Puas yuav NdFeB hlau nplaum laus? Hais txog qhov teeb meem no, ntau tus neeg xav tias NdFeB hlau nplaum yog cov hlau nplaum ruaj khov. Cov khoom sib nqus ntawm hom hlau nplaum ruaj khov no tseem tsis hloov mus ib txhis nrog cov hlau nplaum nws tus kheej. Tab sis hauv kev xyaum, NdFeB cov khoom sib nqus yuav muaj hnub nyoog. Hauv kab lus hauv qab no, peb yuav kawm txog ob qho xwm txheej ntawm kev laus ntawm NdFeB cov khoom sib nqus thiab cov laj thawj uas cuam tshuam rau kev laus ntawm NdFeB cov khoom sib nqus.
1. NdFeB kev laus muab faib ua ob qhov xwm txheej:
1) Kub-kub demagnetization thiab aging, tshaj qhov siab tshaj plaws kev khiav hauj lwm kub ntawm NdFeB, cov hlau nplaum yuav raug txo los yog irreversible poob yuav tshwm sim.
2) Deg aging, tsis muaj kev kho deg los yog kev kho tsis zoo plating, yog nquag oxidation, corrosion, thiab accelerated aging.
2. Kev tshuaj xyuas ntawm cov laj thawj tseem ceeb ntawm NdFeB kev laus
1) Kub kub ib puag ncig
Muaj ntau qib ntawm NdFeB hlau nplaum, thiab txhua qib muaj qhov sib txawv siab tshaj plaws ua haujlwm kub thiab Curie kub. Thaum lub siab tshaj plaws kev khiav hauj lwm kub siab tshaj, lub magnetic zog ntawm NdFeB yuav irreversibly poob. Thaum Curie kub dhau lawm, cov hlau nplaum yuav ploj tag. Txoj kev daws teeb meem yog xaiv qhov sib piv NdFeB qib raws li qhov chaw ua haujlwm tiag tiag.
2) Qhov chaw ntub dej
NdFeB muaj cov khoom siv hlau, uas ua rau oxidation thiab corrosion. Nyob rau hauv qhov chaw ntub dej lossis ntsev tsuag, nws yuav ua rau muaj kev phom sij rau kev khaws cia ntawm NdFeB cov khoom sib nqus. Lub sij hawm ntev raug rau qhov chaw ntub dej no yuav ua rau cov txheej txheej ntawm NdFeB, uas yuav ua rau kom muaj kev laus ntawm NdFeB. Txoj kev daws teeb meem yog ua cov tshuaj tsuag ntsev thiab ua cov tshuaj ntsev tsuag txheej ntawm qhov sib txawv ntawm qhov ntev raws li ib puag ncig tiag tiag.
