I kekahi manawa i kapa ʻia ʻo 'metala ʻulaʻula', keleawe, keleawe a me ke keleawe hiki ke paʻakikī ke wehewehe. E like me ka waihoʻoluʻu a kūʻai pinepine ʻia i nā ʻāpana like, kahaha paha ka ʻokoʻa o kēia mau metala! E ʻoluʻolu e ʻike i kā mākou papa hoʻohālikelike ma lalo nei e hāʻawi iā ʻoe i kahi manaʻo:
| kalakala | Nā noi maʻamau | Nā pōmaikaʻi | |
| keleawe | ʻulaʻula ʻalani | ● Paipu & paipu ● Uea | ● Kiʻekiʻe uila & thermal conductivity ● Hoʻopili maʻalahi a ductile loa ● ʻO nā waiwai antibacterial maikaʻi |
| keleawe | Hiki ke loaʻa mai ka ʻulaʻula a i ke kala gula ma muli o ke kiʻekiʻe o ka zinc i hoʻohui ʻia i ka alloy | ● Nā mea kāhiko ● Nā mea kani | ● Hiki ke kala like me ke gula ● Maikaʻi ka hana a me ka lōʻihi ● ʻO ka ikaika maikaʻi loa, me ka nui o ka zinc 39%. |
| keleawe | ʻO ke gula ʻulaʻula | ● Nā mekala a me nā makana ● Nā kiʻi kiʻi ● ʻOihana a me nā bearings | ● Paʻa i ka corrosion ● ʻOi aku ka wela a me ka conductivity uila ma mua o ka nui o nā kila. |
1. He aha ke keleawe?
ʻO ke keleawe kekahi mea metala i loaʻa ma ka papaʻaina. He kumuwaiwai kūlohelohe ia i loaʻa ma ka honua a he mea hoʻohui i ke keleawe a me ke keleawe. Lawe nā mines keleawe i ke keleawe maka mai ka ili o ka honua a hiki ke loaʻa ma ka honua holoʻokoʻa. No ka mea, he conductive nui kēia metala a hiki ke kū i ka wela, hoʻohana pinepine ʻia i nā ʻōnaehana uila a me nā kamepiula. Hoʻohana pinepine ʻia nā paipu keleawe i ka paipu. ʻO kekahi o nā mea maʻamau i hana ʻia mai ke keleawe i hana hou ʻia ma nā pā pā, ʻo ia ka uea keleawe, ke kaula, a me nā paipu. ʻO ke keleawe kekahi o nā metala kiʻekiʻe loa ma nā pā ʻōpala.
2. He aha ke keleawe?
ʻO ke keleawe he mea hoʻoheheʻe metala, ʻo ia hoʻi he metala i hana ʻia me nā mea he nui. He hui ia o ke keleawe a me ka zinc, a i kekahi manawa ka tin. Hiki i nā ʻokoʻa o ka pākēneka o ke keleawe a me ka zinc ke hoʻololi i ke kala a me nā waiwai o ke keleawe. Mai ka melemele a i ke gula ʻulaʻula kona ʻano. ʻOi aku ka nui o ka zinc e ʻoi aku ka ikaika a me ka ductile, a ʻoi aku ka melemele o ke kala. Ma muli o kona lōʻihi a me ka hana, hoʻohana mau ʻia ke keleawe i nā paipu paipu, nā ʻāpana mechanical, a me nā mea kani. Hoʻohana ʻia ia no nā mea hoʻonaninani ma muli o kona ʻano gula.
3. He aha ke keleawe?
E like me ke keleawe, ʻo ke keleawe he mea hao i hana ʻia me ke keleawe a me nā mea ʻē aʻe. Ma waho aʻe o ke keleawe, ʻo ka tin ka mea maʻamau i loaʻa i ke keleawe, akā hiki i ke keleawe ke loaʻa i ka zinc, arsenic, aluminika, silika, phosphorus, a me manganese. ʻO kēlā me kēia hui pū ʻana o nā mea e hoʻohua ai i nā waiwai like ʻole i loko o ka alloy hopena. ʻOi aku ka paʻakikī o ke keleawe ma mua o ke keleawe wale nō. Ma muli o kona ʻano gula a me kona ikaika, hoʻohana ʻia ke keleawe i nā kiʻi kiʻi, nā mea kani, a me nā mekala. Hoʻohana ʻia ia i nā noi ʻoihana e like me nā bearings a me nā bushings ma muli o kona haʻahaʻa haʻahaʻa metala. Loaʻa i ka Bronze nā hoʻohana nautical hou ma muli o kona kūpaʻa ʻana i ka corrosion. He mea hoʻokele maikaʻi ia o ka wela a me ka uila.
4. Okoa ma waena o ke keleawe, keleawe, a me ke keleawe
ʻO ke keleawe a me ke keleawe kekahi hapa o ke keleawe, ʻo ia ke kumu e paʻakikī ai i kekahi manawa ke haʻi i ka ʻokoʻa ma waena o ka metala a me kona mau ala. Eia naʻe, loaʻa i kēlā me kēia mea kekahi mau hiʻohiʻona a me nā waiwai e hoʻokaʻawale a ʻokoʻa mai nā mea ʻē aʻe. Eia kekahi mau ala e hoʻokaʻawale ai i ke keleawe, ke keleawe, a me ke keleawe.
● kala
He ʻulaʻula-ʻulaʻula kūʻokoʻa ke kala keleawe. ʻOi aku ka māmā o ke keleawe melemele-gula. ʻO Bronze, ʻo ia hoʻi, he gula ʻeleʻele a i ʻole ka waihoʻoluʻu sepia a loaʻa mau nā apo palupalu ma kona ʻili.
● kani
Hiki iā ʻoe ke hahau māmā i ka metala e hoʻāʻo ai inā he keleawe a i ʻole he mea hao. Hoʻopuka ke keleawe i kahi kani hohonu a haʻahaʻa. ʻO ke keleawe a me ke keleawe e hoʻopuka i kahi leo kiʻekiʻe, me ka leo keleawe e ʻoi aku ka mālamalama.
● Hoʻohui
ʻO ke keleawe kekahi mea i loko o ka papaʻaina manawa, ʻo ia hoʻi ka mea komo wale nō i ke keleawe maʻemaʻe he keleawe. Eia nō naʻe, i kekahi manawa e loaʻa nā mea haumia a i ʻole nā ʻili o nā mea ʻē aʻe i hui pū ʻia. ʻO Bronze kahi huila o nā mea keleawe a me ka tin, ʻoiai i kekahi manawa ua hoʻohui ʻia ke silika, manganese, aluminika, arsenic, phosphorus, a me nā mea ʻē aʻe. Hiki i ka Bronze a me ke keleawe ke komo i nā metala like, akā ʻoi aku ka nui o ke keleawe o kēia manawa i ka pakeneka kiʻekiʻe o Copper-ma kahi o 88% ma ka awelika.
● Mākēneki
ʻO ke keleawe, ke keleawe, a me ke keleawe, ʻaʻole ia he ferrous a ʻaʻole pono e hoʻopaneʻe. Eia nō naʻe, no ka mea, ʻo ke keleawe a me ke keleawe he mau mea hoʻohui, i kekahi manawa hiki ke komo i loko o ia mau ʻāpana hao a hiki ke ʻike ʻia e kahi magnet ikaika. Inā hoʻopaʻa ʻoe i kahi magnet ikaika i ka metala i nīnau ʻia a pane mai ia, a laila hiki iā ʻoe ke hoʻoholo i waho he keleawe.
● Paʻa
Paʻa, paʻa, ʻaʻole hiki ke hoʻololi ʻia ke keleawe. ʻO ke keleawe ka mea liʻiliʻi loa, me ke keleawe ma waena. Hiki i ke keleawe ke pohā ʻoi aku ka maʻalahi ma mua o nā mea ʻelua. ʻO ke keleawe, ʻo ia ka mea maʻalahi o nā ʻekolu. ʻOi aku ka kūpaʻa o ke keleawe ma mua o ke keleawe, akā ʻaʻole like me ke keleawe. E oxidize ke keleawe i ka manawa a hana i ka patina ʻōmaʻomaʻo e pale iā ia mai ka ʻino hou ʻana.
Makemake ʻoe e aʻo hou e pili ana i ka ʻokoʻa ma waena o ke keleawe a me ke keleawe? E hana pū ka poʻe akamai ma JINDAAI e koho i nā metala kūpono no kāu papahana aʻe. Kāhea i kēia lā e kamaʻilio me kahi hoa hui aloha a ʻike.
