Raws li qhov tsis tshua muaj - cov khoom siv hlau nplaum hauv ntiaj teb feem ntau muaj xws li neodymium, hlau, thiab boron, neodymium hlau nplaum tau tsim txoj haujlwm tseem ceeb hauv ntiaj teb siab -kev tsim khoom kawg thiab kev txiav-ntev thev naus laus zis teb txij li kev ua tiav ntau lawm, ua tsaug rau ntau yam kev ua tau zoo. Lawv cov txiaj ntsig tsis yog tsuas yog cuam tshuam rau hauv lawv cov kev ntsuas kev ua tau zoo sib nqus, tab sis kuj tseem muaj peev xwm muab cov kev daws teeb meem zoo, compact, thiab txhim khu kev qha rau ntau qhov kev lag luam, yog li tsav kev ua tau zoo leaps thiab txhim kho cov qauv hauv cov khoom siv thiab cov tshuab.
Qhov zoo tshaj plaws ntawm neodymium hlau nplaum nyob hauv lawv cov khoom siv hluav taws xob tsis tshua muaj zog. Cov khoom siv hluav taws xob yog ib qho tseem ceeb parameter characterizing lub zog cia muaj peev xwm ntawm cov hlau nplaum ruaj khov. Neodymium hlau nplaum nyob deb tshaj cov khoom siv hlau nplaum ib txwm muaj, xws li ferrites thiab AlNiCo, hauv qhov ntsuas no, ncav cuag ob peb zaug lossis ntau tshaj kaum zaus tom qab. Qhov no txhais tau hais tias nyob rau hauv tib lub magnetic teb yuav tsum tau, neodymium hlau nplaum tuaj yeem ua tiav qhov sib npaug lossis muaj zog sib nqus cov nyhuv nrog lub ntim me me thiab sib dua, muab kev txhawb nqa tseem ceeb rau cov khoom siv me me thiab lub teeb yuag. Qhov no ua rau lawv tshwj xeeb tshaj yog haum rau qhov chaw - txwv tsis pub thiab hnyav- qhov chaw rhiab heev, xws li cov khoom siv hluav taws xob, cov cuab yeej kho mob nqa tau, thiab cov khoom siv dav hlau.
Thib ob, cov hlau nplaum neodymium muaj kev coercivity zoo heev thiab kev ua haujlwm zoo. High coercivity endows lawv nrog robust cov yam ntxwv, ua rau lawv resistant rau demagnetization nyob rau hauv muaj zog rov qab magnetic teb los yog complex electromagnetic ib puag ncig, thaum siab remanence kom ib tug nruam thiab ruaj khov magnetic teb tso zis. Ob tus yam ntxwv no ua ke lav qhov kev ntseeg tau ntawm cov khoom siv nyob rau hauv ntev - lub sijhawm ua haujlwm thiab cov xwm txheej sib txawv, ua rau lawv ua tau zoo nyob rau hauv cov xwm txheej uas yuav tsum tau ua kom muaj zog thiab ruaj khov, xws li tsav lub cev muaj zog rau lub tsheb tshiab, cua turbines, thiab servo systems rau industrial robots.
Thib peb, neodymium hlau nplaum tuaj yeem txhim kho lub zog hloov pauv tau zoo. Hauv cov tshuab hluav taws xob thiab cov tshuab hluav taws xob, qhov chaw sib nqus muaj zog thiab ruaj khov tuaj yeem txhim kho electromagnetic coupling, txo cov hlau nplaum thiab kub poob, yog li txo qis kev siv hluav taws xob, txo qhov kub thiab txias, thiab txuas ntxiv lub neej ntawm cov khoom siv. Qhov kom zoo dua no tsis tsuas yog ua raws li lub ntiaj teb sib txawv ntawm kev txuag hluav taws xob thiab kev txo qis emissions tab sis kuj ua rau txoj kev txhim kho tag nrho kev ua tau zoo thiab txo cov nqi khiav lag luam.
Tsis tas li ntawd, cov hlau nplaum neodymium kuj muaj qhov zoo hauv kev ua thiab hloov tau. Los ntawm kev paub tab txiav, sib sau, thiab txheej txheem kho saum npoo, lawv tuaj yeem tsim ua ntau yam duab thiab qhov ntau thiab tsawg kom tau raws li qhov sib txawv ntawm cov qauv thiab kev ua haujlwm kev xav tau; corrosion-tiv taus thiab oxidation- cov kev kho mob resistant tso cai rau lawv hloov mus rau ib puag ncig hnyav xws li cov av noo thiab ntsev tsuag, nthuav lawv daim ntawv thov ciam teb.
Txawm hais tias kev tsim cov hlau nplaum neodymium cuam tshuam nrog kev txhim kho thiab kev siv cov peev txheej tsawg hauv ntiaj teb thiab muaj qee qhov kev txwv, nws tseem yog cov khoom siv tseem ceeb rau kev tsav tsheb hloov kho thev naus laus zis hauv kev lag luam xws li lub zog, tsheb thauj mus los, kev tsim khoom, kev kho mob, thiab cov khoom siv hluav taws xob vim nws qhov kev ua tau zoo tsis tau hloov pauv. Nws tus nqi tseem yuav ua kom pom nyob rau hauv cov txheej txheem ntawm ntsuab, qis -carbon, thiab kev hloov pauv ntse.
