Txheeb xyuas qhov sib txawv ntawm NdFeB Magnets Thiab Ferrite Magnets

Tshawb xyuas qhov sib txawv ntawm NdFeB hlau nplaum thiab ferrite hlau nplaum? Thaum nws los txog rau cov hlau nplaum, kuv ntseeg tias txhua tus paub txog lawv. Qhov kev faib tawm tshwj xeeb yuav tsis meej. Qhov twg ntawm lawv yog NdFeB thiab magnetite zoo dua? Feem ntau, NdFeB muaj cov cuab yeej zoo thiab muaj txiaj ntsig zoo, thaum ferrite Lub cev yog ferromagnetic hlau oxide. Yuav ua li cas ib tug layman paub qhov txawv nws?

Qhov sib txawv tseem ceeb ntawm NdFeB hlau nplaum thiab ferrite hlau nplaum yog raws li nram no:

1. Kev ua haujlwm ntawm cov hlau nplaum ferrite tsis zoo li NdFeB.

2. Hais txog tus nqi. Ferrite yog pheej yig dua li NdFeB hlau nplaum.

3. NdFeB hlau nplaum muaj qhov kub thiab txias tsis kam, thaum cov hlau nplaum NdFeB zoo tib yam feem ntau tsuas yog 80 degrees Celsius, thiab demagnetization yuav tshwm sim thaum qhov kub thiab txias ua haujlwm tshaj qhov kub no.

4. Lub stability ntawm ferrite yog zoo heev. Nws yog ib qho oxide thiab ruaj khov heev. NdFeB yog ib qho alloy, uas yooj yim rau oxidize thiab yuav tsum tau tiv thaiv los ntawm txheej.
