Itondekanya rya Magneti ya Neodymium
Ukurikije uburyo bwo gukora bukoreshwa, Neodymium Magnet ibikoresho birashobora kugabanywamoIcyaha NeodymiumnaBonded Neodymium. Bonded Neodymium ifite magnetisme mu mpande zose kandi irwanya ruswa; Neodymium yacumuye ikunda kwangirika kandi irasabagutwikiraku buso bwarwo, muri rusange harimo isahani ya zinc, isahani ya nikel, ibidukikije byangiza ibidukikije, isahani yangiza ibidukikije, nikel y'umuringa wa nikel, isahani yangiza ibidukikije nikel, nikindi.Porogaramumubicuruzwa bigezweho bikenera magnesi zikomeye zihoraho, nka moteri yamashanyarazi mubikoresho bitagira umugozi, disiki ya disiki ikomeye, hamwe na rukuruzi ya magneti, bafashe umwanya wubundi bwoko bwa magneti.
Ubwoko busanzwe bwa Magnetike-Isi ni aNeodymium Magnet, bikunze kuvugwa nka aNdFeB, NIB, cyangwa Neo magnet. Neodymium, Iron, na Boron byahujwe no gukora Magnet ya Permanent ya Nd2Fe14B ya tetragonal kristaline. Imashini ya Neodymium nubwoko bukomeye bwa Magneti ihoraho kurubu. Byakozwe mu buryo butandukanye mu 1984 na General Motors na Sumitomo Metals idasanzwe.
Neodymium Magnetni ibintu bigoye cyane bivunika bifite ubucucike buke ariko bifite imashini nini cyane, kandi igiciro cyacyo cyo hasi kiri munsi yizindi mibare idasanzwe ya Magnetique. Kugeza ubu, hashingiwe ku kugereranya gutambuka kugabana ku isoko hamwe n’ibisekuru bya gatatu Rare Earth Permanent Magnet Materials, Neodymium Magnets ifite umugabane mwinshi ku isoko n’umusaruro w’umwaka, gusa munsi yahendutseMagnite ya Ferrite.
Magnette NdFeBzifite imiterere ihanitse ya magnetique kandi ikoreshwa mubice byinshi, harimo inzugi zumuryango, moteri, moteri, hamwe ninganda zikomeye.
Imashini ifunzezirakomeye kuruta inshinge zakozwe.
Injiza ya plastike NdFeBni igisekuru gishya cyibikoresho bigizwe nifu ya magnetiki ihoraho hamwe na plastiki, hamwe nibintu bidasanzwe bya magnetiki na plastike, kimwe nukuri kandi birwanya guhangayika.
Imashini ya Neodymium
Icuma cya Neodymium Magnetni rukuruzi rukomeye muri iki gihe, rudafite gusa ibiranga ibintu byiza cyane nka remanence yo hejuru, guhatira cyane, ingufu za magneti nyinshi, hamwe nigiciro cyibiciro byinshi ariko nanone biroroshye gutunganyirizwa muburyo butandukanye, cyane cyane bikwiranye nimbaraga nyinshi kandi imirima miremire yumurima, kimwe nibicuruzwa bitandukanye byoroheje kandi byoroheje.
Magnets ya Neodymium ikoreshwa cyane cyane mumodoka (gutwara amashanyarazi, kuyobora amashanyarazi, sensor, nibindi), kubyara ingufu z'umuyaga, inganda zamakuru (disiki zikomeye, disiki ya optique), ibikoresho bya elegitoroniki (terefone igendanwa, kamera ya digitale), murugo ibikoresho (impinduka zumuyaga uhindagurika, firigo, hamwe nimashini zo kumesa), moteri yumurongo wa moteri, moteri yerekana amashusho ya magnetiki resonance, nibindi.Porogaramumubice nka serivisi zubwenge ziragenda ziyongera.
Amashanyarazi ya Neodymium
Bonded Neodymium Magnet ni ubwoko bwibikoresho bya magneti bihoraho bikozwe muguhuza nanocrystalline neodymium icyuma cya boron magnetic ifu ya polymer hamwe na polymer ndende (nka thermosetting epoxy resin, plastike yubuhanga bwa termoplastique, nibindi) nkumuhuza, ugabanijwemo kabiri.Bonded Neodymium Yasunitswe na MagnetinaImashini ya Neodymium yatewe. Ifite uburebure buhanitse cyane, uburinganire bwiza bwa magnetique, hamwe no guhuzagurika, kandi birashobora gukorwa muburyo bugoye bigoye kugerwaho kuri magneti ya neodymium yacumuye kandi byoroshye guhuza nibindi byuma cyangwa plastike kugirango bibeho. Magnets ya Neodymium ifite kandi uburyo butandukanye bwa magnetisiyonike, gutakaza eddy nkeya, hamwe no kurwanya ruswa.
Magnets ya Neodymium ikoreshwa cyane cyane mubikorwa byikoranabuhanga byikoranabuhanga nka mudasobwa igendanwa ya mudasobwa na moteri ya optique ya moteri ya moteri, printer / kopi ya moteri, hamwe na rukuruzi ya magnetiki, hamwe no gutwara no kugenzura ibikoresho bikoreshwa mu rugo bikoresha ingufu zikoresha ibikoresho byo mu rugo hamwe na elegitoroniki y’abaguzi. Gukoresha kwabo muri moteri na moteri idasanzwe hamwe na sensor yimodoka nshya yingufu bigenda bihinduka isoko nyamukuru igaragara.
Ibisobanuro byimbaraga
Neodymium ni icyuma cya antifiromagnetiki cyerekana ibimenyetso bya magneti iyo cyera, ariko ku bushyuhe buri munsi ya 19 K (254.2 ° C; 425.5 ° F). Ibikoresho bya Neodymium hamwe na ferromagnetic yinzibacyuho nkicyuma, ifite ubushyuhe bwa Curie hejuru yubushyuhe bwicyumba, bikoreshwa mugukora magneti ya neodymium.
Imbaraga za Neodymium imbaraga ni ihuriro ryibintu bitandukanye. Ikigaragara cyane ni magnetocrystalline anisotropy yo hejuru cyane ya anisotropy ya tetragonal Nd2Fe14B ya kirisiti ya kirisitu (HA 7 T - imbaraga zumurima wa H mubice bya A / m kurwanya ibihe bya magneti muri Am2). Ibi byerekana ko kristu yibintu ikwirakwiza cyane kumurongo runaka wa kirisiti ariko ugasanga bigoye cyane gukanda mubindi byerekezo. Imisemburo ya neodymium, kimwe nizindi magneti, ikozwe mu binyampeke bya microcrystalline biri mu gihe cyo gukora bihujwe mu murima ukomeye wa rukuruzi ku buryo amashoka ya magneti yose yerekeza mu cyerekezo kimwe. Uru ruganda rufite imbaraga nyinshi cyane, cyangwa kurwanya demagnetisation, bitewe na kasitori ya kirisiti yo kurwanya icyerekezo cya magnetisme.
Kuberako irimo electron enye zidakorewe muburyo bwa electron ugereranije na (ugereranije) eshatu mubyuma, atome ya neodymium irashobora kugira umwanya wa magneti dipole ikomeye. Electron idakorewe muri magneti ihujwe kuburyo kuzunguruka kwabo kwerekeje icyerekezo kimwe bitanga umurima wa rukuruzi. Ibi bivamo imbaraga zo kwiyuzuzamo gukomeye kwa Nd2Fe14B (Js 1.6 T cyangwa 16 kG) hamwe na magnetisike isigaye ya 1.3 teslas. Nkigisubizo, iki cyiciro cya magneti gifite ubushobozi bwo kubika ingufu nyinshi za magneti (BHmax 512 kJ / m3 cyangwa 64 MGOe), kuko ubwinshi bwingufu zingana na Js2.
Ingufu za rukuruzi zifite agaciro kangana ninshuro 18 nubunini ninshuro 12 kubwinshi kuruta "ibisanzwe"ferrite. Cobalt ya Samarium (SmCo), icya mbere kiboneka mubucuruzi budasanzwe-isi, ifite urwego rwo hasi rwingufu za rukuruzi kuruta NdFeB alloys. Imiterere ya magneti ya Neodymium irangwa rwose na microstructure ya alloy, inzira yo gukora, hamwe nibigize.
Atome yicyuma hamwe na neodymium-boron ikomatanya iboneka mubindi bisimburana imbere ya Nd2Fe14B. Atom ya diamagnetic boron itera ubumwe binyuze mumigozi ikomeye ya covalent ariko ntabwo itanga umusanzu muburyo bwa magnetisme. Imashini ya Neodymium ihenze cyane kuruta samariyumu-cobalt bitewe na metero nkeya ugereranije n’ubutaka (12% ku bunini, 26.7% na misa), hamwe no kubona neodymium na fer ugereranije na samarium na cobalt.

Mubintu byingenzi biranga ikoreshwa mu gutandukanya magnesi zihoraho harimo:
Gusigara(Br),igereranya imbaraga za rukuruzi.
Guhatirwa(Hci),demagnetisation irwanya ibikoresho.
Igicuruzwa ntarengwa(BHmax),agaciro gakomeye ka magnetiki flux yuzuye (B) inshuro
imbaraga za magnetique imbaraga, zipima ubucucike bwingufu za magneti (H).
Ubushyuhe bwa Curie (TC), ingingo aho ikintu kireka kuba magnetique.
Imashini ya Neodymium iruta ubundi bwoko bwa magneti mubijyanye na remanence, agahato, nibicuruzwa bitanga ingufu, ariko akenshi bifite ubushyuhe buke bwa Curie. Terbium na dysprosium nibintu bibiri bidasanzwe bya neodymium magnet alloys byakozwe hamwe nubushyuhe bwo hejuru bwa Curie no kwihanganira ubushyuhe bwinshi. Imikorere ya magneti ya Neodymium itandukanye nubundi bwoko bwa magneti buhoraho mumeza hepfo.

Ibibazo bya Ruswa
Imipaka yintete ya magneti yacumuye irashobora kwibasirwa cyane na Nd2Fe14B. Ubu bwoko bwa ruswa bushobora kuvamo kwangirika gukomeye, nko gutemba hejuru yubuso cyangwa gusenyuka kwa rukuruzi mu ifu ya uduce duto duto twa magneti.
Ibicuruzwa byinshi byubucuruzi bikemura iki kibazo ushizemo igifuniko cyo gukingira kugirango uhagarike ibidukikije. Isahani ikunze kugaragara ni nikel, nikel-umuringa-nikel, na zinc, mugihe ibindi byuma nabyo bishobora gukoreshwa, kimwe na polymer na lacquer birindaimpuzu.
Ingaruka z'ubushyuhe
Neodymium ifite coefficient itari nziza, bivuze ko iyo ubushyuhe buzamutse, haba ku gahato ndetse n’ubucucike bukabije bwa magneti (BHmax) bugabanuka. Ku bushyuhe bw’ibidukikije, magnesi ya neodymium-fer-boron ifite imbaraga nyinshi; ariko, iyo ubushyuhe bwiyongereye hejuru ya 100 ° C (212 ° F), agahato kagabanuka vuba kugeza kageze ku bushyuhe bwa Curie, buri hagati ya 320 ° C cyangwa 608 ° F. Uku kugabanuka kwagahato kugabanya imbaraga za magneti mubikorwa byubushyuhe bwo hejuru nka turbine yumuyaga, moteri ya Hybrid, nibindi. Kugirango wirinde imikorere igabanuka kubera ihindagurika ryubushyuhe, terbium (Tb) cyangwa dysprosium (Dy) hiyongereyeho, byongera ikiguzi cya rukuruzi.
