I-Neodymium Magnet, obeye aziwe njengoNdFeb Neodymium uzibuthe, i-tetragonal crystal system eyakhiwe yi-neodymium, insimbi ne-boron.Lo uzibuthe unamandla kazibuthe amaningi kunawoSmCo Permanent Magnets, uzibuthe omkhulu kunawo wonke emhlabeni ngaleso sikhathi.Kamuva, ukuthuthukiswa okuphumelelayo kwe-powder metallurgy, iGeneral Motors yathuthukisa ngempumelelo indlela yokuncibilikisa i-rotary jet, ingakhiqiza omazibuthe be-NdFeb.Lolu hlobo lukazibuthe manje lungolwesibili kuphela kuzibuthe onguziro we-holmium unomphela, luphinde lube yizibuthe zomhlaba ezingavamile ezivame ukusetshenziswa.Ozibuthe be-NdFeb basetshenziswa kakhulu emikhiqizweni ye-elekthronikhi efana nama-hard drive, omakhalekhukhwini, izindlebe namathuluzi asebenza ngebhethri.
I-NdFeb magnet, eyaziwa nangokuthi izinto ezingavamile zikazibuthe zomhlaba, iwuhlobo lweIzinto Zezibutheyenziwe futhi yafakwa i-sintered kusuka ku-praseodymium neodymium njengento eyinhloko eluhlaza.
Ukusetshenziswa kukazibuthe we-NdFeb kusipikha esikhuluma: ngenxa yokuthi ingxenye yayo eyinhloko i-neodymium kanye ne-alloying element yensimbi (fe-co), ngakho ibizwa ngokuthi i-NdFeb.Iwuhlobo lukazibuthe unomphela olusebenza kahle kakhulu, olusetshenziswa kabanzi embonini ye-elekthronikhi, ukukhiqizwa kwemishini kanye nezinsimbi.
I-NdFeb inezici ze-remanence ephezulu, ukuphoqelela okuphezulu namandla amakhulu kazibuthe.Ingakwazi ukugcina i-magnetism isikhathi eside ekushiseni okuphezulu ngaphandle kwe-oxygen.Ukuzinza okuhle kokushisa;Inokuqina okuhle kwamakhemikhali nokumelana nokugqwala okuphezulu.Isici sayo esikhulu ukuthi singagcwaliswa ngevolumu enkulu yamagnethi (kufika ngaphezu kwe-100kg), futhi insimu ye-demagnetic incane kakhulu (ayinakwa).Ngakho-ke, inethuba elibanzi lohlelo lokusebenza emkhakheni wensimu kazibuthe ephezulu.
Njengamanje, imikhiqizo yasekhaya ikakhulukazi ihlanganisa: hf50 ~ 70mm uchungechunge lokucaciswa, hf80 ~ 120mm uchungechunge lokucaciswa kanye nochungechunge lwe-smd izinhlobo ezintathu zemikhiqizo.Intengo yemikhiqizo ngokuvamile ingaphezu kuka-RMB 20,000 ngekhilogremu kuya ku-RMB 40,000.
Ngenxa yokuthi umkhiqizo usetshenziswa kakhulu futhi umthamo mkhulu, ukusetshenziswa kubalelwa kumakhulu ezinkulungwane zamathani minyaka yonke.Kodwa-ke, amazwe ambalwa kuphela emhlabeni angakhiqiza le Material entsha esebenzayo enokuqukethwe kobuchwepheshe obuphezulu kanye nenani eliphakeme elingeziwe, "High Quality Magnetic Material“.
