Qhov nqus ntawm NdFeB cov hlau nplaum muaj zog npaum li cas?

Yuav ua li cas muaj zog yog qhov nqus ntawm NdFeB muaj zog hlau nplaum?

NdFeB Cov hlau nplaum tam sim no yog cov hlau nplaum ruaj khov tshaj plaws. NdFeB hlau nplaum yog tam sim no cov hlau nplaum uas muag muag tshaj plaws. Lawv hu ua vajntxwv ntawm magnetism. Lawv muaj cov khoom sib nqus siab heev thiab lawv qhov siab tshaj plaws Cov khoom siv hluav taws xob sib nqus (BHmax) yog ntau dua 10 npaug siab dua li ntawm ferrite. Nws kuj yog qhov feem ntau siv cov hlau nplaum tsawg hauv ntiaj teb tam sim no, thiab nws yog siv rau hauv ntau qhov chaw thiab cov cuab yeej xws li peb cov hlau nplaum ruaj khov motors, disk drives, thiab magnetic resonance imaging.

Nws tus kheej machinability kuj zoo heev. Qhov kub ua haujlwm tuaj yeem ncav cuag 200 degrees Celsius. Ntxiv mus, nws kev ntxhib los mos yog nyuaj, nws cov kev ua tau zoo yog ruaj khov, thiab nws muaj tus nqi zoo, yog li nws daim ntawv thov yog dav heev. Tab sis vim nws cov tshuaj lom neeg muaj zog, nws yuav tsum tau kho nrog ib qho chaw txheej. (Xws li Zn, Ni plating, electrophoresis, passivation, thiab lwm yam).

Lub ntsiab Cov khoom siv ntawm NdFeB hlau nplaum yog lub ntiaj teb tsis tshua muaj neodymium. Rare ntiaj teb tsis yog hu ua lub ntiaj teb tsis tshua muaj vim nws cov concentration tsawg, tab sis nws nyuaj dua rau cais dua li lwm cov ntaub ntawv txuas nrog cov khoom siv tshuaj lom neeg. Txawm tias cov Sib nqus attraction ntawm NdFeB hlau nplaum muaj zog heev, nws yog rumored tias NdFeB hlau nplaum tuaj yeem nqus tau 600 npaug ntawm lawv tus kheej qhov hnyav. Tab sis qhov tseeb, qhov no nqe lus tsis meej, vim hais tias cov magnetic attraction kuj cuam ​​tshuam los ntawm ntau yam mob xws li cov duab thiab nyob deb. Piv txwv li, rau hlau nplaum nrog tib txoj kab uas hla, qhov siab dua cov hlau nplaum, qhov muaj zog dua magnetic attraction quab yuam; rau cov hlau nplaum nrog tib qhov siab, qhov loj dua txoj kab uas hla, qhov ntau dua qhov sib nqus attraction quab yuam.
