Anisotropic Sintered NdFeB NIB Ring Permanent Magnet

Sintered NIB Magnets
Limanete tsa Sintered NIB li na le matla a phahameng ka ho fetisisa empa li lekantsoe ho li-geometri tse batlang li le bonolo ebile li ka ba brittle.Li entsoe ka khatello e etsang lisebelisoa tse tala hore e be li-blocks, ebe li feta ka mokhoa o rarahaneng oa ho futhumatsa.Ka mor'a moo, boloko e sehoa hore e be sebopeho 'me e koahetsoe ho thibela kutu.Limanete tse sirelelitsoeng hangata ke li-anisotropic, ho bolelang hore li na le khetho ea sebaka sa matla a tsona a khoheli.Magnetizing makenete khahlano le "thollo" ho tla fokotsa matla a makenete ka ho fihla ho 50%. Limanete tse fumanehang khoebong li lula li hokahantsoe ka tsela e ratoang ea matla a khoheli.

Demagnetization
Limanete tsa NIB ehlile ke limakete tse sa feleng, kaha li lahleheloa ke thein magnetism, kapa degauss ka tlhaho, hoo e ka bang 1% ka lekholong la lilemo. Ka kakaretso li sebetsa ka har'a mocheso oa -215 ° Fto 176 ° F (-138 ° C ho isa ho 80 ° ℃).Bakeng sa lits'ebetso tse hlokang mocheso o pharalletseng, ho sebelisoa makenete a Samarium Cobalt (SmCo).

Liaparo
Hobane NIB e sa koaeloang e tla senyeha ebe e oa ka lebaka la ho pepesehela sepakapaka, li rekisoa ka lesela le sireletsang.Seaparo se tloaelehileng ka ho fetisisa se entsoe ka nickel, le hoja liphahlo tse ling tse rekisoang li fana ka ho hanyetsa mocheso o phahameng, mongobo o phahameng, spray ea letsoai, solvents le likhase.

Kereiti
Limanete tsa NIB li tla ka limaraka tse fapaneng, tse tsamaellanang le matla a matla a tsona a khoheli, ho tloha ho N35 (e fokolang ka ho fetesisa ebile e theko e tlase haholo) ho isa ho N52 (e matla ka ho fetesisa, e turu haholo ebile e brittle). 52/35 = 1.49).Ho rona, ho tloaelehile ho fumana limatlase tsa maemo a bareki sebakeng sa N40 ho ea ho N42.Tlhahisong ea molumo, N35 hangata e sebelisoa ifsize le boima ba 'mele ha se taba e kholo kaha e theko e tlase.f boholo le boima ba 'mele ke lintlha tsa bohlokoa, limaraka tse holimo hangata li sebelisoa.Ho na le tefiso ea theko ea limakete tsa maemo a holimo ka ho fetesisa kahoo ho tloaelehile ho bona limakenete tsa N48 le N50 tse sebelisoang tlhahisong khahlano le N52.
