Bonded NdFeB (NdFeB) yog cov khoom siv hlau nplaum uas muaj zog tshaj plaws nyob rau tam sim no. Nws muaj qhov zoo ntawm kev ua kom muaj zog ntom ntom, muaj cov khoom sib nqus siab, thiab lwm yam cuab yeej siv hluav taws xob, cov tsheb hluav taws xob, khoom siv hluav taws xob thiab lwm daim teb. Ntawm lawv, nias thiab txhaj tshuaj molding ntawm bonded NdFeB yog ob qho kev npaj ua ntej. Hauv qab no, peb yuav qhia tshwj xeeb txog qhov sib txawv ntawm ob txoj haujlwm no.
Ua ntej, cov txheej txheem ntws ntawm kev sib raug zoo NdFeB nias yog qhov yooj yim thiab tus nqi qis. Nws cov txheej txheem tseem ceeb suav nrog: kev npaj cov hmoov sib nqus, sib tov, nias, sintering annealing, thiab lwm yam. Nyob rau hauv cov txheej txheem nias, isostatic pressing tshuab feem ntau yog siv, uas yog, los ntawm kev teeb tsa lub siab thiab lub sij hawm, lub bonded NdFeB magnetic hmoov yog nias rau hauv ib dawb paug nrog tej yam magnetic zog thiab sab nraud qhov ntev. Cov txheej txheem nias no tsim nyog rau kev npaj cov hlau nplaum tas mus li nrog cov duab yooj yim, qhov ntev ruaj khov thiab qhov yuav tsum tau ua kom tsawg.
Qhov thib ob, kev txhaj tshuaj molding txheej txheem ntawm kev sib raug zoo NdFeB yuav tsum tau tshwj xeeb txhaj tshuaj molding khoom thiab pwm, thiab tus nqi kuj yog siab heev. Cov txheej txheem txhaj tshuaj molding feem ntau suav nrog: kev sib tsoo zoo, sib tov, txhaj tshuaj, sintering annealing, thiab lwm yam. Ntawm lawv, kev txhaj tshuaj molding yog qhov txuas tseem ceeb ntawm kev txhaj tshuaj molding txheej txheem. Tsis zoo li cov txheej txheem nias, thaum lub sij hawm txhaj tshuaj molding txheej txheem, lub bonded NdFeB magnetic hmoov yuav tsum tau tag nrho tov nrog cov binder nyob rau hauv lub siab thiab kub kub los ua ib tug slurry nrog zoo fluidity, thiab ces ncaj qha txhaj rau hauv pwm rau molding. Cov txheej txheem txhaj tshuaj molding yog tsim nyog rau cov hlau nplaum ruaj khov nrog cov duab nyuaj, qhov ntev, thiab cov khoom sib nqus ruaj khov.
Feem ntau, txawm hais tias qhov sib koom ua ke NdFeB nias molding thiab txhaj tshuaj molding yog qhov sib txawv hauv cov txheej txheem, lawv ob leeg muaj qee qhov zoo thiab daim ntawv thov. Qhov kev xaiv ntawm cov txheej txheem yuav tsum nyob ntawm cov kev xav tau tshwj xeeb. Nyob rau tib lub sijhawm, tsis hais cov txheej txheem twg yog siv, cov kws tshaj lij cov neeg ua haujlwm, cov khoom siv raw khoom zoo thiab kev tswj hwm nruj nruj yuav tsum tau ua kom ntseeg tau tias qhov zoo thiab ua haujlwm ntawm cov hlau nplaum ruaj khov NdFeB.
