Electroplating pretreatment ndiyo hwaro hwe electroplating uye kiyi yekuve nechokwadi chemhando yewaya inopisa.Kana iyo substrate isina kubatwa kune zvakatarwa zvinodiwa pamberi pe electroplating, kunyangwe ine yakanaka electroplating mhinduro, yakakodzera electroplating parameters uye midziyo yekudzora electroplating parameters, pamwe nevashandi vane hunyanzvi, hazvibviri kuwana iyo electroplating coating inosangana nemhando zvinodiwa.
Asati plating hakusi chete kubvisa simbi matrix, uye kuvapo kwemafuta uye kukanganisa coating adhesion uye zvimwe zvinodiwa zvemhando yechinhu chekunze, vanodawo kubvisa pamusoro oxide, ita kuti ayo ane yakataurwa utsanana uye pamusoro basa, kuona kuti coating. uye iyo substrate yakasimba ne, maererano nezvinodiwa zvekuonekwa kwekuputira, dzimwe nguva ichaita mamwe maitiro anokosha asati aputira.
Mamiriro ebasa uye hupenyu hwesevhisi yesimbi ye electrogalvanized kana zvikamu zvine hukama nehupamhi hweplating.Kunyanya kuomarara kwemamiriro ekushandisa uye kureba kwehupenyu hwesevhisi, kukora kunodiwa galvanizing layer inofanira kuve.Zvigadzirwa zvakasiyana, zvinoenderana nemamiriro ekunze (tembiricha, humidity, kunaya kwemvura, kuumbwa kwemuchadenga, nezvimwewo) kuona hupenyu hunotarisirwa hwesevhisi yekukora kwemagetsi, kukora kwemapofu kuchakonzera marara akasiyana.Asi kana ukobvu husina kukwana, hahuzosangana nezvinodiwa zvehupenyu hwesevhisi zvinotarisirwa.
Vagadziri vakasiyana, zvinoenderana nemamiriro avo emidziyo, kana iri yekutarisa rudzi rweplating, tanga waunganidza yakawedzera uye inonzwisisika nzira yekuyerera, yakajeka plating paramita, kudzora plating mhinduro yekuisa, yakajairwa kushanda.Post-plating kurapwa nechinangwa chekusimudzira dziviriro, kushongedza uye zvimwe zvakakosha zvinangwa zveplating zvikamu.Mushuregalvanizing, chromate passivation, kana kumwe kutendeuka kurapwa kunowanzo kudiwa kuti ugadzire inoenderana mhando yekushandura firimu, inova imwe yeakakosha maitiro ekuona kunaka kweiyo plating.
