Magulu osiyanasiyana a Bonded NdfeB Magnet

Kufotokozera Kwachidule:

Bonded NdFeB, yopangidwa ndi Nd2Fe14B, ndi maginito opangira.Ndi maginito opangidwa ndi kusakaniza mwamsanga kuzimitsidwa NdFeB maginito ufa ndi binder kudzera "compression akamaumba" kapena "jekeseni akamaumba".Maginito oponderezedwa a NdFeB ndi maginito opangidwa ndi jekeseni a neodymium Iron boron ndi omwe amagwiritsidwa ntchito kwambiri pakati pawo.

Ili ndi njira zinayi zopangira, yoyamba ndikukankhira kuumba.(Maginito ufa ndi zomatira zimasakanizidwa mofanana mu chiŵerengero cha voliyumu pafupifupi 7: 3, kukulungidwa ku makulidwe ofunikira kenako ndikulimbitsidwa kuti apange chomaliza), chachiwiri ndikuumba jekeseni.(Sakanizani ufa wa maginito ndi chomangira, kutentha ndi knead, pre-granulate, youma, ndiyeno tumizani ndodo yozungulira yozungulira kuchipinda chotenthetsera kuti mutenthetse, bayani mu nkhungu kuti mupangire kuti mutenge chomalizidwa mutatha kuzirala), chachitatu ndi extrusion akamaumba.(Ndizofanana ndi njira yopangira jakisoni, kusiyana kokhako ndikuti pambuyo pakuwotcha, ma pellets amatulutsidwa mu nkhungu kudzera pabowo kuti apangidwe mosalekeza), ndipo chachinayi ndikumangirira (Sakanizani ufa wa maginito ndi binder molingana ndi chiŵerengero, granulate ndi kuwonjezera kuchuluka kwa cholumikizira wothandizira, kanikizani mu nkhungu, kulimbitsa pa 120 ° ~ 150 °, ndipo potsiriza pezani chomaliza.)

Choyipa ndichakuti kulumikizana kwa NdFeB kumayamba mochedwa, ndipo mphamvu zamaginito ndi zofooka, kuwonjezera apo, mlingo wa ntchito ndi wopapatiza, ndipo mlingowo ndiwochepa.

ubwino wake ndi mkulu remanence, mkulu mphamvu mphamvu, mkulu maginito mphamvu mankhwala, mkulu ntchito-mtengo chiŵerengero, kamodzi n'kupanga popanda processing yachiwiri, ndipo akhoza kukhala maginito zosiyanasiyana zovuta woboola pakati, amene angathe kuchepetsa kwambiri voliyumu ndi kulemera kwa galimoto.Ndipo imatha kukhala ndi maginito mbali iliyonse, yomwe ingathandize kupanga maginito amitundu yambiri kapena opanda malire.

Amagwiritsidwa ntchito kwambiri pazida zopangira ma ofesi, zida zamagetsi, zida zowonera, zida, ma motors ang'onoang'ono ndi makina oyezera, ma motor vibration motors, makina osindikizira maginito, chida champhamvu cholimba disk spindle motors HDD, ma motors ena ang'onoang'ono a DC ndi zida zamagetsi.

Product Mbali

Zogwirizana ndi maginito a NdFeB:
1. Maginito katundu pakati sintered NdFeB maginito ndi ferrite maginito, ndi mkulu ntchito isotropic okhazikika maginito ndi kusasinthasintha wabwino ndi bata.
2. Ikhoza kupangidwa kukhala maginito okhazikika ang'onoang'ono, mawonekedwe ovuta komanso olondola kwambiri a geometric ndi makina osindikizira ndi jekeseni.Zosavuta kukwaniritsa zopanga zazikulu zokha.
3. Itha kukhala ndi maginito kudzera njira iliyonse.Mizati yambiri kapena mizati yosawerengeka imatha kuzindikirika mu NdFeB yomangidwa.
4. Maginito omangidwa a NdFeB amagwiritsidwa ntchito kwambiri mumitundu yonse yamagetsi yaying'ono, monga mota ya spindle, motor synchronous, stepper motor, DC motor, brushless motor, etc.
