1149 Barrel Bright Nickel Plating
kufotokozera kwa malonda
▪ Njirayi ikuwonetsa mphamvu yoponya bwino kwambiri, kuonetsetsa kuti madziwo aikidwa mofanana ngakhale m'ma geometri ovuta komanso m'malo ozama. Kukhazikika kwa bafa kumasungidwa kwa nthawi yayitali, ndi kuwonongeka kochepa kwa zowonjezera zachilengedwe, zomwe zimathandiza kuti plating ikhale yabwino nthawi zonse. Kapangidwe ka electrolyte kamakhala ndi zowunikira zapadera ndi zinthu zoyezera zomwe zimawonjezera mphamvu yoponya ya micro-, zomwe zimapangitsa kuti pamwamba pake pakhale posalala komanso powala.
▪ Njirayi imagwirizana ndi ma rack ndi ma plating a migolo, zomwe zimapangitsa kuti pakhale kusinthasintha pogwira ntchito zosiyanasiyana za workpiece ndi ma volumes. Bafa limagwira ntchito bwino mkati mwa kutentha kwakukulu, nthawi zambiri pakati pa 45°C mpaka 65°C, komwe kumatha kusinthidwa kutengera zofunikira zinazake. Mlingo wa pH umayendetsedwa mosamala mkati mwa mtunda wopapatiza, nthawi zambiri pakati pa 3.8 mpaka 4.5, kuti muwongolere kuchuluka kwa ma depositi ndi mawonekedwe a kupaka.
▪ Kuchuluka kwa ma ioni a nickel mu plating solution kumakhala mkati mwa 70 mpaka 90 g/L, pomwe ma ioni a chloride amasungidwa pakati pa 10 mpaka 20 g/L kuti atsimikizire kuti anode ikuwonongeka bwino komanso kuti ikuyenda bwino. Kugwiritsa ntchito ma anodi a nickel oyeretsedwa kwambiri, kuphatikiza ndi matumba a anode, kumachepetsa kulowetsedwa kwa zinyalala ndi tinthu tating'onoting'ono m'bafa.
▪ Njirayi imagwiritsa ntchito njira zamakono zosefera, zomwe nthawi zambiri zimagwiritsa ntchito makatiriji oyeretsera a ma micron 5 mpaka 10, kuchotsa zinthu zolimba zomwe zayimitsidwa ndikusunga kuyera bwino kwa bafa. Kuyesa kwa Hull cell kumachitika nthawi zonse kuti muwone momwe bafa limagwirira ntchito ndikusintha kuchuluka kwa zowonjezera ngati pakufunika. Kusinthasintha kwa nickel layer yoyikidwa nthawi zambiri kumapitirira 8%, monga momwe zimayesedwera ndi mayeso a spiral contractometer, kuonetsetsa kuti magwiridwe antchito abwino kwambiri pa ntchito zopanga pambuyo pa plating.
▪ Kulimba kwa chophimbacho kungasinthidwe pakati pa 250 mpaka 450 HV mwa kusintha magawo osambira ndi ma ratio owonjezera, zomwe zimapangitsa kuti chikhale choyenera kugwiritsidwa ntchito m'mafakitale osiyanasiyana. Njirayi ikuwonetsa makhalidwe abwino kwambiri omatirira, ndipo mayeso a mphamvu ya peel nthawi zonse amapitilira 8 N/mm². Kukana dzimbiri kwa nickel deposit, monga momwe amayesedwera ndi mayeso a salt spray, nthawi zambiri kumapitirira maola 96 ku dzimbiri loyera ndi maola 200 ku dzimbiri lofiira likatsekedwa bwino.
▪ Mphamvu yayikulu yoponyera macro-throw ya bafa, yomwe nthawi zambiri imaposa 80% monga momwe imayesedwera ndi selo ya Haring-Blum, imatsimikizira kufalikira kofanana kwa makulidwe a coating. Njirayi ndi yothandiza kwambiri pazinthu zazikulu, ndipo kusiyana kwa makulidwe nthawi zambiri kumakhala kochepera 15% pa workpiece. Kupsinjika kochepa kwamkati kwa malo osungira, nthawi zambiri kumakhala pansi pa 10 MPa monga momwe imayesedwera ndi spiral contractometer, kumachepetsa chiopsezo cha kusweka kapena kusweka.
▪ Njirayi ikuphatikizapo njira zowunikira nthawi yeniyeni kuti mudziwe zinthu zofunika monga kutentha, pH, ndi kuchuluka kwa zitsulo, kuonetsetsa kuti pulasitiki ndi yabwino nthawi zonse. Kugwiritsa ntchito zowonjezera zachilengedwe zomwe zili ndi zinthu zodzilamulira zokha kumathandizira kuti nthawi yosamba ikhale yayitali, nthawi zambiri kupitirira 12 MTO (kutembenuka kwachitsulo) popanda kuwonongeka kwakukulu kwa utoto. Njirayi idapangidwa kuti ikwaniritse miyezo yokhwima yamakampani, kuphatikiza ASTM B689 ndi ISO 1456 ya utoto wa nickel womwe uli ndi electrodepositioned.
