  • Maginito a Ferrite

    Kufotokozera Kwachidule:

    Ma ferrites ovuta kutengera barium ferrite ndi strontium powders (mankhwala a BaO • 6Fe2O3 ndi SrO • 6Fe2O3) opangidwa. Amakhala ndi zitsulo zowonjezera, zomwe zimaphatikizidwira mgulu lazinthu zopangira ceramic. Amakhala pafupifupi. 90% iron oxide (Fe2O3) ndi 10% alkaline lapansi oxide (BaO kapena SrO) - zopangira zomwe ndizochuluka komanso zotsika mtengo. Amagawika mu isotropic ndi anisotropic, tinthu totsatirazi timagwirizana chimodzi
    malangizo omwe akupeza maginito abwino. Maginito a Isotropic amapangidwa ndi kuponderezana pomwe maginito a anisotropic amaponderezedwa mkati mwa maginito. Izi zimapatsa maginito mayendedwe osankhika ndikuwonjezera mphamvu yake katatu.

     Zindikirani:
    · Tikhalabe ofanana ndi pamwambapa pokhapokha titanenedwa kuchokera kwa kasitomala. Kutentha kwa curie ndi koyefishienti yakutengera ndi yongotchula kokha, osati ngati maziko osankhira.

    Mwayi:

    Monga momwe zimapangidwira ma oxide, maginito olimba a ferrite amawonetsa mawonekedwe osagwirizana ndi chinyezi, zosungunulira, mayankho amchere,

    asidi ofooka, mchere, mafuta ndi zoyipitsa za gasi. Nthawi zambiri maginito olimba a ferrite amatha kugwiritsidwa ntchito popanda kutetezedwa ndi dzimbiri.
    Mbali:
    Chifukwa cha kuuma kwawo kwakukulu (6-7 Mohs), maginito a Ferrite ndiwopepuka komanso amazindikira kugogoda kapena kupindika. Pakukonzekera, amayenera kupangidwa ndi zida za diamondi. Kutentha kogwiritsa ntchito maginito a ferrite nthawi zambiri amakhala pakati pa -40ºC ndi 250ºC.

    Ntchito:

    Maonekedwe osiyanasiyana amagwiritsidwa ntchito popanga magalimoto, monga makina osinthira komanso kuyeza. Ntchito zina monga Makina yamagalimoto yamagalimoto (zopukuta, mpando wamagalimoto), Kuphunzitsa, zotengera zitseko, njinga yamaginito ndi mpando wa kutikita minofu, ndi zina zambiri.

     

    Masiku ano, ma ferrites olimba amaimira gawo lalikulu kwambiri la maginito okhazikika omwe amapangidwa. Mosiyana ndi maginito a AlNiCo, ma ferrites olimba amadziwika ndi kuchepa kwamphamvu koma mphamvu yolimbikira. Izi zimapangitsa kuti zinthuzo zizikhala zosalala. Barium ferrite ndi strontium ferrite amasiyanitsidwa kutengera zinthu zoyambira.

    Malingaliro onse adatsimikizika pogwiritsa ntchito zitsanzo zofananira malinga ndi IEC 60404-5. Zotsatirazi zikugwiritsidwa ntchito ngati zowunikira ndipo zitha kusiyanasiyana.
