Magnet yog ib yam khoom tseem ceeb ntawm cov hlau xws li hlau, cobalt, thiab npib tsib xee. Nws muaj cov khoom sib nqus muaj zog thiab siv dav hauv txhua qhov chaw ntawm lub neej. Hauv qee qhov kev lag luam precision, cov hlau nplaum uas tuaj yeem tiv taus qhov kub thiab txias yog xav tau los ua kom tiav cov haujlwm tshwj xeeb. Yog li, yuav ua li cas qhia seb tus qauv hlau nplaum tiv taus qhov kub thiab txias? Wb tham txog qhov teeb meem hauv qab no.
Ua ntej, peb yuav tsum xav txog cov khoom siv ntawm cov khoom siv hlau nplaum. Feem ntau, cov khoom siv hlau nplaum tseem ceeb uas tuaj yeem tiv taus qhov kub thiab txias yog neodymium hlau boron, cobalt nyuaj hlau nplaum, cobalt alumina, thiab lwm yam. Qhov kub tsis kam ntawm cov ntaub ntawv no yuav txawv ntawm qhov chaw ua haujlwm sib txawv, tab sis tag nrho lawv kuj zoo heev. Tsis tas li ntawd, qee cov khoom siv hlau nplaum uas tsis tshua muaj nqi feem ntau siv cov khoom xws li hlau oxide rau doping. Qhov kub tsis kam ntawm cov khoom no feem ntau tsis zoo, thiab lawv yuav tsum tau ua tib zoo xav txog thaum siv.
Qhov thib ob, peb tuaj yeem sim txiav txim qhov ntsuas kub ntawm cov hlau nplaum los ntawm kev soj ntsuam nws qhov chaw. Feem ntau, qhov kub thiab txias ib puag ncig yuav ua rau qee yam corrosion thiab oxidation los ntawm cov ntaub ntawv hlau, uas ua rau qee qhov xeb, tsis muaj xim, thiab lwm yam ntawm qhov chaw. Yog tias peb pom cov phenomena nyob rau saum npoo ntawm cov hlau nplaum, nws txhais tau tias nws qhov kub thiab txias kuj yuav muaj teeb meem.
Thib peb, peb kuj tuaj yeem kuaj qhov ntsuas kub ntawm cov hlau nplaum los ntawm kev ua kom sov. Nyob rau hauv ib puag ncig kev sim, peb tuaj yeem muab cov qauv hlau nplaum tso rau hauv qhov cub kub thiab ua qhov ntsuas kub sib txawv. Yog tias cov hlau nplaum tseem tuaj yeem tswj hwm nws cov khoom qub sib nqus thiab cov khoom siv kho tshuab tom qab kev sim, nws txhais tau tias nws qhov kub thiab txias kuj yog qhov zoo.
Thaum kawg, peb yuav tsum tau xyuam xim rau qhov tseeb tias thaum siv cov khoom siv hlau nplaum, peb yuav tsum xaiv cov khoom tsim nyog raws li qhov xwm txheej tiag tiag. Yog tias peb yuav tsum siv cov hlau nplaum uas tuaj yeem tiv taus qhov kub thiab txias, peb yuav tsum ua tib zoo xyuas nws cov ntaub ntawv pov thawj cuam tshuam thaum yuav cov khoom, thiab sib txuas lus nrog cov chaw tsim khoom kom ntseeg tau tias cov khoom tuaj yeem ua tau raws li peb cov kev xav tau.
