Txawm li cas los xij, cov hlau nplaum neodymium kuj yog nkig heev thiab tuaj yeem yooj yim tawg lossis tawg, yog li lawv yuav tsum tau ua tib zoo saib xyuas.
Zuag qhia tag nrho, cov hlau nplaum neodymium yog ib qho tseem ceeb hauv ntau cov thev naus laus zis niaj hnub vim lawv cov khoom sib nqus muaj zog thiab ntau yam.
3.Lub neej ntawm neodymium hlau nplaum yog dab tsi?
Neodymium hlau nplaum yog paub rau lawv cov magnetic teb muaj zog, tab sis lawv muaj ib tug tsawg lifespan. Lub neej ntawm cov hlau nplaum neodymium tuaj yeem sib txawv nyob ntawm ntau yam, suav nrog nws qhov loj me, cov duab, thiab ib puag ncig uas nws siv.
Feem ntau, cov hlau nplaum neodymium yog qhov ruaj khov thiab tuaj yeem siv tau ntau xyoo, txawm tias ntau xyoo, yog tias lawv siv thiab khaws cia kom zoo. Txawm li cas los xij, lawv tuaj yeem poob lawv lub zog sib nqus thaum lub sijhawm, tshwj xeeb tshaj yog tias lawv raug kub hnyiab los yog muaj zog sib nqus.
Qhov tseeb lifespan ntawm neodymium hlau nplaum yuav nyuaj rau kwv yees, vim nws nyob ntawm ntau yam. Tab sis nrog kev saib xyuas thiab kev saib xyuas kom zoo, cov hlau nplaum neodymium tuaj yeem siv tau ntev heev, thiab feem ntau ntev dua li lwm hom hlau nplaum.
Txhawm rau ua kom lub neej ntev tshaj plaws ntawm cov hlau nplaum neodymium, nws yog ib qho tseem ceeb uas yuav tsum khaws nws kom zoo, kom nws deb ntawm lwm cov hlau nplaum uas tuaj yeem cuam tshuam rau nws qhov chaw sib nqus, thiab tsis txhob tso nws mus rau qhov kub thiab txias lossis muaj zog sib nqus. Tsis tas li ntawd, cov hlau nplaum neodymium yuav tsum tau ua tib zoo saib xyuas, vim tias lawv nkig thiab tuaj yeem tawg yooj yim los yog tawg yog tias poob los yog mishandled.

4.Dab tsi yog qee yam txias uas kuv tuaj yeem ua nrog cov hlau nplaum neodymium?
Neodymium hlau nplaum yog qhov muaj zog heev thiab muaj ntau yam, thiab muaj ntau yam txias uas koj tuaj yeem ua nrog lawv. Nov yog ob peb lub tswv yim:
Tsim cov khoom sib nqus levitation: Koj tuaj yeem siv cov hlau nplaum neodymium los tsim cov cuab yeej levitation yooj yim, qhov twg ib lub hlau nplaum raug tshem tawm hauv huab cua saum lwm cov hlau nplaum. Qhov no tuaj yeem yog qhov kev lom zem thiab ua tau zoo tshaj plaws los ua kom pom lub zog ntawm cov hlau nplaum neodymium.
Ua ib qho sib nqus stirrer: Neodymium hlau nplaum tuaj yeem siv los tsim cov hlau nplaum sib nqus rau kev sim kev tshawb fawb lossis kev tsim khoom hauv tsev. Los ntawm muab cov hlau nplaum tso rau hauv ib lub thawv ntawm cov kua thiab siv cov hlau nplaum thib ob hauv qab lub thawv, koj tuaj yeem tsim cov nyhuv nplawm yam tsis tas yuav ua rau lub cev do cov kua.
Tsim ibmagnetic lub cev muaj zog: Neodymium hlau nplaum tuaj yeem siv los tsim lub cev muaj zog yooj yim uas khiav ntawm lub zog sib nqus siv hluav taws xob. Qhov no tuaj yeem yog qhov kev lom zem thiab kev kawm rau cov menyuam yaus lossis ib tus neeg nyiam siv hluav taws xob.
Tsim cov hniav nyiaj hniav kub sib nqus: Neodymium hlau nplaum tuaj yeem muab tso rau hauv kev tsim cov hniav nyiaj hniav kub, xws li sib nqus bracelets, necklaces, lossis qhwv ntsej. Qhov no tuaj yeem muab cov khoom siv tshwj xeeb thiab stylish thaum tseem ua kom zoo dua ntawm cov hlau nplaum cov khoom kho mob.
Ua ib qho sib nqusnuv ntses ua si: Neodymium hlau nplaum tuaj yeem siv los tsim kev lom zem nuv ntses, qhov twg cov hlau nplaum txuas mus rau qhov kawg ntawm cov kab nuv ntses thiab siv los "catch" cov khoom hlau hauv lub thawv dej.
Ua ib lub tsev fuabtais sib nqus nrogNdFeB hlau nplaum pob: muaj ntau hom NdFeB hlau nplaum pob nyob rau hauv kev ua lag luam niaj hnub no. Cov NdFeB hlau nplaum no feem ntau muaj yeeb yuj thiab sib nqus, thiab qee qhov txawm coated nrog glow-in-the-dub xim. Txawm hais tias koj xav ua si nrog lawv tus kheej lossis siv lawv nrog koj tus menyuam los pab lawv txhim kho lawv txoj kev muaj tswv yim, lawv yog qhov kev xaiv zoo.
5.Vim li cas neodymium hlau nplaum thiaj li muaj zog?
Cov hlau nplaum neodymium muaj zog heev vim lawv qhov sib xyaw ua ke ntawm cov ntsiab lus thiab cov qauv siv lead ua.
Cov hlau nplaum neodymium yog ua los ntawm cov hlau nplaum ntawm neodymium, hlau, thiab boron, thiab cov khoom neodymium yog cov hlau tsis tshua muaj hauv ntiaj teb uas paub txog nws cov khoom muaj zog sib nqus. Ntxiv nrog rau neodymium, cov hlau muaj lwm yam tsis tshua muaj hauv ntiaj teb, xws li dysprosium, terbium, lossis praseodymium, uas pab txhim kho cov khoom sib nqus ntawm cov khoom.
Cov qauv siv lead ua ntawm neodymium hlau nplaum kuj yog ib qho tseem ceeb hauv lawv lub zog. Cov khoom siv lead ua tau ua raws li txoj hauv kev tshwj xeeb thaum lub sijhawm tsim khoom, uas yuav pab tsim kom muaj qhov sib nqus zoo sib xws thoob plaws cov khoom siv. Cov txheej txheem kev sib raug zoo no yog hu ua "sintering" txheej txheem, uas muaj cov cua sov thiab compressing cov hmoov neodymium alloy rau hauv cov khoom thaiv.
Qhov tshwm sim ntawm cov xwm txheej no yog cov hlau nplaum nrog lub zog sib nqus zoo kawg uas tuaj yeem nyiam lossis tawm tsam lwm cov hlau nplaum los ntawm qhov deb. Qhov no ua rau cov hlau nplaum neodymium zoo tagnrho rau ntau yam kev siv, los ntawm kev siv tshuab rau cov neeg siv khoom siv hluav taws xob. Txawm li cas los xij, lawv lub zog kuj txhais tau hais tias lawv yuav tsum tau saib xyuas, vim tias lawv tuaj yeem ua rau cov khoom siv hluav taws xob tau yooj yim puas tsuaj lossis rub ntiv tes yog tias tsis siv.
