ʻO ka manaʻo nui ia i nā paipu kila, kahi e hiki ai i ka corrosion reactions, a aia kekahi pilikia huna i ka pōʻino o nā lako ma hope o ka corrosion.Ma hope o ka wehe ʻana i nā ʻano ʻaila a pau, ka ʻōpala, ka unahi, nā wahi wili a me nā lepo ʻē aʻe, hiki iā ia ke hoʻomaikaʻi nui i ka pale ʻana o ke kila.

Ina he lepo ma ka ili o kapaipu kila kila, pono e hoʻomaʻemaʻe mechanically a laila degreased.ʻO ka loaʻa ʻana o ka momona ma ka ʻili e pili i ka maikaʻi o ka pickling a me ka passivation.No kēia kumu, ʻaʻole hiki ke haʻalele ʻia ka degreasing.Hiki iā ʻoe ke hoʻohana i ka lye, emulsifiers, organic solvents a me ka mahu.

ʻO ka passivation ke kaʻina hana hope loa i ka hoʻomaʻemaʻe kemika a he hana nui.ʻO kāna kumu e pale i ka corrosion o ka mea.No ka laʻana, ma hope o ka paila ua pickled, holoi me ka wai, a holoiʻia, ka metala ili maʻemaʻe loa, loa ho'ā, a maʻalahi hiki i ka corrosion, no laila, pono e passivated koke e hana i ka pale kiʻiʻoniʻoni ma ka hoʻomaʻemaʻe metala ili e emi. ʻinoʻino.
