Kev hloov kub muaj qhov cuam tshuam tseem ceeb ntawm kev magnetism ntawm neodymium hlau nplaum. Cov khoom sib nqus ntawm NDFEt cov hlau nplaum hloov pauv ntawm cov kub kub sib txawv, raws li qhia hauv qab no:
Cov nyhuv ntawm qhov kub siab:
Raws li qhov ntsuas kub nce ntxiv, cov khoom sib nqus ntawm NDFEt cov hlau nplaum yog qhov tsis zoo. Thaum qhov ntsuas kub nce mus txog qhov ntsuas kub los ntawm NdFeb, cov hlau nplaum no ua rau qaug zog lossis txawm tias poob lawv cov hlauetism. Feem ntau hais lus, kev ua haujlwm siab tshaj plaws yog feem ntau 80 degree mus txog 230 degree, tshaj qhov kub tshaj plaws yuav ua rau muaj kev tsis muaj zog ntawm kev sib nqus teb lub zog. Piv txwv li, cov n series qib NDFEX cov khoom muaj qhov kev ua haujlwm kub tshaj plaws ntawm 80 ~ 180 degree, thiab qhov ntsuas ntawm kev ploj mus tas li ntawm cov magnetism yog 310 degree.
Cov nyhuv ntawm tsawg kub:
Ntawm qhov chaw kub qis dua, ndfeb hlau nplaum ua tau zoo dua, thiab lawv cov khoom sib nqus ua kom muaj zog thiab muaj zog npaum li qhov ntsuas kub. Qhov kev ua haujlwm tsawg kawg ntawm NDFEts yog hais txog {{0} ºC ({} ºF), thiab lawv tau ua qhov zoo tshaj plaws ntawm qhov kub no.
Kev sib tw thiab cov khoom sib sib zog nqus sib tw: raws li qhov kub nce ntxiv, cov hlau nplaum sib tw yuav maj mam txo qis, thaum lub sij hawm sib nqus kev nce ntxiv. Qhov no yog vim tias lub zog thermal yuav rhuav tshem kev npaj ua kom tiav ntawm cov sib nqus uas sib nqus, yog li txo cov khoom sib nqus.
Magnetation Magnetization:
Raws li qhov ntsuas kub nce ntxiv, qhov kev ruaj khov magnetization ntawm ndfeb hlau nplaum yuav poob. Qhov no yog vim hais tias, thaum muaj kev co siab kub, lub latsis kev co ntawm cov khoom nce, ua rau muaj kev txo qis hauv cov khoom sib nqus.
Kub coefficient: kev sib koom tes sib koom tes (HCI) ntawm NDFEt cov coefficient thaum nws hloov nrog qhov kub thiab txias, uas yog, kev tsav tsheb txo qis nrog kev nce qib.
Qhov kub muaj qhov cuam tshuam tseem ceeb rau cov khoom sib nqus ntawm cov khoom sib nqus ntawm ndfeb hlau nplaum. Nyob rau hauv qhov kev kub-ib puag ncig huab cua, cov khoom sib nqus yuav lwj lossis txawm qhov demagnetize; Thaum nyob rau hauv qis-kub ib puag ncig, cov khoom sib nqus yuav tau txhim kho. Yog li ntawd, thaum siv ndfeb hlau nplaum, nws yog ib qho tsim nyog los txiav txim siab lawv qhov kub thiab txias thiab tsis txhob siv lawv ntau dhau lossis qis dhau los tswj hwm lawv cov kev ua tau zoo.
