ʻO ke kaʻina hana o nā neodymium magnets e like me ka hana ʻana i nā pōhaku lepo i hoʻopaʻa ʻia i loko o kahi umu wela wela. Me ka mālama ʻana i nā wela kiʻekiʻe, hana ia i ka pōhaku paʻa a ikaika.
ʻO ke kaʻina hana nui no nā magnet neodymium ʻo ke kaʻina sintering, ʻo ia ke kumu i kapa ʻia ai mākou he sintering neodymium magnets. ʻO nā mea nui he neodymium (Nd 32%), Ferrum (Fe 64%) a me Boron (B 1%), ʻo ia ke kumu i kapa ai mākou i nā magnet neodymium e lilo i mau magnet NdFeB. Mālama ʻia ke kaʻina hana sintering me ke kinoea inert (e like me ka nitrogen, argon a i ʻole helium gas) i loko o ka umu ahi, no ka mea he liʻiliʻi nā ʻāpana magnetic e like me 4 microns, maʻalahi hiki ke puhi ʻia, inā ʻike ʻia i ka lewa, maʻalahi e oxidized a hopu i ke ahi, no laila pale mākou iā lākou me ke kinoea inert i ka wā o ka hana ʻana, a ma kahi o 48 mau hola i loko o ka umu sintering. Ma hope wale nō o ka sintering hiki iā mākou ke hoʻokō i nā ingots magnet paʻa a ikaika.
He aha ka magnet ingots? Loaʻa iā mākou nā ʻāpana magnetic i kaomi ʻia i loko o kahi mold a i ʻole mea hana, inā makemake ʻoe i ka disc magnet, a laila loaʻa iā mākou ka palaka disc, inā makemake ʻoe i ka magnet block, a laila loaʻa iā mākou i ka mold bock, kaomi ʻia nā ʻāpana magnetic i loko o ke kila kila a puka i waho. magnet ingots, a laila loaʻa iā mākou kēia mau mea magnet ingots wela i mālama ʻia i loko o kahi umu sintering e loaʻa ai kahi kūlana paʻa. ʻO ka nui o nā ingots ma mua o ka sintering ma kahi o 50% o ka nui maoli, akā ma hope o ka sintering, ʻo 100%. ʻO ka nui o ka neodymium magnet he 0.0075 grams no ka millimeter cubic. Ma o kēia kaʻina hana, e emi ana ke ana o ka magnet ingots ma kahi o 70% -80% a ua hoʻemi ʻia ko lākou leo ma kahi o 50%. ʻO ka ʻelemakule o ka magnet ingots ma hope o ka sintering e hoʻoponopono i nā waiwai o nā metala.
Hoʻonohonoho ʻia nā waiwai magnetic kumu ma hope o ka pau ʻana o ka sintering a me nā kaʻina hana kahiko.
Hoʻopaʻa ʻia nā ana waiwai magnetic nui me ka remanence flux density, coercivity, a me ka huahana ikehu kiʻekiʻe i ka faila. ʻO kēlā mau magnet wale nō i hala i ka nānā ʻana e hoʻouna ʻia i nā kaʻina hana aʻe no ka mīkini hou, plating, magnetizing a hana i ka hui hope, etc.
ʻO ka mea maʻamau, hoʻokō mākou i nā koi hoʻomanawanui o ka mea kūʻai aku ma o ka mīkini, wili a me nā abrasives, e like me ka magnet slicing e like me ka CNC machining, a me nā mea ʻē aʻe mākou e hana i nā mīkini kūikawā e hana i nā hana like ʻole ma nā magnets. Nui nā hana e hoʻokō ai i nā koi kūikawā o ka mea kūʻai aku.
