Yuav ua li cas neodymium hlau boron tsim?

Neodymium hlau boron yog cov khoom siv hlau nplaum tshiab uas muaj cov khoom zoo heev xws li cov hlau nplaum muaj zog, cov khoom siv hluav taws xob zoo sib nqus, thiab cov tshuaj lom neeg zoo. Nws yog dav siv nyob rau hauv teb xws li hluav taws xob motors, tsheb, aerospace, thiab yog lub npe hu ua magnetic huab tais ntawm lub xyoo pua 21st.
Neodymium hlau boron (NdFeB) yog ib yam tshiab ntawm cov khoom siv hlau nplaum ruaj khov, uas yog ib qho tseem ceeb ntawm cov khoom siv hluav taws xob niaj hnub, kev sib txuas lus, tsheb, lub cev muaj zog thiab lwm yam kev lag luam vim nws qhov kev ua haujlwm ruaj khov thiab cov khoom siv hluav taws xob sib nqus. Yog li, nws tau ua li cas?
Ua ntej, cov khoom siv raw rau kev tsim neodymium hlau boron yog cov khoom xws li neodymium, hlau, thiab boron. Cov ntaub ntawv nyoos no tau muab sib xyaw rau hauv ib qho kev faib ua feem thiab ua rau cov alloys, uas yog rhuab thiab txias rau hauv lub tshuab nqus tsev vacuum kom tau txais neodymium hlau boron billets.
Tom ntej no, txiav cov neodymium hlau boron dawb paug rau hauv cov duab thiab qhov loj me, thiab tom qab ntawd muab kev sib tsoo, polishing, thiab lwm yam txheej txheem los ua kom nws qhov chaw du thiab qhov loj. Nyob rau tib lub sijhawm, kev sib xyaw ua ke lossis cov txheej txheem kev daws teeb meem yog siv los ua cov txheej txheem ntawm neodymium hlau boron los txhim kho nws cov oxidation tsis kam thiab hnav kev ua haujlwm.
Thaum kawg, neodymium hlau boron yog magnetized kom muaj ib qho kev taw qhia ntawm hlau nplaum. Cov txheej txheem no feem ntau yuav tsum tau ua kom tiav nyob rau hauv ib tug muaj zog magnetic teb, feem ntau yog siv batch automatic magnetization khoom los yog phau ntawv ua hauj lwm los magnetize ib tug loj tus naj npawb ntawm cov qauv.
Nws tuaj yeem pom tau tias kev tsim cov neodymium hlau boron yuav tsum muaj cov txheej txheem nruj thiab siv tshuab, nrog rau cov cuab yeej siv siab thiab cov neeg ua haujlwm. Tab sis nyob rau hauv lub sij hawm ntev, kev tsim neodymium hlau boron tau ua lub luag haujlwm zoo hauv kev txhawb nqa kev lag luam kev txhim kho thiab kev ua haujlwm thev naus laus zis, thiab kuj tau coj cov txiaj ntsig zoo dua thiab yooj yim rau tib neeg kev tsim khoom thiab lub neej.
