Imashini ya Neodymium (Nd-Fe-B)ni isi isanzwe idasanzwe igizwe na neodymium (Nd), icyuma (Fe), boron (B), hamwe nicyuma cyinzibacyuho.Bafite imikorere isumba iyindi mubikorwa kubera imbaraga zabo zikomeye za magnetique, arizo 1.4 teslas (T), igice cya induction ya magnetique cyangwa flux density.
Imashini ya Neodymium yashyizwe mu byiciro nuburyo ikorwa, igacumura cyangwa igahuzwa.Babaye benshi bakoreshwa na magnesi kuva bakura mu 1984.
Muburyo busanzwe, neodymium ni ferromagnetic kandi irashobora gukoreshwa gusa mubushyuhe buke cyane.Iyo ihujwe nibindi byuma, nkicyuma, irashobora gukwega ubushyuhe bwicyumba.
Ubushobozi bwa magnetique ya magneti ya neodymium irashobora kugaragara mwishusho iburyo.
Ubwoko bubiri bwa magneti yisi idasanzwe ni neodymium na samarium cobalt.Mbere yo kuvumbura magnesi ya neodymium, magneti ya samarium cobalt niyo yakoreshwaga cyane ariko yasimbujwe na magneti neodymium kubera amafaranga yo gukora samarium cobalt.
Nibihe Byiza bya Magneti ya Neodymium?
Ikintu nyamukuru kiranga magnesi ya neodymium nuburyo bukomeye kubunini bwayo.Umwanya wa magneti wa magneti ya neodymium ubaho iyo umurima wa magneti ushyizwemo hamwe na dipole ya atome igahuza, aribwo buryo bwa magnetiki hystereze.Iyo umurima wa rukuruzi ukuweho, igice cyo guhuza kiguma muri neodymium ya magneti.
Urwego rwa neodymium rukuruzi rwerekana imbaraga za rukuruzi.Umubare munini wamanota, imbaraga za rukuruzi.Imibare iva mumitungo yabo yerekanwe nka mega gauss Oersteds cyangwa MGOe, niyo ngingo ikomeye ya BH Curve yayo.
Igipimo cya "N" gitangirira kuri N30 kikajya kuri N52, nubwo N52 magnet zikoreshwa gake cyangwa zikoreshwa gusa mubihe bidasanzwe.Umubare "N" urashobora gukurikirwa ninyuguti ebyiri, nka SH, zerekana imbaraga za rukuruzi (Hc).Iyo Hc iri hejuru, nubushyuhe bwa neo magnet irashobora kwihanganira mbere yo gutakaza umusaruro.
Imbonerahamwe ikurikira irerekana urutonde rusanzwe rwa magneti ya neodymium ikoreshwa muri iki gihe.
Ibyiza bya Magneti ya Neodymium
Igisubizo:
Iyo neodymium ishyizwe mumashanyarazi, dipole ya atome irahuza.Nyuma yo gukurwa mumurima, igice cyo guhuza gikomeza gukora neodimium ya magneti.Igisigisigi nubucucike bwa flux bugumaho mugihe umurima wo hanze ugarutse kuva ku giciro cyuzuye kuri zeru, aribwo magnetisime isigaye.Iyo hejuru ya remanence, niko flux yuzuye.Imashini ya Neodymium ifite ubwinshi bwa 1.0 kugeza 1.4 T.
Imikorere ya magneti ya neodymium iratandukanye bitewe nuburyo yakozwe.Magneteri ya neodymium ifite T ya 1.0 kugeza 1.4.Imashini ya neodymium ihujwe ifite 0,6 kugeza 0.7 T.
Guhatira:
Nyuma ya neodymium imaze gukwega, ntabwo isubira kuri magnetisiyumu.Kugirango isubire kuri zeru ya zeru, igomba gusubizwa inyuma numurima muburyo bunyuranye, ibyo bita agahato.Uyu mutungo wa rukuruzi nubushobozi bwarwo bwo guhangana ningaruka zingufu za rukuruzi zo hanze utarinze kwaduka.Guhatira ni igipimo cy'uburemere bukenewe kuva mu murima wa magneti kugirango ugabanye rukuruzi ya magneti isubira kuri zeru cyangwa kurwanya imbaraga za rukuruzi kugirango ziveho.
Guhatira gupimwa mubice bya oersted cyangwa ampere yanditseho Hc.Guhatira magneti ya neodymium biterwa nuburyo byakozwe.Imashini ya neodymium yacumuye ifite imbaraga za 750 Hc kugeza 2000 Hc, mugihe magneti ya neodymium ihujwe ifite ingufu za 600 Hc kugeza 1200 Hc.
Ibicuruzwa bitanga ingufu:
Ubucucike bwingufu za rukuruzi burangwa nagaciro ntarengwa k'ubucucike bwikubye inshuro imbaraga za magnetiki yumurima, niwo mubare wa magnetiki flux kuri buri gice cyubuso.Ibice bipimirwa muri teslas kubice bya SI hamwe na Gauss yacyo hamwe nikimenyetso cyubwinshi bwa flux ni B. Ubwinshi bwa Magnetic flux ubwinshi nigiteranyo cyumurima wa magnetiki wo hanze H hamwe na magnetiki yumubiri wa magnetiki polarisiyasi J mubice bya SI.
Imashini zihoraho zifite B umurima wibanze hamwe nibidukikije.Icyerekezo cyimbaraga za B cyitirirwa ingingo imbere no hanze ya magneti.Urushinge rwa compasse muri B umurima wa rukuruzi rwerekana icyerekezo cyumurima.
Nta buryo bworoshye bwo kubara flux ubwinshi bwimiterere ya magneti.Hano hari porogaramu za mudasobwa zishobora kubara.Inzira yoroshye irashobora gukoreshwa kuri geometrike itoroshye.
Ubukomezi bwumurima wa magneti bupimirwa muri Gauss cyangwa Teslas kandi ni igipimo rusange cyimbaraga za rukuruzi, ni igipimo cyubucucike bwumurima wa rukuruzi.Imetero ya gauss ikoreshwa mugupima ubunini bwa magneti.Ubucucike bwa flux kuri magneti ya neodymium ni 6000 Gauss cyangwa munsi yayo kuko ifite umurongo ugororotse demagnetisation.
Ubushyuhe bwa Curie:
Ubushyuhe bwa curie, cyangwa ingingo ya curie, nubushuhe ibikoresho bya magneti bigira impinduka mumiterere ya magnetique bigahinduka paramagnetic.Mu byuma bya magneti, atome ya magneti ihujwe mu cyerekezo kimwe kandi igashimangira umurima wa rukuruzi.Kuzamura ubushyuhe bwa curie bihindura gahunda ya atome.
Guhatira kwiyongera uko ubushyuhe bwiyongera.Nubwo magnesi ya neodymium ifite imbaraga nyinshi mubushyuhe bwicyumba, iramanuka uko ubushyuhe buzamuka kugeza bugeze ku bushyuhe bwa curie, bushobora kuba hafi 320 ° C cyangwa 608 ° F.
Hatitawe ku kuntu magnesi ya neodymium ishobora kuba ikomeye, ubushyuhe bukabije burashobora guhindura atome zabo.Kumara igihe kinini ubushyuhe bwo hejuru birashobora gutuma batakaza burundu imiterere ya rukuruzi, itangirira kuri 80 ° C cyangwa 176 ° F.
Nigute Magnets ya Neodymium ikorwa?
Inzira ebyiri zikoreshwa mugukora magnesi ya neodymium zirimo gucumura no guhuza.Imiterere ya magneti yarangiye iratandukanye bitewe nuburyo ikorwa hamwe no gucumura bikaba byiza muburyo bubiri.

-
Gukoresha rukuruzi:
Nubwo rukuruzi rufite icyerekezo cya magnetisiyonike, ntabwo rukoreshwa kandi rugomba guhura nigihe gito mumashanyarazi akomeye, akaba ari agapira k'insinga kuzengurutse rukuruzi.Magnetizing ikubiyemo capacator na voltage nyinshi kugirango bitange ingufu zikomeye.
-
Igenzura rya nyuma:
Imishinga yo gupima digitale igenzura ibipimo na tekinoroji ya x-ray fluorescence igenzura ubunini bwisahani.Ipitingi igeragezwa mubundi buryo kugirango irebe ubwiza n'imbaraga zayo.BH umurongo ugeragezwa nigishushanyo cya hystereze kugirango hemezwe gukura kwuzuye.
Guhuza
Guhambira, cyangwa guhuzagurika, ni inzira yo gupfa ikoresha uruvange rw'ifu ya neodymium hamwe na epoxy binding agent.Uruvange ni 97% ibikoresho bya magnetiki na 3% epoxy.
Imvange ya epoxy na neodymium ihagarikwa mu icapiro cyangwa igasohoka igakira mu ziko.Kubera ko imvange ikanda mu rupfu cyangwa igashyirwa mu gusohora, magnesi zirashobora kubumbabumbwa muburyo bugoye.Guhuza compression inzira itanga magnesi hamwe no kwihanganira gukomeye kandi ntibisaba ibikorwa bya kabiri.
Kwiyunvira guhuza magnesi ni isotropic kandi irashobora gukoreshwa muburyo ubwo aribwo bwose, burimo ibice byinshi bya polar.Guhuza epoxy ituma magnesi akomera bihagije kugirango asya cyangwa yegeranye ariko ntagucukurwa cyangwa gukoreshwa.
Imirasire
Imiyoboro ya neodymium yerekanwe cyane ni magneti mashya ku isoko rya magneti.Inzira yo gukora radiyo ihujwe na magnet irazwi imyaka myinshi ariko ntabwo yakoreshejwe neza.Iterambere rya tekinoloji ya vuba ryahinduye inzira yo gukora bigatuma magneti yerekanwe kumurongo byoroshye kubyara umusaruro.
Inzira eshatu zo gukora radiyo ihuza neodymium magneti ni anisotropique yumuvuduko ukabije, gushyushya gukanda inyuma, hamwe no guhinduranya umurima.
Inzira yo gucumura yemeza ko nta mwanya ufite intege nke muburyo bwa magneti.
Ubwiza budasanzwe bwa magneti buhujwe ni icyerekezo cyumurima wa magneti, ugenda uzenguruka kuri perimetero ya rukuruzi.Inkingi yepfo ya magneti iri imbere yimpeta, mugihe inkingi yo mumajyaruguru iri muruziga.
Imashini ya neodymium yerekanwe cyane ni anisotropique kandi ikoreshwa na magneti kuva imbere yimpeta kugeza hanze.Imirasire ya radiyo yongerera imbaraga imbaraga za rukuruzi kandi irashobora gushushanywa muburyo bwinshi.
Imirasire ya radiyo neodymium irashobora gukoreshwa kuri moteri ikomatanya, moteri ikandagira, na moteri ya DC idafite amashanyarazi kubinyabiziga, mudasobwa, ibikoresho bya elegitoroniki, n’itumanaho.
Porogaramu ya Neodymium Magnets
Abashinzwe Gutandukanya Magneti:
Mu myiyerekano ikurikira, umukandara wa convoyeur utwikiriwe na magnesi ya neodymium.Imashini zitondekanye hamwe nizindi zisimburana zireba hanze zibaha imbaraga za rukuruzi.Ibintu bidakwega magnesi biragwa, mugihe ibikoresho bya ferromagnetiki bijugunywa mumasanduku.
