Me ke ʻano o nā hiʻohiʻona ʻenehana, ua hoʻonui hou ʻia ka hoihoi i ke kila ʻana. ʻO ke kila welu, ʻike ʻia hoʻi ʻo ke kila welu, ʻo ke ʻano o ke aniani kūlohelohe a me ka ʻōpala. Hoʻokumu ia i ka hoihoi a me ke ʻano ʻoiai e hoʻopiha ana i kahi nānā ʻenehana a ʻenehana paha.

E like me nā mea hale ʻē aʻe, ʻoi aku ka maikaʻi a me nā pōʻino ʻole o ke kila weathering. He mea nui e ʻike i ke ʻano o ke kila weathering a me kona mau waiwai.

He aha ke kila weathering?

ʻO ke kila welu, i kapa ʻia i kekahi manawa ke kila hoʻoheheʻe ʻana, he ʻano kila hoʻoheheʻe ʻana i kū i ka pala. Ma muli o kona hiki ke hana i kahi pale pale e kū'ē i ka'ōpala, he mea kaulana ke kila weathering no ke kiʻi kiʻi waho, ka hoʻolālā'āina, nā facades hoʻolālā a me nā noi waho'ē aʻe. ʻO ka papa pale, i kapa ʻia ʻo verdigris, hana ʻia i loko o ʻeono mahina wale nō o ka ʻike ʻana i ka oxygen a me ka wai.
ʻO Verdigris, ka mea e hana ai i kahi uhi ʻeleʻele ʻeleʻele, pale i ke kila mai ka ʻino hou ʻana mai ka ua, ka hau, ka noe, ka hau, ka ua a me nā kūlana ʻē aʻe. ʻO ka pōkole, ʻo ka ʻōpala kila, a me ka ʻōpala e hana i kahi pale pale. ʻOi aku ka maikaʻi o kēia papa ke ʻae ʻia e hoʻopaʻa a kūkulu ʻia i ka wā.

No ka hanaʻana i ka patina pale, pono e hōʻikeʻia ke kila i ka wai a me ka oxygen. Ke ʻike ʻia ke kila i nā mea ʻeleʻele, he mau mahina wale nō ka hana ʻana o kēia ʻōpala pale. Hoʻoikaika ka uhi a hoʻomau i ka hana hou ma lalo o nā ʻano ʻano like ʻole.

ʻO Cor-ten kahi inoa kālepa nona ka US Steel e wehewehe ana i ʻelua mau mea maikaʻi maikaʻi loa o ka Steel: ka pale ʻana i ka corrosion a me ka ikaika tensile. Ua hoʻokumu mua ʻia i nā makahiki 1930 e kōkua i ke kūkulu ʻana i nā kaʻa lanahu no ke ala kaʻa.

He kūleʻa ka huakaʻi kaʻa lanahu, a ua lilo ke kila Cor-Ten i mea kaulana i koho ʻia no nā kiʻi kiʻi kiʻi waho i nā makahiki 1960.

Ma waho aʻe o ka pale ʻana i ka corrosion, hoʻopau ke kila i ka pono no ka pena a i ʻole nā ​​​​mea pale ʻē aʻe.

No ke aha ka pale ʻana i ke kila?


ʻO ka patina i hana ʻia ma luna o ke kila hoʻoheheʻe ʻia he papa i loko a me waho. Ke ulu mau nei ka papa o waho a hoʻomohala hou ʻia me nā huahana pale ʻole adhesive hou. ʻO ka papa o loko ka mea nui i haku ʻia me nā ʻāpana liʻiliʻi paʻa.

ʻO ka hopena, e emi ana ka ʻeleu o waho a hoʻomaka ka ʻaoʻao o loko e lilo i mea kaulana. ʻO kēia ka mea e hāʻawi ai i ke kila weathering i kona ʻano ʻokoʻa a me kona ʻano. Ua ʻoi aku ka ʻeleʻele o ka ʻaoʻao o waho, a ʻoi aku ka paʻakikī o nā papa o loko.


ʻO ka papa o loko ka nui o ka goethite non-phase, ʻo ia ke kumu i loaʻa ai nā mea pale i ke kila weathering. No ke aha ia? No ka mea, e lilo ana ka hua ʻōpala i mea ʻeleʻele i hiki ʻole i ka wai ke ʻino hou i ka hale kila o loko.

Ke hoʻomohala maikaʻi ʻia, pono e maʻalahi ka ʻaoʻao o waho o ke kila welu a manaʻo ʻia e like me ka uhi pale.
