Cov hlau nplaum tau siv dav hauv kev lag luam niaj hnub no. Nyob rau hauv cov txheej txheem ntau lawm, peb feem ntau yuav tsum tau siv qhov kub thiab txias ib puag ncig, thiab kub resistant hlau nplaum yog qhov tseem ceeb tshwj xeeb. Txawm li cas los xij, yuav ua li cas txheeb xyuas seb tus qauv hlau nplaum tuaj yeem tiv taus qhov kub siab? Cia peb saib hauv qab no.
Ua ntej tshaj plaws, txhawm rau txheeb xyuas seb tus qauv hlau nplaum puas tiv taus qhov kub siab, peb yuav tsum nkag siab txog cov khoom ntawm cov hlau nplaum nws tus kheej. Nyob rau hauv qhov kub thiab txias ib puag ncig, coercivity ntawm ib co khoom siv hlau nplaum, xws li nyuaj ferrite thiab Nd-Fe-B, yuav poob qis, ua rau lawv poob magnetism. Cov khoom siv hlau nplaum nrog kev sib zog siab dua, xws li NdFeB thiab ferrite, tseem muaj cov hlau nplaum muaj zog ntawm qhov kub thiab txias, uas yuav tsum tau peb xaiv cov khoom siv nrog kev sib zog siab thaum xaiv cov khoom siv hlau nplaum.
Qhov thib ob, peb tuaj yeem ua qee qhov kev sim los txiav txim siab seb cov hlau nplaum tiv taus qhov kub thiab txias. Piv txwv li, peb tuaj yeem muab cov qauv hlau nplaum tso rau hauv lub qhov cub kub kom sov kom pom seb qhov kev ua haujlwm ntawm cov hlau nplaum yuav hloov pauv li cas. Tsis tas li ntawd, peb tseem tuaj yeem ntub cov qauv hlau nplaum hauv cov dej kub kom pom seb qhov kev ua haujlwm ntawm cov hlau nplaum yuav hloov pauv li cas. Yog tias cov hlau nplaum tuaj yeem tswj tau qee qhov sib nqus quab yuam nyob rau hauv qhov kub thiab txias ib puag ncig, ces nws tuaj yeem txiav txim siab ua kom tiv taus kub.
Ntxiv dua thiab, peb tuaj yeem txiav txim siab seb cov hlau nplaum tiv taus qhov kub thiab txias los ntawm nws cov tsos. Nyob rau hauv ib puag ncig kub, qee cov khoom siv hlau nplaum, xws li tawv ferrite thiab Nd-Fe-B, yuav raug thermal expansion, uas ua rau tawg thiab deformation ntawm cov qauv hlau nplaum. High-temperature resistant hlau nplaum yuav tsis tsuas muaj zog hlau nplaum, tab sis kuj muaj kev ruaj ntseg thiab yuav tsis undergo thermal expansion.
Txhawm rau kom ntseeg tau qhov ntsuas kub ntawm cov hlau nplaum, peb yuav tsum xaiv cov khoom siv hlau nplaum nrog kev ua haujlwm siab thiab ua cov kev sim los ntsuas lawv qhov kev ruaj ntseg hauv qhov kub thiab txias. Nyob rau tib lub sijhawm, peb kuj yuav tsum txiav txim siab seb cov qauv hlau nplaum tiv taus qhov kub thiab txias los ntawm nws cov tsos.
