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

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

A. Nā ʻano o ka neodymium magnet:

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

Mākēneki:ʻO ka neodymium magnet kekahi o nā mea hoʻokele maʻamau kālepa ikaika loa i ʻike ʻia i kēia manawa.Loaʻa iā ia ka magnetization kiʻekiʻe loa, hiki ke piʻi i kahi kiʻekiʻe i hiki ʻole i nā mea magneti ʻē aʻe ke hoʻokō.Hāʻawi kēia iā ia i nā waiwai magnetic maikaʻi loa a kūpono loa i nā noi e koi ana i ka magnetization kiʻekiʻe.

Ka hoʻokoe ʻana:Loaʻa i ka Coercivity kiʻekiʻe ka neodymium magnet, ʻo ia hoʻi he ikaika ikaika ka pale ʻana a me ke kūpaʻa shear.I ka noi, hiki i ka neodymium magnet ke mālama i kona kūlana magnetization a ʻaʻole maʻalahi e hoʻopili ʻia e ka pā magnetic waho.

ʻO ke kūpaʻa ʻino:ʻAʻole maikaʻi ka pale ʻana o ka neodymium magnet, no laila, ʻoi aku ka maikaʻi o ka mālama ʻana i ka ʻili, e like me ka electroplating a i ʻole ka wela wela, e hoʻomaikaʻi i kona kūpaʻa corrosion.Hiki i kēia ke hōʻoia i ka neodymium magnet ʻaʻole maʻalahi i ka corrosion a me ka oxidation i ka hoʻohana ʻana.

B.Application o Neodymium magnet:

Motor a me ka mīkini hana hana: Hoʻohana nui ʻia ka neodymium magnet i ka kaʻa a me ka mea hana ma muli o kāna magnetization kiʻekiʻe a me Coercivity.Hiki i ka neodymium magnet ke hāʻawi i kahi māla magnetic ikaika, i ʻoi aku ka maikaʻi o nā kaʻa a me nā mea hana.

Mea hoʻokani leo: Hoʻohana pū ʻia ka neodymium magnet i nā mea kani, e like me nā leo kani a me nā headphone.Hiki i kona mānoanoa ikaika ke hoʻopuka i ka hoʻopuka kani kiʻekiʻe a me nā hopena maikaʻi maikaʻi.No ka laʻana, i loko o nā mea hana kiʻi magnetic resonance imaging (MRI), hiki i ka Neodymium magnet ke hana i kahi māla paʻa paʻa a hāʻawi i nā kiʻi kiʻekiʻe.

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

I ka hopena, ma muli o kāna ʻano kemika kūikawā a me nā hiʻohiʻona maikaʻi loa,ʻO ka neodymium nā mea hoʻokalakupua honuaHe hana koʻikoʻi ia i nā ʻano noiʻi like ʻole, ʻoi aku ka nui o nā mīkini uila, nā lako acoustic, nā mea lapaʻau a me nā ʻoihana aerospace.He mea nui nō hoʻi e hōʻoia i ka hana a me ke ola o Neodymium magnet, kaohi i kona hoʻololi ʻana i ka mahana a lawe i nā ana anti-corrosion kūpono.

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

A. Ke ano o ka Hematite magnet:

KemimiʻO ka Hematite magnet ka mea nui i ka hao hao, kahi iron oxide a me nā mea haumia ʻē aʻe.ʻO Fe3O4 kona hui kemika nui, ʻo ia ka hao oxide.

Mākēneki: Loaʻa i ka Hematite magnetism haʻahaʻa haʻahaʻa a no nā mea magnetic palupalu.I ka wā e loaʻa ai kahi mākēneki waho, e hoʻohua nā mea hoʻokalakupua Hematite i ka magnetism a hiki ke huki i kekahi mau mea magnetic.

Ka hoʻokoe ʻana: He haʻahaʻa haʻahaʻa ka Coercivity ʻo Hematite magnet, ʻo ia hoʻi, pono ia i kahi māla liʻiliʻi o waho e hoʻokalakupua iā ia.Hoʻololi kēia i nā magnetite Hematite a maʻalahi hoʻi e hana i kekahi mau noi.

ʻO ke kūpaʻa ʻino: He paʻa ka Hematite magnet ma kahi maloʻo, akā maʻalahi ia i ka corrosion ma ka ʻāina pulu a haʻahaʻa paha.No laila, i kekahi mau noi, pono nā mea magnet Hematite i ka mālama ʻana a i ʻole ka uhi ʻana e hoʻomaikaʻi i ko lākou kūpaʻa ʻana.

B. Hoʻohana ʻana i nā mea magnet Hematite

Nā mea magnetic kuʻuna: Hoʻohana pinepine ʻia nā mea magnet Hematite no ka hana ʻana i nā mea magnetic maʻamau, e like me nā mea hoʻoheheʻe pahu, nā mea hoʻopili magnetic, a me nā mea ʻē aʻe. hoʻohana ʻia no ka hoʻoponopono ʻana i nā mea, nā mea kiko a me nā noi ʻē aʻe.

Lako mālama ʻikepili:Loaʻa iā Hematite magnet kekahi mau noi i nā lako mālama ʻikepili.No ka laʻana, i loko o nā disk drive paʻakikī, hoʻohana ʻia nā mea magnet Hematite e hana i nā papa magnetic ma ka ʻili disk no ka mālama ʻana i ka ʻikepili.

Lapaʻau kiʻi lāʻau: Hoʻohana nui ʻia nā mea magnet Hematite i nā mea hana kiʻi olakino, e like me nā ʻōnaehana magnetic resonance imaging (MRI).Hiki ke hoʻohana ʻia ka Hematite magnet e like me ka mea hoʻoheheʻe magnetic i loko o ka ʻōnaehana MRI e hana a hoʻomalu i ka māla magnetic, no laila e ʻike ai i ke kiʻi ʻana o nā ʻiʻo kanaka.

Ka hopena: Loaʻa iā Hematite magnetism haʻahaʻa haʻahaʻa, Coercivity haʻahaʻa a me kekahi kūpaʻa corrosion.Loaʻa iā ia nā noi ākea i ka hana ʻana i nā mea magnetic kuʻuna, nā mea mālama ʻikepili, a me nā kiʻi lāʻau lapaʻau.Eia nō naʻe, ma muli o ka palena o kāna magnetism a me kāna hana, ʻaʻole kūpono nā magnetite Hematite no kekahi mau noi e koi ana i ka magnetism kiʻekiʻe a me nā koi hana.

Aia nā ʻokoʻa ʻokoʻa ma waena o Neodymium magnet a me Hematite magnet i ka haku melemele, nā waiwai magnetic a me nā kahua noi.Hoʻokumu ʻia ka neodymium magnet me ka neodymium a me ka hao, me ka magnetism ikaika a me ka Coercivity kiʻekiʻe.Hoʻohana nui ʻia ia i nā kula e like me nā mea hoʻokele magnetic, nā mea magnet, nā kīʻaha magnetic, a me nā mīkini hana kiʻekiʻe.No ka mea hiki i ka Neodymium magnet ke hana i kahi māla ikaika, hiki iā ia ke hoʻololi i ka ikehu uila a me ka mana, hāʻawi i ka māla magnetic kūpono, a hoʻomaikaʻi i ka mana a me ka pono o ka kaʻa.ʻO ka Hematite magnet ka mea nui i ka hao hao, a ʻo ka mea nui ʻo Fe3O4.Loaʻa iā ia ka magnetism haʻahaʻa a me ka Coercivity haʻahaʻa.Hoʻohana nui ʻia nā magnetite hematite i ka hana ʻana i nā mea magnetic kuʻuna a me kekahi mau mea hana kiʻi olakino.Eia nō naʻe, ʻilihune ka pale ʻana o nā mea magnet Hematite, a pono ka mālama ʻana a i ʻole ka uhi ʻana i mea e hoʻomaikaʻi ai i ko lākou kūpaʻa ʻana.

I ka hōʻuluʻulu ʻana, aia nā ʻokoʻa ma waena o Neodymium magnet a me Hematite magnet i ka haku mele, nā waiwai magnetic a me nā kahua noi.Hoʻohana ʻia ka magnet Neodymium i nā māla e koi ana i ka māla magnetic ikaika a me ka Coercivity kiʻekiʻe, ʻoiai ʻo Hematite magnet e pili ana i ka hana kuʻuna mea magnetic a me kekahi mau mea hana kiʻi lāʻau lapaʻau. Inā pono ʻoe e kūʻai.nā kīʻaha neodymium countersunk, eʻoluʻolu e leka uila iā mākou ASAP.ʻO kā mākou hale hana he nuikūʻai aku i nā magnet neodymium countersunk.
