Ukuguqulwa ngakunye komkhiqizo kufana nezimonyo zabantu. Ingaphezulu lidinga ukumbozwa ngezendlalelo ezimbalwa zokuqukethwe ukuze kuqedelwe inqubo yokuhlobisa ngaphezulu. Ubukhulu be-coating buvezwa ngama-microns. Ngokuvamile, ububanzi bezinwele bungama-microns angamashumi ayisikhombisa noma angamashumi ayisishiyagalombili, futhi ukumbozwa kwensimbi kuyingxenye yezinkulungwane ezimbalwa zazo. Umkhiqizo wenziwe ngenhlanganisela yezinsimbi ezihlukahlukene futhi ugcwele izingqimba eziningana zezinsimbi ezahlukene ukuze uqedele ukwakheka. inqubo. Lesi sihloko sethula kafushane ulwazi olufanele lwe-electroplating kanye nokufakwa kombala. Okuqukethwe okwereferensi ngabangane abathenga futhi banikeze amasistimu wokupakisha wekhwalithi ephezulu:
I-Electroplating iyinqubo esebenzisa isimiso se-electrolysis ukuze icwecwe ungqimba oluncane lwezinye izinsimbi noma ama-alloys ebusweni bezinsimbi ezithile. Kuyinqubo esebenzisa i-electrolysis ukuze inamathisele ifilimu yensimbi ebusweni bensimbi noma ezinye izingxenye ezibonakalayo ukuze kuvinjelwe i-Metal oxidation (efana nokugqwala), ithuthukisa ukumelana nokuguga, ukuguquguquka, ukukhanya, ukumelana nokugqwala (izinsimbi ezimboziwe ngokuvamile ziyizinsimbi ezimelana nokugqwala. ) futhi ithuthukisa ukubukeka.
Isimiso
I-Electroplating idinga i-low-voltage, amandla amanje aphezulu anikezela amandla ethangini le-electroplating kanye nedivayisi ye-electrolytic ehlanganisa isixazululo sokucwenga, izingxenye ezizofakwa (i-cathode) ne-anode. Inqubo ye-electroplating iyinqubo lapho ama-ion ensimbi esixazululweni se-plating ancishiswa abe ama-athomu ensimbi ngokusabela kwe-electrode ngaphansi kwesenzo senkundla kagesi yangaphandle, futhi ukufakwa kwensimbi kwenziwa ku-cathode.
Izinto ezisetshenziswayo
Iningi lezingubo zokugqoka ziyinsimbi eyodwa noma ama-alloys, njenge-titanium, i-palladium, i-zinc, i-cadmium, igolide noma ithusi, ithusi, njll; kukhona futhi izingqimba zokuhlakazeka, njenge-nickel-silicon carbide, i-nickel-fluorinated graphite, njll.; kanye nezendlalelo zokuvala, njengensimbi isendlalelo se-Copper-nickel-chromium kunsimbi, isendlalelo sesiliva-idium kunsimbi, njll. Ngokungeziwe kunsimbi esekelwe kunsimbi, insimbi nensimbi engagqwali, izinto eziyisisekelo ze-electroplating nazo zihlanganisa okungeyona insimbi. izinsimbi, noma amapulasitiki e-ABS, i-polypropylene, i-polysulfone namapulasitiki e-phenolic. Kodwa-ke, amapulasitiki kufanele asebenze ngokukhethekile kanye nokwelashwa kokuzwela ngaphambi kwe-electroplating.
Umbala wokucwenga
1) Ukufakwa kwensimbi eyigugu: njengeplatinamu, igolide, i-palladium, isiliva;
2) Ukufakwa kwensimbi okujwayelekile: njengeplatinamu yokulingisa, isibhamu esimnyama, i-nickel-free tin cobalt, ithusi lasendulo, ithusi elibomvu lasendulo, isiliva lasendulo, ithini lasendulo, njll.
Ngokusho kobunzima benqubo
1) Imibala ejwayelekile yokuhlanganisa: iplatinum, igolide, i-palladium, isiliva, iplatinamu yokulingisa, isibhamu esimnyama, i-nickel-free tin cobalt, i-pearl nickel, upende omnyama;
2) I-Plating ekhethekile: i-antique plating (kufaka phakathi i-patina efakwe amafutha, i-patina edayiwe, i-patina enezintambo), imibala emibili, i-sandblasting plating, i-brush line plating, njll.
1 iplathinamu
Iyinsimbi ebizayo futhi eyivelakancane. Umbala umhlophe qhwa. Inezindawo ezizinzile, ukumelana okuhle kokugqoka, ubulukhuni obuphezulu kanye nesikhathi eside sokugcina umbala. Ingenye yemibala engaphezulu ye-electroplating. Ugqinsi lungaphezu kwama-microns angu-0.03, futhi i-palladium ngokuvamile isetshenziswa njengesendlalelo esingezansi ukuze ibe nomphumela omuhle we-synergistic, futhi uphawu lungagcinwa iminyaka engaphezu kwengu-5.
2 iplatinamu yokulingisa
Insimbi ye-electroplating iyingxubevange ye-copper-tin (Cu/Zn), futhi iplatinamu yokulingisa ibizwa nangokuthi i-white copper-tin. Umbala usondelene kakhulu negolide elimhlophe futhi uphuzi kancane kunegolide elimhlophe. Impahla ithambile futhi iyaphila, futhi ukunamathela okungaphezulu kulula ukufiphala. Uma ivaliwe, ingashiywa isigamu sonyaka.
3 igolide
Igolide (Au) liyinsimbi eyigugu. I-plating yokuhlobisa evamile. Izilinganiso ezihlukene zezithako ziza ngemibala ehlukene: 24K, 18K, 14K. Futhi kulolu hlelo kusuka kokuphuzi kuya kokuluhlaza, kuzoba nomehluko othile ngombala phakathi kogqinsi oluhlukene. Inezindawo ezizinzile futhi ubulukhuni bayo ngokuvamile buyi-1/4-1/6 yeplatinamu. Ukumelana nokugqoka kwayo kumaphakathi. Ngakho-ke, impilo yayo yeshalofu yombala iyisilinganiso. I-rose gold yenziwe nge-alloy yegolide-yethusi. Ngokwesilinganiso, umbala uphakathi kophuzi osagolide nokubomvu. Uma iqhathaniswa namanye amagolide, idlangile, inzima ukulawula umbala, futhi ivame ukuhluka ngemibala. Isikhathi sokugcina umbala asisihle njengeminye imibala esagolide futhi sishintsha umbala kalula.
4 isiliva
Isiliva (Ag) insimbi emhlophe esebenza kakhulu. Isiliva lishintsha kalula umbala lapho lichayeke kuma-sulfide nama-chloride emoyeni. I-Silver plating ngokuvamile isebenzisa ukuvikelwa kwe-electrolytic kanye nokuvikelwa kwe-electrophoresis ukuqinisekisa impilo yokucwenga. Phakathi kwazo, impilo yesevisi yokuvikelwa kwe-electrophoresis yinde kunaleyo ye-electrolysis, kodwa iphuzi kancane, imikhiqizo ecwebezelayo izoba nezimbobo ezincane, futhi izindleko zizokhuphuka. I-Electrophoresis yakheka ku-150 ° C, futhi imikhiqizo evikelwe yiyo akulula ukuphinda isebenze futhi ivame ukuchithwa. I-electrophoresis yesiliva ingagcinwa isikhathi esingaphezu konyaka ongu-1 ngaphandle kokushintsha umbala.
5 isibhamu esimnyama
Metal material nickel/zinc alloy Ni/Zn), ebizwa nangokuthi isibhamu esimnyama noma i-nickel emnyama. Umbala wokucwenga umnyama, umpunga kancane. Ukuzinza kwendawo kuhle, kodwa kujwayele ukufaka imibala emazingeni aphansi. Lo mbala we-plating ngokwawo uqukethe i-nickel futhi awukwazi ukusetshenziselwa i-nickel-free plating. Ukufakwa kombala akulula ukuphinda kusebenze futhi kulungiswe.
6 ama-nickels
I-Nickel (Ni) impunga-mhlophe futhi iyinsimbi enokuqina okuhle kakhulu. Ngokuvamile isetshenziswa njengesendlalelo sokuvala se-electroplating ukuze kuthuthukiswe impilo yesevisi ye-electroplating. Inekhono elihle lokuhlanzeka emkhathini futhi ingamelana nokugqwala okuvela emkhathini. I-nickel iqinile futhi i-brittle, ngakho-ke ayifanele imikhiqizo edinga ukuguqulwa ngesikhathi se-electroplating. Lapho imikhiqizo ye-nickel-plated ikhubazekile, ukugqoka kuzoxebuka. I-nickel ingabangela ukungezwani komzimba kwabanye abantu.
7 I-tin-cobalt engena-nickel
Izinto ezibonakalayo ziyi-tin-cobalt alloy (Sn/Co). Umbala umnyama, usondelene nesibhamu esimnyama (ompunga kancane kunesibhamu esimnyama), futhi iyi-plating emnyama engena-nickel. Ingaphezulu lizinzile, futhi izinga eliphansi le-electroplating livame ukuba nombala. Ukufakwa kombala akulula ukuphinda kusebenze futhi kulungiswe.
8 pearl nickel
Impahla yayo yi-nickel, ebizwa nangokuthi i-sand nickel. Ngokuvamile isetshenziswa njengesendlalelo esingaphansi esifakwe ngaphambili senqubo yombala wenkungu. Okumpunga ngombala, indawo yesibuko engacwebezeli, nokubukeka okuthambile okunjengenkungu, njenge-satin. Izinga le-atomization alizinzile. Ngaphandle kokuvikelwa okukhethekile, ngenxa yethonya lezinto zokwakha isihlabathi, kungase kube nokuguqulwa kombala ekuxhumaneni nesikhumba.
9 umbala wenkungu
Isekelwe ku-pearl nickel ukwengeza umbala ongaphezulu. Inomphumela wenkungu futhi i-matte. Indlela yayo ye-electroplating i-pre-plated pearl nickel. Ngenxa yokuthi umthelela we-atomization we-pearl nickel kunzima ukuwulawula, umbala ongaphezulu awuhambisani futhi uthambekele ekuhlukeni kombala. Lo mbala wokucwebezelisa awukwazi ukusetshenziswa nge-nickel-free plating noma ngetshe ngemva kokucwenga. Lo mbala we-plating kulula ukwenza i-oxidize, ngakho-ke ukunakwa okukhethekile kufanele kukhokhwe ekuvikelweni.
10 ibhulashi wire Plating
Ngemuva kokufakwa kwethusi, imigqa ixutshwa ngethusi, bese kungezwa umbala ongaphezulu. Kukhona umuzwa wemigqa. Umbala wokubukeka kwawo ngokuyisisekelo uyafana nowombala wokucwenga ojwayelekile, kodwa umehluko wukuthi kukhona imigqa phezulu. Izintambo zokuxubha azikwazi ukuba yi-nickel-free plating. Ngenxa ye-nickel-free plating, ubude bazo bokuphila abunakuqinisekiswa.
11 ukuqhunyiswa kwesihlabathi
I-Sandblasting nayo ingenye yezindlela zombala wenkungu ye-electroplating. I-copper plating i-sandblasted bese i-electroplated. Ingaphezulu le-matte liyisihlabathi, futhi umbala ofanayo we-matte usobala kakhulu kunomphumela oyisihlabathi. Njengokufaka ibhulashi, i-nickel-free plating ayikwazi ukwenziwa.
