Mea Hoʻolako Kūleʻa Kūleʻa
ʻO 304 ke kila kila kila?
Ua noʻonoʻo paha ʻoe no ke aha e pili ai kekahi mau mea kila kila i nā magnet, aʻo nā mea ʻē aʻe ʻaʻole? ʻAe, inā makemake ʻoe e pili ana i nā waiwai magnetic o ke kila kila, ua hele mai ʻoe i kahi kūpono. Ma kēia ʻatikala, e ʻimi mākou inā he magnetic a ʻaʻole paha ke kila kila 304, kekahi o nā mea hao kila kila kaulana loa. No laila, e hoʻomaka kākou a wehe i ka mea pohihihi ma hope o ka hoʻohiwahiwa magnetic o ke kila kila!
No laila, ʻo 304 ke kila kila kila?
ʻO ka pane, ʻo ka No. 304 stainless steel i manaʻo nui ʻia he non-magnetic. Eia nō naʻe, hiki ke lilo i mea hoʻokalakupua i ka wā e hana anu.
ʻO kēia ma muli o ka hoʻonohonoho hou ʻana o kāna microstructure i ka wā o ka hana anu, hiki ke hoʻolauna i nā hemahema a me nā distortions e hiki ai ke hōʻike i nā mea magnetic. Eia kekahi, hiki ke hoʻokomo ʻia ka martensite, kahi pae magnetic, i ka wā o ka hana anu. He mea liʻiliʻi kēia mau hopena a ʻaʻole pili nui i nā waiwai non-magnetic holoʻokoʻa o 304 stainless steel. Eia nō naʻe, he mea nui e ʻike i kēia hiki no ka magnetization i ka wā e hoʻohana ai i ka 304 stainless steel i nā noi kahi e hopohopo ai nā waiwai magnetic.
E hoʻomau kēia ʻatikala e kūkākūkā i kēia nīnau mai nā ʻaoʻao aʻe:

He aha ka ʻokoʻa ma waena o nā mea ferromagnetic a me nā mea non-ferromagnetic?
I ka hiki ʻana i nā mea magnetic, ʻelua mau ʻāpana ākea: ferromagnetic a me non-ferromagnetic. ʻO nā mea ferromagnetic nā mea i huki ikaika ʻia i kahi magnet a hiki ke lilo i mea magnetized mau iā lākou iho, e like me ka hao, nickel, a me ka cobalt.
ʻO nā mea non-ferromagnetic, ma ka ʻaoʻao ʻē aʻe, ua nawaliwali i ka magnet a ʻaʻole mālama i ka magnetization mau, e like me ke keleawe, aluminika, a me ke gula.
ʻO ka ʻokoʻa koʻikoʻi ma waena o nā mea ʻelua i ko lākou ʻano atomic. Loaʻa i nā mea Ferromagnetic kahi hoʻonohonoho kūʻokoʻa o nā electrons e hana i nā māla liʻiliʻi liʻiliʻi a puni kēlā me kēia atom. Hoʻonohonoho pinepine ʻia kēia mau kahua ma nā ʻaoʻao ʻokoʻa, ʻaʻole i loaʻa ke kahua magnetic holoʻokoʻa.
Eia nō naʻe, i ka wā e ʻike ʻia ai kahi mea ferromagnetic i kahi kahua magnetic o waho, ʻoi aku ka ikaika o nā pā magnetic a puni nā ʻātoma a lilo i mea ikaika, e hopena i ka magnetization.
ʻAʻole loaʻa nā mea non-ferromagnetic, ma ka ʻaoʻao ʻē aʻe, ʻaʻohe o kēia hoʻonohonoho electron kūʻokoʻa a ʻaʻole hana i nā māla magnetic ikaika a puni kēlā me kēia atom. ʻO ka hopena, ʻaʻole lākou e hōʻike i nā waiwai magnetic ikaika a ʻaʻole maʻalahi i ka magnetized.
He mea nui ka hoʻomaopopo ʻana i ka ʻokoʻa ma waena o nā mea ferromagnetic a me non-ferromagnetic i nā noi he nui, mai ka hoʻolālā ʻana i nā mea magnetic no nā mea uila a hiki i ka hoʻomaopopo ʻana i ke ʻano o nā mea i loko o nā māla magnetic. He hana koʻikoʻi nō hoʻi ia i nā mea o kēlā me kēia lā a mākou e hoʻohana ai, mai nā magnet friji a i nā kāleka hōʻaiʻē.
ʻO ke kila kila he mea hoʻohana nuiʻia i nāʻano likeʻole ma muli o kona mau waiwai maikaʻi, e like me ke kū'ēʻana i ka corrosion a me ka ikaika kiʻekiʻe. Eia nō naʻe, hiki i ka magnetism o ke kila kila ke pāʻani i kāna hana i nā noi like ʻole.
I kekahi mau noi, e like me ka ʻoihana aerospace, ʻoi aku ka maikaʻi o ke kila kila kila non-magnetic e pale aku i ka hoʻopili ʻana i nā mea hana koʻikoʻi. Ma ka ʻaoʻao ʻē aʻe, i ka ʻoihana kaʻa, hoʻohana ʻia ke kila stainless magnetic i nā ʻāpana like ʻole, e like me nā injectors wahie a me nā sensor.
Hiki i ka magnetism o ke kila kila ke hoʻopili i kona machinability. ʻOi aku ka paʻakikī o ke kila kila kila i ka mīkini ke hoʻohālikelike ʻia me ke kila kila kila ʻole, no ka mea, ʻoi aku ka maʻalahi o ka hana paʻakikī a koi i nā ʻenehana mīkini kūikawā.
Eia kekahi, hiki i ka magnetism o ke kila kila ke hoʻopili i kona weldability. Hiki i ke kila kila kila kila ke ʻike i ka puhi ʻana i ka pōā i ka wā wili, hiki ke hoʻoneʻe i ke arc a alakaʻi i nā welds maikaʻi ʻole. ʻAʻole ʻike ʻia kēia pilikia a ʻoi aku ka maʻalahi o ka welded non-magnetic stainless steel.
Ma keʻano holoʻokoʻa, hiki i ka magnetism o ke kila kila ke hana nui i kāna hana ma nā noi like ʻole. ʻO ka hoʻomaopopo ʻana i ka magnetism o ke kila kila a me ke koho ʻana i ke ʻano kūpono no nā noi kikoʻī he mea koʻikoʻi no ka hana maikaʻi a me ka lōʻihi.
Pehea ka hopena o ka magnetism o ke kila kila i kāna hana ma nā noi like ʻole?
Hiki ke hoʻololi ʻia ke kila kuhili ʻole i loko o ke kila kila kila?
ʻAe, maikaʻi, maikaʻi, hiki anei ke hoʻololi ʻia ke kila kuhili ʻole i loko o ke kila kila kila? He nīnau maikaʻi loa ia e hoʻohūhū nei i nā manaʻo hoihoi. E wawahi kakou.
ʻO ka mea mua, e wehewehe kākou ʻaʻole nā kila kuhili ʻole a pau. ʻO kaʻoiaʻiʻo, nui nā ʻano o ke kila kila ʻaʻole magnet ma muli o ko lākou ʻano aniani. Eia nō naʻe, aia kekahi mau ʻano o ke kila kila, e like me nā mea austenitic, hiki ke lilo i mea magnetic ma hope o ka hana anu.
I kēia manawa, hiki ke hoʻololi ʻia ke kila kuhili ʻole i loko o ke kila kuhili ʻole? ʻO ka pane pōkole ʻo ia, hiki. ʻO kahi ala e hana ai pēlā ʻo ia ka wehe ʻana i ke kila kila non-magnetic i kahi māla magnetic, hiki ke hoʻohālikelike i nā ʻātoma a hoʻoulu i ka magnetism. ʻIke ʻia kēia kaʻina hana magnetization.
ʻO kekahi ala ʻē aʻe, ʻo ia ka hoʻololi ʻana i ke ʻano o ke kila kila ma ka hoʻohui ʻana i nā mea e like me ka nickel a i ʻole manganese, hiki ke hoʻonui i kona mau waiwai magnetic. Eia naʻe, pili kēia i nā waiwai ʻē aʻe o ke kila kila, e like me kona kūpaʻa ʻana a me ka ikaika.
I ka hopena, ʻoiai hiki ke hoʻololi i ke kila kila kila ʻole i loko o ke kila kila kila, pono e noʻonoʻo i ka hopena o ia hoʻololi i ka hana holoʻokoʻa a me nā waiwai o ka mea. E like me nā mea he nui i ke ola, ʻo ka loaʻa ʻana o ke kaulike kūpono.
ʻO ke kila kila kila, ʻike ʻia hoʻi ʻo ka ferritic stainless steel, he ʻano hana kūpono ma muli o kāna mau waiwai magnetic.
ʻO kekahi o kāna mau noi maʻamau i ka hana ʻana i nā ʻāpana kaʻa, e like me nā ʻōnaehana exhaust, no ka mea hiki ke kū i ka corrosion a hiki ke kū i nā wela kiʻekiʻe.
Hoʻohana maʻamau ʻia ke kila kila kila ma nā mea pono hale, e like me nā pahu hau a me nā mea holoi kīʻaha, no ka lōʻihi o kona kūpaʻa a me ke kūpaʻa ʻana i ka ʻōpala a me nā stains.
ʻO kekahi noi ʻana o ke kila kila kila ma ka hana ʻana i nā mea kūkulu hale, e like me ke kaupaku a me ka ʻaoʻao, no ka mea, he kumukūʻai kūpono a me ka mālama haʻahaʻa e hiki ke kū i nā kūlana ʻino. Hoʻohui ʻia, hoʻohana pinepine ʻia i ka hana ʻana i nā mea hana ʻoihana, e like me nā pahu mālama a me nā pipelines, ma muli o kona kūʻē ʻana i nā mea corrosive.
Ma ke kahua lapaʻau, hoʻohana ʻia ke kila stainless magnetic e hana i nā mea ʻokiʻoki a me nā niho ma muli o kona kū ʻana i ka corrosion a me ka maʻalahi o ka sterilization. Hoʻohana ʻia ia i ka hana ʻana i nā meaʻai meaʻai, no ka mea, ʻaʻole ia e hoʻokō a hiki ke kū i nā wela kiʻekiʻe a me nā mea hoʻomaʻemaʻe paʻakikī.
Ma keʻano holoʻokoʻa, ʻo nā waiwai magnetic kūʻokoʻa o ke kila kila e lilo ia i mea maʻalahi a waiwai i nā ʻano ʻoihana a me nā noi.
He aha kekahi mau hoʻohana pono o ka kila kuhiliʻole magnetic?
Panina
Ua ʻimi ʻia ke kumuhana o ke kila kila kila ma ka hohonu, e uhi ana i nā nīnau e like me ka 304 stainless steel he magnetic, ka ʻokoʻa ma waena o nā mea ferromagnetic a me nā mea non-ferromagnetic, a me ka hopena o ka magnetism i ka hana o ke kila kila ma nā noi like ʻole. Ua kūkākūkā pū ʻia ka hiki ke hoʻololi i ke kila kila kila ʻole i loko o ke kila kila, me ka hoʻohana pono ʻana o ke kila kila kila.
I ka hōʻuluʻulu manaʻo, ʻoiai ʻo kekahi mau ʻano o ke kila kuhiliʻole he magnetic, ʻaʻole nā mea ʻē aʻe, a hiki i nā waiwai magnetic o ke kila kila ke hoʻopili i kona hoʻohana ʻana i nā noi like ʻole, mai ka hana ʻoihana a i nā implants biomedical. He mea koʻikoʻi ka hoʻomaopopo ʻana i kēia mau waiwai a me kā lākou mau noi no ka poʻe i ka ʻenekinia, hana, a me nā kaiāulu ʻepekema.
