NdFeB hlau nplaum yog cov khoom siv hlau nplaum nrov tshaj plaws nyob rau hauv kev ua lag luam, thaum xaiv NdFeB hlau nplaum, peb yuav tsum paub qhov txawv ntawm cov khoom ntawm NdFeB hlau nplaum nyob rau hauv kev ua lag luam, uas yog ntau conducive rau kev xaiv ntawm NdFeB hlau nplaum.
Cov khoom siv tseem ceeb ntawm NdFeB hlau nplaum yog dab tsi: Cov hlau nplaum hlau nplaum yog cov hlau nplaum: aluminium nickel cobalt hlau nplaum (ALNiCO), NdFeB hlau nplaum Nd2Fe14B), samarium cobalt hlau nplaum (SmCo).
1, NdFeB hlau nplaum (cov hlau nplaum muaj zog): Cov hlau nplaum no yog cov hlau nplaum ua haujlwm siab tshaj plaws hauv kev lag luam hlau nplaum ntawm lub khw tam sim no, tseem hu ua cov hlau nplaum muaj zog, nws muaj cov hlau nplaum muaj zog, nws cov khoom siv hlau nplaum siab tshaj plaws yog ntau dua 10 npaug siab dua. tshaj ferrite. Nws tus kheej mechanical processing kev ua tau zoo kuj zoo heev. Thaum qhov chaw ua haujlwm siab li 200 degrees, qhov kev ntxhib los mos tseem yog ib qho nyuaj thiab qhov kev ua tau zoo yog qhov ruaj khov, thiab tus nqi kuj zoo, yog li nws yog qhov dav hauv kev ua lag luam.
2, ferrite hlau nplaum: cov khoom tseem ceeb ntawm cov hlau nplaum no yog BaFe12O19 thiab SrFe12O19, cov txheej txheem ntau lawm yog ua los ntawm cov txheej txheem plooj (porcelain), kev ntxhib los mos ntawm cov hlau nplaum kuj nyuaj yog cov khoom siv tawv tawv, vim tias cov hlau nplaum ferrite muaj qhov kub thiab txias, tsis tshua muaj nqi, kev ua tau zoo nruab nrab, tau dhau los ua cov hlau nplaum ruaj khov tshaj plaws.
3, aluminium nickel cobalt hlau nplaum: Cov hlau nplaum no feem ntau yog tsim los ntawm txhuas, npib tsib xee, cobalt, hlau hlau thiab lwm yam kab hlau uas tsim los ntawm cov hlau nplaum, lub ntsiab feature yog tias cov yam ntxwv ntawm cov alloys tuaj yeem ua tiav ntau qhov sib txawv thiab cov duab ntawm cov hlau nplaum. , kev ua haujlwm tseem zoo heev. Nws yog tsuas yog siv nyob rau hauv ntau yam twj paj nruag thiab lwm yam kev siv.
