ʻO ka "mana luku" o ka magnetism ikaika

Hoʻolauna i nā mea Mākēneki ikaika
Ua hoʻohana nui ʻia nā mea magnetic ikaika, ʻoi aku ka paʻa mau mea like me ka neodymium iron boron (NdFeB) a me ka samarium cobalt (SmCo), i ka ʻoihana hou ma muli o ko lākou ikaika ikaika a me ka hana maikaʻi loa. Mai nā kaʻa a hiki i nā mea lapaʻau, mai nā mea uila uila a i ka aerospace, he mea nui kēia mau mea. ʻOiai ua hoʻohana ʻia nā mea magnetic ikaika i nā kula he nui, ʻaʻole hiki ke mālama ʻia ko lākou mau pōʻino. E aʻo kākou i ke ʻano o ka hana ʻana i nā mea magnetic ikaika, hoʻomaopopo maikaʻi i nā pilikia e hiki mai ana, a pale aku iā lākou.

Pehea ka ikaika o nā mea magnetic i hānau ʻia
1. Hoʻomākaukau mea maka: ʻO ka hana mua i ka hana ʻana i nā mea magnetic ikaika ka hoʻomākaukau ʻana i nā mea maka. No NdFeB, ʻo nā mea waiwai nui ka neodymium, ka hao, ka boron a me nā mea ʻē aʻe e like me dysprosium a me praseodymium. Pono e hoʻopaʻa ʻia a hoʻopaʻa ʻia nā mea maka e hōʻoia i ka hoʻomaʻemaʻe ʻana a me ka hoʻohui ʻana i nā koi.
2. Heheʻe: Hoʻokomo ʻia nā mea maka i hoʻomākaukau ʻia i loko o kahi umu induction vacuum no ka hoʻoheheʻe ʻana e hana i kahi alloy. Ma kēia kaʻina hana, koʻikoʻi loa ka hoʻomalu ʻana i ka wela a pono e hoʻokō ʻia ma kahi wela kiʻekiʻe ma mua o 1000°C. E ninini ʻia ka wai huila i hoʻoheheʻe ʻia i loko o kahi moʻo e hoʻomaloʻo a hana i kahi ingot.
3.ʻO ka ʻohi ʻana a me ka wili: Pono e nahaha liilii ka ingot i hooluuia e ka mea wiliwili, a laila e wili hou ia i pauda maikai e ka wili poepoe. ʻO ka nui o ka nui o ka pauka maikaʻi e pili pono i ka maikaʻi o ke kaʻina hana ma hope, no laila he mea nui kēia kaʻina.
4. Ke kaomi ʻana: Hoʻokomo ʻia ka pauda maikaʻi i loko o kahi ʻeleʻele a laila hoʻonohonoho ʻia a kaomi ʻia ma lalo o ka hana a kahi māla ikaika. ʻO kēia ka mea e hōʻoiaʻiʻo ai i ke kuhikuhi ʻana o nā ʻāpana pauka magnetic, e hoʻomaikaʻi ai i nā waiwai magnetic o ka huahana hope. ʻO ka huahana ma hope o ke kaomi ʻana i kapa ʻia ʻo "kino ʻōmaʻomaʻo".
5. Hoʻopaʻa ʻana: Hoʻokomo ʻia ke kino ʻōmaʻomaʻo i loko o ka umu hoʻoheheʻe a hoʻopaʻa ʻia i ke kiʻekiʻe kiʻekiʻe (e pili ana i 1000 ° C-1100 ° C) e hoʻopaʻa a hana i kahi magnet paʻa. I ka wā o ke kaʻina hana sintering, hoʻololi ka mea i nā hoʻololi kino a me nā kemika, a i ka hopena i hana ʻia i kahi huahana me nā waiwai magnetic kiʻekiʻe.
6. Ka hana ʻana a me ka mālama ʻana i ka ʻili: Pono e ʻoki ʻia ka magnet sintered, hoʻomaʻamaʻa ʻia a me nā hana mīkini ʻē aʻe e hoʻokō i ke ʻano a me ka nui i makemake ʻia. I mea e pale ai i ka magnet mai ka oxidation a i ʻole corrosion i ka wā e hoʻohana ai, ua uhi ʻia kahi papa pale e like me ka nickel, zinc a i ʻole epoxy resin ma luna o kona ʻili.
7. Mākēneki: ʻO ka hana hope loa, ʻo ia ka hoʻokalakupua i ka magnet e hāʻawi iā ia i nā waiwai magnetic e pono ai. Hoʻohana pinepine ʻia ka magnetization i loko o kahi mea hana magnetization kūikawā, me ka hoʻohana ʻana i kahi māla magnetic ikaika e hana i nā kāʻei magnetic i loko o ka magnet.

ʻO ka pōʻino o ka magnetism ikaika
Hōʻike nui ʻia ka lethality o nā mea magnetic ikaika i nā ʻano aʻe:

1. Ka hopena ma nā mea uila: Hiki i nā mea magnetic ikaika ke hoʻopilikia i ka hana ʻana o nā mea uila, ʻoi aku ka nui o nā mea e hilinaʻi nei i nā mea ʻike magnetic. No ka laʻana, hiki ke hoʻopili ʻia nā kelepona paʻa lima, nā paʻa paʻa kamepiula, nā kāleka hōʻaiʻē, a me nā mea ʻē aʻe e nā māla magnetic ikaika, e hopena ai i ka nalowale ʻikepili a i ʻole nā ​​lako hana.
2.Ka hopena ma ke kino o ke kanaka: ʻOiai ʻaʻole hoʻoweliweli nā mea magnetic ikaika i ke kino o ke kanaka, hiki iā lākou ke hoʻoulu i ka ʻeha a i ʻole ka hōʻoluʻolu ke ʻai ʻia a pili ʻia paha me ka ʻili. Eia hou, hiki i nā mea magnetic ikaika ke huki i nā mea metala kokoke a hoʻopilikia i nā pōʻino.
3.Ka hopena i nā mea magnetic ʻē aʻe: Hiki i nā mea ʻumeke ikaika ke huki a hoʻoneʻe i nā mea ʻē aʻe, e hāʻule ai nā mea kaumaha a i ʻole e pohō nā mea hana inā ʻaʻole mālama pono ʻia. No laila, i ka hoʻohana ʻana i nā mea magnetic ikaika, pono e lawe ʻia nā hana palekana kūpono e pale aku i nā pilikia pono ʻole.
4.Ka hopena i nā mea hana mechanical: I kekahi mau hihia, hiki ke hoʻopili ʻia nā ʻāpana metala i nā mea hana mechanical, e hoʻopau ai i nā mea hana. He mea koʻikoʻi kēia hopena i nā mea kani pololei a me nā mea lapaʻau.

Pehea e pale ai i nā hopena o ka magnetism ikaika
1. E mālama i kou mamao: E hoʻokaʻawale i nā mea magnetic ikaika mai nā mea uila, kāleka hōʻaiʻē a me nā mea koʻikoʻi ʻē aʻe.
2. Nā hana pale: E hoʻohana i nā mea pale kūpono i ka wā e lawelawe ai i nā mea magnetic ikaika a pale i ka hoʻopili pololei ʻana me ka ʻili.
3. Hoʻonaʻauao a me nā ʻōlelo aʻo: E hoʻonaʻauao i nā keiki e pāʻani ʻole me nā mea pāʻani ikaika a hoʻomaopopo pono lākou i nā pōʻino.
4. Alakaʻi ʻoihana: Ma nā wahi lapaʻau, e hōʻoia i ka poʻe maʻi a me nā limahana e hoʻomaopopo i nā lula palekana no nā mea magnetic ikaika a lawe i nā hana palekana kūpono.
5. Ka waiho ʻana a me ka lawe ʻana: Pono e mālama ʻia nā mea magnetic ikaika i loko o nā pahu kūikawā a pale pono i ka wā o ka lawe ʻana i mea e pale ai i ka hoʻopili ʻana me nā mea ʻē aʻe.

ʻO ke kaʻina hana o nā mea magnetic ikaika he kaʻina paʻakikī a paʻakikī e pili ana i nā ʻanuʻu he nui a me nā ʻano loea loea. ʻO ka hoʻomaopopo ʻana i kāna kaʻina hana e kōkua iā mākou e hoʻomaopopo a hoʻohana i kēia mau mea. I ka manawa like, pono mākou e makaʻala i nā pōʻino o nā mea magnetic ikaika a lawe i nā hana pale pono e hōʻoia i ko mākou palekana.
