Kuj tseem hu ua cov hlau nplaum neo, cov hlau nplaum neodymium yog ib hom hlau nplaum uas tsis tshua muaj hauv ntiaj teb uas muaj xws li neodymium, hlau thiab boron. Txawm hais tias muaj lwm cov hlau nplaum uas tsis tshua muaj hauv ntiaj teb - suav nrog samarium cobalt - neodymium yog nyob deb ntawm ntau tshaj. Lawv tsim muaj zog magnetic teb, tso cai rau ib tug superior theem ntawm kev ua tau zoo. Txawm hais tias koj tau hnov txog cov hlau nplaum neodymium, txawm li cas los xij, tej zaum muaj qee yam uas koj tsis paub txog cov hlau nplaum nrov hauv ntiaj teb no.
✧ Txheej txheem cej luam ntawm Neodymium Magnets
Dubbed lub ntiaj teb lub zog ruaj khov hlau nplaum, neodymium hlau nplaum yog cov hlau nplaum ua los ntawm neodymium. Txhawm rau muab lawv lub zog rau hauv kev xav, lawv tuaj yeem tsim cov hlau nplaum nrog txog 1.4 teslas. Neodymium, tau kawg, yog lub ntiaj teb tsis tshua muaj lub ntiaj teb uas muaj tus lej atomic 60. Nws tau pom nyob rau xyoo 1885 los ntawm kws tshuaj Carl Auer von Welsbach. Nrog rau qhov hais tias, nws tsis yog txog ze li ib puas xyoo tom qab kom txog thaum cov hlau nplaum neodymium tau tsim.
Lub zog tsis sib xws ntawm cov hlau nplaum neodymium ua rau lawv xaiv zoo rau ntau yam kev lag luam, qee qhov muaj xws li hauv qab no:
ㆍHard disk drives (HDDs) rau computers
ㆍ Qhov rooj xauv
ㆍElectric automotive engines
ㆍ Electric generators
ㆍVoice coils
ㆍ Cov cuab yeej siv hluav taws xob tsis muaj zog
ㆍLub kauj tsheb fais fab
ㆍ Hais lus thiab lub mloog pob ntseg
Cov khoom lag luam decouplers

✧ Keeb kwm ntawm Neodymium Magnets
Neodymium hlau nplaum tau tsim nyob rau hauv thaum ntxov 1980s los ntawm General Motors thiab Sumitomo Special Metals. Cov tuam txhab nrhiav pom tias los ntawm kev sib txuas neodymium nrog me me ntawm cov hlau thiab boron, lawv muaj peev xwm tsim tau cov hlau nplaum muaj zog. General Motors thiab Sumitomo Cov Hlau Tshwj Xeeb tom qab ntawd tso tawm lub ntiaj teb thawj cov hlau nplaum neodymium, muab cov txiaj ntsig zoo rau lwm cov hlau nplaum uas tsis tshua muaj hauv ntiaj teb hauv kev ua lag luam.
✧ Neodymium VS Ceramic Magnets
Yuav ua li cas neodymium hlau nplaum piv rau cov hlau nplaum ceramic raws nraim? Ceramic hlau nplaum yog undoubtedly pheej yig dua, ua rau lawv ib tug nrov kev xaiv rau cov neeg siv khoom. Rau cov ntawv thov kev lag luam, txawm li cas los xij, tsis muaj kev hloov pauv rau cov hlau nplaum neodymium. Raws li tau hais dhau los, cov hlau nplaum neodymium tuaj yeem tsim cov hlau nplaum nrog txog 1.4 teslas. Hauv kev sib piv, cov hlau nplaum ceramic feem ntau tsim cov hlau nplaum nrog tsuas yog 0.5 mus rau 1 teslas.
Tsis yog tsuas yog cov hlau nplaum neodymium muaj zog dua li cov hlau nplaum ceramic xwb; lawv kuj nyuaj dua thiab. Cov hlau nplaum ceramic yooj yim tawg, ua rau lawv yooj yim puas tsuaj. Yog tias koj poob cov hlau nplaum ceramic rau hauv av, muaj feem ntau nws yuav tawg. Cov hlau nplaum neodymium, ntawm qhov tod tes, yog cov khoom siv tawv dua, yog li lawv yuav tsis tawg thaum poob lossis raug kev ntxhov siab.
Ntawm qhov tod tes, cov hlau nplaum ceramic muaj qhov tiv taus corrosion ntau dua li cov hlau nplaum neodymium. Txawm tias thaum raug cov av tsis tu ncua, cov hlau nplaum ceramic feem ntau yuav tsis xeb lossis xeb.
✧ Tus Neeg Muag Khoom Neodymium Magnet
AH Magnet yog lub tuam txhab muag khoom siv hlau nplaum tsis tshua muaj neeg tshwj xeeb hauv kev tshawb fawb, kev txhim kho, kev tsim khoom thiab kev xa tawm cov hlau nplaum sintered neodymium hlau boron uas muaj kev ua tau zoo, muaj 47 qib ntawm cov hlau nplaum neodymium txheem, txij li N33 txog 35AH, thiab GBD Series txij li 48SH txog 45AH.
