Yuav ua li cas NdFeB sib sib zog nqus cov xeb hluav taws xob
Kev sib txhuam yog siv hauv ntau lub lag luam, thiab nws tsis yog kos rau hauv NdFeB qhov kev lag luam hlau vim NdFeB hlau nplaum raug rau corrosion. Yog li, feem ntau ntawm cov khoom tiav yog electroplated los yog pleev xim rau. Cov kev kho hniav dav dav xws li: nickel plating (xim nickel tooj liab nickel), galvanizing, txhuas plating, electrophoresis, thiab cov zoo li. Yog tias ua haujlwm hauv ib cheeb tsam kaw, phosphating kuj tseem siv tau.
Cov txheej txheem los tiv thaiv kev kub ntxhov ntawm NdFeB hlau nplaum
NdFeB magnetism yog ib qho khoom siv hlau nplaum uas siv dav thiab tsim tau sai heev. NdFeB tau dav siv txij li nws qhov tsim muaj, tab sis nws tau ntau tshaj 20 xyoo. Vim nws cov khoom sib nqus sib nqus thiab yooj yim ntawm cov khoom, tus nqi tsis siab heev, yog li ntawd daim teb ntawv yog nthuav dav heev. Tam sim no, cov lag luam NdFeB, cov khoom sib nqus zog tuaj yeem ncav cuag 50MGOe, uas yog 10 npaug ntawm ferrite.
Muab piv nrog cov khoom ntiag tug xws li ferrite, NdFeB magnet muaj cov khoom sib nqus zoo heev. Nws cov khoom sib nqus zog yog ntau tshaj li lwm cov hlau nplaum, thiab nws muaj peev xwm raug hu ua "ib tiam neeg sib txeeb". NdFeB hlau nplaum muaj qhov kub ntxhov siab heev tshaj plaws (Bs = 16KGs) thiab ib qho magnetocrystalline anisotropy field HA (HA = 73KOe). NdFeB cov khoom siv hlau nplaum yog siv rau hauv cov khoom ntim, cov khoom ua si, khoom plig khoom siv, cov khoom fais fab muaj zog. Cov tsheb, cov cav ntoo, cov tshuab hluav taws xob, cov tshuab computer, cov twj paj nruag, ntsuas lub cev, cov khoom siv phom, cov koob yees duab, cov suab, cov cuab yeej siv hauv tsev, chaw ua haujlwm automation, kev kho cov hlau nplaum, thiab lub neej txhua hnub.
NdFeB magnetism kuj yog cov khoom ua hmoov hlau metallurgy, thiab txoj kev ua haujlwm zoo ib yam li cov kabmob samarium. Tam sim no, qhov siab tshaj ntawm kev kub ntxhov ntawm NdFeB yog nyob 180 degrees Celsius. Yog tias nws yog ib qho chaw nyaum heev, nws feem ntau xav kom tsis pub dhau 140 degrees Celsius.
Qhov saum toj no yog txheej txheem los tiv thaiv cov hlau hluav taws xob ntawm NdFeB hlau nplaum uas peb tau qhia rau txhua tus neeg. Vim yog cov khoom sib nqus ntawm NdFeB, feem ntau, nws yog siv los hloov lwm cov khoom sib nqus los txo cov ntim ntawm cov khoom. Yog tias koj siv ferrite cov hlau nplaum, qhov luaj li cas ntawm tus xov tooj, kuv ntshai nws yuav tsis tsawg tshaj li ib nrab ntawm ib qho av ci.
