Cov Hlau Nkaus Loj Neodymium Disc - Kev Dais Teeb Meem | Fullzen

Cov hlau nplaum neodymium loj tshaj plaws uas muaj tam sim no feem ntau yog ua los ntawm daim ntawv ntawm lub hlau nplaum thaiv lossis disc, nrog rau qhov ntev thiab dav txij li ob peb nti mus txog ob peb nti. Cov hlau nplaum neodymium loj dua no muaj peev xwm muaj lub zog rub hlau nplaum loj heev thiab siv rau hauv ntau yam kev siv xws li cov khoom siv hauv kev lag luam, cov khoom sib cais hlau nplaum, cov cav, thiab cov tshuab hluav taws xob. Txawm hais tias tsis muaj qhov txwv qhov loj me rau cov hlau nplaum neodymium, nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias thaum qhov loj me nce ntxiv, lub zog hlau nplaum ntawm cov hlau nplaum yuav txo qis. Qhov no yog vim tias cov hlau nplaum loj dua yuav muaj feem ntau dua ntawm cov cheeb tsam hlau nplaum sab hauv uas tshem tawm ib leeg, txo lawv lub zog tag nrho ntawm lub zog hlau nplaum. Txawm li cas los xij, kev nce qib hauv kev tsim cov hlau nplaum tau tso cai rau kev tsim cov hlau nplaum neodymium loj dua nrog cov khoom sib nqus zoo dua.

Cov hlau nplaum neodymium disc, tseem hu ua cov hlau nplaum puag ncig neodymium lossis cov hlau nplaum neodymium lub tog raj kheej, yog cov hlau nplaum me me uas zoo li lub cylindrical ua los ntawm neodymium-iron-boron (NdFeB) alloy. Lawv yog cov hlau nplaum ruaj khov muaj zog tshaj plaws hauv kev lag luam. Cov hlau nplaum no feem ntau ua rau hauv cov duab disc, qhov twg txoj kab uas hla loj dua qhov siab (tuab), ua rau cov duab puag ncig tiaj tus. Lawv muaj ntau qhov ntau thiab tsawg, nrog rau txoj kab uas hla thiab tuab txij li ob peb millimeters mus rau ob peb nti. Vim lawv lub zog sib nqus siab, cov hlau nplaum neodymium disc siv dav hauv ntau yam kev siv, suav nrog cov khoom siv hluav taws xob, cov khoom siv kho mob, kev lag luam tsheb, kev ua tes ua taw thiab cov haujlwm nyiam ua si, kev kaw hlau nplaum, cov hniav nyiaj hniav kub sib nqus, thiab txawm tias hauv kev sim sib nqus. Vim lawv qhov me me thiab lub zog sib nqus, lawv yuav tsum tau ceev faj vim lawv tuaj yeem nyiam lossis thawb lwm yam khoom sib nqus thiab yuav ua rau raug mob yog tias tsis siv zoo.

Tus "N" hauv neodymium txhais tau tias yog lub cim tshuaj lom neeg ntawm cov khoom neodymium nws tus kheej. Neodymium (Nd) yog ib qho khoom tsis tshua muaj neeg nyob hauv lanthanide series ntawm lub rooj periodic. Nws tau muab lub npe los ntawm cov lus Greek "neos" txhais tau tias "tshiab" thiab "didymos" txhais tau tias "ntxaib," uas qhia txog nws qhov kev tshawb pom ua ib qho khoom ntxaib rau cov khoom uas tau paub yav dhau los, praseodymium. Neodymium yog siv dav hauv kev tsim cov hlau nplaum ruaj khov, zoo li cov hlau nplaum neodymium, vim nws cov khoom sib nqus siab. Cov khoom no pab txhawb rau lub zog sib nqus uas pom los ntawm cov hlau nplaum neodymium, ua rau lawv nrhiav tau hauv ntau yam kev siv uas xav tau lub zog sib nqus muaj zog.
