ʻO nā pono o ke kaula alumini alumini

ʻO ke kaula alumini alumini kahi kaula mana waiwai hou e hoʻohana i ka ʻenehana holomua e like me ke kaʻina hana kaomi kūikawā a me ka mālama ʻana i ka annealing.Hoʻopili nā kaula alumini alumini no nā hemahema o nā kaula alumini maʻemaʻe i ka wā i hala, e hoʻomaikaʻi i ka conductivity uila, ka hana kulou, ke kūpaʻa ʻana a me ke kūpaʻa corrosion o ke kaula, a hiki ke hōʻoia i ka hana mau ʻana o ke kaula ke hoʻonui ʻia a wela no kahi manawa lōʻihi.ʻO ka hoʻohālikelike hana ma waena o ke kaula alumini alumini a me ke kaula keleawe keleawe penei:

ʻO ka hoʻokō

I ka hoʻohālikelike ʻana me nā kaula like ʻole, ʻo ka conductivity o ka alumini alloy conductor he 61% o ka mea maʻamau i hoʻohana ʻia i ke keleawe keleawe, ʻo ka gravity kikoʻī o ka alumini alumini he 2.7g/cm³, a ʻo ka gravity kikoʻī o ke keleawe he 8.9g/cm³.Ma lalo o ka leo like, alumini ʻO ke kaumaha o ke kaula uila alumini alumini ma kahi o hoʻokahi hapakolu o ke keleawe.Wahi a kēia helu ʻana, ʻo ke kaumaha o ke kaula uila alumini ka hapalua o ke kaula keleawe me ka mana like o kēia manawa ma lalo o ka manaʻo o ka hālāwai ʻana i ka conductivity uila like.

Kūleʻa kolo

ʻO ke kaʻina hana hoʻoheheʻe kūikawā a me ke kaʻina hana wela o ka mea hoʻokele alumini alumini e hoʻemi nui i ka "creep" o ka metala ma lalo o ka wela a me ke kaomi, ʻo ia ka mea like me ka hana kolo o ka conductor keleawe, a paʻa e like me ka pilina i hana ʻia. e ka mea lawe keleawe.

ʻO ke kūpaʻa ʻino

Ke hoʻohālikelike ʻia me nā kaula keleawe kumu, ʻoi aku ka kiʻekiʻe o nā kaula hao alumini alumini a hiki ke kū i nā ʻano ʻino like ʻole;ʻoi aku ka maikaʻi o ka pale ʻana i ka oxidation, a ʻo kā lākou oxidation a me ka corrosion kūpaʻa he 10 a 100 mau manawa o nā kaula keleawe kumu.I loko o nā kaiapuni i loaʻa i ka sulfur, e like me nā tunnels a me nā wahi like ʻole, ʻoi aku ka maikaʻi o ke kūpaʻa ʻana o nā kaula uila alumini alumini ma mua o nā kaula keleawe kumu.

Hana mīkini

ʻO ka mua, ka hana kulou.Wahi a GB/T12706 ma ka radius kulou o ka hoʻokomo ʻana i ke kaula keleawe, ʻo ka radius kuʻekuʻe o ke kaula keleawe he 10-20 mau manawa ke anawaena o ke kaula, a ʻo ka liʻiliʻi liʻiliʻi liʻiliʻi liʻiliʻi o ka alumini alloy power cable he 7 mau manawa ke anawaena o ke kaula.ʻO ka hoʻohana ʻana i ke kaula uila alumini alumini e hoʻemi ʻia ʻO ka wahi o ka hoʻonohonoho hoʻonohonoho e hoʻemi i ke kumukūʻai hoʻonohonoho a maʻalahi hoʻi e waiho.

ʻO ka lua, ka maʻalahi.ʻOi aku ka maʻalahi o nā uwea mana alumini alumini ma mua o nā kaula keleawe kumu, a ʻaʻole e pohā inā paha e hoʻokau pinepine ʻia.E ho'ēmi i nā pōʻino palekana huna i ka wā o ke kaʻina hana.

ʻO ke kolu, ka ikaika tensile a me ka elongation.ʻO ka ikaika tensile o nā kaula alumini alumini he 1.3 mau manawa o nā kaula keleawe keleawe, a hiki i ka elongation ke piʻi a ʻoi aku paha ma mua o 30%, kahi e hoʻonui ai i ka hilinaʻi a me nā aesthetics o ka hoʻonohonoho lōʻihi.
