ʻO ka magnet Neodymium a me ka magnet Hematite ʻelua mau mea magnetic maʻamau, i hoʻohana nui ʻia ma kā lākou mau kahua. No ka magnet Neodymium ka magnet Rare-earth, i haku ʻia me ka neodymium, ka hao, ka boron a me nā mea ʻē aʻe. Loaʻa iā ia ka magnetism ikaika, ke Coercivity kiʻekiʻe a me ke kūpaʻa ʻana i ka corrosion, a hoʻohana nui ʻia i loko o ka motika, ka mīkini hana, nā lako acoustic a me nā kahua ʻē aʻe. ʻO ka magnet Hematite kahi ʻano mea magnetic ʻano ore, i hana nui ʻia me ka hematite i loaʻa ka hao ore. Loaʻa iā ia nā waiwai magnetic a me nā waiwai anti-corrosion, a hoʻohana nui ʻia i nā mea magnetic kuʻuna, nā lako mālama ʻikepili a me nā kahua ʻē aʻe.Ma kēia ʻatikala, e kūkākūkā hohonu ʻia nā ʻano a me nā noi o ka magnet Neodymium a me ka magnet Hematite, a e hoʻohālikelike ʻia ko lākou ʻokoʻa.

Ⅰ.Nā ʻano a me ka hoʻohana ʻana o ka magnet Neodymium:

A. Nā ʻano o ka magnet Neodymium:

Ka hoʻohuihui kemika:ʻO ka magnet Neodymium he neodymium (Nd), hao (Fe) a me nā mea ʻē aʻe. ʻO ka nui o ka neodymium ma waena o 24% a me 34%, ʻoiai ʻo ka nui o ka hao ka hapa nui. Ma waho aʻe o ka neodymium a me ka hao, hiki i ka magnet Neodymium ke loaʻa kekahi mau mea ʻē aʻe, e like me ka boron (B) a me nā mea honua kakaikahi ʻē aʻe, e hoʻomaikaʻi i kona mau waiwai magnetic.

Mākēneki:ʻO ka magnet Neodymium kekahi o nā magnet maʻamau kālepa ikaika loa i ʻike ʻia i kēia manawa. Loaʻa iā ia ka magnetization kiʻekiʻe loa, hiki ke piʻi i kahi pae i hiki ʻole i nā magnet ʻē aʻe ke hoʻokō. Hāʻawi kēia iā ia i nā waiwai magnetic maikaʻi loa a kūpono loa no nā noi e pono ai ka magnetization kiʻekiʻe.

Ka hoʻoikaika ʻana:He kiʻekiʻe ka Coercivity o ka magnet Neodymium, ʻo ia hoʻi he ikaika kona pale ʻana i ke kahua magnetic a me ke kūʻē ʻana i ka shear. I ka hoʻohana ʻana, hiki i ka magnet Neodymium ke mālama i kona kūlana magnetization a ʻaʻole maʻalahi ka hoʻopilikia ʻia e ke kahua magnetic o waho.

Ke kū'ē'ē i ka palaho:ʻOi aku ka maikaʻi ʻole o ke kūpaʻa ʻana o ka magnet Neodymium i ka palaho, no laila pono ka mālama ʻana i ka ʻili, e like me ka electroplating a i ʻole ka mālama wela, e hoʻomaikaʻi i kona kūpaʻa ʻana i ka palaho. Hiki i kēia ke hōʻoia i ka hiki ʻole o ka magnet Neodymium ke palaho a me ka oxidation i ka hoʻohana ʻana.

B. Hoʻohana ʻia o ka magnet Neodymium:

Motika a me ka mīkini hana: Hoʻohana nui ʻia ka magnet Neodymium i loko o ke kaʻa a me ka mīkini hana ma muli o kona magnetization kiʻekiʻe a me ka Coercivity. Hiki i ka magnet Neodymium ke hāʻawi i kahi kahua magnetic ikaika, i ʻoi aku ka maikaʻi o ka pono a me ka hana o nā kaʻa a me nā mīkini hana.

Nā lako leo: Hoʻohana ʻia ka magnet Neodymium i nā lako leo, e like me nā mea hoʻolele leo a me nā headphone. Hiki i kona kahua magnetic ikaika ke hoʻopuka i ka leo kiʻekiʻe aʻe a me nā hopena leo maikaʻi aʻe. Nā lako lapaʻau: Hoʻohana nui ʻia ka magnet Neodymium i nā lako lapaʻau. No ka laʻana, i nā lako kiʻi resonance magnetic (MRI), hiki i ka magnet Neodymium ke hoʻopuka i kahi kahua magnetic paʻa a hāʻawi i nā kiʻi kiʻekiʻe.

ʻOihana mokulele: I ka ʻoihana aerospace, hoʻohana ʻia ka magnet Neodymium e hana i ka ʻōnaehana hoʻokele a me ka hoʻokele o nā mokulele, e like me ka gyroscope a me nā mea hoʻokele. ʻO kona magnetization kiʻekiʻe a me ke kūpaʻa ʻana i ka corrosion e lilo ia i koho kūpono.

I ka hopena, ma muli o kona ʻano kemika kūikawā a me nā ʻano maikaʻi loa,Nā mākēneki honua laha ʻole neodymiumhe kuleana koʻikoʻi ia ma nā ʻano noi like ʻole, ʻoi aku hoʻi i nā mīkini uila, nā lako leo, nā lako lapaʻau a me ka ʻoihana aerospace. He mea nui hoʻi e hōʻoia i ka hana a me ke ola oNā magnet ʻano kūikawā Neodymium, e kāohi i kona loli o ka mahana a hana i nā hana kūpono e kū'ē i ka palaho.

Ⅱ.ʻAno a me ka hoʻohana ʻana o ka magnet Hematite:

A. ʻAno o ka makeneka Hematite:

Ka hoʻohuihui kemika:ʻO ka makeneka hematite ka mea nui i hana ʻia me ka hao hao, aia i loko ka ʻokeka hao a me nā mea haumia ʻē aʻe. ʻO kona ʻano kemika nui ʻo Fe3O4, ʻo ia hoʻi ka ʻokeka hao.

Mākēneki: He magnet kūpono ko ka hematite magnet a no ka mea magnetic nāwaliwali. Ke loaʻa kahi kahua magnetic waho, e hana nā magnet Hematite i ka magnetism a hiki ke huki i kekahi mau mea magnetic.

Ka hoʻoikaika ʻana: He haʻahaʻa loa ka Coercivity o ka makeneka hematite, ʻo ia hoʻi, pono ia i kahi kahua makeneka waho liʻiliʻi e magnetize iā ia. ʻO kēia ka mea e maʻalahi ai nā makeneka hematite e hana ma kekahi mau noi.

Ke kū'ē'ē i ka palaho: He paʻa loa ka makeneka hematite i kahi maloʻo, akā hiki ke pala i kahi pulu a pulu paha. No laila, i kekahi mau noi, pono nā makeneka hematite i ka mālama ʻili a i ʻole ka uhi ʻana e hoʻoikaika i ko lākou kūpaʻa i ka pala.

B. Ka hoʻohana ʻana o nā mākēneki Hematite

Nā mea makeneka kuʻuna: Hoʻohana pinepine ʻia nā makeneka hematite e hana i nā mea makeneka kuʻuna, e like me nā makeneka pahu hau, nā pepili makeneka, a pēlā aku. Ma muli o kona magnetism kaulike a me ka Coercivity haʻahaʻa, maʻalahi ke hoʻopili ʻia nā makeneka hematite ma luna o ka metala a i ʻole nā ​​​​mea makeneka ʻē aʻe, a hiki ke hoʻohana ʻia no ka hoʻopaʻa ʻana i nā mea, nā mea ʻiʻo a me nā noi ʻē aʻe.

Nā lako mālama ʻikepili:Loaʻa i ka makeneka hematite kekahi mau hana i nā lako mālama ʻikepili. No ka laʻana, i loko o nā mīkini paʻakikī, hoʻohana ʻia nā makeneka hematite e hana i nā papa makeneka ma ka ʻili o ka disk no ka mālama ʻana i ka ʻikepili.

Nā lako hana kiʻi lapaʻau: Hoʻohana nui ʻia nā magnet hematite i nā lako hana kiʻi lapaʻau, e like me nā ʻōnaehana magnetic resonance imaging (MRI). Hiki ke hoʻohana ʻia ka magnet hematite ma ke ʻano he mea hana kahua magnetic i ka ʻōnaehana MRI e hana a kāohi i ke kahua magnetic, no laila e hoʻokō ana i ke kiʻi ʻana o nā ʻiʻo kanaka.

Hopena: He magneto kūpono ko ka hematite, he haʻahaʻa ka Coercivity a me kekahi kūpaʻa i ka palaho. Loaʻa iā ia nā noi ākea i ka hana ʻana i nā mea magnetic kuʻuna, nā mea mālama ʻikepili, a me nā kiʻi lapaʻau. Eia nō naʻe, ma muli o ka palena o kona magnetism a me ka hana, ʻaʻole kūpono nā magneto Hematite no kekahi mau noi e koi ana i ka magnetism kiʻekiʻe a me nā koi hana.

Aia kekahi mau ʻokoʻa maopopo ma waena o ka magnet Neodymium a me ka magnet Hematite i ka hoʻohui kemika, nā waiwai magnetic a me nā kahua noi.Hana ʻia ka magnet Neodymium me ka neodymium a me ka hao, me ka magnetism ikaika a me ka Coercivity kiʻekiʻe. Hoʻohana nui ʻia ia ma nā kahua e like me nā mea hoʻokele magnetic, nā magnet, nā buckles magnetic, a me nā motika hana kiʻekiʻe. Ma muli o ka hiki i ka magnet Neodymium ke hana i kahi kahua magnetic ikaika, hiki iā ia ke hoʻololi i ka ikehu uila a me ka mana, hāʻawi i ke kahua magnetic kūpono, a hoʻomaikaʻi i ka mana a me ka pono o ka motika.ʻO ka mea nui o ka makeneka hematite he hao hao, a ʻo ka mea nui ʻo Fe3O4. He magnetism waena kona a he haʻahaʻa ka Coercivity. Hoʻohana nui ʻia nā makeneka hematite i ka hana ʻana i nā mea magnetic kuʻuna a me kekahi mau lako hana kiʻi lapaʻau. Eia nō naʻe, ʻaʻole maikaʻi ke kūpaʻa ʻana o nā makeneka hematite i ka pala, a pono ka mālama ʻana i ka ʻili a i ʻole ka uhi ʻana e hoʻoikaika i ko lākou kūpaʻa ʻana i ka pala.

I ka hōʻuluʻulu ʻana, aia nā ʻokoʻa ma waena o ka magnet Neodymium a me ka magnet Hematite i ka haku mele kemika, nā waiwai magnetic a me nā kahua noi. Pili ka magnet Neodymium i nā kahua e koi ana i ke kahua magnetic ikaika a me ka Coercivity kiʻekiʻe, ʻoiai pili ka magnet Hematite i ka hana ʻana i nā mea magnetic kuʻuna a me kekahi mau lako hana kiʻi lapaʻau. Inā pono ʻoe e kūʻainā mākēneki kīʻaha neodymium i hoʻokuʻu ʻia, e ʻoluʻolu e leka uila iā mākou ASAP. He nui kā mākou hale hananā mākēneki neodymium countersunk no ke kūʻai aku.
