I kēia manawa, ʻo nā mea magnetic mau loa he ferrite magnet,NdFeb magnet, SmCo magnet, Alnico magnet, mea hao hao a pela aku.He mea maʻalahi kēia e kūʻai, me ka hana maʻamau (ʻaʻole pono nā kūlana ISO) e koho mai.Loaʻa i kēlā me kēia o nā magnet i luna kona mau hiʻohiʻona ponoʻī a me nā kahua noi like ʻole, ʻo ka mea i hōʻike pōkole ʻia penei.
Neodymium magnet
ʻO NdFeb kahi magnet i hoʻohana nui ʻia a ulu wikiwiki.
Hoʻohana nui ʻia ka neodymium magnet mai ka mea hou a hiki i kēia manawa, akā ʻoi aku ma mua o 20 mau makahiki.Ma muli o kona mau waiwai magnetic kiʻekiʻe a me ka hana maʻalahi, a ʻaʻole kiʻekiʻe loa ke kumukūʻai, no laila ke hoʻonui wikiwiki nei ke kahua noi.I kēia manawa, ʻo ka NdFeb pāʻoihana, hiki i kāna huahana ikehu magnetic ke hiki i 50MGOe, a he 10 mau manawa o ka ferrite.
ʻO NdFeb kekahi huahana metallurgy pauka a ua hana ʻia ma ke ʻano like me ka samarium cobalt magnet.
I kēia manawa, ʻo ka mahana hana kiʻekiʻe o NdFeb ma kahi o 180 degere Celsius.No nā noi koʻikoʻi, ʻōlelo pinepine ʻia ʻaʻole ma mua o 140 degere Celsius.
Hiki ke ʻino ʻia ʻo NdFeb.No laila, ʻo ka hapa nui o nā huahana i hoʻopau ʻia e electroplated a i uhi ʻia.ʻO ka hoʻomaʻamaʻa maʻamau ma luna o ka nickel plating (nickel-copper nickel), zinc plating, alumini plating, electrophoresis, a me nā mea ʻē aʻe.
Ma muli o nā waiwai magnetic kiʻekiʻe o NdFeb, i nā manawa he nui, hoʻohana ʻia e hoʻololi i nā mea magnetic ʻē aʻe e hōʻemi i ka nui o nā huahana.Inā hoʻohana ʻoe i nā magnet ferrite, ka nui o ke kelepona paʻa i kēia manawa, makaʻu wau ʻaʻole i emi iho ma mua o ka hapalua o ka pōhaku.
ʻOi aku ka maikaʻi o ka hana ʻana o nā magnet ʻelua ma luna.No laila, ʻoi aku ka maikaʻi o ka hoʻomanawanui ʻana o ka huahana ma mua o ka ferrite.No nā huahana maʻamau, hiki ke hoʻomanawanui (+/-) 0.05mm.
Samarium Cobalt magnet
ʻO ka Samarium cobalt magnets, nā mea nui he samarium a me ka cobalt.Ma muli o ke kumukūʻai o nā mea waiwai, ʻo samarium cobalt magnets kekahi o nā ʻano pipiʻi loa.
ʻO ka huahana ikehu o ka samarium cobalt magnets hiki i kēia manawa ke hiki i 30MGOe a i ʻole ke kiʻekiʻe.Eia kekahi, ʻo ka samarium cobalt magnets he mea koʻikoʻi a pale i ka wela kiʻekiʻe, a hiki ke hoʻohana ʻia i nā mahana a hiki i 350 degere Celsius.No laila ʻaʻole hiki ke hoʻololi ʻia i nā noi he nui
No nā huahana metallurgy pauka ka Samarium cobalt magnet.ʻO nā mea hana maʻamau e like me ka nui a me ke ʻano o ka huahana i hoʻopau ʻia e pono ai, puhi ʻia i kahi blank square, a laila hoʻohana i ka pahi daimana e ʻoki i ka nui o ka huahana i hoʻopau ʻia.Ma muli o ka hoʻokele uila ʻo samarium cobalt, hiki ke ʻoki ʻia i ka laina laina.ʻO ka manaʻo, hiki ke ʻoki ʻia ka samarium cobalt i kahi ʻano hiki ke ʻoki ʻia i ka laina laina, inā ʻaʻole manaʻo ʻia ka magnetization a me ka nui nui.
Loaʻa i ka Samarium cobalt magnets maikaʻi loa ka pale ʻana i ka corrosion a maʻamau ʻaʻole koi i ka pale anti-corrosion a i ʻole ka uhi.Eia kekahi, he palupalu nā samarium cobalt magnets, paʻakikī ke hana i nā huahana i nā liʻiliʻi liʻiliʻi a i ʻole nā paia lahilahi.
Alnico magnet
Loaʻa iā Alnico magnet ka hoʻolei ʻana a me ka sintering i ʻelua ʻano hana like ʻole.ʻOi aku ka hoʻolei ʻana o Alnico i nā huahana kūloko.ʻO ka huahana ikehu o Alnico magnet hiki ke piʻi i ka 9MGOe, a he hiʻohiʻona nui ʻo ia ka pale wela kiʻekiʻe, hiki i ka mahana hana ke hiki i 550 degere Celsius.Eia nō naʻe, maʻalahi loa ka Alnico magnet i ka demagnetize i loko o kahi kahua magnetic inverted.Inā ʻoe e hoʻokuʻi i ʻelua mau pou magnet Alnico i ka ʻaoʻao like (ʻelua N a ʻelua paha S) i hui pū ʻia, e hoʻihoʻi ʻia a hoʻohuli ʻia paha ke kahua o kekahi o nā mea magnet.No laila, ʻaʻole kūpono ia no ka hana ʻana i loko o ke kahua magnetic inverted (e like me ke kaʻa).
He kiʻekiʻe ka paʻakikī o Alnico a hiki ke ʻoki ʻia a ʻoki ʻia i ka uea, akā ma ke kumukūʻai kiʻekiʻe.ʻO ka lako maʻamau o nā huahana i hoʻopau ʻia, ʻelua ʻano o ka wili maikaʻi a i ʻole ka wili ʻole.
Mākēneki Ferrite / Mākēneki Seramika
ʻO Ferrite kahi ʻano mea ʻano mea hoʻokalakupua nonmetallic, i ʻike ʻia hoʻi ʻo nā ceramics magnetic.Lawe mākou i kahi lekiō maʻamau, a ʻo ka horn magnet i loko he ferrite.
ʻAʻole kiʻekiʻe nā waiwai magnetic o ka ferrite, ʻo ka huahana ikehu magnetic o kēia manawa (kekahi o nā ʻāpana e ana i ka hana o kahi magnet) hiki ke hana i 4MGOe kiʻekiʻe iki.Loaʻa i ka mea waiwai ka pōmaikaʻi nui o ke kumukūʻai.I kēia manawa, hoʻohana nui ʻia ia ma nā ʻano he nui
ʻO Ferrite ka keramika.No laila, ua like ka hana machining me nā seramika.Hoʻokumu ʻia nā magnet Ferrite, hoʻoheheʻe ʻia.Inā pono e hana, hiki ke hana i ka wili maʻalahi.
Ma muli o ka paʻakikī o ka hana mechanical, no laila he maʻalahi ka hapa nui o ke ʻano o ka ferrite, a ʻoi aku ka nui o ka hoʻomanawanui.He maikaʻi nā huahana ʻano square, hiki ke wili ʻia.Poʻai, wili wale i ʻelua mau mokulele.Hāʻawi ʻia nā ʻae ʻokoʻa ʻē aʻe ma ke ʻano he pākēneka o nā ana nominal.
Ma muli o ka hoʻohana ʻia ʻana o ka magnet ferrite no nā makahiki he nui, nui nā mea hana i hoʻomākaukau i nā apo, nā ʻāpana a me nā huahana ʻē aʻe o nā ʻano maʻamau a me nā nui e koho ai.
No ka mea ʻo ka ferrite ka mea seramika, ʻaʻohe pilikia corrosion.ʻAʻole pono nā huahana i hoʻopau ʻia i ka mālama ʻana a i ʻole ka uhi ʻana e like me ka electroplating.
