Hana ʻia ka uea puʻupaʻa mai ke koʻokoʻo kiʻekiʻe-haʻahaʻa haʻahaʻa-e like me nā kaʻina hana, e like me ke kaha kiʻi ʻana, pickling, wehe ʻōpala, kiʻekiʻe-annealing wela, wela-wīwī a me ka hoʻoluʻu. Ua māhele ʻia ka uea puʻupuʻu i ka uea wela -dip galvanized uea a me ke anu-dip galvanized wire (electrogalvanized wire). ʻO nā ʻokoʻa ma waena o lākou penei:
uea hao hao wela:-Hana ʻia ka hoʻoheheʻe ʻana -wela ma ka hoʻoinu ʻana i loko o ka zinc hehee. ʻO kēia ka hopena i kahi kaʻina hana wikiwiki a me kahi uhi mānoanoa, akā ʻaʻole kūlike. He ʻeleʻele kona kala, hoʻopau i ka nui o ka zinc, a hoʻokumu i kahi papa permeation me ka metala kumu, e hāʻawi ana i ke kūpaʻa maikaʻi loa. Hiki ke mālama i kāna hana no nā makahiki he nui ma nā kaiapuni waho. Hoʻohana nui ʻia ka uea wela wela - i nā mea hana kemika, ka ʻaila ʻaila, ka ʻimi kai, nā hale metala, ka hoʻoili mana, a me ka hana moku. I nā makahiki i hala iho nei, ua hoʻohana nui ʻia ia i ka mahiʻai, e like me ka pesticide spraying a me nā hale ʻōmaʻomaʻo, a i ke kūkulu ʻana, e like me ka hāʻawi ʻana i ka wai a me ke kinoea, ka uila uila, ka scaffolding, nā alahaka, a me nā alaloa.
Ua -ho anu anu (electrogalvanized):Hana ʻia ka uea uʻi anuu -puʻu ma o ka hoʻokuʻu ʻana i ke au uila unidirectional ma o ka pahu hoʻopalapala uila, e uhi mālie i ka metala me ka zinc. He lohi ka hana ʻana o kēia ʻano hana, a loaʻa i kahi ʻāpana like ʻole a lahilahi (maʻamau 3-15 microns). ʻOiai ʻālohilohi ka uhi ʻana, maikaʻi ʻole ke kūpaʻa ʻana i ka corrosion a e ʻōpala i loko o kekahi mau mahina. Hoʻohālikelike ʻia me ka electrogalvanizing, ʻoi aku ka maikaʻi o ke kumu kūʻai ʻana -dip galvanizing a he haʻahaʻa ka hopena o ke kaiapuni ma mua o ka electroplating.
