Ukukhuselwa kwe-zinc coating kwi-matrix yensimbi kunemigaqo emibini: kwelinye icala, nangona i-zinc isebenza ngakumbi kwaye ilula i-oxidize kunentsimbi, kodwa ifilimu yayo ye-oxide ayikhululekile kwaye ihlangene njenge-iron oxide.Umaleko oshinyeneyo owenziwe phezu komphezulu unqanda i-oxidation eyongezelelweyo ye-zinc ngaphakathi.Ngokukodwa emva kokupasa kwe-galvanized layer, umphezulu we-oxide layer unzima kwaye uxinene, ngokwawo unokukhusela okuphezulu kwe-oxidation.
Kwelinye icala, xa umphezulu weyenziwe igalatiumaleko wonakele, uveza i-matrix yentsimbi yangaphakathi, kuba i-zinc isebenza ngakumbi kunentsimbi, ngeli xesha, i-zinc ithwala indima yokubingelela i-zinc anode, i-zinc iya kuba ne-oxidized phambi kwentsimbi, ukwenzela ukukhusela i-iron layer ayiyi konakala.
I-Orchard ekhethekileyo yocingo lwenkqubo ye-electroplating ibubushushu besisombululo se-zinc ukuntywiliselwa, isantya semveliso, ukutyabeka okutyebileyo kodwa okungalinganiyo, imarike ivumela ukutyeba oku-1 okuphantsi kweemicrons ezingama-45, ukuya kuthi ga kuma-300 eemicrons.Imnyama ngombala, itya isinyithi se-zinc ngakumbi, kwaye ibumba kumaleko kunye nesiseko sesinyithi, kwaye inokumelana ne-corrosion elungileyo.Idiphu eshushu ye-galvanizing inokuqhubeka amashumi eminyaka kwindawo yangaphandle.
Orchard inkqubo ekhethekileyo electroplating ngocingo olukhanyayo mhlophe,ucingo lwezinkiukuthunyelwa kwindawo eyomileyo nengena umoya, ayinakuthunyelwa kwindawo emanzi.Ucingo lwegalvanized alunakudityaniswa kunye nezinto ze-asidi kunye ne-alkaline ukunqanda ukusabela kweekhemikhali kunye nokuhlwa kocingo oluyizinki.Ucingo lwegalvanized kufuneka lubekwe mcaba, ukunqanda uhlaselo lwe-zigzag.
