Uhlobo 1:Izingubo zokugqoka (noma zokuguqula).
I-Metal Plating iyinqubo yokuguqula ingaphezulu le-substrate ngokuyimboza ngezendlalelo ezincane zenye insimbi njenge-zinc, i-nickel, i-chromium noma i-cadmium.
I-Metal Plating ingathuthukisa ukuqina, ukungqubuzana kwendawo, ukumelana nokugqwala nokubukeka kobuhle bengxenye. Kodwa-ke, imishini yokucwenga ingase ingafaneleki ukuqeda ukungapheleli kwendawo yensimbi. Kunezinhlobo ezimbili ezinkulu ze-plating:
Uhlobo 2:I-Electroplating
Le nqubo yokucwenga ihlanganisa ukucwiliswa kwengxenye ebhavini eliqukethe ama-ion ensimbi ukuze kuhlanganiswe. Umsinga oqondile ube usuhanjiswa ensimbi, ufaka ama-ion ensimbi bese wenza ungqimba olusha phezu kwendawo.
Uhlobo 3:I-electroless Plating
Le nqubo ayisebenzisi ugesi ngoba iyi-autocatalytic plating engadingi amandla angaphandle. Esikhundleni salokho, ingxenye yensimbi icwiliswa kuzixazululo zethusi noma ze-nickel ukuze kuqalwe inqubo ephula ama-ion ensimbi futhi yakhe isibopho samakhemikhali.
Uhlobo 4:I-anodizing
Inqubo ye-electrochemical enikela ekudalweni kwesiphetho se-anodic oxide esihlala isikhathi eside, esikhangayo, nesimelana nokugqwala. Lokhu kuqedwa kusetshenziswa ngokucwilisa insimbi kubhavu we-acid electrolyte ngaphambi kokudlulisa amandla kagesi phakathi nendawo. I-aluminium isebenza njenge-anode, ene-cathode ehlala ngaphakathi kwe-anodizing tank.
Ama-ion oksijini akhishwe yingxube ye-electrolyte nama-athomu e-aluminium ukuze akhe i-anodic oxide endaweni yokusebenza. Ngakho-ke, i-anodizing iyi-oxidation elawulwa kakhulu ye-substrate yensimbi. Ivame ukusetshenziselwa ukuqeda izingxenye ze-aluminium, kodwa futhi iyasebenza ezinsimbi ezingenayo insimbi njenge-magnesium ne-titanium.
Uhlobo 5:Ukugaya insimbi
Imishini yokugaya isetshenziswa abakhiqizi ukuze bushelelezi izindawo zensimbi ngokusetshenziswa kwama-abrasives. Ingesinye sezigaba zokugcina enqubweni yokwenza imishini, futhi isiza ekwehliseni ubulukhuni obusele ensimbi kusukela ezinqubweni zangaphambilini.
Kunemishini eminingi yokugaya etholakalayo, ngayinye ihlinzeka ngamazinga ahlukahlukene obushelelezi. Imishini yokugaya ingaphezulu iyona esetshenziswa kakhulu, kodwa kuneminye imishini yokugaya ekhethekile etholakalayo efana ne-Blanchard grinders kanye ne-centerless grinders.
Uhlobo 6:Ukupholisha/Ukubhuza
Ngokupholishwa kwensimbi, izinto zokugwaza zisetshenziselwa ukunciphisa ubulukhuni obungaphezulu bengxube yensimbi ngemva komshini. Lawa ma-powder abrasive asetshenziswa ngokuhambisana namasondo azwakalayo noma esikhumba ukuze apholishe futhi abhuqe izindawo zensimbi.
Ngaphandle kokunciphisa ukuhwaqeka kwendawo, ukupholisha kungathuthukisa ukubukeka kwengxenye — kodwa lena inhloso eyodwa kuphela yokupholisha. Ezimbonini ezithile, ukupholisha kusetshenziselwa ukudala imikhumbi ehlanzekile nezingxenye.
Uhlobo 7:I-Electropolishing
Inqubo ye-electropolishing iphambene nenqubo ye-electroplating. I-Electropolishing isusa ama-ion ensimbi ebusweni bezingxenye zensimbi kunokuba iwafake. Ngaphambi kokusebenzisa amandla kagesi, i-substrate icwiliswa okugeza kwe-electrolyte. I-substrate iguqulwa ibe i-anode, nama-ion ageleza kuwo ukuze asuse amaphutha, ukugqwala, ukungcola nokunye. Ngenxa yalokho, ingaphezulu liyapholishwa futhi libushelelezi, alinazo izigaxa noma imfucumfucu engaphezulu.
Uhlobo 8:Ukudweba
I-Coating yigama elibanzi elihlanganisa izigaba ezihlukene zokuqeda phezulu. Inketho evamile futhi engabizi kakhulu ukusebenzisa amapende okuhweba. Amanye amapende angangeza umbala kumkhiqizo wensimbi ukuze ubonakale ukhanga kakhulu. Ezinye zisetshenziselwa futhi ukuvimbela ukugqwala.
Uhlobo 9:I-Powder enamathela
I-Powder coating, uhlobo lwesimanje lomdwebo, nakho kuyinketho. Isebenzisa i-electrostatic charge, inamathisela izinhlayiya zempushana ezingxenyeni zensimbi. Ngaphambi kokuphathwa ngokushisa noma imisebe ye-ultraviolet, izinhlayiya zempushana zimboza ngokulinganayo indawo ebonakalayo. Le nqubo iyashesha futhi isebenza kahle ekupendeni izinto zensimbi ezifana namafreyimu ebhayisikili, izingxenye zemoto kanye nokwakhiwa okuvamile.
Uhlobo 10:Ukuqhuma
Ukuqhuma kwe-abrasive kuvame ukusetshenziselwa imikhiqizo edinga ukuthungwa kwe-matte okungaguquki. Kuyindlela eshibhile yokuhlanganisa ukuhlanzwa kwendawo nokuphothula umsebenzi owodwa.
Ngesikhathi senqubo yokuqhuma, ukugeleza kwe-abrasive yokucindezela okuphezulu kufafaza indawo yensimbi ukuze kulungiswe ukuthungwa, kususe udoti futhi kukhiphe isiphetho esibushelelezi. Ingabuye isetshenziselwe ukulungiswa kwendawo, ukucwenga kanye nokugqoka ukuze kunwetshwe impilo yezinto zensimbi.
Uhlobo 11:Ukuxubha
Ukuxubha kuwumsebenzi ofanayo nokupholisha, ukukhiqiza ukuthungwa kwendawo efanayo nokushelela ngaphandle kwengxenye. Inqubo isebenzisa amabhande abrasive namathuluzi ukuze kudluliselwe ukuphela okusanhlamvu okuqondile phezulu.
Imiphumela ingase yehluke kuye ngokuthi inqubo isetshenziswa kanjani umenzi. Ukuhambisa ibhulashi noma ibhande liye ohlangothini olulodwa, isibonelo, kungasiza ekudaleni imiphetho eyindilinga kancane ngaphezulu.
Kunconywa kuphela ukuthi kusetshenziswe ezintweni ezimelana nokugqwala njengensimbi engagqwali, i-aluminium nethusi.
I-JINDALAI iyiqembu lensimbi ehamba phambili e-China, singahlinzeka zonke iziqephu zensimbi ngokusekelwe ezidingweni zakho, Nikeza isisombululo esifanele kakhulu sephrojekthi yakho.
