Ke kūʻai nei i nā Magnets? Eia ke kamaʻilio pololei āu e pono ai

He Luʻu Hohonu i ka Honua o nā Mākēneki Mau

Inā ʻoe e ʻimi nei i nā mea magnet no kahi papahana, ua ʻike paha ʻoe iā ʻoe iho i hoʻopiha ʻia e nā kikoʻī loea a me nā wahi kūʻai nani. Hoʻolei ʻia nā huaʻōlelo e like me "N52" a me "pull force" i kēlā me kēia manawa, akā he aha ka mea nui i ka wā e pili ana i ka noi honua maoli? E hoʻokuʻu i ka fluff a iho i ka ʻoihana. ʻAʻole kēia he manaʻo puke haʻawina wale nō; ʻo ia ka ʻike paʻakikī i loaʻa mai nā makahiki he nui o ke koho ʻana i nā mea magnet no nā hana ma luna o ka honua, me ka nānā ʻana i ka workhorse āu e loaʻa maoli ai no ka hapa nui: ka neodymium bar magnet.

ʻO ka Lineup Magnet - Ke koho ʻana i kāu hui

E noʻonoʻo i nā magnet mau loa e like me nā ʻano mea kūkulu hale ʻokoʻa - aia kēlā me kēia mea i ka hoʻohana ponoʻī ʻana, a ʻo ke koho ʻana i ka mea hewa he ala ʻoiaʻiʻo ia e hoʻopau i kāu papahana.

Mākēneki Ceramic (Ferrite):ʻO ke kuamoʻo hilinaʻi a maikaʻi hoʻi o ka honua magnet. E ʻike ʻoe iā lākou ma ke ʻano he mau ʻeleʻele i loko o nā mea haʻi'ōlelo o kāu kaʻa a i ʻole e paʻa ana i kāu keʻena hale hana. ʻO kā lākou pōmaikaʻi nui loa? ʻAʻole paʻa lākou i ka ʻino a hiki ke paʻi kino. ʻO ke kālepa-off? Ua lawa ko lākou ikaika magnetic, ʻaʻole kupanaha. E hoʻohana iā lākou inā paʻa ka waihona kālā a ʻaʻole pono ʻoe i ka mana paʻa kaumaha.

Alnico Magnets:ʻO ke koho maʻamau. Hoʻopili ʻia mai ka aluminika, nickel, a me ka cobalt, ʻo lākou ka mea e hele ai no ke kūpaʻa kiʻekiʻe-ma muli o ko lākou hele ʻana i nā mea kani kahiko, nā kiʻi kīkā premium, a me nā mea ʻike kokoke i nā mīkini. Akā, he nāwaliwali ko lākou: hiki i ka jolt paʻakikī a i ʻole ke kahua kuʻekuʻe kūʻē ke wehe iā lākou i kā lākou magnetism. ʻOi aku ka maikaʻi ma mua o nā magnet seramika, e hoʻolilo iā lākou i koho niche.

Nā Mākēneki Samarium Cobalt (SmCo):ʻO ka loea no ka hana koʻikoʻi. Makemake ʻoe i kahi magnet e hoʻomāʻewaʻewa ana i ka wela 300°C a i ʻole ka ʻike ʻana i nā kemika? ʻO ia kēia. ʻO nā ʻoihana Aerospace a me nā ʻoihana pale e uku i ka uku no ko lākou kūpaʻa ʻole, akā no ka 95% o nā hana ʻoihana, ʻoi aku lākou.

Nā Mākēneki Neodymium (NdFeB):ʻO ka poʻokela ikaika ʻole. ʻO ia ke kumu i emi ai kā mākou mea uila a ua ʻoi aku ka ikaika o nā mea hana ʻenehana - e noʻonoʻo i ka magnet liʻiliʻi akā ikaika i kāu drill cordless. Makaʻala koʻikoʻi: ʻO kēia mau mea magnet e maʻalahi loa i ka ʻōpala. ʻO ka haʻalele ʻana i kahi mea i uhi ʻole ʻia e like me ka waiho ʻana i kahi pahu kila i ka ua; ʻAʻole koho ka hoʻopau pale - he mea pono ke ola.

Nā Specs Decoded - Aia ka Diabolo i nā kikoʻī

Eia pehea e heluhelu ai i kahi pepa kikoʻī e like me ka pro i aʻo ʻia mai nā kuhi hewa.

Ka Pahele Papa (N-helu):ʻOiaʻiʻo, ʻoi aku ka ikaika o ka helu N kiʻekiʻe (e like me N52) ma mua o ka helu haʻahaʻa (N42). Akā, eia kahi mea huna: ʻoi aku ka palupalu o nā māka kiʻekiʻe. Ua ʻike au i ka haki ʻana o nā magnet N52 ma lalo o kahi haʻalulu e paʻi ʻia kahi N42 me ka ʻole o kahi ʻōpala. ʻO ka pinepine ma mua o ka ʻole, ʻoi aku ka nui o ka magnet N42 ʻoi aku ka naʻauao, ʻoi aku ka paʻa - loaʻa iā ʻoe ka ikaika huki like me ka ʻole o ka palupalu.

Huki ikaika:ʻO ka Lab Fairy Tale vs. Shop Floor Reality: ʻO kēlā maka-popping ka helu ikaika ma ka pepa kikoʻī? Ua ana ʻia ma luna o kahi poloka kila mānoanoa, mānoanoa, aniani i loko o kahi keʻena hoʻomalu ea. ʻO kāu noi? He kaola I pena ʻia, ʻaʻa iki i uhi ʻia i ka unahi wili. Ma ka honua maoli, hiki i ka mana paʻa maoli ke lilo i ka hapalua o ka mea i koi ʻia e ka catalog. Ka lula: E hoʻohana i nā kikoʻī no ka hoʻohālikelike, akā hilinaʻi wale i kahi prototype i hoʻāʻo ʻia ma kāu ʻili maoli.

Palena wela:Noho Kiʻekiʻe ʻO Coercivity: ʻO ka Coercivity ka "mana mau" o ka magnet—ʻo ia ka mea e pale ai i ka nalowale ʻana o ka magnetism ke ʻike ʻia i ka wela a i waho paha o nā māla magnetic. Inā kokoke kāu magnet i kahi kaʻa, ma kahi wili, a i ʻole ma luna o ka hale metala i kālua ʻia e ka lā, pono ʻoe e koho i kahi māka wela kiʻekiʻe (e makaʻala i nā suffix e like me 'H', 'SH', a i ʻole 'UH'). Hoʻomaka ka pōʻino mau loa o nā magnet neodymium maʻamau ke piʻi ka mahana ma luna o 80°C (176°F).

Ke koho ʻana i ka uhi kūpono - ʻo ia ka mea kaua:

Nikela (Ni-Cu-Ni):ʻO ka hoʻopau maʻamau. He ʻālohilohi, kūʻai kūʻai, a maikaʻi loa no ka hoʻohana ʻana i loko o ka hale—e noʻonoʻo i nā hui huahana a i ʻole nā ​​lumi hoʻomaʻemaʻe.

Epoxy/Polymer uhi:ʻO ke kanaka paʻakikī o ka uhi. He papa matte, waihoʻoluʻu pinepine e kūʻē i ka ʻoki ʻana, nā mea hoʻoheheʻe, a me ka maʻu ma mua o ka nickel. No nā mea i hoʻohana ʻia ma waho, i loko o kahi hale kūʻai mīkini, a i ʻole kokoke i nā kemika, ʻo ka epoxy wale nō ke koho kūpono. E like me ka ʻōlelo a ka mea kahiko i loko o kahi hale kūʻai: "Maikaʻi nā mea ʻālohilohi i loko o ka pahu. Ke hana mau nei nā mea i uhi ʻia epoxy i nā makahiki ma hope."

No ke aha i lilo ai ka Bar Magnet i kou hoa aloha

Loaʻa ka hoʻohana ʻana i nā disc a me nā apo, akā ʻo ka haʻahaʻaneodymium bar magnetʻO ia ka hale kūkulu hope loa no nā hana ʻenehana a me DIY. Hāʻawi kona ʻano ʻāpana ʻehā i kahi alo magnetic lōʻihi a paʻa-kūpono no ka mana paʻa paʻa like ʻole.

Kahi e loaʻa ai kāna mālama:Hana ʻia kona geometry no nā hana maʻamau. E laina iā lākou e hana i ka pahu sweeper magnetic no ka ʻohi ʻana i nā ʻōpala metala. E hoʻokomo iā lākou i loko o kahi paʻa alumini maʻamau e paʻa i nā ʻāpana i ka wā wili. E hoʻohana iā lākou e like me nā mea hoʻoulu i nā mea ʻike kokoke. ʻO ko lākou mau ʻaoʻao pololei e ʻae iā ʻoe e kūkulu i nā ʻāpana magnetic ikaika no ka hāpai a paʻa ʻana i nā ukana kaumaha.

ʻO ka kikoʻī o ke kauoha nui a nā mea a pau i hala:Ke kauoha ʻana i nā ʻāpana 5,000, ʻaʻole hiki iā ʻoe ke ʻōlelo wale i ka "2-inch bar." Pono ʻoe e hōʻike i ka ʻae ʻana o ka nui (e laʻa, 50.0mm ±0.1mm). ʻAʻole e komo ka pūʻulu o nā magnet like ʻole i kāu mau mīkini mīkini, a hiki ke hōʻino i kahi hui holoʻokoʻa. Na nā mea hoʻolako kaulana e ana a hōʻoia i kēia mau ʻae ʻana-ʻaʻole e hoʻoholo i ka liʻiliʻi.

Palekana: Non-Negotiable:

         ʻO ke kuʻi ʻana/pilikia:Hiki i nā mākēneki neodymium nui ke paʻi pū me ka ikaika e wāwahi i nā iwi. E mālama mau iā lākou pākahi a me ka akahele loa.

         Pilikia Poino Electronic:Hiki i kēia mau magnet ke hoʻopau loa i nā kāleka hōʻaiʻē, nā paʻakikī paʻakikī, a me nā media magnetic ʻē aʻe. ʻO ka mea hou aku, hiki iā lākou ke hoʻopau i ka hana pacemaker mai kahi mamao mamao loa.

         Nā Kūlana Kūlana:E mālama i nā magnet neodymium ma ke ʻano e pale aku ai iā lākou mai ka hoʻopā ʻana i kekahi i kekahi - ʻo nā mea hoʻokaʻawale pahu pahu a i ʻole nā ​​​​kau ​​hoʻokahi e hana maikaʻi loa no kēia.

         Welding Safety Alert:He lula hiki ʻole ke kūʻai ʻia kēia: Mai hoʻohana i kahi magnet neodymium ma kahi kokoke i kahi arc wili ikaika. Hiki i ke kahua magnetic ke hoʻouna aku i ke arc e lele ana ma nā ʻaoʻao ikaika, ʻike ʻole ʻia, e kau ana i ka welder i kahi pōʻino koʻikoʻi.

Ke hana pū me kahi mea hoʻolako - He Paahana

ʻAʻole wale kāu pahuhopu e kūʻai i nā magnet; ʻo ka hoʻoponopono ʻana i kahi pilikia. E mālama i kāu mea hoʻolako ma ke ʻano he hoa hana ma ia kaʻina hana. E kaʻana like i nā kikoʻī koʻikoʻi o kāu pāhana: "E hoʻopaʻa ʻia kēia i kahi pahu forklift, uhi ʻia i ka wai hydraulic, a hana mai -10°C a 50°C."

Na ka mea hoʻolako maikaʻi e nīnau i nā nīnau hahai e hoʻomaopopo i kāu mau pono. E hoʻihoʻi ka mea maikaʻi inā hana hewa ʻoe: "Ua noi ʻoe iā N52, akā no kēlā ukana haʻalulu, e kamaʻilio e pili ana iā N42 me kahi kapa epoxy mānoanoa." A i nā manawa a pau-e kiʻi mua i nā laʻana kino. E hoʻokomo iā lākou ma o ka wringer i loko o kou kaiapuni ponoʻī: e hoʻoinu iā lākou i loko o ka wai, e hōʻike iā lākou i nā wela wela, e hoʻāʻo iā lākou a hiki i ka pau ʻana. ʻO kēlā mau haneli kālā i hoʻohana ʻia ma nā prototypes ʻo ia ka ʻinikua liʻiliʻi loa āu e kūʻai ai no kahi pōʻino hana ʻelima.

Ke laina lalo: Ma ka nānā ʻana i nā kikoʻī kikoʻī o ka laina kiʻekiʻe a me ka nānā ʻana i ka lōʻihi pono, pololei, a me ka hui pū ʻana me kāu mea hoʻolako, e hoʻohana ʻoe i ka mana piha o nā magnets — ʻoi aku ka nui o ka neodymium bar magnet — e kūkulu i nā hopena ʻaʻole ikaika wale nō, akā hilinaʻi a palekana no nā makahiki e hiki mai ana.

Makemake ʻoe iaʻu e hoʻohui i kahi ʻāpana ma nā hae ʻulaʻula e pale aku i ke koho ʻana i kahi mea hoʻolako magnet e hoʻonui i ka ʻatikala no kāu poʻe heluhelu?
