Momwe mungapangire Magnet a Sintered Neodymium?

Sintered NdFeB maginitondi maginito aloyi opangidwa kuchokera kuNd, Fe, B ndi zinthu zina zachitsulo. Ili ndi maginito amphamvu kwambiri, mphamvu yokakamiza yabwino.Amagwiritsidwa ntchito kwambiri mu mini-motor, ma jenereta amphepo, mita, masensa, okamba, maginito kuyimitsidwa, makina otumizira maginito ndi ntchito zina zamafakitale.Zosavuta kwambiri kuti dzimbiri m'malo achinyezi, chifukwa chake ndikofunikira kuchita chithandizo chapamwamba malinga ndi zomwe makasitomala amafuna.Titha kupereka zokutira, monga Zinc, Nickel, Nickel-mkuwa-nickel, Silver, golide-plating, Epoxy ❖ kuyanika, etc. Gulu: N35-N52, N35M-48M, N33H-N44H, N30SH-N42SH, N28UH-N38UH, N28EH-N35EH

Kukonzekera kwa Sintered Neodymium Magnet Manufacturing

Zopangira maginito ndi zitsulo zina zimawonekera pafupipafupi ndipo zimasungunuka mu ng'anjo yolowera.

Akamaliza njira zosiyanasiyana masitepe, ndi ingots ndi pulverized mu particles kuti ndi microns angapo kukula.Pofuna kupewa oxidation kuti isachitike, tinthu tating'onoting'ono timatetezedwa ndi nayitrogeni.

Maginito particles amayikidwa mu jig ndipo mphamvu ya maginito imagwiritsidwa ntchito pamene maginito amakanikizidwa mu mawonekedwe makamaka.Pambuyo popanga koyamba, kukanikiza kwa isostatic kwa mafuta kumapita patsogolo kuti apange mawonekedwe.

Maginito particles amaikidwa mu ingots kuti mbamuidwa ndipo adzakhala kutentha mankhwala mu ng'anjo sintering.Kuchulukana kwa ma ingots am'mbuyomu kumangokhudza 50% ya kachulukidwe weniweni wa sintering.Koma pambuyo sinteing, kachulukidwe weniweni ndi 100%.Kupyolera mu njirayi, kuyeza kwa ingots kumachepa pafupifupi 70% -80% ndipo kuchuluka kwake kumachepetsedwa ndi 50%.

Zinthu zoyambira maginito zakhazikitsidwa pambuyo poti sintering ndi ukalamba watha.Miyezo yayikulu kuphatikiza kuchulukira kwa remnant flux, kukakamiza, komanso kuchuluka kwa mphamvu zamagetsi kumalembedwa.

Maginito okhawo omwe adadutsa pakuwunika amatumizidwa kunjira zotsatizana, monga kukonza ndi kusonkhanitsa.

Chifukwa cha shrinkage kuchokera ku sintering, miyeso yofunikira imatheka pogaya maginito ndi ma abrasives.Ma abrasives a diamondi amagwiritsidwa ntchito pochita izi chifukwa maginito ndi ovuta kwambiri.

Kuti agwirizane bwino ndi malo omwe angagwiritsire ntchito, maginito amapangidwa mosiyanasiyanamankhwala pamwamba.Maginito a Nd-Fe-B nthawi zambiri amakhala ndi dzimbiri ndikuwoneka ngati maginito a NiCuNi, Zn, Epoxy, Sn, Black Nickel.

Pambuyo plating, miyeso yogwirizana ndi kuyang'ana kowoneka kudzachitidwa kuti titsimikizire mawonekedwe athu amagetsi.Kupatula apo, kuti titsimikizire kulondola kwakukulu, tifunikanso kuyesa kukula kwake kuti tiwongolere kulolerana.

Pamene maonekedwe ndi kukula kulolerana kwa maginito kuyeneretsedwa, ndi nthawi yopangira magnetization maginito.

Pambuyo poyang'ana ndi magnetize, maginito ali okonzeka kunyamula ndi bokosi lamapepala, ngakhale mphasa yamatabwa monga momwe makasitomala amafunira.Magnetic Flux imatha kupatulidwa ndi chitsulo kuti ikhale ndi mpweya kapena nthawi yoperekera.
