Ke hoʻomau nei ka ʻenehana i ka holomua, he hana koʻikoʻi ka mana ʻike ʻole ma hope o nā hiʻohiʻona - magnets.Ua hoʻololi kēia mau mea ikaika i nā ʻoihana mai ka uila a hiki i ka ikehu hou.Ma waena o nā mea magnet he nui i loaʻa,NdFeB magnethoʻomalu, hāʻawi i ka ikaika ʻole a me ka versatility.
No laila, he aha nā mea magnet NdFeB?ʻO ka NdFeB ke kū nei no ka neodymium iron boron a he mea hoʻokalakupua honua i haku ʻia me ka neodymium, ka hao a me ka boron.Ua ʻike ʻia nā magnet rare earth no kā lākou mau waiwai magnetic maikaʻi loa, e hana ana iā lākou i mea koʻikoʻi i nā ʻano noi like ʻole.
Ma muli o kā lākou haku mele ʻokoʻa, loaʻa i nā mea magnet NdFeB ka ikaika o ke kahua magnetic i ʻoi aku ma mua o nā magnet mau loa.ʻO ko lākou ikaika kiʻekiʻe ka mea i koho mua ʻia no nā ʻoihana e koi ana i nā lako magnetic compact akā ikaika.Mai ka lolouila paakiki a hiki i ke kaa uila,NdFeB magnethoʻonui i ka hana a me ka pono.
ʻOiai ʻo ko lākou liʻiliʻi liʻiliʻi, he kuleana koʻikoʻi nā magnet NdFeB i ka ʻāpana ikehu hou.He mea nui ia no ka makani turbine, e hiki ai ke hoololi i ka ikehu mai ka ikehu mechanical i ka ikehu uila.I loko o nā kaʻa uila, hoʻohana ʻia nā magnet NdFeB i nā kaʻa uila ikaika e hoʻomaikaʻi i ka wikiwiki a me ka hana holoʻokoʻa.
ʻO ka ʻoihana aerospace kekahi pōmaikaʻi nui maiNdFeB magnet.Hoʻohana ʻia lākou i nā noi like ʻole e like me nā ʻōnaehana alakaʻi, actuators a me nā sensor.ʻO ko lākou liʻiliʻi liʻiliʻi, i hui pū ʻia me ka ʻoi aku ka ikaika o ke kahua magnetic, kūpono lākou no nā kaiapuni i kaupalena ʻia.
Ma ke kahua lapaʻau,NdFeB magnetua hōʻoia i ka hana koʻikoʻi i nā lako diagnostic holomua e like me nā mīkini MRI.ʻO kā lākou mau māla magnetic ikaika e kōkua i ka hana ʻana i nā kiʻi kikoʻī o ke kino o ke kanaka, e kōkua ana i ka ʻike ʻana a me ka nānā ʻana i nā kūlana like ʻole.Hoʻohui ʻia, hoʻohana ʻia lākou i nā implants olakino, e like me nā pacemakers, e hoʻomaʻamaʻa i ka hana pololei.
He mea pono e hoʻomaopopo i ka mālama kūikawā e like meNdFeB magnethiki loa i ka corrosion.E hoʻopili i kahi uhi e like me ka nickel, zinc a epoxy paha e pale ai i ka magnet mai nā mea kūlohelohe.Eia hou, ikaika loa nā māneta NdFeB a hiki ke hoʻopilikia i ka palekana inā ʻaʻole mālama ʻia me ka mālama.
I ka hōʻuluʻulu ʻana, ua hoʻololi nā mea magnet NdFeB i nā ʻoihana like ʻole me ko lākou ikaika kiʻekiʻe a me ka laulā o nā noi.Mai ka uila a hiki i ka ikehu hou a me nā mea lapaʻau, hoʻomau kēia mau mea hoʻokalakupua honua i ka hana koʻikoʻi i ka mana o ka honua hou.Ke holomua nei ka ʻenehana, hiki iā mākou ke manaʻo i nā holomua hou aʻeNdFeB magnetʻenehana, wehe i nā mea hiki hou a hoʻonui i ka laulā o nā noi.
