He aha ka mea PrNd?
ʻO nā mea PrNd, i ʻike ʻia ʻo Praseodymium-Neodymium, he ʻano omea lepo laha olei loaʻa ka manaʻo nui i nā makahiki i hala iho nei ma muli o kāna mau waiwai magnetic.He mea koʻikoʻi kēia mea i ka hana ʻana i nā magnet ikaika, ʻo ia hoʻi nā magnet PrNd, i hoʻohana nui ʻia i nā ʻoihana like ʻole, me ka uila, automotive, a me ka ikehu hou.
Ua ʻike ʻia nā mea hoʻokalakupua honua, me nā magnet PrNd, no ko lākou ikaika ʻokoʻa a me nā waiwai magnetic.Pono lākou i ka hana ʻana i nā huahana he nui, mai nā mea uila uila a hiki i nā mea lapaʻau kiʻekiʻe.ʻO nā hiʻohiʻona kūʻokoʻa oPrNd meae lilo ia i kumu waiwai nui no ka ʻenehana hou a me ka hana hou.
Hoʻokumu ʻia nā mea magnet PrNd me ka hui pū ʻana o praseodymium a me neodymium, ʻelua mau mea honua laha ʻole e hōʻike ana i nā waiwai magnetic ikaika.Kaulana ʻia kēia mau mea magnet no ko lākou ikaika magnetic kiʻekiʻe, e hoʻolilo iā lākou i mea kūpono no nā noi e koi ana i kahi kahua magnetic compact a ikaika.ʻO ka hoʻohana ʻana oPrNd magnetsua hoʻololi i ka hoʻolālā a me ka hana o nā mea like ʻole, hiki ke hoʻomohala i nā huahana liʻiliʻi, māmā, a ʻoi aku ka maikaʻi.
Hiki ke hoʻopili ʻia nā waiwai magnetic o PrNd magnet i ke ʻano atomic kūikawā o praseodymium a me neodymium.Loaʻa kēia mau mea i nā electrons i hoʻopaʻa ʻole ʻia, e hāʻawi ana i ko lākou māla ikaika.Ke hui pū ʻia ma ke ʻano o ka magnet, hōʻike ʻia nā mea PrNd i kahi mana kupaianaha e huki a hoʻopaʻa i nā koina magnetic, e lilo ia i kumu waiwai nui no nā noi ʻenehana a me ka ʻenehana.
ʻO kekahi o nā pōmaikaʻi nui o nā magnet PrNd ko lākou coercivity kiʻekiʻe, e pili ana i ko lākou hiki ke pale aku i ka demagnetization.ʻO kēia waiwai ka mea i hilinaʻi nui ʻia a paʻa hoʻi, e hōʻoiaʻiʻo ana e paʻa mau ke kahua magnetic i nā manawa lōʻihi o ka hoʻohana ʻana.ʻO ka hopena, ua hoʻohana nui ʻia nā magnet PrNd i nā noi i kū like a mehana māneʻe hilinaʻihe mea nui ia, e like me nā mīkini uila, nā mīkini hoʻohālikelike magnetic (MRI), a me nā mea hoʻokaʻawale magnetic.
Ma waho aʻe o ko lākou ikaika magnetic ʻokoʻa, mahalo ʻia nā magnet PrNd no kā lākou huahana ikehu kiʻekiʻe, ʻo ia ke ana o ka nui o ka ikehu kiʻekiʻe i hiki i kahi magnet ke hāʻawi.Hana kēia ʻanoPrNd magnetsʻoi aku ka maikaʻi o ka hoʻololi ʻana i ka ikehu uila i ka neʻe ʻana o ka mīkini, e lilo ai lākou i mea nui i ka hoʻomohala ʻana i nā ʻenehana holomua, e like me nā kaʻa uila, nā makani makani, a me nā ʻōnaehana levitation magnetic.
ʻO ka hoʻohana nui ʻana o nā magnet PrNd i nā ʻoihana like ʻole e hōʻike ana i ko lākou koʻikoʻi i ka hoʻokele ʻana i nā holomua ʻenehana a me nā mea hou.Mai ka hoʻonui ʻana i ka hana o nā kaʻa uila a hiki i ka hiki ʻana i ka miniaturization o nā mea uila, hoʻokani ʻo PrNd magnets i kahi hana koʻikoʻi i ka hana ʻana i ka honua hou.
Eia nō naʻe, he mea nui e hoʻomaopopo i ka hana ʻana o nā magnet PrNd e hilinaʻi i ka unuhi a me ka hoʻoili ʻana i nā mea o ka honua laha ʻole, hiki ke loaʻa nā hopena kūlohelohe a me ka geopolitical.No laila, ke hana ʻia nei nā hana e ʻimi i nā hana hoʻomau noka ʻeli ʻana o ka ʻāina rarea me ka hoʻomohala ʻana i nā mea ʻē aʻe e hiki ke hōʻemi i ka hilinaʻi ʻana i nā mea ʻano honua rare.
I ka hopena, ʻo nā mea PrNd, ʻoi aku ma ke ʻano o nā magnet PrNd, e hōʻike ana i kahi pōhaku kihi o ka ʻenehana hou, e hāʻawi ana i ka ikaika magnetic a me ka hana.Ke hoʻomau nei ka noi no nā magnets kiʻekiʻe, ʻaʻole hiki ke hoʻonui ʻia ke koʻikoʻi o nā mea PrNd i ka hoʻokele ʻana i ka hana hou a me ka holomua ʻenehana.Me ka hoʻomau ʻana o ka noiʻi a me ka hoʻomohala ʻana, ua mākaukau nā noi kūpono o PrNd magnets e hoʻonui, e hoʻopaʻa hou i kā lākou kuleana i ka hana ʻana i ka wā e hiki mai ana o ka ʻenehana a me ka ʻoihana.
