He aha nā kumu o ka corrosion kiʻekiʻe i ka mīkini ʻaila?

1. ʻO nā polysulfides i loko o ka ʻaila ke kumu i ka pohō kiʻekiʻe o nā mīkini ʻaila

ʻO ka hapa nui o ka ʻaila i ko mākou ʻāina he nui nā polysulfides. I ka wā o ke kaʻina hana ʻaila, hiki ke ʻino ʻia nā mīkini ʻaila a me nā mea hana e nā polysulfides i loko o ka ʻaila i ka wā e hui ai lākou me ka ʻaila, a laila hana i nā ʻano polysulfides ma ka ʻili kiʻekiʻe o ka mīkini ʻaila. ʻO nā Polysulfides, i ka wā o ka hana kiʻekiʻe o ka mīkini ʻaila, e lawe mai kēia mau polysulfides i nā kumu instability i ka mīkini ʻaila. Eia kekahi, i ka wā lōʻihi e hōʻike ʻia ai nā mea hana mīkini i ka lewa, e pane ka carbon dioxide a me ka makū i ka lewa me nā ʻāpana ʻino o nā mea hana mechanical, a laila e alakaʻi i ka ʻinoʻino o nā mīkini a me nā mea hana a pau.

2. ʻO ka sulfide i loko o ka ʻaila ka mea e hoʻopōʻino ai i nā mīkini ʻaila kiʻekiʻe

Hoʻokumu nui ʻia kēia hanana corrosion e nā haumia o nā huahana petroleum. ʻO ka mea nui o kēia mau haumia he sulfide. Hiki i ka Sulfide ke hana kemika me ka makū i loko o ka ʻaila, ka hopena i ka hana ʻana i ka nui o ka hydrogen sulfide i ka ʻaila. Ke emi nei ka hydrogen sulfide a me ka ʻakika, e hoʻopōʻino ai i nā mīkini ʻaila a me nā mea hana. Eia kekahi, aia ka nui o nā mea haumia kemika i loko o ka ʻaila, kahi e hoʻoulu ai i ka corrosion i nā mīkini a me nā mea hana i ka nui.

3. ʻO Chloride i loko o ka ʻaila ka mea e hoʻopōʻino ai i nā mīkini ʻaila kiʻekiʻe

Wahi a nā noiʻi, aia ka nui o ka aila i kēia manawa ka nui o ka wai paʻakai. Inā hele ka wai paʻakai i ka hydrolysis kemika, e hoʻololi ʻia i loko o ka waikawa hydrochloric. No nā mīkini ʻaila, ʻo ka waika hydrochloric kekahi o nā kumu nui e alakaʻi ai i ka corrosion o nā mīkini a me nā mea hana. No nā mīkini ʻaila a me nā mea hana, Hoʻoulu i nā kūlana corrosion koʻikoʻi, a laila e hōʻemi i ka maikaʻi a me ka palekana o nā mīkini a me nā mea hana.
