Neodymium hlau nplaum, kuj hu uaNdFeB hlau nplaum, yog covmuaj zog ruaj khov hlau nplaummuaj. Uas feem ntau ntawm neodymium, hlau, thiab boron, cov hlau nplaum no tau hloov pauv ntau yam kev lag luam vim lawv qhov zoo tshaj plaws sib nqus zog thiab ntau yam. Txawm li cas los xij, ib lo lus nug tshwm sim: Puas yog cov hlau nplaum neodymium tsim cov nplaim taws? Txhawm rau teb cov lus nug no, peb yuav tsum delve tob rau hauv cov khoom ntawm cov nohlau nplaums thiab tej yam kev mob nyob rau hauv uas sparks yuav tshwm sim.
Cov khoom ntawm Neodymium Magnets
Neodymium hlau nplaum yog cov hlau nplaum uas tsis tshua muaj ntiaj teb paub txog lawv cov khoom sib nqus zoo dua. Lawv muaj zog ntau dua li cov hlau nplaum, xws li cov hlau nplaum lossis cov hlau nplaum alnico, ua rau lawv zoo tagnrho rau cov ntawv thov xws li hluav taws xob motors mus rau magnetic resonance imaging (MRI) cov cav tov. NdFeB hlau nplaum tshuav lawv lub zog rau lawv cov qauv siv lead ua tshwj xeeb, uas tso cai rau lub zog sib nqus sib nqus.
Cov hlau nplaum neodymium puas tsim cov nplaim taws?
Nyob rau hauv luv luv, neodymium hlau nplaum lawv tus kheej yuav tsis tsim sparks. Txawm li cas los xij, sparks yuav tshwm sim nyob rau hauv qee qhov xwm txheej, tshwj xeeb tshaj yog thaum cov hlau nplaum no siv nrog cov khoom siv hluav taws xob lossis hauv qee yam kev siv tshuab.
1. Mechanical Impact: Thaum ob lub neodymium hlau nplaum sib tsoo nrog lub zog loj, lawv tuaj yeem tsim cov nplaim taws vim qhov nrawm nrawm thiab kev sib txhuam ntawm qhov chaw. Qhov no yuav tshwm sim ntau dua yog tias cov hlau nplaum loj thiab hnyav, vim tias lub zog kinetic koom nrog qhov cuam tshuam tuaj yeem loj. Cov sparks tsis yog los ntawm cov hlau nplaum cov khoom sib nqus, tab sis yog lub cev sib cuam tshuam ntawm cov hlau nplaum.
2. Kev siv hluav taws xob: Hauv cov ntawv thov uas siv cov hlau nplaum neodymium nyob rau hauv lub cev muaj zog lossis lub tshuab hluav taws xob, cov hluav taws xob yuav tshwm sim los ntawm cov txhuam hniav lossis cov neeg sib cuag. Qhov no tsis yog vim cov hlau nplaum lawv tus kheej, tab sis yog qhov tam sim no dhau los ntawm cov khoom siv hluav taws xob. Yog hais tias cov hlau nplaum yog ib feem ntawm lub kaw lus uas arcing tshwm sim, sparks yuav tshwm sim, tab sis qhov no yog ib qho teeb meem tsis cuam tshuam rau cov hlau nplaum cov khoom sib nqus.
3. Demagnetization: Yog tias cov hlau nplaum neodymium raug kub hnyiab lossis kev ntxhov siab ntawm lub cev, nws yuav plam nws cov khoom sib nqus. Qee zaum, qhov demagnetization no tuaj yeem ua rau kev tso tawm ntawm lub zog uas tuaj yeem pom tau tias yog lub txim hluav taws xob tab sis tsis yog qhov tshwm sim ncaj qha ntawm cov khoom siv ntawm cov hlau nplaum.
Kev Ceeb Toom
Thaum cov hlau nplaum neodymium muaj kev nyab xeeb nyob rau hauv ntau daim ntawv thov, lawv yuav tsum tau saib xyuas. Lawv cov hlau nplaum muaj zog tuaj yeem ua rau raug mob yog cov ntiv tes lossis lwm yam hauv lub cev raug ntes ntawm cov hlau nplaum. Tsis tas li ntawd, thaum ua haujlwm nrog cov hlau nplaum neodymium loj, ib tus yuav tsum paub txog qhov muaj peev xwm ntawm cov neeg kho tshuab cuam tshuam uas tuaj yeem ua rau muaj txim.
Nyob rau hauv ib puag ncig uas muaj cov ntaub ntawv flammable, nws raug nquahu kom tsis txhob muaj qhov xwm txheej uas cov hlau nplaum raug kev sib tsoo lossis kev sib txhuam. Kev ntsuas kev nyab xeeb tsim nyog yuav tsum tau ua txhua lub sijhawm thaum tuav cov hlau nplaum muaj zog.
