Cov phooj ywg uas paub txog cov hlau nplaum yog paub tias cov hlau nplaum hlau boron tam sim no tau lees paub hauv cov khoom siv hlau nplaum ua lag luam raws li cov khoom siv hlau nplaum uas muaj txiaj ntsig zoo thiab raug nqi zoo. Lawv yog npaj rau siv nyob rau hauv ntau yamhigh-tech kev lag luams, suav nrog kev tiv thaiv hauv tebchaws thiab tub rog, tshuab hluav taws xob, thiab khoom siv kho mob, lub cev muaj zog, khoom siv hluav taws xob, khoom siv hluav taws xob, thiab lwm yam. Qhov ntau lawv siv, nws yooj yim dua los txheeb xyuas cov teeb meem. Ntawm cov no, demagnetization ntawm hlau-boron muaj zog hlau nplaum nyob rau hauv qhov kub thiab txias tau txais ntau qhov kev txaus siab.Ua ntej thiab foremost, peb yuav tsum to taub yog vim li cas NeFeB demagnetizes nyob rau hauv high kub ib puag ncig.
Lub cev qauv ntawm Ne hlau boron txiav txim siab vim li cas nws demagnetizes nyob rau hauv qhov kub thiab txias. Feem ntau, cov hlau nplaum tuaj yeem tsim cov hlau nplaum vim tias cov khoom siv hluav taws xob thauj los ntawm cov khoom nws tus kheej tig ib ncig ntawm cov atoms hauv ib qho kev taw qhia tshwj xeeb, uas ua rau lub zog sib nqus uas muaj kev cuam tshuam tam sim ntawm ib puag ncig kev sib txuas. Txawm li cas los xij, cov xwm txheej tshwj xeeb yuav tsum tau ua kom tau raws li cov khoom siv hluav taws xob kom tig mus ncig atoms hauv ib qho kev taw qhia tshwj xeeb. Kub kam rau siab sib txawv ntawm cov khoom sib nqus. Thaum qhov kub nce siab dhau lawm, cov hluav taws xob tawm ntawm lawv qhov qub orbit, uas ua rau muaj kev kub ntxhov. Qhov no Lub sijhawm no, cov khoom sib nqus hauv zos magnetic teb yuav cuam tshuam, ua raudemagnetization.Lub demagnetization kub ntawm cov hlau hlau boron feem ntau yog txiav txim los ntawm nws cov kev muaj pes tsawg leeg, magnetic teb lub zog, thiab kev kho cua sov keeb kwm. Lub demagnetization kub ntau rau kub hlau boron yog feem ntau ntawm 150 thiab 300 degrees Celsius (302 thiab 572 degrees Fahrenheit). Nyob rau hauv qhov kub thiab txias, cov yam ntxwv ferromagnetic maj mam deteriorate kom txog thaum lawv poob tag.
Ntau qhov kev daws teeb meem zoo rau NeFeB hlau nplaum siab kub demagnetization:
Ua ntej thiab qhov tseem ceeb, tsis txhob overheat NeFeB hlau nplaum khoom. Khaws qhov muag ze ntawm nws qhov kub thiab txias. Ib qho piv txwv NeFeB hlau nplaum qhov kub tseem ceeb yog feem ntau nyob ib ncig ntawm 80 degrees Celsius (176 degrees Fahrenheit). Kho nws qhov chaw ua haujlwm sai li sai tau. Demagnetization tuaj yeem txo los ntawm kev nce qhov kub.
Qhov thib ob, nws yog los pib nrog kev siv tshuab los txhim kho kev ua haujlwm ntawm cov khoom siv cov hlau nplaum plaub hau kom lawv tuaj yeem muaj cov qauv sov dua thiab tsis tshua muaj kev cuam tshuam rau ib puag ncig.
Thib peb, nrog tib yam khoom siv hluav taws xob sib nqus, koj tuaj yeem xaivhigh coercivity ntaub ntawv. Yog tias ua tsis tau, koj tsuas tuaj yeem tso me me ntawm cov khoom siv hluav taws xob sib nqus kom ua tiav qhov kev coercivity siab dua.
PS: Txhua yam khoom muaj cov yam ntxwv sib txawv, yog li xaiv qhov tsim nyog thiab pheej yig, thiab ua tib zoo xav thaum tsim, txwv tsis pub nws yuav ua rau poob!
Xav tias koj tseem xav tau: Yuav ua li cas txo lossis tiv thaiv thermal demagnetization thiab oxidation ntawm hlau boron, uas ua rau txo qis coercivity?
Teb: Qhov no yog qhov teeb meem nrog thermal demagnetization. Nws yog qhov nyuaj los tswj. Ua tib zoo saib xyuas qhov ntsuas kub, lub sijhawm thiab lub tshuab nqus tsev kawm ntawv thaum lub sijhawm demagnetization.
Dab tsi zaus yuav cov hlau nplaum hlau-boron vibrate thiab ua demagnetized?
Cov hlau nplaum ntawm cov hlau nplaum tas mus li yuav tsis raug demagnetized vim qhov kev co zaus, thiab lub zog ceev ceev yuav tsis demagnetized txawm tias qhov ceev mus txog 60,000 rpm.
Cov ntsiab lus hlau nplaum saum toj no tau muab tso ua ke thiab sib koom los ntawm Hangzhou Magnet Power Technology Co., Ltd. Yog tias koj muaj lwm yam lus nug hlau nplaum, thov koj xav tiv tauj pebtham nrog kev pabcuam hauv online!
