Nā mea lawe nui
Hoʻopaʻa ke kila galvanized i nā waiwai ferromagnetic o kāna kumu kila kalapona; ʻAʻole pale ka zinc coating i nā māla magnetic.
Hiki i ka mānoanoa papa Zinc (ʻoi aku ka nui o nā uhi i ʻoi aku ma mua o 50 microns) hiki ke hoʻolauna i kahi āpau kino liʻiliʻi, e hōʻemi iki ana i ka manaʻo huki magnetic.
ʻO ka mānoanoa metala kumu e kuhikuhi i ka saturation magnetic; ʻO ka wehewehe ʻana i nā mea ʻoi aku ka lahilahi ke kumu o ka hāʻule ʻole ʻana o ka mīkini (dimpling) ma lalo o nā haʻahaʻa magnetic kaumaha.
ʻO ke koho ʻana ma waena o kahi ʻāpana kila galvanized a me ke kila kuhili ʻole e hilinaʻi nui ʻia i ke koena i koi ʻia o ke kumukūʻai, ka ikaika magnetic, a me ka ʻike ʻana i ke kaiapuni.
ʻO ka Mechanics: No ke aha i hoʻopaʻa ai ke kila Galvanized i ka Magnetism
ʻO ke aupuni metala kumu
ʻO ka substrate kumu e kuhikuhi i ka hana magnetic. Ma lalo o ka pale waho e noho ai ke kila kalapona. Loaʻa i ke kila kalapona kahi ʻano kristal ferromagnetic kiʻekiʻe. Hoʻopili maʻalahi nā ʻātoma hao i loko o kēia huila i ka wā e ʻike ʻia ai i kahi māla magnetic waho. Hoʻokumu kēia hoʻonohonoho wikiwiki i kahi mana hoihoi ikaika. Hiki iā ʻoe ke hilinaʻi ma luna o kēia puʻu hao paʻa e paʻa paʻa i nā haʻahaʻa magnetic kaumaha. Na ka metala kumu i nā haʻi kaumaha a pau e pili ana i ka huki ʻana.
ʻO ke kuleana o Zinc
Mālama ʻo Hot-dip galvanizing i kēia puʻu kila palupalu mai nā kaiapuni koʻikoʻi. Hoʻokomo nā mea hana i ka substrate kila maka i loko o ka ʻauʻau o ka zinc hehee. Hoʻokumu kēia kaʻina hana wela kiʻekiʻe i kahi paʻa metallurgical mau ma waena o nā metala. ʻO ka hopena zinc layer e hana ma ke ʻano he anode mōhai. ʻOi aku ka maikaʻi o ka oxidize i ka wā e ʻike ʻia i ka makū. Ma ka kaumaha ʻana iā ia iho, pale ka zinc i ka ʻeleʻele ʻulaʻula luku mai ka hoʻouka ʻana i ka hao ma lalo.
ʻO ka ʻoiaʻiʻo ʻo 'Paʻi
ʻO ka zinc maʻemaʻe he diamagnetic loa. ʻAʻole loaʻa iā ia nā waiwai magnetic. Manaʻo ka nui o nā poʻe i kēia panina non-magnetic blocks magnetism holoʻokoʻa. ʻO ia ka hoʻomaopopo piha ʻana o ka physics pili. Hōʻike ʻia nā ʻāpana zinc maʻamau i ka mānoanoa microscopic. ʻAʻole lākou e hoʻopau wale i ke kahua magnetic i hana ʻia e ke kumu kila. Hiki ke komo maʻalahi ke kahua magnetic i ʻike ʻole ʻia i ka pale zinc lahilahi. Loaʻa iā ʻoe kahi paʻa paʻa a hilinaʻi.
ʻOiaʻiʻo ʻenekinia: Pehea ka pili ʻana o ka uhi a me ka mānoanoa o nā mea i ka huki ʻana i ka Magnetic
Ka mānoanoa o ka uhi ʻana (The Gap Effect)
Hoʻopili ka Magnetism i ke kānāwai square square. Ke piʻi aʻe ka mamao ma waena o ka magnet a me ka metala, hāʻule nui ka ikaika hoihoi. E noʻonoʻo i ka galvanization mānoanoa ma ke ʻano he spacer kino. ʻO nā uhi i ʻoi aku ma mua o 50 microns e hoʻokuke iki i ka magnet mai ke kumu kila ikaika. ʻAʻole hoʻopau ka zinc i ka magnetism. Eia nō naʻe, hoʻonāwaliwali iki kēia ʻāpana kino microscopic i ka huki ʻana o ka ʻili. Pono nā ʻenekinia e helu i kēia āpau i ka helu ʻana i nā ikaika huki pono.
Mānoanoa o ka lepo (Satation Magnetic)
Hoʻokomo ka mānoanoa mea i kahi pilikia hoʻokō koʻikoʻi. Pono nā mākēneki i ka nui o ka hao no ka hoʻokō ʻana i ka ikaika pipili piha. Kāhea ka poʻe ʻoihana ʻoihana i kēia paepae magnetic saturation. ʻO ka wehewehe ʻana i kahi metala lahilahi ʻoi aku ka liʻiliʻi i nā ala magnetic i loaʻa. ʻAʻole hiki i ka magnet ke hoʻopaʻa i kona hiki. Inā hoʻopiha ke kila ma mua o ka hiki ʻana o ka magnet i kona ikaika huki piha, e paheʻe a hāʻule paha ka mea paʻa.
Ka Pilikia Dimpling
Pono nā puʻu māneʻe koʻikoʻi i ka nui kila e hana pono ai. ʻO ke kau ʻana i nā mea hana koʻikoʻi a i ʻole nā mea hōʻike ma luna o nā metala ultra-thin e alakaʻi i nā pilikia koʻikoʻi. Hoʻokumu ka paona kūloko i ka torque kiʻekiʻe ma ke kiko kau. Hoʻomaka koke ka metala i ka warping. ʻAʻole koke, ʻike ʻoe i ka dimpling ʻike ʻia a puni ka mea hoʻopaʻa magnetic.
No ka pale ʻana i ka deformation mechanical, e makaʻala i kēia mau hewa ʻenehana maʻamau:
Ke hoʻohana ʻana i nā mea hoʻokalakupua o ka honua i nā paneli hoʻonaninani.
Ke nānā ʻole nei i ka leverage i hana ʻia e nā bracket shelving cantilevered.
ʻAʻole hāʻawi i ke kākoʻo paʻa ma hope o nā papa magnetic palahalaha.
Manaʻo Kūmole
Pono ʻoe i ka nuipa kūpono e pale ai i kēia mau hemahema mechanical. Paipai mākou i ke kila haʻahaʻa haʻahaʻa 16-gauge e like me kāu kikoʻī kumu. Aia kēia ana ma kahi o 1.5mm ka mānoanoa. Hāʻawi ia i ka saturation magnetic maikaʻi loa no nā magnet kalepa. He kūpono loa ia i nā papa magnetic structural, RV mobile applications, a me nā paneli pā hale hana kaumaha.
Ka Loiloi Mea: Galvanized Steel vs. Alternative Magnetic Metals
ʻO ke kila kila kūʻē
ʻO nā microstructure metala ke kuhikuhi i ka hana magnetic. Maikaʻi mau nā mea Galvanized no ka mea ʻaʻole i loli ke kumu. Hōʻike ke kila kila i kahi ʻoiaʻiʻo paʻakikī loa. Pili loa kona magnetism i kona pae metallurgical.
Hōʻike nā kila kuhili ʻole Ferritic a me martensitic i nā waiwai magnetic ikaika. Eia nō naʻe, ʻaʻole magnetik nā kila kuhili ʻole austenitic (e like me nā māka kaulana 304 a me 316). ʻO ka hoʻohui ʻana i ka nui o ka nickel i ka wā o ke kaʻina hoʻohuihui e hoʻopau i ka hiki ke kahua magnetic. Kūpaʻa maoli ke kila kila Austenitic i ka ʻino me ka ʻole o ka papa zinc waho. Hāʻawi ia i ka maʻemaʻe kūikawā no nā lumi maʻemaʻe. Akā naʻe, ʻaʻole hiki iā ia ke kākoʻo i nā mea hana magnetic. Hoʻohana pinepine nā halemaʻi i ka stainless austenitic no kēia kumu, ʻoi aku ka nui ma kahi o ka lumi MRI kahi i hoʻopilikia ʻia ai nā ulia pōpilikia.
ʻO ka hao hao me ka Aluminum
Hāʻawi ka Aluminum i ke kūpaʻa ʻino maikaʻi loa a he liʻiliʻi loa ke kaumaha. Eia naʻe, ʻaʻole loa ka alumini. Loaʻa iā ia nā ʻātoma hao e pono ai e launa pū me kahi māla magnetic. ʻAʻole kūpono kēia i ka alumini no nā noi hoʻopili magnetic. ʻOiai e ulu ana nā metala ʻelua i ka wā ʻino, ʻo ke koho kila wale nō ke kākoʻo i nā ʻōnaehana hoʻopili magnetic.
