Nā Mākēneki NdFeB i hoʻopaʻa ʻia
ʻO NdFeB paʻa, i haku ʻia me Nd2Fe14B, he magnet synthetic. ʻO nā magnet NdFeB i hoʻopaʻa ʻia he mau magnet i hana ʻia e ka "press molding" a i ʻole "injection molding" ma ka hui ʻana i ka pauka magnetic NdFeB i hoʻopau wikiwiki ʻia a me ka mea hoʻopili. He kiʻekiʻe ke kiʻekiʻe o nā magnet i hoʻopaʻa ʻia, hiki ke hana ʻia i mau ʻāpana magnetic me nā ʻano paʻakikī, a loaʻa nā hiʻohiʻona o ka hoʻoheheʻe ʻana i hoʻokahi manawa a me ka orientation multi-pole. Loaʻa i ka NdFeB Bonded ka ikaika mechanical kiʻekiʻe, a hiki ke hana ʻia i ka manawa hoʻokahi me nā mea kākoʻo ʻē aʻe.
Ua ʻike ʻia nā magnet i hoʻopaʻa ʻia a puni ka makahiki 1970 i ka wā i kūʻai ʻia ai ʻo SmCo. He maikaʻi loa ke kūlana mākeke o nā magnet paʻa paʻa, akā paʻakikī ke hana pololei iā lākou i loko o nā ʻano kūikawā, a ua maʻalahi lākou i ka haki ʻana, ka pōʻino, ka poho o ka ʻaoʻao, nā kihi kihi a me nā pilikia ʻē aʻe i ka wā o ka hana. Eia kekahi, ʻaʻole maʻalahi lākou e hōʻuluʻulu, no laila ua kaupalena ʻia kā lākou noi. No ka hoʻoponopono ʻana i kēia pilikia, ʻāwili ʻia nā magnet mau loa, hui pū ʻia me ka plastic, a kaomi ʻia i loko o kahi māla magnetic, ʻo ia paha ke ʻano hana mua loa o nā magnet paʻa. Ua hoʻohana nui ʻia nā magnet NdFeB i hoʻopaʻa ʻia ma muli o ko lākou kumu kūʻai haʻahaʻa, kiʻekiʻe kiʻekiʻe ka pololei, ke kūʻokoʻa nui o ke ʻano, ka ikaika mechanical maikaʻi, a me ka umekaumaha kikoʻī māmā, me ka ulu makahiki o 35%. Mai ka puka ʻana mai o NdFeB pauka magnet paʻa, ua hoʻokō wikiwiki nā mea hoʻopaʻa paʻa ma muli o kāna mau waiwai magnetic kiʻekiʻe.
