Maginito a Neodymium ndi maginito a Hematite ndi zinthu ziwiri zodziwika bwino zamaginito, zomwe zimagwiritsidwa ntchito kwambiri m'magawo awo. Maginito a Neodymium ndi a Rare-earth magnet, omwe amapangidwa ndi neodymium, chitsulo, boron ndi zinthu zina. Ali ndi maginito amphamvu, mphamvu yayikulu komanso kukana dzimbiri, ndipo amagwiritsidwa ntchito kwambiri mu injini, jenereta, zida zamawu ndi zina. Maginito a Hematite ndi mtundu wa zinthu zamaginito zamtundu wa ore, zomwe zimapangidwa makamaka ndi hematite yokhala ndi miyala yachitsulo. Ali ndi mphamvu zamaginito zocheperako komanso zotsutsana ndi dzimbiri, ndipo amagwiritsidwa ntchito kwambiri muzinthu zamaginito zachikhalidwe, zida zosungira deta ndi zina.M'nkhaniyi, makhalidwe ndi ntchito za maginito a Neodymium ndi maginito a Hematite zidzakambidwa mozama, ndipo kusiyana kwawo kudzayerekezeredwa.

Makhalidwe ndi Kugwiritsa Ntchito Neodymium maginito:

A. Makhalidwe a maginito a Neodymium:

Kapangidwe ka mankhwala:Maginito a Neodymium amakhala ndi neodymium (Nd), chitsulo (Fe) ndi zinthu zina. Kuchuluka kwa neodymium nthawi zambiri kumakhala pakati pa 24% ndi 34%, pomwe kuchuluka kwa chitsulo kumakhala kwakukulu. Kuwonjezera pa neodymium ndi chitsulo, maginito a Neodymium angakhalenso ndi zinthu zina, monga boron (B) ndi zinthu zina zosadziwika bwino zapadziko lapansi, kuti akonze mphamvu zake zamaginito.

Mphamvu ya maginito:Maginito a Neodymium ndi amodzi mwa maginito amphamvu kwambiri amalonda omwe amadziwika pakali pano. Ali ndi maginito apamwamba kwambiri, omwe amatha kufika pamlingo womwe maginito ena sangafikire. Izi zimawapatsa mphamvu zabwino kwambiri zamaginito ndipo ndi oyenera kwambiri kugwiritsa ntchito zomwe zimafuna maginito ambiri.

Kukakamiza:Maginito a Neodymium ali ndi mphamvu yolimba kwambiri, zomwe zikutanthauza kuti ali ndi mphamvu yolimba ya maginito komanso kukana kudulidwa. Pogwiritsa ntchito, maginito a Neodymium amatha kusunga mphamvu yake ya maginito ndipo sakhudzidwa mosavuta ndi mphamvu yakunja ya maginito.

Kukana dzimbiri:Kukana dzimbiri kwa maginito a Neodymium nthawi zambiri kumakhala koipa, kotero kuchiza pamwamba, monga electroplating kapena kutentha, nthawi zambiri kumafunika kuti kukhale kolimba. Izi zitha kuonetsetsa kuti maginito a Neodymium sagwidwa ndi dzimbiri komanso okosijeni akagwiritsidwa ntchito.

B. Kugwiritsa ntchito maginito a Neodymium:

Mota ndi jenereta: Maginito a Neodymium amagwiritsidwa ntchito kwambiri mu injini ndi jenereta chifukwa cha maginito ake ambiri komanso mphamvu zake zokakamiza. Maginito a Neodymium amatha kupereka mphamvu yamphamvu ya maginito, kotero kuti maginito ndi majenereta azikhala ndi mphamvu komanso magwiridwe antchito apamwamba.

Zipangizo zamawu: Maginito a Neodymium amagwiritsidwanso ntchito muzipangizo zamawu, monga zokuzira mawu ndi mahedifoni. Mphamvu yake yamphamvu yamaginito imatha kutulutsa mawu ambiri komanso zotsatira zabwino za mawu. Zipangizo zachipatala: Maginito a Neodymium amagwiritsidwanso ntchito kwambiri muzipangizo zachipatala. Mwachitsanzo, muzipangizo zamaginito zojambulira maginito (MRI), maginito a Neodymium amatha kupanga mphamvu yamaginito yokhazikika ndikupereka zithunzi zapamwamba.

Makampani opanga ndege: Mu makampani opanga ndege, maginito a Neodymium amagwiritsidwa ntchito popanga makina owongolera ndi kulamulira ndege, monga gyroscope ndi zida zowongolera. Maginito ake amphamvu komanso kukana dzimbiri zimapangitsa kuti ikhale chisankho chabwino kwambiri.

Pomaliza, chifukwa cha kapangidwe kake ka mankhwala apadera komanso makhalidwe ake abwino kwambiri,Maginito a dziko lapansi osowa kwambiri a neodymiumimagwira ntchito yofunika kwambiri m'magawo osiyanasiyana ogwiritsira ntchito, makamaka m'makina amagetsi, zida zamawu, zida zamankhwala ndi makampani opanga ndege. Ndikofunikiranso kuonetsetsa kuti magwiridwe antchito ndi moyo waMaginito apadera a Neodymium, wongolerani kusintha kwa kutentha kwake ndikutenga njira zoyenera zopewera dzimbiri.

Ⅱ. Makhalidwe ndi Kugwiritsa Ntchito Maginito a Hematite:

A. Khalidwe la maginito a Hematite:

Kapangidwe ka mankhwala:Maginito a Hematite amapangidwa makamaka ndi miyala yachitsulo, yomwe ili ndi okusayidi yachitsulo ndi zinthu zina zodetsa. Kapangidwe kake ka mankhwala ndi Fe3O4, yomwe ndi okusayidi yachitsulo.

Mphamvu ya maginito: Maginito a Hematite ali ndi mphamvu ya maginito yocheperako ndipo ndi a zinthu zofooka zamaginito. Ngati pali mphamvu ya maginito yakunja, maginito a Hematite amapanga mphamvu ya maginito ndipo amatha kukopa zinthu zina zamaginito.

Kukakamiza: Maginito a Hematite ali ndi mphamvu yochepa ya Coercivity, kutanthauza kuti, amafunika mphamvu yaying'ono yakunja ya maginito kuti aigwiritse ntchito. Izi zimapangitsa maginito a Hematite kukhala osinthasintha komanso osavuta kugwiritsa ntchito m'mapulogalamu ena.

Kukana dzimbiri: Maginito a Hematite ndi okhazikika bwino m'malo ouma, koma amatha kuwononga m'malo onyowa kapena onyowa. Chifukwa chake, nthawi zina, maginito a Hematite amafunika kukonzedwa pamwamba kapena kupakidwa utoto kuti awonjezere kukana kwawo dzimbiri.

B. Kugwiritsa ntchito maginito a Hematite

Zipangizo zamaginito zachikhalidwe: Maginito a Hematite nthawi zambiri amagwiritsidwa ntchito popanga zinthu zamaginito zachikhalidwe, monga maginito a firiji, zomata zamaginito, ndi zina zotero. Chifukwa cha maginito ake ocheperako komanso mphamvu zochepa, maginito a Hematite ndi osavuta kuwamata pamwamba pa chitsulo kapena zinthu zina zamaginito, ndipo angagwiritsidwe ntchito pokonza zinthu, zinthu za minofu ndi ntchito zina.

Zipangizo zosungira deta:Maginito a Hematite alinso ndi ntchito zina mu zida zosungira deta. Mwachitsanzo, mu ma hard disk drive, maginito a Hematite amagwiritsidwa ntchito popanga zigawo zamaginito pamwamba pa disk kuti asungire deta.

Zipangizo zojambulira zithunzi zachipatala: Maginito a Hematite amagwiritsidwanso ntchito kwambiri muzipangizo zojambulira zamankhwala, monga makina ojambulira maginito (MRI). Maginito a Hematite angagwiritsidwe ntchito ngati jenereta ya maginito mu dongosolo la MRI kuti apange ndikuwongolera mphamvu ya maginito, motero kuzindikira kujambula kwa minofu ya anthu.

Mapeto: Maginito a Hematite ali ndi mphamvu ya maginito yocheperako, mphamvu yochepa ya maginito komanso mphamvu zina zotsutsana ndi dzimbiri. Amagwiritsidwa ntchito kwambiri popanga zinthu zamaginito zachikhalidwe, zida zosungira deta, komanso kujambula zithunzi zachipatala. Komabe, chifukwa cha kuchepa kwa mphamvu ya maginito ndi magwiridwe antchito ake, maginito a Hematite sali oyenera kugwiritsa ntchito zina zomwe zimafuna mphamvu ya maginito yochulukirapo komanso magwiridwe antchito.

Pali kusiyana koonekeratu pakati pa maginito a Neodymium ndi maginito a Hematite m'mapangidwe a mankhwala, mphamvu zamaginito, ndi malo ogwiritsira ntchito.Maginito a Neodymium amapangidwa ndi neodymium ndi chitsulo, okhala ndi maginito amphamvu komanso Coercivity yapamwamba. Amagwiritsidwa ntchito kwambiri m'magawo monga zida zamaginito zoyendetsera maginito, maginito, maginito olumikizira maginito, ndi ma mota othamanga kwambiri. Chifukwa maginito a Neodymium amatha kupanga maginito amphamvu, amatha kusintha mphamvu zamagetsi ndi mphamvu, kupereka mphamvu zamaginito zothandiza, ndikuwonjezera mphamvu ndi magwiridwe antchito a injini.Maginito a Hematite amapangidwa makamaka ndi miyala yachitsulo, ndipo gawo lalikulu ndi Fe3O4. Ali ndi mphamvu yamagetsi yapakati komanso mphamvu yochepa. Maginito a Hematite amagwiritsidwa ntchito kwambiri popanga zinthu zamaginito zachikhalidwe komanso zida zina zojambulira zamankhwala. Komabe, kukana dzimbiri kwa maginito a Hematite ndi kofooka, ndipo kuchiza kapena kuphimba pamwamba pa nthaka kumafunika kuti kuwonjezere kukana dzimbiri.

Mwachidule, pali kusiyana pakati pa maginito a Neodymium ndi maginito a Hematite mu kapangidwe ka mankhwala, mphamvu zamaginito ndi malo ogwiritsira ntchito. Maginito a Neodymium amagwiritsidwa ntchito m'magawo omwe amafuna mphamvu yamaginito yamphamvu komanso mphamvu yayikulu, pomwe maginito a Hematite amagwiritsidwa ntchito popanga zinthu zamaginito zachikhalidwe komanso zida zina zojambulira zamankhwala. Ngati mukufuna kugulamaginito a chikho cha neodymium opangidwa ndi countersunk, chonde titumizireni uthenga mwamsanga. Fakitale yathu ili ndi zambirimaginito a neodymium opangidwa ndi countersunk akugulitsidwa.
