I-alkaline zinc nickel alloy brightener BZ-617 iyi-alkaline zinc nickel alloy electroplating inqubo eklanyelwe ukuhlangabezana nezidingo zemakethe zokuqukethwe kwe-nickel alloy kufika ku-16%. Le alloy electroplated inganikeza ukubukeka okuhle kakhulu ukumelana nokugqwala kanye nokubekezelela ukwelashwa kokushisa kwangemva kokudlula. Inganikeza uhla oluphelele lwezingubo zokumboza, okuhlanganisa: ukugqama kombala, okuluhlaza okwesibhakabhaka, okugqamile okumhlophe nokufiphala okumnyama.
Ingxubevange ye-zinc-nickel 51017 enobungani bemvelo iyinqubo ye-alkaline ye-zinc-nickel alloy electroplating, eklanyelwe ukuhlangabezana nesidingo semakethe esifinyelela ku-16% wokuqukethwe kwe-nickel alloy.
I-Zn-323 ingakhiqiza ungqimba lwe-passivation eluhlaza okwesibhakabhaka olunokumelana nokugqwala okuhle kakhulu kwe-zinc-nickel alloy coatings enokuqukethwe kwe-nickel kuka-12-15%. Ngenqubo yokucwilisa elula, ungqimba olufanayo lwe-blue passivation lungakhiqizwa ngamandla amahle okubopha. Ukwelashwa kokuvala kungathuthukisa ukumelana nokugqwala futhi kwenze ukubukeka kwe-coating kushintshe kumbala wensimbi engenasici.
ingakha ungqimba lwe-passivation eluhlaza okwesibhakabhaka olunokumelana nokugqwala okuhle kakhulu kwe-zinc-nickel alloy coatings enokuqukethwe kwe-nickel okungu-12-15%. Ngenqubo yokucwilisa elula, ungqimba olufanayo lwe-blue passivation lungakhiqizwa ngamandla amahle okubopha. Ukwelashwa kokuvala kungathuthukisa ukumelana nokugqwala futhi kwenze ukubukeka kwe-coating kushintshe kumbala wesiliva - insimbi engagqwali.
I-Zn-324 iyifilimu enemibala egqamile ye-chromium passivation ye-electroplating zinc-nickel alloy workpieces. Le nqubo ingakhiqiza ifilimu ekhanyayo, enombala okhanyayo (umbala ophakathi kophuzi noluhlaza), futhi inokumelana nokugqwala okuphezulu. Ngefilimu yosiko ye-chromium ene-hexavalent enemibala eminingi, lokhu kwelashwa kunikeza abasebenzisi ukukhetha okuphephile. Ingasetshenziswa ekulengeni nasekugingqeni izinhlelo zokusebenza zenqubo.
inqubo ye-chromium enemibala emithathu ye-electroplating zinc-nickel alloy workpieces. Le nqubo ingase iveze ukukhanya okuluhlaza , umbala okhanyayo ( umlamuli wombala ophuzi noluhlaza phakathi ) kwefilimu, futhi inokumelana nokugqwala okuphezulu.
I-Zn-325 ifanele i-trivalent chromium isiliva-white passivation ye-zinc-nickel alloys, enokumelana nokugqwala okuhle <br> Ilungele ukudluliswa kongqimba lwe-alkaline noma lwe-asidi ye-zinc-nickel, kokubili ukucwenga kwe-rack kanye nokufakwa kwemiphongolo. Isendlalelo sokudlula esigqamile esiwumphumela simelana nezinga lokushisa eliphezulu futhi singasekela ihora elilodwa ku-120℃.
ifanele i-trivalent chromium white passivation ye-zinc-nickel alloys, enokumelana nokugqwala okuhle. Kokubili i-rack plating kanye ne-barrel plating kuyatholakala. Isendlalelo se-passivation esimhlophe esiphumayo sinomphumela omuhle kakhulu wokulwa nokugqwala ngisho nangemva kokwelashwa kokushisa ku-120 ℃ amahora angama-24.
I-Zn-327 ikhiqiza ungqimba olumnyama lokuhlobisa lokudlula olunokumelana nokugqwala okuphezulu ku-zinc-nickel alloy coating enokuqukethwe kwe-nickel okungu-12-18% ngenqubo yokucwilisa elula. Ifanele i-rack plating kanye ne-barrel plating, ngokubekezelela okuphezulu ukungcola kwe-zinc.
i-zinc-nickel alloy trivalent chromium black passivation agent ikhiqiza ungqimba olumnyama lokuhlobisa olunokugqwala okuphezulu kwentokozo ye-zinc-nickel alloy enokuqukethwe kwe-nickel okungu-12-18% ngenqubo yokucwilisa elula .
