ʻenehana hoʻomaʻamaʻa ʻili o ke ala hao

He maʻalahi ka ʻōpala i ke ea a me ka wai. Wahi a nā ʻikepili pili, ʻo ka poho makahiki i hoʻokumu ʻia e ka corrosion e pili ana i kahi hapaʻumi o ka hana kila holoʻokoʻa. I mea e hana ai i ke kila auwai ke kū'ē i ka corrosion, a ma ka manawa like e hāʻawi i ka hiʻohiʻona nani o ka huahana, no laila e hoʻohana mau ʻia i ke ʻano o ka mālama ʻana i ka honua.(kaila galvanizedkila)

ʻO ka Galvanizing kahi ʻano lapaʻau ili me ka hana kiʻekiʻe a me ka lakio kumu kūʻai. No ka mea, ʻaʻole maʻalahi ka hoʻololi ʻana o ka zinc i ka ea maloʻo, a i ka ea humid, hiki i ka ʻili ke hoʻohua i kahi kiʻiʻoniʻoni galvanized nui loa, ma hope o ka mālama ʻana i ka galvanized o ka ʻili kila a maikaʻi loa, akā he ikaika ke kūpaʻa corrosion.

I ke kūlana wai o ka zinc, ma hope o ke kaʻina hana kino a me ke kemikaʻo ia, ʻaʻole wale kahi papa zinc ʻoi aku ka mānoanoa i uhi ʻia ma ke kahawai kila, akā ua hoʻokumu ʻia kahi ʻāpana zinc-hao. ʻAʻole i loaʻa i kēia ʻano plating nā hiʻohiʻona pale corrosion o ka galvanizing uila, akā loaʻa pū kekahi i ke kūpaʻa corrosion ikaika ʻole o ka galvanizing uila ma muli o ka zinc a me ka hao hao. No laila, ʻoi aku ka maikaʻi o kēia ʻano plating no nā ʻano like ʻole o ka waikawa ikaika, ka noe alkali a me nā wahi ʻino ikaika ʻē aʻe.

Nui nā mea hana kila kanal, pono ʻoe e poli i kāu eʻAe i ke kūʻai ʻana, mai ʻimi makapō i nā kumukūʻai haʻahaʻa, koho i kahi mea hana hilinaʻi ʻoi aku ka nui ma mua o ke kumukūʻai!
