Kuthunyelwe ku 2018-08-13Umgomo wokwelashwa kwe-Dacromet surface ukuhlukanisa ukusebenzisana phakathi kwamanzi, umoya-mpilo nensimbi ukuze uthole umphumela oqinile we-antiseptic.Umgomo ngokuyinhloko ukubambisana kwezindlela ezintathu zokuvikela.
Umthelela ovimbelayo: Izendlalelo ze-zinc ezintekenteke ne-aluminium ku-coating zigqagqana endaweni engaphezulu yensimbi ukuze zakhe isendlalelo sokuqala esivikelayo, esivimbela indawo ebolayo efana namanzi nomoya-mpilo ukuthi ixhumane ne-substrate, edlala umphumela wokuzihlukanisa oqondile kakhulu.
I-Passivation: Enkambisweni yokwelashwa kwe-chromic acid nge-zinc, i-aluminium powder kanye ne-base metal Dacromet, ifilimu ye-passivation eyakhiwe phezu kwamakhemikhali, ifilimu ye-passivation ayithambekele ekuphenduleni ukugqwala, futhi isebenza njengesithiyo.Isenzo semidiya eyonakalisayo, kanye nomthelela wokuvinjelwa, sihlinzeka ngokuvikela okuyizendlalelo ezimbili okuqinisa imiphumela yokuhlukaniswa ngokomzimba.
Ukuvikelwa kwe-Cathodic: Lona umphumela wokuvikela obaluleke kakhulu.Njengomthetho wongqimba olunamanzi, ukuvikelwa kwe-cathodic kusetshenziswa ku-substrate kungqimba lwamakhemikhali ngokunikela nge-anode.
Ngakolunye uhlangothi, lezi zinhlobo ezintathu zokuvikela zivikela umthelela ogqwalayo wezinto ezibolayo kunsimbi.Ngakolunye uhlangothi, i-substrate igqwalile ngogesi, futhi akumangalisi ukuthi kunezikhathi eziningana umphumela wokuvikela we-zinc yendabuko ye-electroplating.
