Cob phum ntawm cov hlau nplaum thiab lub ntiaj teb tsawg
Lub ntiaj teb tsawg tsawg muaj 15 ntsiab lus ntawm lanthanides, ntxiv rau 17 yam uas tau hais txog lanthanides. Lawv yog: La , Ce, Pr, Nd, Pm, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu
Ib qho tseem ceeb ntawm cov haujlwm tseem ceeb yog cov hlau nplaum, Nd.
Cov neeg siv loj ntawm cov ntoo crucibles yog cov ntaub ntawv Magnet NdFeB. Lub advent ntawm NdFeB tas li hlau nplaum tau txhaj cov kev cai tshiab thiab kev loj hlob mus rau hauv lub ntiaj teb tsis tshua muaj siab-tech. NdFeB hlau nplaum muaj lub zog sib nqus hluav taws xob thiab muaj lub npe hu ua "tus vaj ntxwv ntawm cov hlau nplaum" nyob rau tam sim no. Lawv tau siv rau hauv tshuab hluav taws xob, machinery thiab lwm yam lag luam rau lawv cov kev ua tau zoo.
Cob phum ntawm cov lag luam "permanent Neuterium-Iron-Boron" ua kom muaj kev sib txuas sib nqus. Nrog tu tsis pub dawb, muaj zog dag zog, lub neej ntev, kev yooj yim installation, ib qho yooj yim mus use, txhim khu kev lag luam thiab lwm yam. Nws yog tsim rau tshem cov hlau tawm ntawm cov khoom tsis muaj hlau nplaum rau ntawm cov neeg siv thauj khoom, vibratory conveyors, electromagnetic vibrating feeders thiab chutes.
Tshem tawm 0.1-35 kg ntawm ferromagnetic cov khoom, lub hauv paus ruaj khov nqus hlau pab lub neej ntawm ntau tshaj 10 xyoo. Thaum cov hlau nplaum tas mus li los ntawm cov khoom siv ferromagnetic ntau heev, lawv muab tshem tawm nrog lub pob hlau uas tsis yog hlau nplaum lossis tshem tawm cov hnab looj tes. Qhov no yog tsim rau cov kev siv rau qhov kev lag luam uas nruam thiab hlau tsawg.
