Hana ʻia nā mea magnet Neodymium i hoʻopaʻa ʻia me ka mea ikaika Nd-Fe-B i hui pū ʻia i loko o kahi binder epoxy.ʻO ka hui ʻana ma kahi o 97 vol% magnet material i 3 vol% epoxy.ʻO ke kaʻina hana e hoʻohui i ka pauka Nd-Fe-B me kahi mea hoʻopili epoxy a me ka hoʻopili ʻana i ka hui ʻana i loko o kahi paʻi a hoʻōla i ka ʻāpana i ka umu.No ka mea ua hoʻokumu ʻia ka mea e ka hoʻopili paʻa ʻana, ʻokoʻa nā ana .002 ″ a ʻoi aku ka maikaʻi no ka holo i hāʻawi ʻia. Hoʻohana nui ʻia ka Bonded Compression Molded NdFeB Magnets no ka mold maʻalahi a me nā waiwai magnetic kiʻekiʻe.Hiki iā lākou ke hoʻokomo i ka mold me nā ʻāpana ʻē aʻe.
ʻO ka hui piha ʻana o ke kaʻina hana injecting a me ka pauda rare-earth waiwai kiʻekiʻe e hiki ai ke hana i kahi mea hoʻopaʻa maʻalahi Ndfeb apo magnet no ka mea haʻiʻōlelo.Loaʻa i nā Bonded Neodymium Magnets ka maikaʻi o nā ʻano kiʻekiʻe i hoʻohālikelike ʻia me Sintered Magnets.Pono e uhi ʻia ka magnet me kahi papa o ka epoxy ʻeleʻele a hina paha a i ʻole Parylene e pale aku iā lākou mai ka ʻino.
Hoʻokaʻawale ʻia nā magnet NdFeB Hot-pressed i ʻelua ʻano, Hot pressed isotropic NdFeB (MQ 2) a me ka wela-extruded anisotropic NdFeb magnet (MQ 3). ma o ka compression.The hot-pressed anisotropic NdFeB magnet is mainly anisotropic radially-oriented ring magnet which is produced by compression and extrusion deformation by rapidly quenched NdFeB magnetic powder under high temperature.Customized Injection Bonded NdFeB Ring Magnets
ʻO nā magnet neodymium-iron-boron (NdFeB) i hoʻopaʻa ʻia he mau magnet ikaika i hoʻohana ʻia no nā noi like ʻole.Hoʻohana maʻamau ʻia ka uhi ʻana o Epoxy no nā magnet NdFeB paʻa;Hoʻohana pū ʻia ka nickel plating electroless e pale i ka corrosion.Hiki ke hoʻopaʻa ʻia nā mea NdFeB i hoʻopaʻa ʻia i ka isotropic i kēlā me kēia ʻaoʻao, a i ʻole me nā pou he nui.
ʻO ka mea i hoʻopaʻa ʻia ʻo Nd-Fe-B he isotropic, no laila hiki ke magnetized ma o kekahi ʻaoʻao, me nā hoʻonohonoho multi-polar.No ka mea aia ka mea i loko o ka epoxy binder, hiki ke hana ʻia ma ka wili a i ʻole ka lathe.Akā naʻe, ʻaʻole e kākoʻo ka mea i kahi kaula, no laila ʻaʻole hiki ke paʻi i nā lua.Hoʻohana pinepine ʻia nā mea Nd-Fe-B i hoʻopaʻa ʻia e hōʻemi nui i ka nui o nā hoʻolālā i hoʻohana i nā mea magnet seramika.Hiki ke hoʻemi ʻia ka nui no ka mea ʻoi aku ka ikaika o ka mea ma mua o ka mea magnet ceramic.Eia kekahi, no ka mea he isotropic ka mea, hiki ke magnetized multi-polar, e like me ke ʻano NSNS ma ke anawaena o waho o ke apo.
Hoʻopaʻa NdFeB magnets i kiʻekiʻe remanence, kiʻekiʻe coercivity, kiʻekiʻe ikehu huahana, kiʻekiʻe hana a me ke kumu kūʻai lākiō, maʻalahi i ka hana likeʻole nui, a me ka palena iki kiko'ī advantage.They hiki ke no medina wae me kekahi mau mea, hoʻohana nui no ka pōkole-makahiki, uuku. , nā huahana uila māmā a lahilahi.
ʻOi aku ka ikaika o ka magnet Bonded NdFeb ma mua o nā magnet i hoʻoheheʻe ʻia, loaʻa nō hoʻi ka maikaʻi o nā ʻano kiʻekiʻe i hoʻohālikelike ʻia me nā magnet sintered.Kiʻekiʻe coercivity, kiʻekiʻe ikehu huahana, corrosion kū'ē, a me ka wela.
Hoʻohana ʻia ka pauka neodymium paʻa e hana i kēia mau magnet.Hoʻoheheʻe ʻia ka pauka a hui pū ʻia me kahi polymer.A laila kaomi ʻia nā ʻāpana a i ʻole extruded e hana i ka huahana.Hiki ke hoʻopaneʻe ʻia nā magnet Neodymium i hoʻopaʻa ʻia i nā ʻano paʻakikī me nā pou he nui.ʻOiai ʻoi aku ka nāwaliwali ma mua o Sintered Neodymium magnets, Bonded neodymium magnets e hāʻawi i ka maʻalahi i nā ʻano o nā ʻano i hiki ke hana ʻia.ʻOi aku ka māmā ma mua o Samarium Cobalt, a he haʻahaʻa haʻahaʻa haʻahaʻa (coercivity).Eia nō naʻe, hāʻawi lākou i ka waiwai maikaʻi loa no nā noi e koi ana i kahi magnet liʻiliʻi a hoʻohana paha i nā apo radial.
Noi:
Na Lako Otomo Keena, Mīkini Uila, Na Lako Leo-Kiʻi, Mea Hana, nā motika liʻiliʻi a me nā mīkini ana, nā kelepona paʻa, CD-ROM, nā motika DVD-ROM, nā motika spindle hard disk HDD, nā mīkini micro DC ʻē aʻe, a me nā mea hana automation etc.
ʻO ka wela hana kiʻekiʻe loa:
ʻOiai ʻo ka mahana Curie no ka mea NdFeB ma kahi o 310 ºC no ka 0% kobalt mea i ʻoi aku ma mua o 370 ºC no 5% kobalt, hiki ke manaʻo ʻia kekahi poho hiki ʻole ke hoʻihoʻi ʻia ma nā wela haʻahaʻa.Loaʻa i nā neo magnets kahi kiʻekiʻe kiʻekiʻe Reversible Temperature Coefficient of Induction e hōʻemi ana i ka nui o ka hoʻoiho magnetic i ka piʻi ʻana o ka mahana.ʻO ke koho ʻana i nā neo magnet ma kahi o SmCo, he hana ia o ka wela kiʻekiʻe o ka noi, koi ʻia ka hoʻokuʻu magnetic i ka mahana hana maʻamau a me ke kumukūʻai o ka ʻōnaehana.
Loaʻa i nā neo magnets kekahi mau palena ma muli o kā lākou hana corrosion.Ma ke ʻano haʻahaʻa, ʻoi aku ka maikaʻi o kahi uhi pale a i ʻole plating.ʻO nā uhi i hoʻohana maikaʻi ʻia e komo;e-coating, ka pauka, ka nickel plating, zinc plating, parylene a me nā hui pū ʻana o kēia mau uhi.
