Iyo yekudzivirira yenguva yemarara yakatsetseka yemupumburu mukurugalvanized wireinowirirana zvakanyanya nehupamhi hwekuputira.Kazhinji kutaura, mugasi rakakura rakaoma uye kushandiswa kwemukati, uye mumamiriro ezvinhu akaomarara, ukobvu hwemalata hunofanira kunge hwakanyanya.Naizvozvo, kukanganisa kwezvakatipoteredza kunofanirwa kutariswa pakusarudza ukobvu hwemagalvanized layer.Mushure mekurapwa kwepassivation kweyakagadzikwa, musara weyakajeka yekare uye yakanaka ruvara passivation firimu inogona kugadzirwa, iyo inogona zvakanyanya kuvandudza mashandiro ayo ekudzivirira.
Kune akawanda marudzi emarara mhinduro, inogona kukamurwa kuita cyanide plating mhinduro uye cyanide plating mhinduro.Cyanide galvanizing solution ine kupararira kwakanaka uye kugona kuvhara, kupfekedza crystallization kwakatsetseka uye kwakanaka, kushanda kuri nyore, kureba kwekushandisa, kwakashandiswa mukugadzira kwenguva yakareba.Nekudaro, nekuti iyo plating mhinduro ine yakanyanya muchetura cyanide, iyo gasi inobuda muplating process inokuvadza kuhutano hwevashandi, uye mvura yemarara inofanirwa kunyatsogadziriswa isati yaburitswa.
Zinc isimbi-chena simbi, brittle pakamuri tembiricha, soluble mu acid uye alkali, inozivikanwa seamphoteric simbi.Zinc yakachena inogadzikana zvakanyanya mumhepo yakaoma, uye idiki mumhepo ine hunyoro kana mvura ine carbon dioxide uye oxygen.Firimu rakaonda rezinc carbonate richaumbwa pamusoro, izvo zvinogona kunonoka kukora kwe zinc layer.Kudzivirirwa kwekuora kwemarara mumhinduro ine aqueous yeasidhi, alkali uye sodium chloride ine simba.Izvo zvakare haidzivirirwe nekuora mumhepo ine carbon dioxide uye hydrogen sulfide uye muMarine atmospheres;Mutembiricha yakakwira uye mumhepo yakanyanyisa uye ine organic acid atmosphere idiki, galvanized layer zvakare iri nyore kuita ngura.
