleti le-zinc elibekwe ngakolunye uhlangothi lwe-workpiece lixhunywe kudivayisi ye-electrolytic i-electrode eqondile, amandla avuliwe, i-current esuka ku-electrode eyakhayo iye ekuhambeni okuqondisayo okungekuhle, izofakwa endaweni yokusebenza ngongqimba lwezinc. .

Ukubukeka kwe-hot-dip galvanizing kanye ne-galvanizing ebandayo

Cold galvanizing kubukeka bushelelezi ngaphezulu, egqamile, umbala passivation inqubo Plating ungqimba inombala ophuzi-luhlaza, kwaba ezimibalabala.Isendlalelo sokucwenga sasimhlophe-luhlaza noma simhlophe sinenqubo emhlophe yokudlula sasiluhlaza, inqubo yokwemboza emhlophe futhi ilanga laliyi-engeli Enemibala ebalulekile.Ingxenye eyinkimbinkimbi yamaphethelo angama-angular ethambekele "ekushisweni kukagesi" kusuka kumnyama, izingxenye zongqimba lwezinc.Isayithi lekhona le-Yin lilula ukwenza indawo empunga yamanje efile futhi ungqimba lwezinki lwendawo luzacile.I-workpiece iyonke i-zinc tumor, i-caking phenomenon.

Idiphu elishisayo eliphehliwe libukeka limaholoholo uma liqhathaniswa ne-electro-galvanized, silvery white, bheka imigqa yamanzi yenqubo ethambekele kanye namaconsi ambalwa esimila kusobala kakhulu, ikakhulukazi engxenyeni eyodwa yokusebenza.Isendlalelo se-zinc dip esishisayo esinezinsimbi kunezikhathi ezimbalwa zokuvikela ukugqwala okuwugqinsi kwe-electro-galvanized siphindwe kaningana kunokwe-electro-galvanized.
