Ikhasimende libuze ukuthi ngesikhathi kusetshenziswa i-zinc ingxubevange ye-nickel i-passivator emnyama, ukudluliswa kwe-workpiece kwalandelwa ukuvala uphawu, futhi ukuvela kwefilimu ye-passivation kuzofakwa umbala.I-workpiece imnyama ngokufanayo futhi igqamile ngaphambili, ingafakwa kanjani umbala?
Ngokolwazi lwasensimini kanye nezici zomkhiqizo zinc nickel alloy black passivator Zn-327, i-Bigolly Technology ihlaziye ukuthi ifilimu edlulayo ye-workpiece inombala ikakhulukazi ngenxa yezizathu ezintathu ezilandelayo:
1. Ukugxiliswa kwe-brightener kuphezulu noma ukugxila kwesengezo se-nickel kuphansi ngesikhathi soplating we-zinc nickel alloy electroplating.Lapho ukugxiliswa kokukhanya kusixazululo sokucwenga kuphezulu kakhulu, ukubukeka kwe-coating kuba kukhanya kakhulu, futhi ukubukeka kuzoba nombala lapho kwenziwa ukudlula okumnyama; Uma ukugxila kwesengezo se-nickel kuphansi kakhulu, okuqukethwe kwe-nickel ekwembathweni kuzoba kuphansi, futhi ifilimu ye-passivation izoba lula ukufakwa umbala ngesikhathi sokukhanya okumnyama. .Ngakho-ke, enqubweni yokukhiqiza, ukugxila kokugqamayo kanye nesithasiselo se-nickel esixazululweni sokucwenga kungalungiswa ngaphakathi kwebanga lenqubo ngokuhlolwa kweseli ye-Hull.
2. Ngemva kokuphasisa okumnyama kocezu lokusebenza, ifilimu yokudlulisa izofakwa umbala. Ngalesi sikhathi, hlola ukuthi ingabe i-coefficient yokusebenza yesixazululo sokudlula ilungile yini. Uma ukugxilwa kwesisombululo se-passivation siphansi kakhulu noma inani le-pH liphezulu kakhulu, ifilimu ye-passivation izoba nombala.Ngakho-ke, kuyadingeka ukuqinisekisa ukuthi imingcele yokusebenza yesisombululo sokudlulisa ingaphakathi kwebanga lenqubo ngesikhathi senqubo yokukhiqiza.
3. Ukugxila okuphansi kwe-ejenti yokuvala noma isikhathi esifushane sokuvalwa kuzoholela efilimini encane futhi engalingani yokuvala ye-workpiece, okulula ukubonakala i-brittle ngemva kokoma.Iyunifomu kanye nefilimu yokuvala egcwele ingaqinisekiswa ngokukhula. ukugcwala kwe-ejenti yokuvala noma ukusebenzisa izindlela zokwelapha ezimbili zokuvala, okuwukuthi inqubo yokomisa okomisa uphawu.
Ngakho-ke, kufanele sinake la maphuzu amathathu lapho ifilimu ye-workpiece passivation inombala ngesikhathi kusetshenziswa zinc nickel alloy black passivator, futhi sixazulule ukwehluleka ngokushesha ngangokunokwenzeka ukunciphisa ukulahlekelwa.Uma uthanda zinc nickel alloy black passivator, sicela uthinte Bigolly customer service ukuze uthole amasampula amahhala nolwazi oluningiliziwe lobuchwepheshe!
Uma ufuna ukwazi okwengeziwe nge-zinc nickel alloy, ungachofoza ukuze ubuke "Electroplating encyclopedia".
