Maginito a Neodymium ndi maginito abwino kwambiri osinthika omwe amagulitsidwa kulikonse padziko lapansi, omwe amalimbana ndi demagnetization poyerekeza ndi maginito a ferrite, alnico komanso samarium-cobalt.
✧ Maginito a Neodymium vs maginito a ferrite achikhalidwe
Maginito a Ferrite ndi maginito osakhala achitsulo omwe amachokera ku triiron tetroxide (chiŵerengero chokhazikika cha chitsulo chosakanizika ndi ferrous oxide). Vuto lalikulu la maginito awa ndilakuti sangapangidwe momwe akufunira.
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.
✧ Kapangidwe ka maginito a neodymium
Maginito a Neodymium amapangidwa ndi neodymium, chitsulo ndi boron zomwe zimagwirizanitsidwa pamodzi, nthawi zambiri zimalembedwa kuti Nd2Fe14B. Chifukwa cha kapangidwe kake kokhazikika komanso kuthekera kopanga makhiristo a tetragonal, maginito a neodymium amatha kuonedwa ngati mankhwala okha. 1982, Makoto Sagawa wa Sumitomo Special Metals adapanga maginito a neodymium koyamba. Kuyambira pamenepo, maginito a Nd-Fe-B achotsedwa pang'onopang'ono kuchokera ku maginito a ferrite.
✧ Kodi maginito a neodymium amapangidwa bwanji?
GAWO 1- Choyamba, zinthu zonse zopangira maginito osankhidwa zimayikidwa mu uvuni wa vacuum cleaner, zimatenthedwa komanso zimasungunuka kuti zipange chinthu chopangidwa ndi alloy. Kenako kusakaniza kumeneku kumaziziritsidwa kuti kupange ma ingot asanayambe kuphwanyidwa kukhala tinthu tating'onoting'ono mu jet mill.
GAWO LACHIWIRI- Ufa wabwino kwambiri umakanikizidwa mu nkhungu ndipo nthawi yomweyo mphamvu ya maginito imayikidwa pa nkhunguyo. Magnetism imachokera ku chingwe chomwe chimagwira ntchito ngati maginito pamene magetsi adutsamo. Pamene tinthu tating'onoting'ono ta maginito tikugwirizana ndi malangizo a maginito, izi zimatchedwa maginito anisotropic.
GAWO 3- Iyi si mapeto a njirayi, m'malo mwake, pakadali pano zinthu zomwe zili ndi maginito zimachotsedwa mphamvu ya maginito ndipo zidzasinthidwa mphamvu ya maginito pambuyo pake. Gawo lotsatira ndikuti zinthuzo zitenthedwe, pafupifupi mpaka kufika posungunuka mu njira yotchedwa Chochita chotsatirachi ndikuti chinthucho chitenthedwe, pafupifupi mpaka kufika posungunuka mu njira yotchedwa sintering yomwe imapangitsa kuti maginito a ufa azigwirizana. Njirayi imachitika popanda mpweya, komanso yopanda mpweya.
GAWO 4- Pafupifupi pamenepo, zinthu zotenthedwa zimazizidwa mofulumira pogwiritsa ntchito njira yotchedwa kuzimitsa. Njira yoziziritsira mofulumirayi imachepetsa madera omwe ali ndi maginito oipa komanso imawonjezera magwiridwe antchito.
GAWO 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.
STEPI 6- Akangoyika, chinthu chomalizidwacho chimapangidwanso ndi maginito pochiyika mkati mwa coil, yomwe, magetsi akadutsa imapanga mphamvu ya maginito yoposa katatu mphamvu yofunikira ya maginito. Iyi ndi njira yothandiza kwambiri kotero kuti ngati maginito sasungidwa pamalopo amatha kuponyedwa kuchokera mu coil ngati chipolopolo.
AH MAGNET ndi kampani yodziwika bwino ya IATF16949, ISO9001, ISO14001 ndi ISO45001 yopanga mitundu yonse ya maginito a neodymium ogwira ntchito bwino komanso maginito okhala ndi zaka zoposa 30 akugwira ntchito imeneyi. Ngati mukufuna maginito a neodymium, chonde musazengereze kutilankhulana nafe!
