Ngā Auahatanga i roto i te Hangarau Neodymium Magnet

Kua hurihia e ngā aukume Neodymium (NdFeB)—ngā aukume tuturu kaha rawa atu o te Ao—ngā ahumahi mai i te pūngao ma ki ngā hikohiko kaihoko. Engari i te pikinga ake o te tono mō ngā waka hiko (EV), ngā tāhū hau, me ngā mahi karetao matatau, ka pāngia ngā aukume NdFeB tuku iho e ngā wero: te whakawhirinaki ki ngā huānga whenua-onge onge (REE), ngā herenga mahi i roto i ngā āhuatanga tino kino, me ngā āwangawanga taiao.

Whakauruhia te mea houngā auahatanga i roto i te hangarau aukume neodymium. Mai i ngā putanga hou o te pūtaiao rauemi ki te hanga hangarau-a-ringa, kei te hurihia e ēnei whanaketanga te āhua o tā tātou hoahoa, whakaputa, me te whakatinana i ēnei wāhanga nui. Ka tūhuratia e tēnei tuhinga ngā putanga hou me ō rātou pūmanawa ki te whakateretere i te whakawhiti matomato.

1. Te Whakaiti i te Whakawhirinakitanga ki te Whenua Onge

Raruraru: Ko te dysprosium me te terbium—he mea nui mō te pumau o te pāmahana tiketike—he utu nui, he onge, ā, he mōrearea hoki i te taha tōrangapū (90% i ahu mai i Haina).

Ngā Auahatanga:

• Ngā Aukume Kore-Disprosium:

I whakawhanakehia e Toyota me Daido Steel tētahite horapa o te rohe wititukanga, pania ngā aukume ki te dysprosium i ngā wāhi e pāngia ana e te ahotea anake. Ka whakaitihia e tēnei te whakamahinga o te dysprosium mā te 50% me te pupuri tonu i te mahi.

• Ngā Koranu Cerium Mahi-Teitei:

I whakakapia e ngā kairangahau i Oak Ridge National Lab te neodymium ki te cerium (he REE nui ake) i roto i ngā aukume ranu, ā, i tutuki ai80% o te kaha tuku ihoi te haurua o te utu.

 

2. Te Whakarei Ake i te Ātete ki te Pāmahana

Raru: Ka heke te kaha o ngā aukume NdFeB paerewa i runga ake i te 80°C, ka whakawhāiti i te whakamahinga i roto i ngā motuka EV me ngā mīhini ahumahi.

Ngā Auahatanga:

• Ngā Aukume HiTREX:

Hitachi Metals'HiTREXe mahi ana te raupapa i200°C+ mā te arotau i te hanganga o te witi me te tāpiri i te cobalt. Ka whakakahangia e ēnei aukume ngā motuka Tauira 3 a Tesla, ka taea ai te tawhiti ake me te tere ake o te whakaterenga.

• Te Hanganga Tāpiri:

Ngā aukume tā-3D mengā hanganga whatunga nanote tuku wera kia pai ake te whai hua, me te whakapai ake i te pumau o te wera mā te30%.

 

3. Te Whakaputa me te Hangarua Tauwhiro

Raru: Ka puta he para paitini mai i ngā REE keri; iti iho i te 1% o ngā aukume NdFeB ka hangarua.

Ngā Auahatanga:

• Te Hangarua Hauwai (HPMS):

Ngā whakamahinga a HyProMag nō te UKTe Tukatuka Hauwai o te Para Aukume (HPMS) ki te tango me te tukatuka anō i ngā aukume mai i ngā para hiko me te kore e ngaro te kounga. Ka whakaitihia e tēnei tikanga te whakamahinga pūngao mā te90%vs. te keri tuku iho.

• Te Whakamahinga Kakariki:

He kamupene pēnei i a Noveon Magnetics e whakamahi ana i ngāngā tukanga hikohiko kore-whakarewa hei whakapai ake i ngā REE, hei whakakore i ngā para waikawa me te whakaiti i te whakamahinga wai mā te70%.

 

4. Te Whakaiti me te Tika

Raru: Ko ngā taputapu kiato (hei tauira, ngā taputapu mau, ngā waka rererangi kore) e hiahia ana ki ngā aukume iti ake, kaha ake.

Ngā Auahatanga:

• Ngā Aukume Herea:

Mā te whakaranu i te paura NdFeB me ngā pūmua ka hangaia he aukume tino angiangi, ngāwari hoki mō ngā AirPods me ngā whakaurunga hauora. Ka tutuki i ngā aukume here a Magnequench40% teitei ake te rerenga aukumei roto i ngā matotoru iti iho i te mirimita.

• Ngā Hoahoa Arotau-AI:

Ka whakamahia e Siemens te ako mīhini hei whakatauira i ngā āhua aukume mō te tino whai huatanga. Nā ā rātou aukume rotor i hoahoa AI i whakanui ake te putanga o te hau tāpoi mā te15%.

5. Ātete ki te Waikura me te Roa o te Ora
Raru: Ka waikura ngāwari ngā aukume NdFeB i ngā taiao makuku, waikawa rānei.

Ngā Auahatanga:

• Paninga Waro Rite-Taimana (DLC):

He kamupene hou nō Hapani e whakaki ana i ngā aukume kiDLC—he paparanga angiangi, tino mārō—e whakaiti ana i te waikura mā te 95% me te iti rawa hoki o te taumaha e tāpiri ana.

• Ngā Pūmua Whakaora-ā-Iho:

I whakauruhia e ngā kairangahau o MIT ngā kāpūru iti o ngā matū whakaora ki roto i ngā paninga aukume. Ina rakurakuhia, ka tukuna e ngā kāpūru he kiriata tiaki, ka roa ake te roa o te ora mā te3x.

 

6. Ngā Taupānga o te Reanga Panuku
Kei te wetewetehia e ngā aukume auaha ngā hangarau o mua:

 

• Whakamatao Aukume:

Ka whakakapia ngā hau whakamatao hau kati kōtuhi e ngā pūnaha aukume e whakamahi ana i ngā koranu NdFeB. Ka whakaitihia e ngā pouaka whakamatao aukume a Cooltech Applications te whakamahinga pūngao mā te40%.

• Te Utu Ahokore:

Ka whakamahia e MagSafe a Apple ngā rarangi NdFeB nano-crystalline mō te whakahāngaitanga tika, e tutuki ai75% te tere o te utui ngā koiri tuku iho.

• Rorohiko Kuantum:

Mā ngā aukume NdFeB tino pumau ka taea te whakahaere tika i ngā qubit i roto i ngā tukatuka irahiko, he arotahi matua tēnei mā IBM me Google.

 

Ngā Wero me ngā Aronga o te Ao

Ahakoa te nui o ngā mahi auaha, kei te mau tonu ngā arai:

• Utu:He nui tonu te utu mō ngā tikanga matatau pēnei i te HPMS me te hoahoa AI hei whakamahi mā te marea.
• Te Whakapūmautanga:Kāore i te whai hanganga ā-ao mō te kohikohi me te tukatuka i ngā pūnaha hangarua.

Te Huarahi kei mua:

1. Ngā Mekameka Tukunga Porowhita-Katia:Ko ngā kaihanga waka pēnei i a BMW e whai ana ki te whakamahi100% hangaruangā aukume i te tau 2030.
2. Ngā Aukume e Hangai ana ki te Koiora:Kei te whakamātautau ngā kairangahau i ngā huakita hei tango i ngā REE mai i te wai para.
3. Te Keritanga Ātea:Ahakoa he whakapae tonu tēnei, kei te tūhuratia e ngā kamupene hou pēnei i a AstroForge te keri asteroid mō ngā whenua onge.

Whakamutunga: Ngā Aukume mō te Ao Kakariki, Atamai Ake

Ehara i te mea ko ngā hua kaha ake, iti ake rānei ngā mahi auaha i roto i te hangarau aukume neodymium anake—engari ko te whakaaro anō ki te oranga tonutanga. Mā te whakaiti i te whakawhirinaki ki ngā rauemi iti, te whakaiti i ngā tukunga, me te whakahohe i ngā putanga hou i roto i te pūngao ma me te rorohiko, he mea nui ēnei whanaketanga ki te whakatutuki i ngā whāinga āhuarangi o te ao.

Mō ngā pakihi, ko te noho ki mua ko te mahi tahi me ngā kaihanga auaha me te haumi ki te R&D. Mō ngā kaihoko, he whakamaumaharatanga tēnei ahakoa te aukume iti rawa ka taea te whai pānga nui ki te heke mai o tō tātou ao.
