Itsva YeMagineti Yepasi? Gallium Inogona Kuve Iyo Eco-Hushamwari Inotsiva Dysprosium uye Terbium?
Munzvimbo yeasingawanzo pasi magineti echigarire, nhaurirano yeshanduko pamusoro pekusimudzira mashandiro uye mashandisirwo ezviwanikwa zviri kuramba zvichiwedzera chinyararire. Sechinyakare, dysprosium uye terbium infiltration matekiniki akashandiswa zvakanyanya kusimbisa kumanikidza uye demagnetization kuramba kweneodymium-iron-boron (NdFeB) magineti. Nekudaro, kucherwa kwezvinhu izvi zvinorema zvisingaite zvepasi zvinounza matambudziko makuru, anosanganisira kudhura kwakanyanya, kukanganisa kwezvakatipoteredza, kushomeka kwekuchengetedza, uye mitengo yakaderera yekushandisa. Takatarisana nenyaya dzinonetsa idzi, kutsvaga dzimwe nzira dzinoshanda uye dzine hushamwari kwezvakatipoteredza kwave kudiwa kukuru mukati meindasitiri.
Zvinoenderana nekuvandudzwa kwazvino, muna 2023, makurukota enyika nemakomisheni vakadaidzira misangano yakawanda kuti vatarise mashandisirwo akanaka ezviwanikwa zvepasi uye kuchengetedza kwezvakatipoteredza, vachinyatso tsanangura gwara rekudzikisa kushandiswa kwezvinhu zvinorema zvisingawanzoitiki. Muchirevo chechinyorwa chino, chimwe chinhu chinonzi gallium chakauya zvishoma nezvishoma mukutarisisa kwevaongorori nevemaindasitiri nekuda kwechimiro chayo chakasiyana uye matura akawanda.\
Gallium: A New Beacon for Rare Earth Magnets?
Gallium, iyo inoratidzawo yakasarudzika tembiricha kuramba uye demagnetization kuramba, inozvirumbidza yakaderera zvakanyanya mutengo wemusika pane terbium uye mutengo wakaderera zvishoma pane dysprosium, ichipa yakanakira hupfumi mukana. Chinonyanya kukosha ndechekuti gallium's total mineral reserves inodarika iyo dysprosium uye terbium, zvichigadzira nzira yekushandiswa kukuru. Sezvo Bazi reIndasitiri neRuzivo rweTekinoroji rinokurudzira "kuchengetedza simba, kudzikisira kuburitsa, uye kusimudzira kwakasimba kweinjiniya yemagetsi emagetsi," kuita kwepamusoro uye hupenyu hurefu hwemagineti asingawanzo magumo epasi zvave zvakakosha kuindasitiri itsva yemagetsi. Mitemo inotaura kuti demagnetization rate yeasingawanzo pasi magineti echigarire inofanirwa kudzorwa mukati me1% mukati memakore gumi anotevera, ichiisa zvakaomesesa zvinodiwa pakusarudzwa kwezvinhu uye kushandisa.
The Post-Permanent Magnet Era: Gallium Inogona Kutungamirira Trend
Zvichipesana nemamiriro ezvinhu aya, gallium, ine zvimiro zvayo zvakasiyana uye zviwanikwa zvekushandisa, iri kurumbidzwa sechinhu chakakosha chinotsiva chinyakare chepasi zvinhu senge dysprosium uye terbium. Shanduko iyi ine vimbiso yekudzikisa kushomeka kwezviwanikwa zvepasi zvisingawanzo, kuderedza kusvibiswa kwezvakatipoteredza panguva yekuchera migodhi, uye kupa mamwe ehupfumi uye eco-hushamwari mhinduro kuindasitiri itsva yemagetsi emagetsi. Nyanzvi dzemaindasitiri dzinokurudzira kuti nekuenderera mberi kwehunyanzvi hwekuita uye akawedzera mamiriro ekushandisa, kushandiswa kwegallium mune isingawanzo gineti yepasi magineti inobata mukana wakakura, ungangounza nguva nyowani yekuvandudza zvinhu.
Mhedziso
Kutarisana nematambudziko maviri ekushomeka kwezviwanikwa zvepasirese uye kuchengetedza kwezvakatipoteredza, hunyanzvi uye kuvandudzwa kwezvinhu zvisingawanzo zvepasi zvinotakura mabasa akakosha. Kubuda kwegallium sechisarudzo chinoshanda kunopinza hunyoro hutsva uye tariro mundima iyi. Mune ramangwana, isu tinotarisira neshungu zvakawanda zvakabudirira kubudirira kwekushandisa gallium, pamwe chete kusimudzira iyo isingawanzo indasitiri yezvigadzirwa zvepasi kune nzira yakasvibira, inoshanda, uye inoenderera.
