Kodi pali kusiyana kotani pakati pa maginito a ceramic ndi neodymium?

Mawu Oyamba

M'makampani amakono, maginito ndi chinthu chofunikira kwambiri.Mwa iwo, maginito a ceramic ndi maginito a neodymium ndi zida ziwiri zomwe zimagwiritsidwa ntchito ndi maginito.Nkhaniyi ikufuna kufananiza ndi kusiyanitsa mawonekedwe ndi ntchito za maginito a ceramic ndi maginito a neodymium.Choyamba, tikuwonetsa mawonekedwe, njira zokonzekera, ndikugwiritsa ntchito maginito a ceramic m'minda monga zida zamagetsi ndi zida zamawu.Kenako, tikambirana za maginito a neodymium, njira zokonzekera, ndikugwiritsa ntchito kwawo m'mafakitale monga zida zatsopano zamagetsi ndi zida zamankhwala.Pomaliza, tifotokozera mwachidule kusiyana ndi ubwino wa maginito a ceramic ndi maginito a neodymium, kutsindika kufunika kwawo m'madera osiyanasiyana.Kupyolera mu kufotokozera kwa nkhaniyi, timvetsetsa bwino ndikugwiritsa ntchito mitundu iwiri ya maginito.

A. Kufunika kwa maginito a neodymium m'makampani amakono: Maginito a Neodymium ndi maginito amphamvu omwe ali ndi ntchito zosiyanasiyana, monga zipangizo zamagetsi, makampani oyendetsa galimoto, zipangizo zamankhwala, ndi zina zotero.

B. Yambitsani mutu wa nkhaniyi: Kusiyana Pakati pa Maginito a Ceramic ndi Maginito a Neodymium: Yambitsani mitu yomwe idzakambidwe, yomwe ndi kusiyana ndi kusiyanitsa pakati pa maginito a Ceramic ndi Neodymium Magnets.

1.1 Makhalidwe ndi kugwiritsa ntchito maginito a ceramic

A. Kukonzekera ndi kupanga maginito a neodymium mu mawonekedwe osiyanasiyana:Silinda, Countersunkndimphete za Neodymium MagnetsMaginito a Neodymium nthawi zambiri amapangidwa kuchokera kuzinthu zachitsulo monga lanthanide neodymium ndi chitsulo.

B. Maginito a maginito a neodymium ndi malo ogwiritsira ntchito

1. Mphamvu ya maginito ndi mphamvu yokakamiza ya maginito a neodymium: Maginito a Neodymium panopa ndi amodzi mwa maginito amphamvu kwambiri, omwe ali ndi mphamvu ya maginito yokwera kwambiri komanso mphamvu yokakamiza.

2. Kugwiritsa ntchito maginito a neodymium pazida zatsopano za mphamvu: Chifukwa cha mphamvu yake yamphamvu ya maginito, maginito a neodymium amagwiritsidwa ntchito kwambiri pazida zamphamvu zatsopano monga majenereta, makina oyendera mphepo, ndi magalimoto amagetsi.

3. Kugwiritsa ntchito maginito a neodymium pazida zamankhwala: Maginito a Neodymium alinso ndi ntchito zofunika kwambiri pazachipatala, monga maginito mu zida za MRI.(Dinani apa kuti mupeze malangizo a maginito)

2.1 Kusiyana pakati pa maginito a ceramic ndi maginito a neodymium

A. Kusiyana kwa kapangidwe kazinthu

1. Kupanga kwakukulu kwa maginito a ceramic: Maginito a ceramic nthawi zambiri amakhala ndi ferrite, chitsulo cha barium silicate ndi zinthu zina zadothi.

2. Zigawo zazikulu za maginito a neodymium: Maginito a Neodymium amapangidwa makamaka ndi zinthu zachitsulo monga neodymium ndi chitsulo.

B. Kusiyana kwa maginito

1. Kuyerekeza mphamvu ya maginito ndi mphamvu yokakamiza ya maginito a ceramic: Poyerekeza ndi maginito a neodymium, maginito a ceramic ali ndi mphamvu yochepa ya maginito, koma amatha kukhalabe ndi maginito okhazikika pansi pa kutentha kwakukulu ndi malo ovuta.

2. Kufananiza mphamvu ya maginito ndi mphamvu yokakamiza ya maginito a neodymium: Maginito a Neodymium ali ndi mphamvu ya maginito kwambiri komanso mphamvu yokakamiza, ndipo panopa ndi imodzi mwa zipangizo zamphamvu kwambiri za maginito.

C. Kusiyana m'magawo ofunsira

1. Minda yayikulu yogwiritsira ntchito maginito a ceramic: Maginito a ceramic amagwiritsidwa ntchito kwambiri pazida zamagetsi ndi zida zamawu ndi madera ena.

2. Minda yayikulu yogwiritsira ntchito maginito a neodymium: Maginito a Neodymium amagwiritsidwa ntchito kwambiri pazida zatsopano zamagetsi ndi zida zamankhwala ndi magawo ena.

In mapeto

1.Maginito a Ceramic, omwe amadziwikanso kuti maginito olimba a ferrite, amapangidwa ndi barium kapena strontium ndipo adapangidwa koyambirira kwa zaka za m'ma 1960 ngati m'malo mwa maginito achitsulo okwera mtengo kwambiri.Maginitowa ndi olimba kwambiri, osasunthika, komanso amakhala ndi mphamvu zochepa poyerekeza ndi maginito ena.Komabe, maginito a ceramic ferrite amagwiritsidwa ntchito kwambiri chifukwa cha kukana kwawo kwa demagnetization, kukana kwa dzimbiri komanso mwayi wapamwamba wamtengo.

Maginito a Ceramic amasunga 45% ya kutentha kwa chipinda chawo ndi maginito pa kutentha mpaka madigiri 350 Fahrenheit.Kuwonongekaku kumakhala kofanana ndi kutentha kowonjezereka ndipo kusintha kwa maginito kumasinthika mpaka pafupifupi 840 ° F, pomwe maginito a ceramic amakhala opanda mphamvu.Maginito a Ceramic omwe amatha kutentha mpaka 1800 ° F amatha kupangidwanso kuti agwiritse ntchito.Komabe, pamwamba pa madigiri 1800 Fahrenheit, zosinthazo sizingasinthe.

3. Maginito a NdFeB, omwe amadziwikanso kuti maginito a neodymium kapena maginito a NdFeB, ndi maginito a tetragonal opangidwa ndi neodymium, iron, ndi boron.Malinga ndi njira zosiyanasiyana kupanga, NdFeB okhazikika maginito zipangizo akhoza kugawidwa mu sintered NdFeB, womangidwa NdFeB, otentha mbamuidwa NdFeB, etc. NdFeB okhazikika maginito zipangizo ndi makhalidwe a mtengo ntchito mtengo, ang'onoang'ono, zabwino dzimbiri kukana, ndi ntchito khola.M'zaka zaposachedwa, akhala akugwiritsidwa ntchito kwambiri m'magalimoto amagetsi atsopano, zamagetsi ogula, nyukiliya maginito resonance imaging, mphamvu yamphepo, zakuthambo ndi zina.NdFeB okhazikika maginito zakuthupi ndi m'badwo wachitatu osowa dziko okhazikika maginito zakuthupi ndi chitukuko yachangu, ntchito widest, ntchito apamwamba mtengo ndi ntchito yabwino mabuku.

4.NdFeB maginito ndi amphamvu maginito zakuthupi ndi mankhwala mkulu maginito mphamvu, mkulu coercive mphamvu, bata mkulu ndi zina zotero.Chifukwa chake, ili ndi magawo osiyanasiyana ogwiritsira ntchito m'makampani amakono.

Choyamba, maginito a NdFeB amagwiritsidwa ntchito kwambiri pazida zosiyanasiyana zamagetsi monga ma mota, ma jenereta ndi masensa.Mwachitsanzo, itha kugwiritsidwa ntchito mu injini zamagalimoto amagetsi, chifukwa maginito a NdFeB amatha kupereka mphamvu yamaginito, potero kumapangitsa kuti magalimoto amagetsi aziyenda bwino.

Kachiwiri, maginito a NdFeB amagwiritsidwanso ntchito kwambiri pazinthu zamagetsi zamagetsi monga ma hard drive apakompyuta, osewera a DVD ndi ma stereo.Ma diski amafunikira mitu kuti awerenge zambiri, ndipo mitu imafunikira zida zamaginito kuti zitheke, chifukwa chake maginito a NdFeB atha kugwiritsidwa ntchito pama drive a disk.Komanso, NdFeB maginito Angagwiritsidwenso ntchito okamba zomvetsera, amene akhoza kuonjezera linanena bungwe mphamvu ndi khalidwe la okamba.

Kuphatikiza apo, maginito a NdFeB angagwiritsidwenso ntchito pazida zamankhwala ndi zida zolekanitsa maginito ndi magawo ena.Mwachitsanzo, zachipatala, zitha kugwiritsidwa ntchito pazida zamaginito zamaginito (MRI), chifukwa maginito a neodymium iron boron amatha kupereka mphamvu ya maginito yokwanira kusanthula minyewa ndi ziwalo mkati mwa thupi la munthu.M'munda wa zida maginito kulekana, NdFeB maginito angagwiritsidwe ntchito olekanitsa maginito kuthandiza kulekanitsa zinthu zosiyanasiyana.

Mwachidule, maginito a NdFeB akhala chimodzi mwazinthu zofunika kwambiri pamakampani amakono chifukwa chazinthu zawo zabwino kwambiri zamaginito.Amagwiritsidwa ntchito kwambiri pazida zamagetsi, zamagetsi ogula, zida zamankhwala, ndi zida zolekanitsa maginito, zomwe zimatithandizira kwambiri pamoyo wathu ndi ntchito.
