Ubuchwepheshe be-Neodymium Magnet

Amamagnethi e-Neodymium (NdFeB)—amamagnethi aqinile kakhulu emhlabeni—aguqule izimboni kusukela kumandla ahlanzekile kuya kuma-electronics abathengi. Kodwa njengoba isidingo sikhula ngesivinini sezimoto zikagesi (ama-EV), ama-wind turbine, namarobhothi athuthukile, amamagnethi endabuko e-NdFeB abhekene nezinselele: ukuthembela ezintweni ezingavamile zomhlaba (ama-REE), imikhawulo yokusebenza ezimweni ezimbi kakhulu, kanye nokukhathazeka ngemvelo.

Ngena emkhakheni ophambiliukusungula izinto ezintsha kubuchwepheshe be-neodymium magnet. Kusukela ekuthuthukisweni kwesayensi yezinto ezibonakalayo kuya ekukhiqizweni okuqhutshwa yi-AI, lokhu kuthuthuka kushintsha indlela esiklama, sikhiqize futhi sisebenzise ngayo lezi zingxenye ezibalulekile. Le bhulogi ihlola ukuthuthuka kwakamuva kanye nekhono lazo lokusheshisa ushintsho oluhlaza.

1. Ukunciphisa Ukuthembela Emhlabeni Ongavamile

Inkinga: I-Dysprosium kanye ne-terbium—ezibalulekile ekuzinzeni kwezinga lokushisa eliphezulu—zibiza kakhulu, ziyivelakancane, futhi ziyingozi ngokwendawo kwezepolitiki (90% zivela eShayina).

Izinto ezintsha:

3. Ukukhiqizwa Okuqhubekayo Nokusetshenziswa Kabusha

Inkinga: Ukumbiwa kwe-REE kukhiqiza imfucuza enobuthi; ngaphansi kuka-1% wamagnethi e-NdFeB aphinde asetshenziswe.

Izinto ezintsha:

• Ukuvuselelwa kwe-Hydrogen (HPMS):

Ukusetshenziswa kwe-HyProMag ese-UKUkucutshungulwa kwe-Hydrogen kwe-Magnet Scrap (HPMS) ukukhipha nokucubungula kabusha omazibuthe kusuka ku-e-waste ngaphandle kokulahlekelwa yikhwalithi. Le ndlela inciphisa ukusetshenziswa kwamandla ngo90%uma kuqhathaniswa nokumba kwendabuko.

• Ukucwengisisa Okuluhlaza:

Izinkampani ezifana neNoveon Magnetics ziyaqashaizinqubo ze-electrochemical ezingenayo i-solvent ukucwenga ama-REE, ukuqeda imfucuza ye-asidi kanye nokunciphisa ukusetshenziswa kwamanzi70%.

 

4. Ukwenziwa Kancane Nokunemba

Inkinga: Amadivayisi amancane (isib., izinto ezigqokwayo, ama-drone) adinga omaginethi abancane nabanamandla.

Izinto ezintsha:

• Omaginethi Abahlanganisiwe:

Ukuxuba i-NdFeB powder nama-polymer kudala omaginethi abancane kakhulu nabaguquguqukayo be-AirPods kanye nezifakelo zezokwelapha. Omaginethi ababoshwe be-Magnequench bayaphumelelaUkuphuma kwamandla kazibuthe okuphezulu ngo-40%ngobukhulu obungaphansi kwamamilimitha.

• Imiklamo Elungiselelwe I-AI:

I-Siemens isebenzisa ukufunda komshini ukulingisa izimo zemagnethi ukuze isebenze kahle kakhulu. Amamagnethi abo e-rotor aklanywe nge-AI andise umkhiqizo we-wind turbine ngo15%.

5. Ukumelana Nokugqwala Nokuphila Isikhathi Eside
Inkinga: Omaginethi be-NdFeB bagqwala kalula ezindaweni ezinomswakama noma ezine-asidi.

Izinto ezintsha:

• Ukwembozwa Kwekhabhoni Elifana Nedayimane (i-DLC):

Inkampani entsha yaseJapan igqoka amagiya ane-magnetsI-DLC—ungqimba oluncane, oluqinile kakhulu—olunciphisa ukugqwala ngo-95% ngenkathi lunezela isisindo esincane.

• Ama-polymers Aziphilisayo:

Abacwaningi be-MIT bafaka ama-microcapsule ezinto zokwelapha ezimbozweni zikamazibuthe. Uma eklwejwa, ama-capsule akhipha ifilimu evikelayo, eyandisa isikhathi sokuphila ngo3x.

 

6. Izicelo zesizukulwane esilandelayo
Omaginethi abasha bavula ubuchwepheshe besikhathi esizayo:

 

• Ukupholisa KukaMazibuthe:

Izinhlelo ze-magnetocaloric ezisebenzisa ama-NdFeB alloys zithatha indawo yeziqandisi zegesi ebamba ukushisa. Iziqandisi ze-magnetic ze-Cooltech Applications zinciphisa ukusetshenziswa kwamandla ngo40%.
