Kev saib xyuas yuav tsum tau ua thaum tuav NdFeB hlau nplaum ntawm qhov kub thiab txias, vim hais tias NdFeB hlau nplaum yog nquag demagnetization ntawm qhov kub thiab txias. Hauv qab no peb yuav ua haujlwm nrog koj kom paub txog qhov teeb meem ntawm qhov kub thiab txias demagnetization ntawm NdFeB hlau nplaum. Txij li thaum NdFeB hlau nplaum muaj cov hlau nplaum NdFeB siab, lawv kuj muaj oxidation, yog li cov txheej txheem ntau yam uas ua tau raws li cov xwm txheej no nyob ntawm qhov chaw ua haujlwm ntawm NdFeB hlau nplaum.
Yog vim li cas vim li cas NdFeB demagnetizes nyob rau hauv qhov kub thiab txias ib puag ncig yog txiav txim los ntawm nws lub cev qauv. Feem ntau, vim li cas cov hlau nplaum tuaj yeem tsim cov hlau nplaum yog vim cov electrons nqa los ntawm cov khoom nws tus kheej tig ib ncig ntawm cov atoms raws li cov kev taw qhia, yog li tsim cov hlau nplaum sib nqus, uas ua rau muaj kev cuam tshuam rau ib puag ncig.
Txawm li cas los xij, kev sib hloov ntawm electrons nyob ib ncig ntawm atoms nyob rau hauv ib tug predetermined kev taw qhia kuj raug rau kub tej yam kev mob. Cov khoom sib nqus sib txawv tuaj yeem tiv taus qhov kub thiab txias. Thaum qhov kub thiab txias heev, cov electrons yuav deviate los ntawm qhov qub orbit, ua rau chaos. Lub sijhawm no, cov hlau nplaum Lub zos magnetic teb ntawm cov khoom yuav cuam tshuam, uas ua rau demagnetization.
Qhov kub tsis kam ntawm cov hlau nplaum muaj zog NdFeB yog li 200 degrees, yog tias nws tshaj 200 degrees, demagnetization yuav tshwm sim. Yog tias qhov kub siab dua, qhov demagnetization yuav hnyav dua.
Ntau cov kev daws teeb meem zoo rau kev kub siab demagnetization ntawm NdFeB hlau nplaum:
Tsis txhob nthuav tawm cov khoom siv hlau nplaum NdFeB rau qhov kub thiab txias heev. Ua tib zoo saib xyuas nws qhov ntsuas kub tseem ceeb, uas yog 200 degrees, thiab kho nws qhov chaw ua haujlwm kub hauv lub sijhawm kom txo qis qhov tshwm sim ntawm demagnetization.
Peb yuav tsum pib nrog kev siv tshuab los txhim kho kev ua tau zoo ntawm cov khoom siv hlau boron hlau nplaum kom lawv tuaj yeem muaj cov qauv sov dua thiab tsis tshua muaj kev cuam tshuam rau ib puag ncig.
