NdFeB cov khoom siv hlau nplaum ruaj khov yog cov hlau nplaum ntawm neodymium thiab hlau oxide. Raws li qhov tseeb tshwm sim ntawm kev tsim cov khoom siv hlau nplaum tsis tshua muaj hauv ntiaj teb, nws tau siv dav vim nws cov khoom sib nqus zoo heev thiab yog lub npe hu ua "tus huab tais hlau nplaum" ntawm kev lag luam hlau nplaum. NdFeB muaj cov khoom siv hluav taws xob sib nqus siab heev thiab lub zog quab yuam, thiab tib lub sijhawm, qhov zoo ntawm lub zog siab ceev ua rauNdFeB hlau nplaumcov khoom siv dav siv hauv kev lag luam niaj hnub thiab tshuab hluav taws xob. Ntau tus neeg muas zaub xaiv yuav cov hlau nplaum vim lawv xaiv NdFeB hlau nplaum. Muaj ntau qib ntawm cov hlau boron cov khoom siv hlau nplaum ruaj khov, thiab tej zaum yuav muaj kev txhawj xeeb. Kuv yuav xaiv li cas qib sib raug ntawm NdFeB cov khoom siv hlau nplaum ruaj khov? Cov khoom lag luam NdFeB kuv yuav tsum tau kho yog dab tsi yog qhov tshwj xeeb ntawm lub zog sib nqus, cov khoom siv hluav taws xob sib nqus siab tshaj plaws, kev ua haujlwm kub, lub zog quab yuam, thiab lwm yam?
1. Los ntawm kev xaav ntawm magnetism:
Lub zog sib nqus zoo heev ntawm NdFeB yog nws cov yam ntxwv loj tshaj plaws, uas yog vim li cas nws thiaj li tuaj yeem nce tau sai sai hauv kev ua lag luam. Xaiv lub NdFeB hlau nplaum ua ntej nyob ntawm seb hom hlau nplaum koj xav tau, thiab hom kev nqus nqus qhov loj npaum li cas ntawm cov hlau nplaum xav tau. Tau kawg, Cov duab ntawm cov hlau nplaum tuaj yeem kho raws li qhov xav tau ntawm cov neeg siv khoom. Ntawm qhov kev txiav txim siab qhov loj me, peb yuav xaiv cov khoom siv qib sib xws. Los ntawm N35 mus rau N52 qib, tus lej loj dua, lub zog sib nqus zog dua.
2. Los ntawm qhov kev xav ntawm kev ua haujlwm kub:
Cov kev xaiv kub sib txawv sib haum rau cov qib sib txawv. Xaiv N iav hauv 80 degrees, M iav hauv 100 degrees, H iav hauv 120 degrees, SH iav hauv 150 degrees, UH iav hauv 180 degrees, thiab EH iav hauv 200 degrees.
