Lapaʻau ʻili alumini

ʻO ka hoʻomaʻamaʻa ʻana i ka ʻili alumini he kaʻina hana e hoʻohana ai i kahi kaʻina kikoʻī e hoʻololi i ka ʻili o ka aluminika a me kāna mau mea hoʻohuihui, me ka manaʻo e hoʻomaikaʻi i kona mau ʻili, hoʻomaikaʻi i ka pale ʻana i ka corrosion a me ka nani. ʻO ka hoʻomaʻamaʻa ʻana i ka ʻili alumini ka mea nui e pili ana i ka anodizing, electroplating, spray coating, chemical treatment a me nā ʻano hana ʻē aʻe e hoʻokō ai i nā koi hana o ka ʻili o nā mea alumini ma nā ʻano ʻoihana like ʻole.

ʻO ka mea mua, ʻo ka anodizing kahi hana lapaʻau alumini maʻamau i hoʻohana ʻia. Ma ka anodizing i ka mea alumini i loko o kahi electrolyte kikoʻī, ua hoʻokumu ʻia kahi kiʻi ʻoniʻoni ʻoniʻoni a me ke ʻano like, e hoʻomaikaʻi ai i ka paʻakikī o ka ʻili, hoʻopaʻa i ke kūpaʻa a me ka pale ʻana o ka mea alumini. ʻO ke kūpaʻa ʻino.

ʻO kēia kiʻiʻoniʻoni oxide he ʻano pore a kūpono ia no ke kala ʻana, ke kala a i ʻole ke sila ʻana no ka loaʻa ʻana o nā kala like ʻole a me nā hopena hoʻonaninani. ola o na mea alumini.

ʻO ka lua, ʻo ka electroplating kekahi ʻano hana lapaʻau alumini maʻamau, e komo pū me ka nickel plating, chromium plating, zinc plating a me nā ʻano hana hoʻoheheʻe metala ʻē aʻe. ʻO ka ʻili o nā huahana alumini electroplated maikaʻi ke kūpaʻa corrosion, aesthetics a me nā waiwai mechanical, a kūpono no ka hoʻonani a me ka pale. Hiki i ke kaʻina hana electroplating ke pale pono i ka corrosion oxidation o nā mea alumini, hoʻonui i kona ola lawelawe, a hoʻomaikaʻi i kona ʻano maikaʻi. Hoʻohana nui ʻia ia i nā ʻāpana kaʻa, nā mea hale, nā mea hoʻonaninani a me nā māla ʻē aʻe.

ʻO ka uhi ʻana o nā mea alumini he ʻano hana lapaʻau maʻamau. ʻO ka pīpī ʻana i ka resin epoxy, polyester, ka pena fluorocarbon a me nā uhi ʻē aʻe ʻaʻole hiki ke hāʻawi wale i nā koho waihoʻoluʻu waiwai a me nā hopena hoʻonaninani, akā hiki ke pale pono i nā mea alumini mai ka pōʻino. ʻO ka ʻino a me ka hoʻokahe. He kūpono ka hoʻopili ʻana no ka mālama ʻana i nā puka alumini alumini a me nā puka makani, nā lumi lā, nā paneli hoʻonaninani alumini a me nā huahana ʻē aʻe.

Eia kekahi, ʻo ka hoʻomaʻamaʻa kemika kekahi o nā ʻano hana lapaʻau alumini maʻamau, me ka pickling, soaking, solvent hoʻomaʻemaʻe a me nā ʻano kemika ʻē aʻe, i hoʻohana ʻia e hoʻoneʻe i ka unahi oxide a me nā pollutants ma luna o ka ʻili o nā mea alumini e hāʻawi i kahi maʻemaʻe a me ke ʻano like. no nā kaʻina hana lapaʻau ma hope. He kūpono kēia ʻano hana lapaʻau no nā huahana alumini i loaʻa i nā koi hoʻomaʻemaʻe maʻemaʻe ma ka uila, kamaʻilio, uila a me nā māla ʻē aʻe.

ʻO ka hōʻuluʻulu ʻana, ʻo ka hoʻomaʻamaʻa ʻana i ka alumini ka hoʻololi ʻana i ka ʻili o ka alumini a me kāna mau mea hoʻohuihui ma o ke ʻano o nā kaʻina hana a me nā ʻano e hoʻomaikaʻi ai i kona ʻano o ka ʻili, hoʻonui i ka pale ʻana i ka corrosion a me nā aesthetics. . Hiki ke koho 'ia ke kaʻina hana lapaʻau kūpono e like me nā pono kiko'ī e loaʻa ai ka hopena maikaʻi loa a me ka hana.
