Nanone izwi nka neo magnet, neodymium magnet ni ubwoko bwa rare-earth magnets bugizwe na neodymium, icyuma na boron. Nubwo hari izindi rare-earth magnets — harimo na samarium cobalt — neodymium ni yo ikunze kugaragara cyane. Ikora imbaraga zikomeye za rukuruzi, bigatuma habaho urwego rwo hejuru rw'imikorere. Nubwo waba warumvise ibya neodymium magnets, birashoboka ko hari ibintu bimwe na bimwe utazi kuri izi rare-earth magnets zikunzwe cyane.
✧ Incamake ya Neodymium Magnets
Inyito ya neodymium, yiswe rukuruzi ikomeye cyane ku isi, ni rukuruzi zikozwe muri neodymium. Kugira ngo dushyire imbaraga zazo mu buryo bugaragara, zishobora gukora imbaraga rukuruzi zifite tesla zigera kuri 1.4. Birumvikana ko Neodymium ari ikintu kidasanzwe gifite umubare wa atome 60. Yavumbuwe mu 1885 n'umuhanga mu bya shimi Carl Auer von Welsbach. Ibyo bivuzwe, ni nyuma y'imyaka hafi ijana gusa, kugeza ubwo rukuruzi za neodymium zavumbuwe.
Imbaraga zitagereranywa za neodymium magnets zituma ziba amahitamo meza cyane ku bikorwa bitandukanye by'ubucuruzi, bimwe muri byo birimo ibi bikurikira:
ㆍDisiki zikomeye (HDD) kuri mudasobwa
ㆍIngufuri z'inzugi
ㆍMoteri z'amashanyarazi
ㆍImashini zitanga amashanyarazi
ㆍImirongo y'amajwi
ㆍIbikoresho by'amashanyarazi bitagira insinga
ㆍUbuyobozi bw'amashanyarazi
ㆍIndangururamajwi na ecouteur
ㆍIbikoresho byo gukuraho imiyoboro y'ubucuruzi

✧ Amateka ya Neodymium Magnets
Ingufu za Neodymium zavumbuwe mu ntangiriro za 1980 na General Motors na Sumitomo Special Metals. Izo sosiyete zavumbuye ko binyuze mu guhuza neodymium n'ingano nto y'icyuma na boron, zashoboye gukora ingufu zikomeye. General Motors na Sumitomo Special Metals basohoye ingufu za mbere za neodymium ku isi, zitanga ubundi buryo buhendutse bwo gusimbura izindi ngufu zidasanzwe ku isoko.
✧ Neodymium VS Ceramic Magnets
Ni gute magneti za neodymium zigereranywa na magneti za ceramic neza? Nta gushidikanya ko magneti za ceramic zihendutse, bigatuma ziba amahitamo akunzwe n'abaguzi. Ariko, ku bikorwa by'ubucuruzi, nta kindi gisimbura magneti za neodymium. Nkuko byavuzwe mbere, magneti za neodymium zishobora gukora magnetic fields zifite tesla zigera kuri 1.4. Mu kugereranya, magneti za ceramic muri rusange zikora magnetic fields zifite tesla 0.5 kugeza kuri 1 gusa.
Sukuru za neodymium si zo zikomeye cyane kurusha sukuru za ceramic gusa, ahubwo nazo zirakomeye. Sukuru za ceramic zirapfa, bigatuma zishobora kwangirika. Iyo ujugunye ceramic hasi, hari amahirwe menshi ko izacika. Sukuru za Neodymium zo zirakomera cyane ku mubiri, bityo ntizishobora kuvunika cyane iyo ziguye cyangwa zihuye n'ibintu bizitera stress.
Ku rundi ruhande, magneti za ceramic zirwanya ingese kurusha magneti za neodymium. Nubwo zihura n'ubushuhe buri gihe, magneti za ceramic muri rusange ntizishobora kwangirika cyangwa ngo zigire ingese.
✧ Umutanga Magnet ya Neodymium
AH Magnet ni ikigo gitanga magnets za rare earth cyihariye mu bushakashatsi, guteza imbere, gukora no kohereza mu mahanga magnets za neodymium iron boron zikora neza cyane, magnets za neodymium zisanzwe zifite imiterere 47, kuva kuri N33 kugeza kuri 35AH, na GBD Series kuva kuri 48SH kugeza kuri 45AH zirahari. Niba ushishikajwe n'ibicuruzwa byacu, twandikire ubu ngubu!
