Neodymium hlau nplaum, raws li qhov siab - cov khoom siv hlau nplaum ruaj khov, muaj zog feem ntau vim lawv cov hlau nplaum muaj zog thiab cov khoom sib nqus ruaj khov.
Cov hlau nplaum no feem ntau yog tsim los ntawm cov khoom xws li neodymium, hlau, thiab boron, tsim los ntawm cov txheej txheem sintering tshwj xeeb. Qhov no ua rau muaj kev ua siab ntev thiab kev sib koom tes, ua rau lawv ntawm cov khoom siv hlau nplaum muaj zog tshaj plaws muaj hnub no. Lub zog ntawm cov hlau nplaum neodymium yog thawj zaug pom hauv lawv qhov kev xav tsis thoob cov hlau nplaum. Vim lawv cov remanence siab, txawm nyob rau hauv ib lub ntim me me, cov hlau nplaum neodymium tuaj yeem tsim cov hlau nplaum sib nqus kom deb tshaj li cov hlau nplaum ib txwm muaj, txaus nyiam cov khoom kaum lossis ntau pua zaus lawv qhov hnyav. Qhov muaj peev xwm txaus nyiam no ua rau cov hlau nplaum neodymium dav siv hauv kev sib nqus adsorption thiab sib nqus sib nqus. Qhov thib ob, lub zog ntawm cov hlau nplaum neodymium kuj tseem cuam tshuam rau hauv lawv cov khoom sib nqus ruaj khov. Piv rau lwm cov khoom sib nqus, cov hlau nplaum neodymium muaj cov khoom siv hluav taws xob ntau dua, txhais tau hais tias hauv tib lub ntim, cov hlau nplaum neodymium tuaj yeem khaws thiab tso tawm ntau lub zog sib nqus. Cov yam ntxwv no ua rau cov hlau nplaum neodymium zoo heev hauv cov ntawv thov uas xav tau siab -kev tswj cov hlau nplaum, xws li cov motors thiab sensors. Piv txwv li, nyob rau hauv lub tsav motors ntawm hluav taws xob tsheb, daim ntawv thov ntawm neodymium hlau nplaum yuav ho txhim kho lub cev muaj zog efficiency thiab lub zog tso zis.
Tsis tas li ntawd, cov hlau nplaum neodymium muaj qhov ntsuas kub zoo heev. Txawm hais tias lawv qhov ntsuas kub siab tshaj qhov kev txwv qis dua li lwm qhov siab tshaj - cov hlau nplaum ua haujlwm, cov hlau nplaum neodymium muaj cov khoom sib nqus ruaj khov nyob rau hauv ib txwm ua haujlwm thiab tsis yooj yim cuam tshuam los ntawm kev hloov pauv kub. Qhov no ua rau cov hlau nplaum neodymium siv dav hauv cov cuab yeej siv thiab cov khoom siv hluav taws xob siv hluav taws xob uas yuav tsum tau ua haujlwm ntev - lub sijhawm ruaj khov. Raws li cov qauv kev lag luam, kev tsim khoom thiab kev siv cov hlau nplaum neodymium ua raws li cov qauv kev tswj hwm nruj.
Los ntawm kev xaiv cov khoom siv raw mus rau kev tswj cov txheej txheem sintering, thiab tom qab ntawd mus rau kev sim thiab ntim cov khoom kawg, txhua kauj ruam yog ua tib zoo tsim thiab nruj tswj xyuas kom ntseeg tau tias qhov kev ua tau zoo thiab zoo ntawm cov hlau nplaum neodymium ncav cuag lawv qhov kev pom zoo. Txawm li cas los xij, thaum cov hlau nplaum neodymium muaj zog, qee qhov kev ceev faj yuav tsum tau ua thaum lawv siv. Piv txwv li, neodymium hlau nplaum yog rhiab heev rau cov hlau nplaum muaj zog thiab yuav tsum tau ceev kom deb ntawm cov khoom siv hlau nplaum muaj zog; Tsis tas li, cov hlau nplaum neodymium yog cov nkig thiab yuav tsum tau tiv thaiv los ntawm kev cuam tshuam hnyav thaum siv los tiv thaiv kev tawg.
