Pehea e hoʻolei aku ai i nā magnet neodymium?

Ma kēia ʻatikala, e kūkākūkā mākou i ka hoʻomākaukau, ka hana ʻana a me ka hoʻohana ʻana i nā magnet neodymium. Ma ke ʻano he mea me ka waiwai noi nui,neodymium magnetshoʻohana nui ʻia i nā mea uila, nā kaʻa, nā sensor magnetic a me nā māla ʻē aʻe. Ua hoʻokipa nui ʻia nā mea magnet Neodymium no kā lākou mau waiwai magnetic maikaʻi loa, ka paʻa wela maikaʻi a me ke kūpaʻa corrosion. Ma kēia ʻatikala, e hōʻike mua mākou i kahi ʻike kumu o nā magnet neodymium, me kā lākou mau hiʻohiʻona a me kā lākou hana. A laila, e kūkākūkā hohonu mākou i ke kaʻina hana hoʻomākaukau o nā magnet neodymium, me ka hoʻomākaukau ʻana i nā mea maka, ke ʻano o ka pauka metallurgy a me ke ʻano metala plating, etc. a me ka palekana. ʻO ka mea hope loa, e hoʻolauna mākou i ka hoʻohana ʻana a me ka mālama ʻana i nā magnet neodymium, a nānā i mua i kā lākou hoʻomohala e hiki mai ana. Ma o ke aʻo ʻana i kēia ʻatikala, manaʻolana wau e hāʻawi i ka poʻe heluhelu i ke alakaʻi no ka ʻike hohonu o ka ʻike kumu a me nā noi pili o nā magnet neodymium.

1.1 Nā noi a me ke koʻikoʻi o nā Magnet Neodymium

I kēia mau lā, ulu wikiwiki a hoʻohana nui ʻia nā magnet neodymium. Hiki ke hoʻololi i nā mea hao maʻemaʻe maʻemaʻe, alnico a me samarium cobalt magnets i nā kula he nui e like me nā kaʻa uila, nā mea kani a me nā mika, ka ʻoihana kaʻa, ka ʻoihana petrochemical a me nā huahana mālama olakino magnetic. Hiki ke hana i nā ʻano like ʻole: e like me nā magnet disc, ring magnets, rectangular magnets, arc magnets a me nā ʻano like ʻole o ka magnet.

Loaʻa nā magnet Neodymium i nā huahana uila o kēlā me kēia lā, e like me ka paʻa paʻa, kelepona paʻalima, nā pepeiao pepeiao, a me nā mea ʻē aʻe. Ma muli o ka liʻiliʻi liʻiliʻi a me ke kaumaha māmā o ka neodymium magnet, nui ka flux magnetic. No laila, kūpono loa ia no ka hoʻoikaika ʻana i ke kani o nā pae hana ʻoihana a me nā kahua pāʻani nui. Ma waena o kāna mau leo ​​leo ʻoihana he nui, ua hoʻomohala ʻo TM brand professional audio i nā ʻano ʻāpana neodymium magnetic kiʻekiʻe ma o ka nui o nā hoʻokolohua, a hoʻonui i ka laina laina laina kuʻuna e hoʻomohala i ka LA-102F, nona ka mana kiʻekiʻe a me ka hoʻolālā paʻa. . , Māmā māmā neodymium magnetic unit line array performance speaker.

Ua lilo ʻo Magnets i mea waiwai nui i kēia ao. Hele mai nā mākēneki i nā ʻano like ʻole, ka nui a me nā pae ikaika. Hiki i kēia ke huikau i ka wā e hoʻoholo ai i ka ikaika o nā magnet āu e pono ai no kāu papahana. Ma waena o nā mea magnet i ka honua i kēia lā, ua nui ka nānā ʻana i nā magnet neodymium, a ʻoi aku ka nui o ka poʻe i ʻike i ke koʻikoʻi o nā magnet neodymium ma muli o kāna mau hiʻohiʻona maikaʻi loa.

ʻO ka Neodymium ka mea maʻamau he metala honua laha ʻole e hana ma ke ʻano he magnet ikaika. Manaʻo ʻia lākou ʻo ka mea ikaika loa e pili ana i ko lākou ʻano. Hiki i ka neodymium magnet liʻiliʻi loa ke kākoʻo i hoʻokahi kaukani manawa i kona nui ponoʻī. ʻO ka Neodymium ka uku kūpono no nā magnet ikaika. Ua hoʻonui kēia mau kumu i ka kaulana o kēia magnet, i hoʻohana nui ʻia i ka honua hou.

ʻO Kina ka mea kūʻai nui loa o NdFeB ma ka honua i kēia manawa. Hoʻokō lākou ma kahi o 80% o nā pono o ka honua. Mai kona loaʻa ʻana i ka makahiki 1970, ua ulu nui kona koi. Ua ʻike ʻia lākou he mau magnet NIB, ma ka papa magnetic, aia ko lākou māka ma waena o N35 a i N54. Hoʻoponopono ʻia ka ikaika magnetic e ka mea hana e like me kā lākou pono ponoʻī.(Kaomi ma aneʻi no nā ʻōlelo aʻoaʻo helu magnet)

Hiki ke loaʻa nā neodymium magnet i nā ʻokoʻa wela a hiki ke nalowale i ka mahana ma nā wela kiʻekiʻe. Eia nō naʻe, hiki ke ʻike ʻia kekahi mau magnet neodymium kūikawā i ka honua o kēia manawa, hiki ke hoʻokō i kā lākou hana ma nā wela ambient kiʻekiʻe loa. ʻO ka haʻahaʻa haʻahaʻa o kēia mau magnet i hoʻohālikelike ʻia me nā mea magnet ʻē aʻe e mahalo i nā ʻoihana e hoʻohana ana iā lākou.

1.2 ʻIke kumu o nā neodymium magnet

A. ʻO ka neodymium magnet he mea laha ʻole ka honua i haku ʻia me ka neodymium, ka hao a me ka boron. Loaʻa iā ia ke ʻano kemika Nd2Fe14B a ʻo ia kekahi o nā mea magnetika ikaika loa i loaʻa i ke kālepa.

B. Loaʻa i nā neodymium nā hiʻohiʻona a me nā waiwai.

Nā waiwai mākēneki: Loaʻa i nā mea magnet Neodymium kiʻekiʻe loa ka huahana ikehu magnetic a me ka ikaika hoʻoikaika, e hiki ai iā lākou ke hoʻohua i nā māla magnetic ikaika loa. ʻO ia kekahi o nā mea magnet paʻa ikaika loa i kēia manawa i ka noi kālepa.

ʻO ke kūpaʻa wela: He kiʻekiʻe ka wela o ka hana ʻana o nā neodymium a hana maʻamau i ka pae Celsius. Eia naʻe, hoʻohaʻahaʻa mālie kona mau waiwai i ka wā i ʻoi aku ka mahana ma mua o kona wela hana kiʻekiʻe.

ʻO ke kūpaʻa ʻino: Ma muli o ka mea hao i loko o ka neodymium magnet, he mea ʻino ia i ka oxygen a me ka wai. No laila, koi pinepine ʻia ka uhi ʻana a i ʻole nā ​​​​lāʻau pale ʻē aʻe i nā noi kūpono.

2.1 Kaʻina hana hoʻomākaukau o ka neodymium magnet

A. Hoʻomākaukau ʻia nā mea maka: Ua hoʻomākaukau ʻia nā mea maka e like me ka neodymium, ka hao a me ka boron ma kekahi ʻāpana, a ua mālama ʻia ka mālama kino a me ke kemika.

1. Powder metallurgy: ʻO ia kekahi o nā ala nui no ka hoʻomākaukau ʻana i nā magnet neodymium.

2. Ka hoʻomākaukau ʻana i ka pauda: E hoʻohui i nā pauka maka ma kekahi ʻāpana, a e hoʻohua i nā pauka o nā ʻāpana i hoʻopaʻa ʻia ma o nā hopena kemika a i ʻole ke ʻano kino.

3. Alloying: E ​​hoʻokomo i ka pauka i loko o ka umu wela wela, a e hoʻokō i ka hoʻohuihui ʻana ma lalo o kekahi mau ʻano wela a me ka lewa e hana ai ia i mea hoʻohui me ka hui like. Ke kaomi ʻana: Hoʻokomo ʻia ka pauka alloy i loko o kahi ʻōpala a kaomi ʻia ma lalo o ke kaomi kiʻekiʻe e hana i kahi magnet me ke ʻano a me ka nui i makemake ʻia.

4. Sintering: e hoʻokomo i ka magnet i kaomi ʻia i loko o ka umu hoʻoheheʻe, a me ka sinter ma lalo o kekahi mau kūlana wela a me ka lewa e crystallize a loaʻa i nā waiwai magnetic i koi ʻia.

ʻO ke ala hoʻoheheʻe metala: ʻO ka ʻili o nā mea magnet neodymium maʻamau e hoʻopaʻa ʻia e hoʻonui i kona kūpaʻa corrosion a hoʻomaikaʻi i ka helehelena.

D. Nā hana hoʻomākaukau ʻē aʻe: Ma waho aʻe o ka pauka metala a me ka hoʻoheheʻe metala, nui nā ʻano hana ʻē aʻe no ka hoʻomākaukau ʻana i nā magnet neodymium, e like me ka hoʻoheheʻe ʻana i ka hopena, ka hoʻoheheʻe ʻana a pēlā aku.

2.3 Hoʻolālā ʻana a me ke ʻano o nā Mākēneki Neodymium

A. ʻenehana hoʻoponopono pololei: He kiʻekiʻe loa ka paʻakikī a me ka brittleness nā neodymium magnets, no laila e koi ʻia nā ʻenehana hoʻoponopono kikoʻī kūikawā i ke kaʻina hana, e like me ke ʻoki ʻana i ke kelepona, EDM, etc.

B. Ke noi a me ka hoʻolālā ʻana o nā Magnet Neodymium ma nā ʻano like ʻole:Poʻapuni, huinaha, a me Bar Neodymium Magnets: Hoʻohana maʻamau ʻia kēia mau ʻano o nā magnet Neodymium ma nā kahua o nā mea ʻike, nā kaʻa, a me nā mea lapaʻau.Mākēneki neodymium kūikawā: E like me nā pono noi kikoʻī a me nā koi hoʻolālā, hiki ke hoʻolālā a hana ʻia nā ʻano magnet neodymium kūikawā. Hoʻopili ʻia a hui pū ʻia o nā magnet neodymium: Hiki ke hoʻohui ʻia nā magnet Neodymium me nā mea ʻē aʻe, e like me ka hoʻopili ʻia ʻana ma nā cores hao, i hui pū ʻia me nā magnet ʻē aʻe, etc.h-Temperature Resistant Neodymium Magnets

3. Ka mālama ʻana a me ka pale ʻana i nā magnet neodymium

A. Ka uhi ʻana o ka ʻili: ʻO nā uhi maʻamau i hoʻohana ʻia me ka nickel plating, galvanizing, spray paint, etc.

B. Anti-rust a me ka anti-corrosion lapaʻau: ʻO ka ʻili o ka neodymium magnet pono e kū pono i ka anti-rust a me ka anti-corrosion lapaʻau e hoʻolōʻihi i kona ola lawelawe.

C. Encapsulation a me ka hoʻopili ʻana: Ma nā noi kūpono, pono e hoʻopili ʻia nā neodymium magnets i mea e pale ai i ka leakage magnetic a me ka mana o ke kaiapuni o waho.

4. Ka hoʻohana ʻana a me ka mālama ʻana i nā magnet neodymium

1. Nā hana a me nā kahua noi: Hoʻohana nui ʻia nā mea magnet Neodymium i nā uila, nā kaʻa, nā sensor magnetic, aerospace a me nā māla ʻē aʻe, e hāʻawi ana i nā waiwai magnetic maikaʻi loa no kēia mau ʻoihana.hoʻolikelike like ʻole me ke ʻano magnetiklawelawe.）
2. ʻO ka mālama ʻana no ka hoʻohana ʻana: I ka wā e hoʻohana ai i nā magnet neodymium, pono e hoʻolohe i kona brittleness a me nā hiʻohiʻona magnetic ikaika, a pale aku i nā mea e hōʻino ai, e like me ka collision, vibration a me ke kiʻekiʻe wela.
3. ʻO ka mālama ʻana a me ka mālama ʻana i ka wā lōʻihi: I ka wā e mālama ai i ka wā lōʻihi, pono e mālama ʻia nā magnet neodymium mai ka wai a me nā wahi haʻahaʻa kiʻekiʻe. No nā neodymium magnet i hoʻohana ʻia, hiki ke hoʻomaʻemaʻe ʻia a mālama mau ʻia e hōʻoia i kā lākou hana paʻa.

I ka hopena:

Ma o ka hōʻuluʻulu manaʻo o kēia ʻatikala, hiki iā mākou ke hoʻomaopopo i nā kumu nui o ka hoʻomākaukau, ka hana ʻana a me ka hoʻohana ʻana i nā magnet neodymium.

B. No ka hoʻomohala ʻana o nā magnet neodymium e hiki mai ana, hiki ke ʻimi hou ʻia nā ʻenehana hoʻomākaukau hou a me nā ʻano hana lapaʻau e hoʻomaikaʻi i kā lākou hana a me ka laulā noi, a hoʻolaha i kā lākou noi ma nā kahua e puka mai ana.
