Imagnethi, umazibuthe omilise okhethekileyo kwinkqubo yemveliso kunzima ukwenza ukwakheka kwexesha elinye.
Ukuqhelaniswa nemagnethi kunye nocwangco: umgubo wemagnethi wemagnethi emva kokuqhelaniswa, ukubumba kunye nokucinezelwa kwe-isostatic okwenziwe ngoxinaniso olungenanto luphantsi kakhulu, into engalunganga kwimveliso, ingenanto kwaye iqulathe iipores ezininzi, ukufakwa okulula kwenani elikhulu legesi equlathe amanzi, kwinkqubo elandelayo ukuzisa ingxaki kunye nobunzima.Ngenxa yoxinano oluphantsi lwe-billet eluhlaza, ireyithi yokunciphisa i-sintering inkulu, i-deformation elula, isikali esilula ngaphandle kokunyamezela, ngoko ke kuyafuneka ukuba sintering, kwaye inkqubo yeemfuno zamava e-sintering ziphezulu kakhulu.
Kwinkqubo yolandelelwano lokuqhelaniswa nemagnethi kunye nokubumba, okungenanto kufuneka kudlule kwiinkqubo ezimbini xa ifakwa kwiziko lokutshisa:
Sintering kunye nokwaluphala:
1. Sintering;Kwisithuba sobushushu obuphezulu kangangexesha elithile, ukuxinana komzimba okubalulekileyo kuqhubekela phambili.Uxinzelelo olunxulumeneyo luphuculwe ukusuka kwi-0.6-0.7 ukuya ngaphezulu kwe-0.95.Ukubunjwa kwangaphakathi kweenkozo nganye ku-homogenized ngakumbi.Isithuba phakathi kwamaqhekeza siyancitshiswa, kwaye umphunga wamanzi adsorbed uyakhutshwa.
2. Ukuguga:sintered NdFeb umazibutheUbuninzi be-billet buphezulu, i-Br iphezulu, kodwa ukunyanzeliswa kunye nemveliso yamandla omagnetic ayikho phezulu.Oku kungenxa yokuba isigaba esityebileyo se-neodymium asisasazwanga kakuhle.Kwiqondo lokushisa lokuguga, i-neodymium-rich-rich phase ebhityileyo ijikeleze amasuntswana esigaba esiphambili kwaye iwahlukanise omnye komnye, yenze ulungelelwaniso olubalaseleyo olulungele ukunyanzeliswa okuphezulu.Emva kokuguga, i-Br ye-billet yongezwa nje kancinci, kodwa ukunyanzeliswa kuphindwe kabini.
Ukuqhelaniswa kunye nokwenza ulandelelwano lwemagnethi emva kokufakwa kweemveliso ezingenanto kufuneka zihlalutywe kwaye zivavanywe ngolu hlobo lulandelayo ukuqinisekisa ukuba umsebenzi wemagnethi ufanelekile:
A. Uvavanyo lomsebenzi weMagnetic emva kokushisa okuphezulu kwe-sintering;
B. Ukufumanisa ukuxinana emva kokushisa okuphezulu kwe-sintering;
C. Ukuhlolwa kwesikali sokubonakala emva kokushisa okuphezulu kwe-sintering;
D. Emva kokushisa okuphezulu kokushisa: uhlalutyo lwekhabhoni, ioksijini kunye nenitrogen;
E. Emva kokuzoba ijiko le-demagnetization ngemitha yemagnethi ukumisela ukuba into engenanto yanelisekile ngumgangatho wesizwe.Ekubeni umlinganiselo omkhulu weNdFeb umazibutheyenziwe ngentsimbi, i-NdFeb i-oxidized ngokulula xa ibonakaliswe emoyeni okanye kwindawo efumileyo.Electroplating Permanent umazibutheyindlela ebalulekileyo yokuhombisa inkangeleko yemagnethi kunye nokongeza ixesha lokugcinwa kwemagnethi.Ukusetyenzwa komphezulu wemagnethi ikakhulu i-zinc, i-zinc emnyama, i-nickel, ubhedu, igolide, isilivere, i-epoxy resin.
I-Surface plating ihluke kumbala wayo yahlukile, ixesha lokulondoloza alifani, nganye ineenzuzo kunye nokungonakali.
1. I-Zinc: imbonakalo yesilivere emhlophe, ingaba yi-12 kwiiyure ze-48 zokutshiza ityuwa, inokudibaniswa kunye nokusebenzisa iglue (njenge-AB glue), ukuba i-electroplating effect ilungile, inokugcinwa iminyaka emibini ukuya kwemihlanu. , ixabiso le-electroplating liphantsi.
2. I-Nickel: imbonakalo ibonakala ngathi umbala wensimbi engenasici, ibekwe kwimbonakalo yomoya ayilula ukuba i-oxidize, imbonakalo enhle, i-gloss enhle, ingaba yi-12 kwiiyure ze-72 zovavanyo lokutshiza ityuwa.Ukungalungi kukuba akulula ukusebenzisa iglue kwi-bonding, ukubonakala kwe-lubrication adhesion ayiqini, kwaye i-coating ilula ukuwa.Ukukhawulezisa i-oxidation, imarike ngoku ininzi ye-nickel - i-copper - i-nickel plating indlela yokwenza iiyure ezingama-24-96 zokutshiza ityuwa.
3. I-Zinc emnyama: ngokweemfuno ezilungiselelwe umthengi zomphezulu wemagnethi icutshungulwa ibe mnyama, isekelwe kwisiseko sonyango lwekhemikhali eyenziwe yagalvanized ukongeza umaleko wefilimu yokugcina emnyama, le filimu inokudlala kwakhona umphumo wokugcinwa kwemagnethi, ukwandisa ixesha lokutshiza ityuwa.Kodwa ukubonakala kwayo kulula ukukhatywa, ukulahlekelwa yimpembelelo yayo yokugcina.
4. I-Nickel emnyama: kunye neemfuno ezifanayo ze-zinc plating emnyama, isekelwe kwi-nickel plating emva kokunyangwa kweekhemikhali ukongeza umaleko wefilimu yokugcina emnyama.
5. Igolide: isetyenziswa ngokuqhelekileyo kwizincedisi zemagnethi zobucwebe, ngoku kukho izihombiso ezininzi ezithandwa kakhulu zezandla zemagneti.
6. I-Epoxy resin: ukuze ungeze ukuxhathisa ityuwa kwimveliso, umaleko wepeyinti ye-resin yongezwa ngaphandle kwemagnethi emva kwe-nickel plating, eninzi emnyama.Lutyatyazo olunokumelana ne-corrosion elungileyo ngaphandle kwengubo yemagnethi.Ukuqhelaniswa nemagnethi kunye nokwakheka ngokolandelelwano lwemagnethi umazibuthe, intsingiselo kukwenza imagnethi imathiriyeli yemagnethi okanye ukungabikho kwemagnethi ukongeza umazibuthe.Ngokubanzi, into enemagnethi eza kwenziwa umazibuthe inokubekwa kwindawo eyomeleleyo yamagnetic eyenziwe yicoil ekugqithiswa ngayo umsinga othe ngqo, kunye nemagnethi engaphakathi kwimagnethi ishukunyiswa yintsimi yangaphandle.
