Udushya mu ikoranabuhanga rya Neodymium Magnet

Magneti za Neodymium (NdFeB)—magneti zikomeye cyane ku Isi—zahinduye inganda ziva ku ngufu zisukuye zijya ku bikoresho by'ikoranabuhanga. Ariko uko umubare w'ibinyabiziga bikoresha amashanyarazi wiyongera, turbine z'umuyaga, na roboti zigezweho, magneti za NdFeB zisanzwe zihura n'imbogamizi: kwishingikiriza ku bintu bidasanzwe by'ubutaka (REEs), ubushobozi buke mu mikorere mu bihe bikomeye, n'ibibazo by'ibidukikije.

Injira mu buryo bugezwehoudushya mu ikoranabuhanga rya neodymium magnet. Kuva ku iterambere rya siyansi y'ibikoresho kugeza ku nganda zishingiye ku buhanga bwa AI, iri terambere ririmo kuvugurura uburyo dushushanya, dukora, kandi tugakoresha ibi bice by'ingenzi. Iyi blog irasuzuma iterambere rigezweho n'ubushobozi bwaryo bwo kwihutisha impinduka mu buryo bw'ibidukikije.

1. Kugabanya kwishingikiriza ku bintu bidasanzwe ku isi

Ikibazo: Dysprosium na terbium—ingenzi cyane mu gutuma ubushyuhe buguma neza—birahenze, ni bike, kandi bifite ingaruka mbi ku rwego rwa politiki (90% bikomoka mu Bushinwa).

Udushya:

• Magneti zidafite Dysprosium:

Toyota na Daido Steel bakozegukwirakwira k'umupaka w'inganoUburyo bwo gukora, gusiga imashini zikoresha dysprosium gusa ahantu hashobora gutera stress. Ibi bigabanya ikoreshwa rya dysprosium ho 50% mu gihe bikomeza gukora neza.

• Aloyi za Cerium zikora neza cyane:

Abashakashatsi bo muri Oak Ridge National Lab basimbuje neodymium na cerium (REE nyinshi) mu ruziga rw’imvange, bagera ku ntego80% by'imbaraga gakondoku giciro cya kabiri.

 

2. Kongera Ubushyuhe bwo Kurwanya

Ikibazo: Magneti zisanzwe za NdFeB zitakaza imbaraga zirenze 80°C, bigatuma ikoreshwa ryazo rigabanuka muri moteri za EV n'imashini z'inganda.

Udushya:

• Amakuru ya HiTREX:

Hitachi Metals'HiTREXuruhererekane rukorera kuri200°C+ binyuze mu kunoza imiterere y'ibinyampeke no kongeramo cobalt. Izi magnets ubu zikoresha moteri za Tesla zo mu bwoko bwa Model 3, zigatuma habaho intera ndende no kwihuta.

• Inyongeramusaruro:

Makuneti zacapwe mu buryo bwa 3D zifiteimiterere y'urukuta rwa nanoscalegukwirakwiza ubushyuhe neza, bikongera ubushyuhe buhamye binyuze mu30%.

 

3. Umusaruro urambye no kongera gukoresha ibikoresho

Ikibazo: Ingufu zo mu birombe bya REE zikora imyanda ihumanya; munsi ya 1% bya magneti za NdFeB zikoreshwa mu kongera gukoreshwa.

Udushya:

• Gutunganya Hydrogen (HPMS):

Ikoreshwa rya HyProMag ikorera mu BwongerezaGutunganya Hydrogen ya Magnet Scrap (HPMS) gukura no gutunganya magnets mu myanda y'ikoranabuhanga nta gutakaza ubuziranenge. Ubu buryo bugabanya ikoreshwa ry'ingufu ku90%ugereranije n'ubucukuzi gakondo.

• Gutunganya Icyatsi:

Amasosiyete nka Noveon Magnetics atanga akaziinzira z'amashanyarazi zidafite ibirungo kunonosora REEs, gukuraho imyanda ya aside no kugabanya ikoreshwa ry'amazi binyuze mu70%.

 

4. Gutunganya no gutunganya neza

Ikibazo: Ibikoresho bito (urugero: ibikoresho byambarwa, indege zitagira abapilote) bisaba rukuruzi nto kandi zikomeye.

Udushya:

• Magneti zifatanye:

Kuvanga ifu ya NdFeB na polymeri bitanga rukuruzi zoroshye cyane kandi zoroshye zo gukoresha AirPods na implants zo kwa muganga. Magnequench ifatanye na Magnequench igerahoUbwinshi bw'ingufu za rukuruzi buri hejuru ya 40%mu bunini bwa sub-milimetero.

• Imiterere myiza ya AI:

Siemens ikoresha imashini zigisha kwigana imiterere ya magnet kugira ngo ikore neza cyane. Magnets zabo zakozwe na AI zongereye imbaraga za turbine y'umuyaga binyuze mu15%.

5. Kurwanya ingese no kuramba
Ikibazo: Magnets za NdFeB ziroroha mu buryo bworoshye ahantu hakonje cyangwa hashyushye.

Udushya:

• Igipfukisho gisa n'ikirahure (DLC) cya Diyama:

Isosiyete y'Abayapani ikora amakote ya magnet ifiteDLC—urwego rworoshye kandi rukomeye cyane—rugabanya ingese ku kigero cya 95% mu gihe rwongera uburemere buke.

• Polymers zivura ubwazo:

Abashakashatsi ba MIT bashyizemo utudomo duto tw’imiti ivura mu irangi rya rukuruzi. Iyo tuvungutse, utudomo dusohora agapira karinda umubiri, kakongera igihe cyo kubaho kwatwo.3x.

 

6. Porogaramu zo mu cyiciro gikurikira
Ingufu zigezweho zirimo gufungura ikoranabuhanga ry'ejo hazaza:

 

• Gukonjesha hakoreshejwe magnetique:

Sisitemu za magnetocaloric zikoresha alloys za NdFeB zisimbura firigo zikoresha imyuka ihumanya ikirere. Frigo za Cooltech Applications zigabanya ikoreshwa ry'ingufu kubera40%.

• Gushyushya nta mugozi:

MagSafe ya Apple ikoresha nano-crystalline NdFeB arrays kugira ngo ihuze neza, igera kuGushyushya vuba 75%kurusha imigozi gakondo.

• Kwandika Kwamunikasiyo:

Magnets za NdFeB zihamye cyane zemerera kugenzura neza qubits muri quantum processors, ikintu cy'ingenzi kuri IBM na Google.

 

Imbogamizi n'amabwiriza y'ejo hazaza

Nubwo udushya twinshi, haracyari imbogamizi:

• Ikiguzi:Ubuhanga buhanitse nka HPMS na AI buracyahenze kugira ngo bukoreshwe ku bwinshi.
• Igenamiterere ry'ibipimo ngenderwaho:Uburyo bwo kongera gukoresha ibikoresho byo gusana ibintu nta bikorwa remezo mpuzamahanga byo kubikusanya no kubitunganya.

Inzira Imbere:

1. Imiyoboro y'ibicuruzwa ifunze:Abakora imodoka nka BMW bagamije gukoreshaGusubiramo 100%magneti bitarenze umwaka wa 2030.
2. Amakuru ashingiye ku binyabuzima:Abashakashatsi barimo kugerageza bagiteri kugira ngo bakure REEs mu mazi yanduye.
3. Ubucukuzi bw'Ibintu Bitandukanye:Amasosiyete mato nka AstroForge ashakisha ubucukuzi bw'amabuye y'agaciro aturuka mu kirere aboneka mu buryo budasanzwe, nubwo ibi bigikomeje kuba ibitekerezo bidafite ishingiro.

Umwanzuro: Ingufu zo kurengera isi y’icyatsi kibisi kandi ifite ubwenge

Udushya mu ikoranabuhanga rya neodymium magnet ntabwo ari ibintu bikomeye cyangwa bito gusa—ni ukuvugurura uburyo ibintu biramba. Mu kugabanya kwishingikiriza ku bushobozi buke, kugabanya imyuka ihumanya ikirere, no gutuma habaho iterambere mu ngufu zisukuye no gukoresha mudasobwa, izi ntambwe ni ingenzi mu kugera ku ntego z’isi mu bijyanye n’ikirere.

Ku bigo by’ubucuruzi, gukomeza kuba imbere bivuze gufatanya n’abahanga mu guhanga udushya no gushora imari mu bushakashatsi no guteza imbere. Ku bakiriya, ni ukwibutsa ko n’ingufu ntoya cyane zishobora kugira ingaruka zikomeye ku hazaza h’isi yacu.
