Uchwepheshe wezibuthe

Umuzwa Wokukhiqiza Weminyaka eyi-15
imikhiqizo

Amabanga ahlukene e-Bonded NdfeB Magnet

Incazelo emfushane:

I-Bonded NdFeB, eyakhiwe nge-Nd2Fe14B, iwuzibuthe wokwenziwa.Iwuzibuthe owenziwe ngokuxuba impushana kazibuthe ye-NdFeB ecisha ngokushesha kanye nesibopho “nge-compression molding” noma “i-injection molding”.Ozibuthe be-NdFeB abacindezelwe kanye nozibuthe be-neodymium be-Iron boron ababunjwe ngomjovo yibo abasetshenziswa kakhulu phakathi kwabo.


Imininingwane Yomkhiqizo

Omaka bomkhiqizo

Inezindlela ezine zokukhiqiza, eyokuqala icindezela ukubumba.(Impushana kazibuthe kanye ne-adhesive kuxutshwe ngokulinganayo ngenani lesilinganiso esingaba ngu-7:3, kusongwe kugqinsi oludingekayo bese kuqiniswa ukwenza umkhiqizo ophelile), okwesibili ukubumba umjovo.(Hlanganisa impushana kazibuthe nesibophelelo, ukushisa nokuxova, i-pre-granulate, yomile, bese uthumela induku yokuqondisa okuvunguzayo endaweni yokushisisa ukuze ifudumale, ijove endaweni yokubumba ukuze ibunjwe ukuze uthole umkhiqizo osuphelile ngemva kokupholisa), okwesithathu ukubunjwa kwe-extrusion.(Ngokuyisisekelo iyafana nendlela yokubumba umjovo, umehluko kuphela ukuthi ngemva kokushisisa, ama-pellets adluliselwa esikhunjini ngokusebenzisa imbobo ukuze abunjwe ngokuqhubekayo), kanti okwesine ukubumba kokucindezela (Hlanganisa impushana kazibuthe kanye ne-binder ngokusho isilinganiso, granulate bese wengeza inani elithile le-ejenti yokuhlanganisa, cindezela esibunjeni, uqinise ku-120°~150°, bese ekugcineni uthole umkhiqizo osuphelile.)

Ububi ukuthi i-NdFeB yokubopha iqala sekwephuzile, futhi izakhiwo kazibuthe zibuthakathaka, ngaphandle kwalokho, izinga lohlelo lokusebenza lincane, futhi umthamo nawo uncane.

Izinzuzo zayo i-remanence ephezulu, amandla aphezulu aphoqelelayo, umkhiqizo wamandla kazibuthe aphezulu, isilinganiso sentengo yokusebenza okuphezulu, ukwakheka kwesikhathi esisodwa ngaphandle kokucubungula okwesibili, futhi ingenziwa ibe yizibuthe ezihlukene eziyinkimbinkimbi, ezinganciphisa kakhulu ivolumu nesisindo imoto.Futhi kungenziwa uzibuthe kunoma iyiphi indlela, okungase kube lula ukukhiqizwa kozibuthe bezigxobo eziningi noma ezingapheli.

Isetshenziswa kakhulu emishinini ye-automation yasehhovisi, izinto zikagesi, izinto ezilalelwayo nezibukwayo, izinsimbi, izinjini ezincane nemishini yokulinganisa, amamotho wokudlidliza omakhalekhukhwini, amarola kazibuthe wephrinta, ithuluzi lamandla i-hard disk spindle motors HDD, amanye ama-micro DC motors nezinsimbi ezizenzakalelayo.

Isici soMkhiqizo

Izici zikazibuthe ze-Bonded NdFeB:
1. Impahla kazibuthe phakathi Sintered NdFeB uzibuthe futhi ferrite uzibuthe, kuba high ukusebenza uzibuthe isotropic unomphela nokuvumelana okuhle nokuzinza.
2. Angenziwa amamagnethi ahlala unomphela amasayizi amancane, izimo eziyinkimbinkimbi kanye nokunemba okuphezulu kwejometri ngokubumba komshini kanye nokubunjwa komjovo.Kulula ukufeza ukukhiqizwa okuzenzakalelayo okukhulu.
3. Ingenziwa uzibuthe nganoma iyiphi indlela.Izigxobo eziningi noma izigxobo ezingenakubalwa zingabonakala ku-NdFeB eboshiwe.
4. Ozibuthe be-NdFeB ababoshiwe basetshenziswa kakhulu kuzo zonke izinhlobo zamamotha amancane, njenge-spindle motor, motor synchronous, stepper motor, DC motor, brushless motor, njll.
