Maginito a Neodymium ndi maginito abwino kwambiri osasinthika omwe amagulitsidwa kulikonse padziko lapansi. kukana demagnetization posiyanitsa ndi ferrite, alnico komanso maginito a samarium-cobalt.
✧ Neodymium maginito VS maginito ochiritsira ferrite
Maginito a Ferrite ndi maginito omwe si achitsulo opangidwa ndi triiron tetroxide (chiwerengero chokhazikika cha iron oxide kupita ku ferrous oxide). Choyipa chachikulu cha maginitowa ndikuti sangathe kupangidwa mwakufuna kwawo.
Maginito a Neodymium samangokhala ndi mphamvu yabwino kwambiri ya maginito, komanso ali ndi mphamvu zabwino zamakina chifukwa cha kusakanikirana kwa zitsulo, ndipo amatha kusinthidwa mosavuta kukhala mawonekedwe osiyanasiyana kuti agwirizane ndi zosowa zosiyanasiyana. Choyipa chake ndichakuti ma monomers achitsulo omwe ali mu maginito a neodymium ndi osavuta kuchita dzimbiri ndikuwonongeka, kotero pamwamba pake nthawi zambiri amapakidwanso ndi nickel, chromium, zinc, tin, ndi zina zotero kuti apewe dzimbiri.
✧ Mapangidwe a neodymium maginito
Maginito a Neodymium amapangidwa ndi neodymium, chitsulo ndi boron ophatikizidwa pamodzi, nthawi zambiri amalembedwa ngati Nd2Fe14B. Chifukwa cha mawonekedwe osasunthika komanso kuthekera kopanga makristalo a tetragonal, maginito a neodymium amatha kuganiziridwa kuchokera kumalingaliro amankhwala. 1982, Makoto Sagawa wa Sumitomo Special Metals anapanga maginito a neodymium kwa nthawi yoyamba. Kuyambira pamenepo, maginito a Nd-Fe-B achotsedwa pang'onopang'ono ku maginito a ferrite.
✧ Kodi maginito a neodymium amapangidwa bwanji?
CHOCHITA 1- Choyamba, zinthu zonse zopangira mtundu wosankhidwa wa maginito zimayikidwa mu ng'anjo ya vacuum cleaner induction ng'anjo, yotenthetsera komanso yosungunuka kuti apange chinthu cha alloy. Kusakaniza kumeneku kumaziziritsidwa kuti apange ma ingots asanasinthidwe kukhala timbewu tating'ono mu mphero ya jeti.
CHOCHITA 2- ufa wapamwamba kwambiri umakanizidwa mu nkhungu komanso nthawi yomweyo mphamvu ya maginito imagwiritsidwa ntchito pa nkhungu. Magnetism amachokera ku chingwe chachitsulo chomwe chimakhala ngati maginito pamene mphamvu yamagetsi idutsamo. Pamene tinthu chimango cha maginito chikufanana ndi malangizo a maginito, izi zimatchedwa anisotropic maginito.
CHOCHITA 3- Uku sikumathero kwa njirayi, m'malo mwake, pakadali pano zinthu zomwe zili ndi maginito zimakhala zopanda maginito ndipo zidzapangidwanso ndi maginito pambuyo pake. Chotsatira ndichoti chinthucho chitenthedwe, mpaka chisungunuke munjira yotchedwa Chotsatira ndichoti chinthucho chitenthedwe, pafupifupi mpaka chisungunuke munjira yotchedwa sintering yomwe imapangitsa kuti maginito a ufa agwirizane. Mchitidwewu umachitika pamalo opanda okosijeni, opanda mpweya.
CHOCHITA 4- Pafupifupi pamenepo, zinthu zotenthedwa zimatsitsidwa mwachangu pogwiritsa ntchito njira yotchedwa kuzimitsa. Kuzizira kofulumiraku kumachepetsa madera a maginito oyipa komanso kumawonjezera magwiridwe antchito.
CHOCHITA 5- Chifukwa chakuti maginito a neodymium ndi olimba kwambiri, zomwe zimapangitsa kuti awonongeke mosavuta, amafunika kuphimbidwa, kutsukidwa, kuumitsidwa, komanso kupakidwa. Pali mitundu yosiyanasiyana ya maginito omwe amagwiritsidwa ntchito ndi maginito a neodymium, imodzi mwazofala kwambiri ndi kusakaniza kwa nickel-copper-nickel koma amatha kuphimbidwa ndi zitsulo zina komanso rabara kapena PTFE.
CHOCHITA6- Ikangophwanyidwa, chinthu chomalizidwacho chimapangidwanso ndi maginito pochiyika mkati mwa koyilo, yomwe, mphamvu yamagetsi ikadutsa imapanga mphamvu ya maginito katatu kuposa kulimba kofunikira kwa maginito. Iyi ndi njira yothandiza kwambiri kuti maginito ikapanda kusungidwa pamalopo, imatha kuponyedwa kuchokera pa koyilo ngati chipolopolo.
AH MAGNET ndi IATF16949, ISO9001, ISO14001 ndi ISO45001 yopanga mitundu yonse ya maginito a neodymium apamwamba komanso maginito omwe ali ndi zaka zopitilira 30 pantchitoyi. Ngati mukufuna maginito a neodymium, chonde omasuka kulankhula nafe!
