Cov hlau nplaum neodymium, tseem hu ua NdFeB lossis cov hlau nplaum tsis tshua muaj, tau dhau los ua lub hauv paus ntawm thev naus laus zis niaj hnub no. Lawv txoj kev taug kev los ntawm kev tsim kho tshiab mus rau kev siv dav dav yog ib qho pov thawj rau tib neeg lub tswv yim thiab kev nrhiav tsis tu ncua ntawm cov khoom siv zoo dua thiab muaj zog dua.

Kev Tsim Kho ntawm Neodymium Magnets

Cov hlau nplaum neodymium tau tsim thawj zaug thaum ntxov xyoo 1980s vim yog kev siv zog los tsim cov hlau nplaum ruaj khov uas muaj zog dua. Kev tsim kho no yog kev koom tes ntawm General Motors thiab Sumitomo Special Metals. Cov kws tshawb fawb tab tom nrhiav ib lub hlau nplaum uas tuaj yeem hloov cov hlau nplaum samarium-cobalt, uas muaj zog tab sis kim thiab nyuaj rau tsim.

Qhov kev tshawb pom tshiab no tau los nrog kev tshawb pom tias cov hlau nplaum neodymium, hlau, thiab boron (NdFeB) tuaj yeem tsim cov hlau nplaum uas muaj zog dua ntawm tus nqi qis dua. Cov hlau nplaum tshiab no tsis yog tsuas yog muaj zog dua li nws cov thawj coj xwb tab sis kuj muaj ntau dua vim muaj neodymium piv rau samarium. Cov hlau nplaum neodymium thawj zaug tau tsim tawm xyoo 1984, uas yog qhov pib ntawm lub sijhawm tshiab hauv kev sib nqus.

Kev Txhim Kho thiab Kev Txhim Kho

Tau ntau xyoo los lawm, muaj kev nce qib tseem ceeb hauv kev tsim khoom thiab kev kho kom zoo ntawm cov hlau nplaum neodymium. Cov qauv thaum ntxov tau yooj yim rau xeb thiab muaj qhov kub ua haujlwm qis dua. Txhawm rau daws cov teeb meem no, cov chaw tsim khoom tau tsim ntau yam txheej txheem, xws li nickel, zinc, thiab epoxy, los tiv thaiv cov hlau nplaum los ntawm kev puas tsuaj rau ib puag ncig. Tsis tas li ntawd, kev nce qib hauv cov txheej txheem tsim khoom tau tso cai rau kev tsim cov hlau nplaum nrog kev kam rau siab dua thiab kev ruaj khov ntawm cov hlau nplaum.

Kev tsim cov hlau nplaum neodymium sib txuas, uas cuam tshuam nrog kev muab cov khoom me me NdFeB tso rau hauv cov polymer matrix, tau nthuav dav ntxiv rau ntau yam kev siv. Cov hlau nplaum sib txuas no tsis yooj yim tawg thiab tuaj yeem pwm rau hauv cov duab nyuaj, muab kev ywj pheej ntau dua rau cov engineers.

Cov Ntawv Thov Niaj Hnub

Niaj hnub no, cov hlau nplaum neodymium muaj nyob rau hauv ntau yam kev siv vim lawv lub zog zoo dua thiab kev hloov pauv tau yooj yim. Qee qhov kev siv feem ntau suav nrog:

Khoom Siv Hluav Taws Xob:Cov hlau nplaum neodymium yog cov khoom tseem ceeb hauv ntau yam khoom siv hluav taws xob niaj hnub no, suav nrog cov xov tooj ntse, khoos phis tawj, thiab lub mloog pob ntseg. Lawv qhov me me thiab lub zog sib nqus siab ua rau lawv zoo tagnrho rau kev siv hauv cov khoom siv me me, ua haujlwm tau zoo.

Cov Tsav Tsheb Hluav Taws Xob:Qhov ua tau zoo thiab lub zog ntawm cov tshuab hluav taws xob hauv txhua yam los ntawm cov khoom siv hauv tsev mus rau cov tsheb hluav taws xob vam khom ntau rau cov hlau nplaum neodymium. Lawv lub peev xwm los tsim cov teb sib nqus muaj zog hauv qhov chaw me me tau hloov pauv txoj kev tsim tshuab, ua rau cov tshuab me me thiab ua haujlwm tau zoo dua.

Cov Khoom Siv Kho Mob:Hauv kev kho mob, cov hlau nplaum neodymium siv rau hauv cov tshuab MRI, cov tshuab pacemakers, thiab cov khoom siv kho mob magnetic. Lawv cov teb magnetic muaj zog yog qhov tseem ceeb rau qhov tseeb thiab kev ntseeg tau uas xav tau hauv kev siv tshuab kho mob.

Lub Zog Rov Ua Dua Tshiab:Cov hlau nplaum neodymium ua lub luag haujlwm tseem ceeb hauv kev tsim hluav taws xob huv. Lawv siv rau hauv cov cua turbines thiab lwm yam thev naus laus zis hluav taws xob rov ua dua tshiab, qhov twg lawv cov kev ua haujlwm zoo thiab lub zog pab txhawb rau kev tsim hluav taws xob ruaj khov.

Cov Ntawv Thov Kev Lag Luam:Tsis tas li ntawm cov khoom siv hluav taws xob thiab cov khoom siv kho mob, cov hlau nplaum neodymium kuj siv tau rau ntau yam kev siv hauv kev lag luam, suav nrog cov khoom sib cais sib nqus, cov tshuab nqa khoom, thiab cov sensors. Lawv lub peev xwm los tswj cov khoom sib nqus hauv qab qhov xwm txheej hnyav ua rau lawv tsis tseem ceeb hauv ntau cov txheej txheem kev lag luam.

Yav Tom Ntej ntawm Neodymium Magnets

Raws li qhov kev thov rau cov khoom siv me me, ua haujlwm tau zoo dua txuas ntxiv mus, qhov kev xav tau rau cov hlau nplaum muaj zog zoo li cov uas ua los ntawm neodymium kuj yuav loj hlob tuaj. Cov kws tshawb fawb tam sim no tab tom tshawb nrhiav txoj hauv kev los txo qhov kev vam khom rau cov khoom siv tsis tshua muaj los ntawm kev tsim cov hlau nplaum tshiab thiab cov txheej txheem tsim khoom. Tsis tas li ntawd, kev siv rov qab thiab kev nrhiav tau cov neodymium ruaj khov tau dhau los ua qhov tseem ceeb thaum qhov kev thov thoob ntiaj teb nce siab.

Kev hloov pauv ntawm cov hlau nplaum neodymium tseem tsis tau xaus. Nrog kev tshawb fawb thiab kev txhim kho tas mus li, cov hlau nplaum no tau npaj siab los ua lub luag haujlwm tseem ceeb hauv cov thev naus laus zis ntawm yav tom ntej, tsav tsheb tsim kho tshiab thoob plaws hauv kev lag luam thiab pab txhawb rau kev nce qib hauv txhua yam los ntawm cov khoom siv hluav taws xob rau cov neeg siv khoom mus rau lub zog rov ua dua tshiab.
