Ma ka ʻenekinia hana, ʻekolu mau ʻano pale nui no ka ʻino kila.
1.ʻano kiʻiʻoniʻoni pale
Hoʻohana ʻia ke kiʻi pale e hoʻokaʻawale i ke kila mai ke ʻano a puni, e pale a hōʻemi paha i ka hopena hoʻopōʻino o ke ʻano corrosive waho ma ke kila.No ka laʻana, e hoʻoulu i ka pena, enamel, plastic, etc. ma ka ʻili kila;a i ʻole e hoʻohana i ka uhi metala ma ke ʻano he kiʻi pale, e like me ka zinc, tin, chromium, etc.
2.Ke ʻano palekana electrochemical
Hiki ke hoʻokaʻawale ʻia ke kumu kikoʻī o ka corrosion i ke ʻano o ka pale ʻana i kēia manawa a me ke ʻano palekana i kēia manawa.
Ua kapa ʻia ke ʻano o ka pale ʻole i kēia manawa ʻo ke ala anode mōhai.ʻO ia ka hoʻohui ʻana i kahi metala i ʻoi aku ka ikaika ma mua o ke kila, e like me ka zinc a me ka magnesium, i ka hale kila.No ka mea, he haʻahaʻa haʻahaʻa ko ka zinc a me ka magnesium ma mua o ke kila, zinc, a me ka magnesium e lilo i anode o ka pilahi corrosion.pōʻino (anode mōhai), ʻoiai ke pale ʻia ka hale kila.Hoʻohana pinepine ʻia kēia ʻano no nā wahi ʻaʻole maʻalahi a hiki ʻole ke uhi i ka papa pale, e like me nā paila mahu, nā paipu ma lalo o ka lepo o nā pūpū moku, nā hale ʻenekinia awa, nā hale alanui a me nā alahaka, etc.
ʻO ke ʻano o ka pale ʻana i kēia manawa, ʻo ia ke kau ʻana i kekahi mau mea hao a i ʻole nā mea metala refractory ʻē aʻe kokoke i ka hale kila, e like me ka hao kiʻekiʻe-silikona a me ke kala kala, a hoʻohui i ka pole maikaʻi ʻole o ka lako mana DC waho i ka hale kila pale, a me ka hoʻopili ʻia ka pou maikaʻi i ke ʻano metala refractory.Ma ka metala, ma hope o ka electrification, lilo ka metala refractory i anode a ua ʻino ʻia, a lilo ka hale kila i cathode a pale ʻia.
3.Taijin Chemical
Hoʻohui ʻia ke kila kalapona me nā mea e hiki ai ke hoʻomaikaʻi i ka pale ʻana i ka corrosion, e like me ka nickel, chromium, titanium, copper, etc., e hana i nā kila like ʻole.
Hiki ke hoʻohana ʻia nā ʻano hana i luna e pale ai i ka ʻino ʻana o nā pahu kila i loko o ka pahu kila, akā ʻo ke ala ʻoi aku ka maikaʻi a me ka ʻoi aku ka maikaʻi o ka hoʻomaikaʻi ʻana i ka momona a me ka alkalinity o ka ʻāpana a me ka hōʻoia ʻana i ka nui o ka mānoanoa o ka pale kila.
I loko o ka huahana hydration sima, ma muli o ka calcium hydroxide ma kahi o 1/5, ka pH waiwai o ka mea waena ma kahi o 13, a me ka hele ʻana o ka calcium hydroxide ke kumu o kahi kiʻiʻoniʻoni passivation ma ka ʻili o ka pahu kila e hana i kahi papa pale.I ka manawa like, hiki i ka calcium hydroxide ke hana pū me ka uaki CQ e hōʻemi i ka alkalinity o ke koneki, hiki ke luku ʻia ke kiʻi passivation, a aia ka ʻili kila i kahi kūlana hoʻāla.I loko o kahi wahi haʻahaʻa, hoʻomaka ka ʻino electrochemical ma luna o ka ʻili o ka pahu kila, ka hopena i ka haki ʻana o ka ʻiʻo ma ka pā.No laila, pono e hoʻomaikaʻi ʻia ke kūpaʻa carbonization o ke koʻikoʻi ma o ka hoʻomaikaʻi ʻana i ka paʻa ʻana o ke kaʻa.
Eia kekahi, loaʻa i nā ion chloride ka hopena o ka luku ʻana i ke kiʻi passivation.No laila, i ka wā e hoʻomākaukau ai i ka paʻakai paʻa, pono e kaupalena ʻia ka nui o ka paʻakai chloride.
