ʻāpana keleawe

ʻO ka wehewehe pōkole:

ʻO ke keleawe keleawe he huila keleawe a me ka zinc, ma nā ʻāpana hiki ke hoʻololi ʻia e hoʻokō ai i nā ʻano mechanical, uila, a me nā waiwai kemika.He mea hoʻohui i hoʻohui ʻia: hiki i nā ʻātoma o nā mea ʻelua ke hoʻololi kekahi i kekahi i loko o ka hale aniani like.

Hoʻolauna i nā ʻāpana keleawe keleawe

Ua like ke keleawe me ke keleawe, kekahi huila me ke keleawe e hoʻohana ana i ka tin ma mua o ka zinc. Hiki i ke keleawe a me ke keleawe ke hoʻokomo i nā liʻiliʻi liʻiliʻi o nā mea ʻē aʻe e like me arsenic, lead, phosphorus, aluminika, manganese, a me ke silika.Ma ka mōʻaukala, ʻaʻole i kūlike a maopopo ka hoʻokaʻawale ʻana ma waena o nā ʻāpana ʻelua, a ʻo ka hana hou i nā hale moʻomeheu a me nā archeology ke pale nui nei i nā huaʻōlelo ʻelua no nā mea mōʻaukala e makemake ai i ka "copper alloy".

He mea kaulana loa ke keleawe no ka hoʻonani ʻana ma muli o kona ʻano nani a me ke gula;hoʻohana ʻia no nā huki huki a me nā kī puka.Ua hoʻohana nui ʻia e hana i nā kīʻaha ma muli o nā waiwai e like me ka loaʻa ʻana o kahi helu heheʻe haʻahaʻa, hiki ke hana kiʻekiʻe (me nā mea hana lima a me nā mīkini hoʻohuli a me nā mīkini wili o kēia manawa), ka lōʻihi, a me ka conductivity uila a me ka wela.

Hoʻohana i nā ʻāpana keleawe keleawe

Hoʻohana mau ʻia ke keleawe keleawe i nā noi kahi e koi ʻia ai ka pale ʻana i ka corrosion a me ka haʻahaʻa haʻahaʻa, e like me nā loka, nā hinges, nā pahu, nā bearings, nā pahu pahu, nā zippers, plumbing, hose couplings, valves, a me nā pahu uila a me nā kumu.Hoʻohana nui ʻia ia no nā mea kani e like me nā pū a me nā bele, a hoʻohana ʻia hoʻi ma ke ʻano he keleawe i ka hana ʻana i nā mea kāhiko, nā mea nani, a me nā mea hoʻonaninani ʻē aʻe.ʻO ke ʻano o ke keleawe, ma ke ʻano he 66% keleawe a me 34% zinc, he mea kūpono ia no nā mea hoʻonaninani keleawe, no ka mea e hōʻike ana i ke kūpaʻa ʻoi aku i ka ʻino.Hoʻohana pinepine ʻia ke keleawe i nā kūlana he mea nui ʻaʻole e paʻi ʻia nā huna ahi, e like me nā mea pono a me nā mea hana i hoʻohana ʻia ma kahi kokoke i nā mea pahū a i ʻole nā mea pahū.
