He metala maʻemaʻe a hoʻokahi ke keleawe, ʻo kēlā me kēia mea i hana ʻia me ke keleawe e hōʻike i nā waiwai like.Ma ka ʻaoʻao ʻē aʻe, ʻo ke keleawe he ʻāpana keleawe, zinc, a me nā metala ʻē aʻe.ʻO ka hui pū ʻana o kekahi mau metala, ʻaʻohe ala lapuwale e ʻike ai i nā keleawe āpau.Eia naʻe, e kamaʻilio mākou e pili ana i ke ʻano o ka hoʻokaʻawale ʻana i ke keleawe mai ke keleawe.Hōʻike ʻia kēia mau ʻano ma lalo nei:
● ʻIke kala
E hoʻomaʻemaʻe i nā metala ʻelua e hoʻokaʻawale ʻia.Hoʻokumu nā keleawe a me ke keleawe i kahi patina me ka manawa.He ʻōmaʻomaʻo ka nui o kēia patina.Ma kahi e ʻike ʻia ai ka metala mua, e hoʻāʻo i ka ʻenehana hoʻomaʻemaʻe keleawe.ʻOiai e hana ana kēia ʻenehana no nā metala ʻelua, e hoʻohana i nā huahana hoʻomaʻemaʻe keleawe a me ke keleawe ma ka ʻaoʻao palekana.
E kau i ka metala ma lalo o ke kukui keʻokeʻo.Ma keia hihia, ina ua poni ia na metala i ikeia, alaila, ikeia ke kukui hoopunipuni ma muli o ka malamalama o ka malamalama.ʻO kekahi ala ʻē aʻe e hele ai a puni kēia, ʻo ia ka nānā ʻana ma lalo o kahi ʻōpuʻu kukui keʻokeʻo a i ʻole ka lā.No ka ʻike ʻana, e ʻoluʻolu e pale i ka ʻōpuʻu kukui melemele.
E ʻike i ke kala ʻulaʻula o ke keleawe.He metala maʻemaʻe me ke ʻano ʻulaʻula ʻulaʻula.
E nānā i ke keleawe melemele.Hana ʻia ke keleawe me ke keleawe a me ka zinc.ʻO ka ʻokoʻa like ʻole o ka zinc ma ke keleawe e hana i nā kala like ʻole.ʻO ka hapa nui, ʻo ke keleawe maʻamau i hoʻohana ʻia e hōʻike i ka waihoʻoluʻu melemele a i ʻole ke ʻano melemele-ʻeleʻele e like me ke keleawe.ʻO kekahi ʻano keleawe he ʻōmaʻomaʻo-melemele i ka nānā ʻana, ʻoiai ua kapa ʻia kēia hui ʻo "ka gilding metal".Loaʻa iā ia nā noi liʻiliʻi i nā mea kaua a me nā mea hoʻonaninani.
E nānā no ke keleawe ʻulaʻula a ʻalani paha.Ke haku ʻia ka metala keleawe he 85% keleawe ma ka liʻiliʻi loa, ʻulaʻula a ʻalani paha ke nānā aku.Hoʻohana nui ʻia kēia ʻano keleawe i nā mea paʻa hoʻonaninani, nā mea nani, a me nā paipu.No laila, ʻo kēlā me kēia hōʻailona o ka melemele, ʻalani, a i ʻole ke kala gula e hōʻike ana i ke keleawe he keleawe a ʻaʻole keleawe.
Ke ʻike ʻana i nā keleawe ʻē aʻe.Hiki ke nānā aku i ke gula ʻōmaʻomaʻo, keʻokeʻo, hina, a i ʻole melemele-keʻokeʻo.ʻAʻole maʻamau nā ʻāpana o kēia mau ʻāpana no ka mea ʻaʻole hiki ke machinable.Eia naʻe, hiki iā ʻoe ke ʻike i kā lākou noi i nā mea nani.
● Nā ʻano ʻē aʻe o ka ʻike
Ka hoʻohana ʻana i ke kani: no ka mea, he metala palupalu ke keleawe, hoʻopuka ʻo ia i kahi leo pōʻai pōʻai i ka wā e paʻi ana i kahi mea ʻē aʻe.Ua hōʻike ʻia kahi hoʻāʻo i ka makahiki 1987 i ke kani keleawe he 'make' aʻo ke keleawe i ʻōlelo ʻia e hoʻopuka i kahi leka kani.He paʻakikī paha ka hoʻoholo ʻana me kēia ʻano me ka ʻike ʻole.ʻO ka nūhou maikaʻi, ʻo ke aʻo ʻana i kēia ʻano hana i ka wā lōʻihi he mea pono loa ia no kahi ʻoliʻoli ʻohi kahiko a ʻōpala paha.ʻOi aku ka maikaʻi o kēia ʻano hana no kahi ala paʻa.
Ke koho ʻana i ka metala kūpono no kāu papahana
ʻO ke koho ʻana i ke ʻano metala kūpono no kahi noi he mea koʻikoʻi ia e nānā i ka wā e pili ana i ka hoʻolālā ʻana a me ka hana ʻana i nā huahana kiʻekiʻe a i ʻole nā ʻāpana.ʻOiai nā metala ʻelua (Copper & Brass) hāʻawi i ka thermal a me ka uila conductivity, ka ikaika, ka pale ʻana i ka corrosion, a me nā mea hou aʻe, loaʻa iā lākou nā ʻokoʻa like ʻole.
ʻOiai lōʻihi kēlā me kēia keleawe a me ke keleawe, ʻaʻole like ka pae o ka maʻalahi.Ma ke koho ʻana no kāu papahana, ʻo ke keleawe oxygen-free maʻemaʻe e hōʻike i ka maʻalahi, conductivity, a me ka ductility ʻoiai ke hāʻawi nei ke keleawe i ka machinability.
Ma ke ʻano o ka pono maʻamau, ʻike nui ʻia ke keleawe a kūpono loa no nā noi maʻamau.He maʻalahi ke hoʻolei ʻana, ʻano kūʻai ʻole, a malleable me ka haʻahaʻa haʻahaʻa.ʻOi aku ka maikaʻi o ke keleawe no nā mea hoʻonaninani a me nā ʻāpana metala i hui ʻia e ka poʻe i kēlā me kēia lā e like me ka puka puka.Hoʻohana ʻia ia i ka ʻoihana hana meaʻai no nā māka meaʻai e pono e pale ʻia mai ka microbial a me ka infestation bacteria.
Hōʻuluʻulu manaʻo: Brass vs. Copper, ʻO wai ka mea maikaʻi loa no kāu papahana?
He mea koʻikoʻi ka hoʻomaopopo ʻana i nā waiwai o ke keleawe a me ke keleawe i ke koho ʻana i nā mea maikaʻi loa no kāu mau papahana.Kōkua ia i ka hāʻawi ʻana i nā pane i ka nīnau kahiko o "ʻo wai ka maikaʻi ma waena o ke keleawe a me ke keleawe."ʻO kā mākou ʻike kikoʻī e hoʻomaopopo iā ʻoe he ʻoi aku ka waiwai o nā metala ʻelua i kā lākou noi.I ka hopena, ʻoi aku ka maikaʻi o nā metala ʻelua no kā lākou noi kikoʻī.
Inā makemake ʻoe i ka hana ʻana i nā ʻāpana keleawe a i ʻole nā mea keleawe machining, ʻo JINDALAI ka mea hoʻolako maikaʻi loa hiki iā ʻoe ke hilinaʻi, hauʻoli wau i ka lohe ʻana mai iā ʻoe!
