Ukuma nokulandelana kokubumba komazibuthe abamise okukhethekile

Umazibuthe, uzibuthe omise okukhethekile enqubweni yokukhiqiza kunzima ukwenza ukucubungula ngesikhathi esisodwa.

I-Magnet orientation kanye nokuhleleka kokwakheka: impusha kazibuthe kazibuthe ngemva kokuma, ukubumba kanye nokucindezela kwe-isostatic okwenziwe ngobuningi obungenalutho kuphansi kakhulu, okuyisici esibi ekukhiqizeni, akunalutho futhi kuqukethe ama-pores amaningi, ukukhangisa okulula kwenani elikhulu legesi eliqukethe. amanzi, kunqubo elandelayo ukuletha izinkinga nobunzima.Ngenxa yokuminyana okuphansi kwe-billet eluhlaza, izinga lokunciphisa i-sintering likhulu, ukuguquguquka okulula, isikali esilula ngenxa yokubekezelelana, ngakho-ke kuyadingeka ukuba sintering, futhi inqubo yezidingo zokuhlangenwe nakho kokusebenza kwe-sintering ziphakeme kakhulu.

Enqubweni yokulandelana kokuma kukazibuthe nokubumba, okungenalutho kudinga ukudlula ezinqubweni ezimbili lapho kufakwa esithandweni somlilo:

Ukuguga nokuguga: 

1. Sintering;Esimweni sokushisa okuphezulu isikhathi esithile, ukuminyana komzimba okubalulekile kuyathuthuka.Ukuminyana kwesihlobo kuye kwathuthuka kusuka ku-0.6-0.7 kuya ngaphezulu kuka-0.95.Ukwakheka kwangaphakathi kokusanhlamvu ngakunye kuphinde ku-homogenized.Isikhala phakathi kwezinhlayiya sincishisiwe, futhi umhwamuko wamanzi we-adsorbed uyaxoshwa.

2. Ukuguga:sintered NdFeb ozibutheukuminyana kwe-billet kuphezulu, i-Br iphakeme, kodwa ukuphoqelela nomkhiqizo wamandla kazibuthe awuphezulu.Lokhu kungenxa yokuthi isigaba esicebile nge-neodymium asihlakazwanga kahle.Emazingeni okushisa okuguga, ungqimba oluncane lwesigaba esinothe nge-neodymium luzungeza izinhlayiya zesigaba esiyinhloko futhi luzihlukanise komunye nomunye, lwakha ukwakheka kokuhlelwa okuvelele okuhambisana nokuphoqeleka okuphezulu.Ngemuva kokuguga, i-Br ye-billet yengezwe kancane kuphela, kodwa ukuphoqelela kuphindwe kabili.

Ukuma nokwakheka kokulandelana kukazibuthe ngemuva kokufakwa kwemikhiqizo engenalutho kudinga ukuhlaziywa futhi kuhlolwe ngale ndlela elandelayo ukuze kuqinisekiswe ukuthi umsebenzi kazibuthe ufanelekile:

A. Ukuhlolwa komsebenzi kaMagnetic ngemva kokushisa okuphezulu kwe-sintering;

B. Ukutholwa kokuminyana ngemva kokushisa okuphezulu kwe-sintering;

C. Ukuhlolwa kwesikali sokubukeka ngemva kokushisa okuphezulu kwe-sintering; 

D. Ngemva kokushisa okuphezulu kokushisa: ukuhlaziywa kwekhabhoni, umoya-mpilo kanye ne-nitrogen;

E. Ngemva kokudweba ijika lokususa uzibuthe ngemitha kazibuthe ukuze kutholwe ukuthi okungenalutho kuyagculiseka yini ngezinga likazwelonke.Njengoba ingxenye enkulu yeNdFeb uzibutheyenziwe ngensimbi, i-NdFeb i-oxidized kalula lapho ivezwe emoyeni noma endaweni emanzi.Electroplating Uzibuthe unomphelakuyindlela ebalulekile yokuhlobisa ukubukeka kodonsa futhi wengeze isikhathi sokulondoloza uzibuthe.I-Magnet surface processing ikakhulukazi i-zinc, i-zinc emnyama, i-nickel, ithusi, igolide, isiliva, i-epoxy resin.

I-Surface Plating ihlukile kumbala wayo ihlukile, isikhathi sokulondoloza asifani, ngasinye sinezinzuzo kanye nokubi. 

1. I-Zinc: ukubonakala kumhlophe kwesiliva, kungaba amahora angu-12 kuya kwangu-48 esifutho sikasawoti, ingahlanganiswa nokusetshenziswa kweglue (njenge-AB glue), uma umphumela we-electroplating muhle, ungagcinwa iminyaka emibili kuya kwemihlanu. , izindleko ze-electroplating ziphansi.

2. I-Nickel: ukubukeka kubukeka njengombala wensimbi engagqwali, obekwe ekubukeni komoya akulula ukwenza i-oxidize, ukubukeka okuhle, isicwebezelisi esihle, kungaba amahora angu-12 kuya kwangu-72 okuhlola isifutho sikasawoti.Okubi ukuthi akulula ukusebenzisa i-glue ukuze kuhlanganiswe, ukubukeka kwe-lubrication adhesion akuqinile, futhi ukugqoka kulula ukuwa.Ukusheshisa i-oxidation, imakethe manje isiyindlela ye-nickel eyengeziwe - i-copper - nickel plating yokwenza amahora angu-24-96 esifutho sikasawoti.

3. I-Black Zinc: ngokuya ngezidingo ezenziwe ngokwezifiso zekhasimende zendawo kazibuthe icutshungulwa ibe mnyama, isekelwe ekwelapheni kwamakhemikhali aphekiwe ukuze kwengeze ungqimba lwefilimu yesondlo emnyama, le filimu ingadlala futhi umphumela wokugcinwa kukazibuthe, ukwandisa isikhathi sokufutha usawoti.Kodwa ukubukeka kwayo kulula ukuklwejwa, kulahlekelwe umphumela wayo wesondlo.

4. I-Black Nickel: enezidingo ezifanayo ze-zinc plating emnyama, isekelwe ku-nickel plating ngemva kokwelashwa ngamakhemikhali ukwengeza ungqimba lwefilimu yokulungisa emnyama. 

5. Igolide: evame ukusetshenziswa e izesekeli uzibuthe ubucwebe, manje kukhona ethandwa kakhulu kazibuthe izandla imihlobiso. 

6. I-Epoxy resin: ukuze wengeze ukumelana nesifutho sikasawoti emkhiqizweni, ungqimba lukapende lwe-resin lwengezwa ngaphandle kukazibuthe ngemva kokufakwa kwe-nickel, okumnyama kakhulu.Kuyi-coating enokumelana okuhle nokugqwala ngaphandle kwe-magnetic coating.Ukuma kukazibuthe kanye nokwakheka ngokulandelana kukazibuthe, okusho ukwenza uzibuthe okubalulekile noma ukuntuleka kukazibuthe ukuze wengeze uzibuthe.Ngokuvamile, into kazibuthe okufanele ifakwe uzibuthe ingafakwa endaweni enamandla kazibuthe eyakhiwe ikhoyili okudlula ngayo amandla aqondile, futhi indawo kazibuthe engaphakathi kukazibuthe icutshungulwa yinkundla kazibuthe yangaphandle.
