Tuam Tshoj OEM Pheej Yig Ring Ferrite Magnet Hoobkas

Txheej txheem cej luam

Cov hlau nplaum ruaj khov ferrite, tseem hu ua cov hlau nplaum tawv, yog cov khoom siv hlau nplaum uas tsis yog xim hlau.In 1930, Kato thiab Wujing nrhiav tau ib hom spinel (MgA12O4) cov hlau nplaum ruaj khov, uas yog cov qauv ntawm ferrite dav siv niaj hnub no. Ferrite hlau nplaum feem ntau yog tsim. SrO los yog Bao thiab Fe2O3 ua raw khoom los ntawm cov txheej txheem ceramic (pre firing, crushing, pulverizing, pressing, sintering thiab sib tsoo).Nws muaj cov yam ntxwv ntawm dav hysteresis voj, siab coercive quab yuam thiab siab remanence.Nws yog ib yam khoom siv ua haujlwm uas tuaj yeem khaws cov hlau nplaum tas li ib zaug magnetized.Nws qhov ceev yog 4.8g / cm3.Raws li cov txheej txheem ntau lawm, ferrite hlau nplaum tuaj yeem muab faib ua ob hom: sintering thiab bonding.Sintering tuaj yeem muab faib ua kom qhuav thiab ntub nias, thiab kev sib txuas tuaj yeem muab faib ua extrusion, compression thiab txhaj tshuaj molding.Cov mos mos, elastic thiab twisted hlau nplaum ua los ntawm bonded ferrite hmoov thiab hluavtaws roj hmab kuj hu ua roj hmab hlau nplaum.Raws li seb cov hlau nplaum sab nraud yog siv los yog tsis, nws tuaj yeem muab faib ua isotropic ruaj khov hlau nplaum thiab anisotropic ruaj khov hlau nplaum.

Sib piv nrog lwm cov khoom sib nqus

Qhov zoo:Tus nqi qis, qhov dav ntawm cov ntaub ntawv raw, kub tsis kam (txog 250 ℃) thiab corrosion kuj.

Disadvantage: Piv nrog NdFeB cov khoom, nws remanence tsawg heev.Tsis tas li ntawd, vim yog cov qauv xoob thiab tsis yooj yim ntawm nws cov khoom siv tsawg, ntau txoj kev ua haujlwm raug txwv los ntawm nws, xws li xuas nrig ntaus, khawb, thiab lwm yam., feem ntau ntawm nws cov khoom zoo tuaj yeem tsuas yog nias los ntawm pwm, cov khoom. kam rau ua qhov tseeb yog qhov tsis zoo, thiab tus nqi pwm yog siab.

Txheej:Vim nws zoo heev corrosion kuj, nws tsis xav tau txheej tiv thaiv.
