Kuqine kangakanani ukumuncwa kozibuthe abanamandla be-NdFeB?

Kanjani kunamandla yini ukumunca omazibuthe be-NdFeB abanamandla?

NdFeB omazibuthe njengamanje bangozibuthe abanamandla kakhulu unomphela. NdFeB ozibuthe kukhona okwamanje omazibuthe abatholakala kakhulu kwezohwebo. Baziwa ngokuthi yinkosi amandla kazibuthe. Zinezakhiwo eziphakeme kakhulu zikazibuthe kanye nobukhulu bazo umkhiqizo wamandla kazibuthe (BHmax) uphakeme izikhathi ezingaphezu kwezingu-10 kunalowo we i-ferrite. Iphinde ibe yizibuthe zomhlaba ezingavamile ezisetshenziswa kakhulu njengamanje, futhi yona isetshenziswa ezingxenyeni eziningi nasezintweni ezifana nezizibuthe zethu ezivamile ama-motor, ama-disk drive, kanye ne-imaging magnetic resonance.

Okwayo machinability futhi kuhle impela. Izinga lokushisa lokusebenza lingafinyelela ku-200 amadigri Celsius. Ngaphezu kwalokho, ukuthungwa kwayo kunzima, ukusebenza kwayo kuzinzile, futhi inokusebenza okuhle kwezindleko, ngakho-ke ukusetshenziswa kwayo kubanzi kakhulu. Kodwa ngenxa yokusebenza kwayo kwamakhemikhali aqinile, kufanele iphathwe ngengaphezulu enamathela. (Ezifana ne-Zn, i-Ni Plating, i-electrophoresis, i-passivation, njll.).

Okuyinhloko ingxenye yezibuthe ze-NdFeB iyisici esingavamile se-neodymium. Umhlaba ongavamile awunjalo ebizwa ngokuthi umhlaba ongavamile ngenxa yokuhlushwa kwawo okuphansi, kodwa kunzima kakhulu ehlukene kunezinye izinto ezixhunywe ngamabhondi amakhemikhali. Nakuba i- ukukhangwa kazibuthe of NdFeB odonsa kunamandla kakhulu, ngisho namahemuhemu ukuthi Ozibuthe be-NdFeB bangakwazi ukumunca izikhathi ezingama-600 isisindo sabo. Kodwa eqinisweni, lokhu Isitatimende asiphelele, ngoba ukukhanga kazibuthe nakho kuthintwa izimo eziningi ezifana nokuma nebanga. Ngokwesibonelo, for ozibuthe abanobubanzi obufanayo, ukuphakama kukazibuthe, kunamandla amandla okuheha kazibuthe; omazibuthe abanobude obufanayo, abakhudlwana ububanzi, amandla amakhulu okukhanga kazibuthe.
