He moʻolelo lōʻihi ko ka mea i kapa ʻia ʻo hao.Hoʻohana nui ʻia nā huahana hao kuʻuna no ka hoʻonani ʻana i nā hale, nā hale a me nā māla.Ua hana ʻia nā huahana hao mua loa ma kahi o 2500 BC, a ua manaʻo nui ʻia ke aupuni Heta ma Asia Minor ʻo ia ka wahi hānau o ka hana hao.
Ua hana ka poʻe ma ka ʻāina Heta o Asia Minor i nā mea hao like ʻole, e like me nā ipu hao, nā puna hao, nā pahi kīhini, nā ʻoki, nā kui, nā pahi kaua, a me nā ihe.ʻO kēia mau mea hao he ʻōkole a maikaʻi paha.ʻO ka ʻōlelo koʻikoʻi, pono e kapa ʻia kēia mau mea hao hao i pololei.Ke hala nei ka manawa, ua ulu ka ʻepekema a me ka ʻenehana, a ua loli ka nohona o nā kānaka a me nā mea e pono ai i kēlā me kēia lā i kēlā me kēia lā.I loko o nā lima o nā hanauna o ka mea hana hao a i loko o ka umu ahi o ka manaʻo, ua nalowale ka hao i kāna "ʻele" kahiko a ʻālohilohi.no laila ua hānau ʻia kahi ʻano ʻano pau ʻole o nā huahana kiʻi hao.Ua nalowale ka ʻoihana kahiko o ka ʻeleʻele, a ua hoʻopau ʻia ka hao e ka hoʻomohala ʻenehana wikiwiki i ka mōʻaukala o ka hao curving.
1. Ka hao a me kona kaiapuni

ʻO ke kiʻi hao he lokahi a he hōʻailona me ke kaiapuni a puni.Ma ke kauhale hoʻokahi, ʻokoʻa kēia i kekahi.ʻOkoʻa ka A mai ka B. Hiki i nā kānaka ke hoʻokaʻawale i nā ʻano he nui i kahi wahi liʻiliʻi loa, mai kahi home a i kekahi, e noʻonoʻo ana i kahi hoʻolālā nani maikaʻi loa, en curvature nānā ʻia a i ʻole ke ʻano haʻalulu!

He kūpono, nani, me ka paʻi kiʻekiʻe i hiki i ka poʻe hele wāwae ke kū a mahalo iā lākou.Hōʻike kēia mau mea hana hao i nā ʻono moʻomeheu o nā mea nona a me nā hui mea kūʻai aku, ʻoi aku ka nui o kekahi mau ʻoliʻoli moʻomeheu a me nā wahi ʻai.Hiki i ka poʻe waiwai a me ka hanohano ke loaʻa i nā aliʻi o nā huahana hao makamae, nā mea maʻamau mai ka ʻumikumamāhiku a i ʻole ʻumikūmāwalu kenekulia.

2. Enā huahana launa pū
ʻO ka hapa nui o nā huahana kiʻi hao e hoʻokō i ka pale kaiapuni.Ma waho aʻe o kēia mau waiwai eco-friendly o nā huahana kiʻi hao, ua maʻalahi lākou i ka hana a me ka pihi.Me ka hana maikaʻi, ke kaʻina hana kūpono, ka hana ikaika, ʻike maikaʻi ʻia nā huahana, e hoʻopau ana i nā burrs a me nā ʻōpala;ʻO kēia mau ʻenehana i hui pū ʻia me ka lāʻau anti-corrosion a me ka anti-rust me ka hoʻohana ʻana i ka uhi lole e hāʻawi i nā kānaka i nā huahana lōʻihi.

I kēia mau lā, makemake nui ka poʻe i nā huahana kiʻi hao ma muli o nā kumu aboce.Ka ikaika, ke kū'ē kiʻekiʻe i ka makani a me ka ua, ka hoʻohana lōʻihi, anti-insect etc.

3. ʻEkonomikakaʻina hana.
ʻO ke kumukūʻai o ka hana hao kekahi mea ʻē aʻe.I kēia mau lā, ʻaʻole ka hana hou ʻana a me ka hoʻohana nui ʻana i nā kiʻi hao.ʻOiai i ke kenekulia 21, ʻaʻohe metala koʻikoʻi ma mua o ka hao, a ua ʻoiaʻiʻo kēia no nā makahiki 3,000.Hiki ke hana ʻia nā mea hao ma nā wahi a pau o ka honua, a hiki i nā ʻano hana like ʻole ke hana i nā ʻano metala me ka nui o nā waiwai.Ma ka mōʻaukala, ʻekolu mau ʻano hao: hao hao, hao hoʻolei, a me ke kila.Ua ʻike nā mea hana lima i ka ʻike a me ka nānā ʻana i kēlā me kēia ʻano a hoʻohana iā lākou no nā kenekulia.ʻAʻole hiki i ke kenekulia 19 ka hoʻomaopopo ʻana i nā ʻokoʻa i waena o lākou, ʻo ia hoʻi ke kuleana o ke kalapona.

ʻO ka hao i hana ʻia he hao maʻemaʻe, he metala hiki ke hana maʻalahi ʻia i loko o kahi paʻi a paʻakikī a ductile naʻe, ʻo ia hoʻi, hiki ke hana ʻia i ke ʻano.ʻO ka hao hoʻolei, ma kekahi ʻaoʻao, loaʻa ka nui o ke kalapona, ma kahi o ʻelima pakeneka, i hui pū ʻia me ka metala (ma ka hui kemika a me ke kino).He huahana kēia, ʻaʻole like me ka hao i hoʻoheheʻe ʻia, hiki ke hoʻoheheʻe ʻia i loko o nā kapuahi lanahu a pēlā e ninini ʻia ai a hoʻolei ʻia i loko o nā mole.He paʻakikī loa akā he palupalu.Ma ka mōʻaukala, ʻo ka hao hao ka mea i hoʻohana mua ʻia e nā mea hana metala Kina ma kahi o 2,500 mau makahiki aku nei.

No ke kenekulia a me ka hapalua i hala, ʻo ke ʻano nui o ka hao he kila.ʻO ke kila ka nui o nā mea waiwai, nona nā waiwai i hilinaʻi ʻia ma ka nui o ke kalapona i loko-ma waena o 0.5 a me 2 pākēneka-a me nā mea hoʻohuihui ʻē aʻe.ʻO ka mea maʻamau, hoʻohui ke kila i ka paʻakikī o ka hao i hana ʻia me ka paʻakikī o ka hao, no laila, ma ka mōʻaukala, ua waiwai nui ia no nā hoʻohana e like me nā lau a me nā pūnāwai.Ma mua o ka waena o ke kenekulia 19, e hoʻokō i kēia koena o nā waiwai i koi ʻia i ka hana hana kiʻekiʻe, akā ʻo ka loaʻa ʻana o nā mea hana hou a me nā ʻenehana, e like me ka hoʻoheheʻe ʻana i ka puʻu ahi a me ke kaʻina Bessemer (ke kaʻina hana inexpensive mua no ke kila hana nui. mai ka hao), hana ʻia ke kila me ka maʻalahi a me ka nui, e hoʻoneʻe ana i kona mau hoa hakakā no nā mea hoʻohana āpau.

ʻO ke kumu ma hope o kēia kūleʻa kiʻi hao, ʻo ia wale nō ke kumu kūʻai haʻahaʻa.
