Amakhoyili amakhulu weucingo lukathayelakwakhiwa ngomdwebo wocingo, umdwebo wocingo uwuhlobo lobuchwepheshe bokucubungula, ungenza umkhiqizo ufinyelele isimo esidingekayo futhi uhlangabezane nezakhiwo ezijwayelekile zemishini.Umdwebo obandayo udwetshwa ekushiseni kwe-recrystallization, umdwebo oshisayo udonswa ekushiseni kwe-crystallization, umdwebo ofudumele udwetshwa ekamelweni lokushisa elingaphezulu kodwa ngaphansi kwezinga lokushisa le-crystallization.Umdwebo obandayo uyindlela evamile yokudweba.Umdwebo oshisayo ukushisisa kwentambo yensimbi ngaphambi kokuthi ingene embotsheni yokufa.Ngokuyinhloko isetshenziselwa ukudweba ucingo lwensimbi olunephuzu eliphakeme lokuncibilika.
Umdwebo ofudumele kufanele ushiswe yi-heater kububanzi obushiwo bezinga lokushisa, ikakhulukazi elisetshenziselwa ama-galvanized, okunzima ukuguqulwa komdwebo wezintambo zensimbi.Intambo eyisithakoicutshungulwa ngenqubo yokudweba, ukwakheka kokucaciswa okujwayelekile kocingo lwensimbi, bese kuba sethangini le-electroplating ngokusebenzisa indawo yamanje yokucwenga i-zinc unidirectional.Ijubane lokukhiqiza lihamba kancane, ungqimba lwe-zinc lwe-zinc plating lufana kakhulu, ukushuba kuncane kakhulu, ngokuvamile kuma-microns angu-3 ~ 15, ukukhanya kuphezulu kakhulu, kodwa ukumelana nokugqwala okuphansi, uma uyisebenzisa kunconywa ukuthenga ngokuvumelana. ekufuneni.
Amakhoyili amakhulu weucingo lukathayelaimikhiqizo isetshenziswa kabanzi ngenxa yokugqwala kwayo nokumelana nokugqwala, ngoba i-zinc inomphumela omkhulu wokuvikela ekubukeni komkhiqizo, ngakho-ke ithuthukisa kakhulu indima nezici zomkhiqizo ngokwawo, obuye ukhuthaze ukukhuthazwa kokusetshenziswa komkhiqizo.Ungqimba lwezinc locingo lwezinc olunogqinsi lwezinc lunobucwebe obuhle, umfaniswano futhi alinagebe, kanye nokungagqwali okuhle.
Ingqimba ye-zinc etholwe nge-electrogalvanizing imsulwa kakhulu futhi igqwala kancane kugesi, uketshezi kanye nenkungu ye-asidi ne-alkali, engavikela ngempumelelo isisekelo sensimbi.Isendlalelo esiphehliwe singaba futhi ukwelashwa kwe-chromic acid passivation sibe imibala ehlukahlukene, enhle futhi ephanayo, inokuhlobisa okuhle.Ungqimba lwezinc ocingweni olunothayela lune-ductility enhle, lungaba ukunyathela okubandayo, ukugoqa, ukugoba nokunye okwakhayo ngaphandle kokulimala kongqimba lwezinc.
