Kodi maginito a neodymium amakhala nthawi yayitali bwanji?

Maginito a NdFeB, omwe amadziwikanso kuti maginito a NdFeB, ndi maginito a tetragonal opangidwa ndi neodymium, iron, ndi boron (Nd2Fe14B). Maginito a Neodymium ndiye maginito osatha omwe alipo masiku ano komanso maginito omwe amagwiritsidwa ntchito kwambiri padziko lapansi.

Kodi maginito a maginito a NdFeB amatha nthawi yayitali bwanji?

Maginito a NdFeB ali ndi mphamvu yokakamiza kwambiri, ndipo sipadzakhalanso demagnetization ndi kusintha kwa maginito pansi pa chilengedwe ndi zinthu zambiri za maginito. Poganiza kuti chilengedwe ndi cholondola, maginito sataya ntchito zambiri ngakhale atagwiritsidwa ntchito nthawi yayitali. Chifukwa chake mukugwiritsa ntchito, nthawi zambiri timanyalanyaza chikoka cha nthawi pa magnetism.

Ndi zinthu ziti zomwe zingakhudze moyo wautumiki wa maginito a neodymium pakugwiritsa ntchito maginito tsiku lililonse?

Pali zinthu ziwiri zomwe zimakhudza moyo wautumiki wa maginito.

Choyamba ndi kutentha. Onetsetsani kuti mukulabadira vutoli pogula maginito. Maginito amtundu wa N amagwiritsidwa ntchito kwambiri pamsika, koma amatha kugwira ntchito pamalo ochepera madigiri 80. Ngati kutentha kupitirira kutentha uku, maginito adzakhala ofooka kapena demagnetized kwathunthu. Popeza mphamvu ya maginito yakunja ya maginito imafika pakuchulukira ndipo imapanga mizere yowonjezereka ya maginito, pamene kutentha kwakunja kumakwera, mawonekedwe oyenda nthawi zonse mkati mwa maginito amawonongeka. Zimachepetsanso mphamvu yokakamiza ya maginito, kutanthauza kuti, chinthu chachikulu cha maginito champhamvu chimasintha ndi kutentha, ndipo zomwe zimapangidwa ndi mtengo wofanana wa Br ndi mtengo wa H zimasinthanso moyenera.

Chachiwiri ndi dzimbiri. Nthawi zambiri, pamwamba pa maginito a neodymium padzakhala ndi zokutira. Ngati zokutira pa maginito zowonongeka, madzi amatha kulowa mkati mwa maginito mwachindunji, zomwe zingapangitse kuti maginito achite dzimbiri ndipo kenako kuchititsa kuchepa kwa maginito. Pakati pa maginito onse, mphamvu yokana dzimbiri ya maginito a neodymium ndi apamwamba kuposa maginito ena.

Ndikufuna kugula maginito a neodymium a moyo wautali, ndiyenera kusankha bwanji wopanga?

Maginito ambiri a neodymium amapangidwa ku China. Ngati mukufuna kugula zinthu zapamwamba, zimatengera mphamvu ya fakitale. Pankhani yaukadaulo wopanga, zida zoyezera, kuyenda kwa njira, thandizo laukadaulo, dipatimenti ya QC ndi satifiketi yoyang'anira kasamalidwe kabwino zonse zimatha kukwaniritsa miyezo yapadziko lonse lapansi. Fuzheng amangokwaniritsa zonse zomwe zili pamwambapa, choncho ndi bwino kutisankha ife monga opanga maginito a neodymium aakazi.
