I loko o ka nohona o kēia mau lā kahi e hoʻohana nui ʻia ai nā mea magnetic, ʻokoʻa nā huahana samarium cobalt a me nā huahana neodymium iron boron. No ka poʻe hoʻomaka i ka ʻoihana, he mea nui e koho i nā mea i kūpono i kāu huahana. I kēia lā, e nānā hohonu kākou i nā hiʻohiʻona o kēia mau mea ʻokoʻa ʻelua a ʻike i ka mea i kūpono i kāu mau pono.
1. Hoʻohālikelike hana
Nā waiwai mākēneki
ʻO NdFeB ka mea ikaika loa i ʻike ʻia me ka huahana ikehu magnetic kiʻekiʻe loa. Hana maikaʻi kēia i nā hiʻohiʻona noiʻi e koi ai i kahi kahua magnetic ikaika. No ka laʻana, ma ke kahua o nā kaʻa, hiki i nā kaʻa e hoʻohana ana i nā magnet mau loa NdFeB ke hoʻoulu i ka torque nui aʻe a hāʻawi i ka mana ikaika no nā mea hana. ʻAʻole pono e hoʻohaʻahaʻa ʻia nā waiwai magnetic o SmCo mau magnet. Hiki iā lākou ke mālama i ke kūpaʻa magnetic maikaʻi ma nā wahi wela kiʻekiʻe. ʻO kēia hiʻohiʻona o SmCo e kū i waho i kekahi mau wahi ʻoihana kūikawā me nā koi wela kiʻekiʻe.
Paʻa wela
ʻO kekahi o nā mea maikaʻi loa o nā huahana SmCo ʻo ia kona kūpaʻa wela maikaʻi loa. Ma nā wahi wela kiʻekiʻe, ʻoi aku ka liʻiliʻi o ka palaho o ka SmCo mau mākēneki ma mua o ka NdFeB. ʻO ka ʻokoʻa, ʻoiai he mau waiwai magnetic ko NdFeB, ʻano nāwaliwali kona ʻae ʻana i ka wela, a hiki ke hoʻihoʻi ʻia ka demagnetization i nā wela kiʻekiʻe.
ʻO ke kūpaʻa ʻino
Ma ke ʻano o ka pale ʻana i ka corrosion, ʻoi aku ka maikaʻi o nā mea SmCo i kekahi mau wahi kinoea haʻahaʻa a corrosive ma muli o ko lākou mau waiwai kemika paʻa. Eia nō naʻe, inā ʻaʻole i loaʻa i nā mea NdFeB nā pale pale kūpono, hiki iā lākou ke ʻino i nā wahi like, e pili ana i kā lākou hana a me ke ola lawelawe. Eia nō naʻe, me ka hoʻomohala ʻana i ka ʻenehana lapaʻau ʻili, ke hoʻomaikaʻi mālie nei ke kūpaʻa corrosion o NdFeB.
2. Nā kahua noi
Nā kahua noi o nā huahana SmCo
Hoʻohana nui ʻia ʻo Samarium cobalt mau mea magnet ma nā kahua kiʻekiʻe e like me ka aerospace, pūʻali koa, a me nā lāʻau lapaʻau. Ma ka ʻōnaehana hoʻomalu o nā ʻenekini mokulele, hiki i nā SmCo mau magnet ke hana paʻa i ke kiʻekiʻe kiʻekiʻe a me ka paʻakikī mechanical vibration environment e hōʻoia i ka mana pololei o ka ʻenekini. Ma ka ʻōnaehana alakaʻi missile a me nā ʻāpana hoʻokele manaʻo o nā satelite i ke kahua kaua, makemake pū ʻia nā mea SmCo no kā lākou kiʻekiʻe kiʻekiʻe a me ke kūpaʻa kiʻekiʻe. I nā lāʻau lapaʻau, e like me kekahi mau mea hoʻokalakupua i loko o nā mea hoʻonaninani magnetic resonance (MRI), ka hoʻohana ʻana o SmCo mau mea paʻa e hōʻoia i ka pololei o nā mea hana ma lalo o nā kūlana hana lōʻihi a kiʻekiʻe.
Nā kahua noi o nā huahana NdFeB
Ua hoʻohana nui ʻia nā mea magnet permanent NdFeB ma ke kahua kīwila ma muli o ko lākou mau waiwai magnetic ikaika a me ke kumu kūʻai haʻahaʻa. No ka laʻana, i loko o kā mākou huahana uila mea kūʻai maʻamau e like me ka paʻa paʻa, nā mea kelepona kelepona, a me nā headphone, hāʻawi nā NdFeB mau magnets iā lākou i kahi māla liʻiliʻi a ikaika. I nā kaʻa o nā kaʻa ikehu hou, ua hoʻomaikaʻi maikaʻi ʻia ka noi o NdFeB i ka pono o nā kaʻa a hāpai i ka hoʻomohala ʻana i ka ʻoihana kaʻa ikehu hou. Eia kekahi, he hana koʻikoʻi ʻo NdFeB i nā ʻano kaʻa like ʻole, nā mea ʻike a me nā mea hana ʻē aʻe ma ke kahua o ka ʻenehana ʻoihana.
3. Nā kumu kūʻai
Kumukuai maka
ʻO nā mea nui o SmCo mau mea magnet, samarium a me cobalt, he mau mea metala kakaikahi, a he kiʻekiʻe kā lākou mining a me ka hoʻomaʻemaʻe ʻana i nā kumukūʻai, e alakaʻi ana i ke kumukūʻai kiʻekiʻe o nā kumu waiwai no nā huahana SmCo. Ma waena o nā mea nui o NdFeB, neodymium, hao a me boron, hao a me boron he mau mea maʻamau a maʻalahi. ʻOiai ʻo ka neodymium he mea laha ʻole ka honua, loaʻa iā NdFeB kekahi mau pono i nā kumukūʻai maka i hoʻohālikelike ʻia me SmCo.
Uku hana
I ka wā o ka hana ʻana, paʻakikī nā mea SmCo e hana ma muli o ko lākou paʻakikī kiʻekiʻe a me nā ʻano ʻē aʻe, a ʻoi aku ka kiʻekiʻe o ke kumukūʻai. He mea maʻalahi nā mea NdFeB i ka hana, akā ma muli o kā lākou oxidation maʻalahi a me nā hiʻohiʻona ʻē aʻe, koi ʻia nā ʻano pale kūikawā i ka wā o ka hana ʻana, e hoʻonui ai i ke kumukūʻai hana i kekahi ʻano.
4. Pehea e koho ai i ka huahana kūpono iā ʻoe
E noʻonoʻo i ka mahana hana
Inā hoʻohana ʻia ka huahana i kahi kaiapuni kiʻekiʻe, e like me ka ʻoi aku ma mua o 150 ℃ a i ʻole ke kiʻekiʻe aʻe, e like me kahi kokoke i nā kapuahi ʻenehana kiʻekiʻe a me nā mea magnetic a puni nā ʻenekini aerospace, ʻoi aku ka maikaʻi o nā huahana samarium cobalt. No ka mea hiki i kona kūpaʻa i nā wela kiʻekiʻe ke hōʻoia i ka hana kūpaʻa lōʻihi a pale i nā pilikia demagnetization ma muli o ka piʻi ʻana o ka mahana. Inā aia ka mahana hana ma ka lumi wela a i ʻole ma lalo o 100 ℃, e like me ka hapa nui o nā huahana uila kīwila, nā motika ʻenehana nui, a me nā mea ʻē aʻe, hiki i nā huahana NdFeB ke hoʻokō i nā pono a hiki ke hāʻawi i ka pāʻani piha i kā lākou mau waiwai magnetic kiʻekiʻe.
E noʻonoʻo i nā koi pale corrosion
Inā hoʻohana ʻia ka huahana i loko o kahi kaiapuni haʻahaʻa, corrosive kinoea, e like me nā ʻāpana magnetic i nā mea hana i nā kaiapuni e like me ke kahakai a me nā mea kanu kemika, pono e noʻonoʻo ʻia ka pale ʻana o ka mea. ʻO ka paʻa paʻa o ka samarium cobalt material ponoʻī e ʻoi aku ka maikaʻi o kēia kaiapuni. Eia nō naʻe, inā mālama ʻia ka huahana NdFeB me kahi pale pale kiʻekiʻe, hiki iā ia ke hoʻokō i nā koi pale corrosion i kekahi ʻano. I kēia manawa, pono e noʻonoʻo pono i ke kumukūʻai a me ka hopena palekana e koho ai.
Ke kaupaona nei i ka waihona kālā
Inā ʻaʻole ʻo ke kumukūʻai ke kumu palena nui, a ʻoi aku ka kiʻekiʻe o ka hana a me nā koi kūpaʻa, e like me ka pūʻali koa, nā mea lapaʻau kiʻekiʻe kiʻekiʻe a me nā kahua ʻē aʻe, ʻo ke kiʻekiʻe kiʻekiʻe a me ka paʻa o nā huahana samarium cobalt hiki ke hōʻoia i ka hana hilinaʻi o ka mea lako. Eia nō naʻe, inā he huahana kīwila nui ia, he mea koʻikoʻi ka hoʻokele kumukūʻai. Hiki i nā huahana NdFeB ke hōʻemi pono i nā kumukūʻai ʻoiai e hālāwai ana i nā koi o ka hana me kā lākou kumu haʻahaʻa haʻahaʻa a me nā kumukūʻai hana.
Koi makeke
No kekahi mau noi e koi ana i ka pololei a me ka paʻa o ka māla magnetic kiʻekiʻe, e like me nā ʻōnaehana alakaʻi missile a me nā ʻāpana magnetic i nā mea hoʻāʻo lapaʻau kiʻekiʻe kiʻekiʻe, ʻoi aku ka kiʻekiʻe a me ka hana paʻa magnetic o nā huahana samarium cobalt me nā koi. No kekahi mau kaʻa ʻoihana maʻamau, nā mea hoʻohana uila, a me nā mea ʻē aʻe ʻaʻole koi i ka pololei kiʻekiʻe akā makemake i ka ikaika o ka māla magnetic, hiki i nā huahana neodymium iron boron ke hana maikaʻi i ka hana.
ʻAʻohe ʻokoʻa loa ma waena o nā huahana samarium cobalt a me nā huahana neodymium iron boron. Ke koho ʻana i kēia mau mea magnetic maikaʻi loa, pono ʻoe e hana i kahi hoʻohālikelike piha. Manaʻo ka kaʻana like ʻana i luna e kōkua i nā mea a pau e loaʻa nā huahana e kūpono i kā lākou pono!
