Nrog rau txoj kev loj hlob ntawm kev lag luam niaj hnub no, daim ntawv thov ntawm NdFeB hlau nplaum yog dav thiab dav, tshwj xeeb tshaj yog nyob rau hauv lub teb ntawm hluav taws xob, machinery, electronics, computers, thiab lwm yam, thiab nws tau dhau los ua ib qho ntawm cov khoom tseem ceeb ntawm cov khoom sib nqus ntawm lub khw . Txawm li cas los xij, hauv kev tsim khoom tiag tiag, vim tias tsis muaj kev kho saum npoo zoo, kev ua haujlwm ntawm cov hlau nplaum tsis tuaj yeem tso tawm tag nrho. Yog li ntawd, kev kho kom zoo yog ib txoj hauv kev tseem ceeb kom tswj tau qhov zoo ntawm NdFeB hlau nplaum. Kab lus no yuav pib los ntawm "cov hlau nplaum NdFeB sib raug zoo" thiab qhia qee txoj kev kho saum npoo.
Rationally xaiv oxide txheej kev kho mob: Txoj kev no plays lub luag hauj lwm nyob rau hauv kom tsis txhob muaj kev sib raug zoo tsis zoo tsis muaj magnification, ua rau nws ntau zog. Thaum kho cov txheej txheem oxide, nws yog qhov yuav tsum tau ua ntej degrease thiab ntxuav nws, tom qab ntawd ua cov phosphating kev kho mob, thiab thaum kawg ua oxidation kev kho mob los ua ib zaj duab xis oxide.
Siv txoj kev kho electroplating: Txoj kev no tuaj yeem tsim cov txheej txheem tiv thaiv corrosion ntawm cov hlau nplaum, uas tuaj yeem tiv thaiv cov hlau nplaum los ntawm oxidized. Electroplating tshuab yog los ua phaj txheej txheej ntawm cov khoom siv hlau los yog hlau ntawm cov hlau nplaum, thiab nws tuaj yeem ntxiv xim rau saum npoo ntawm cov hlau nplaum.
Siv cov plua plav adsorption txheej: Txoj kev no tsim cov txheej txheem adsorption ntawm cov hlau nplaum rau adsorb plua plav thiab av, thiaj li ua kom muaj kev huv thiab huv ntawm cov hlau nplaum nto.
Kev txiav thiab polishing txoj kev: Kev kho deg ntawm cov hlau nplaum yog ze ze rau polishing, vim tias cov txheej txheem ua haujlwm tuaj yeem ua rau cov khoom siv tshuaj lom neeg ntawm nws qhov chaw, ua rau lub ntsej muag roughness ntawm cov hlau nplaum nce, cuam tshuam rau kev tiv thaiv kev sib nqus thiab cov zoo ntawm kev sib koom ua ke, thiab kuj yooj yim txo qhov saturation magnetization siv ntawm cov khoom ferromagnetic. Kev txiav thiab polishing tuaj yeem tsis tsuas yog ua kom lub ntsej muag roughness, tab sis kuj nce qhov smoothness ntawm cov khoom sib nqus, yog li txhim kho lub xeev ntawm cov khoom sib nqus.
