Hom tau tsam:
Raws li ib txwm muaj ntawm oxide ceramics, nyuaj ferrite hlau nplaum tso tawm tus cwj pwm tsis kam tiv thaiv kev ya raws, ya raws, cov kev hais daws teeb meem,
cov kua qaub tsis muaj zog, ntsev, lub roj thiab cov pa paug. Feem ntau, cov hlau nplaum tawv hlau khov tuaj yeem siv tau yam tsis muaj kev tiv thaiv kev xeb ntxiv.
Nta:
Vim lawv qhov kev ua haujlwm nyuaj (6-7 Mohs), Ferrite cov hlau nplaum yog nkig thiab rhiab los tsoo lossis khoov. Thaum lub sijhawm ua haujlwm, lawv yuav tsum tau muab cov tshuab nrog pob zeb diamond cuab yeej. Kev khiav hauj lwm kub nrog ferrite hlau nplaum feem ntau yog nruab nrab ntawm –40ºC txog 250ºC.
Daim ntawv thov:
Cov duab sib txawv siv rau hauv kev tsim kho tsheb, xws li kev siv tshuab thiab ntsuas ntsuas. Lwm yam kev siv xws li Kev Siv Lub Tshuab Hluav Taws Xob (wipers, zaum lub rooj zaum lub cev muaj zog), Kev Qhia, Lub qhov rooj nqus, Qhov nqus tsheb kauj vab thiab lub rooj zaum zaws, thiab lwm yam
Niaj hnub no, cov ferrites nyuaj sawv cev rau kev faib ua feem ntau ntawm cov hlau nplaum tas mus li. Hauv kev sib piv rau AlNiCo hlau nplaum, tawv ferrites yog tus yam ntxwv los ntawm flux densities tab sis siab coercive teb lub zog. Qhov no ua rau qhov feem ntau tiaj tiaj ntawm cov ntaub ntawv. Barium ferrite thiab strontium ferrite tau sib txawv raws li cov khoom pib.
Txhua qhov tau tshaj tawm tau txiav txim siab siv tus qauv coj mus kuaj raws li IEC 60404-5. Cov lus qhia tshwj xeeb hauv qab no ua qhov tseem ceeb siv thiab yuav txawv.
