Kedu ihe na-ebute corrosion dị elu na igwe mmanụ ala?

1. Polysulfides na mmanụ ala na-eme ka nrụgide nrụgide dị elu nke igwe mmanụ ala

Ọtụtụ n'ime mmanụ ala na mba anyị nwere ọtụtụ polysulfides.N'oge usoro mmịpụta mmanụ, igwe mmanụ na akụrụngwa na-emebi ngwa ngwa site na polysulfides na mmanụ ala mgbe ha na-abanye na mmanụ ala, wee mepụta ụdị polysulfides dị iche iche n'elu elu nrụgide nke igwe mmanụ ala.Polysulfides, n'oge a na-arụ ọrụ nrụgide dị elu nke igwe mmanụ ala, polysulfides ndị a ga-eweta ọtụtụ ihe na-adịghị mma na mmanụ mmanụ.Tụkwasị na nke ahụ, mgbe akụrụngwa na-ekpuchi ikuku ruo ogologo oge, carbon dioxide na mmiri dị n'ikuku ga-emeghachi omume na akụkụ ndị mebiri emebi nke ngwá ọrụ ahụ, na-emecha na-eduga ná mbibi dị njọ nke ígwè na akụrụngwa mmanụ ala dum.

2. Sulfide na mmanụ ala na-akpata nrụrụ dị elu nke igwe mmanụ ala

Ihe na-akpata mbibi a bụ n'ụzọ bụ isi adịghị ọcha dị na ngwaahịa mmanụ ala.Akụkụ bụ isi nke adịghị ọcha ndị a bụ sulfide.Sulfide nwere ike meghachi omume na mmiri mmiri dị na mmanụ ala, na-ebute mmepụta nke nnukwu hydrogen sulfide na mmanụ ala.Hydrogen sulfide na-ebelata na acidic, na-ebute oke corrosion na igwe na akụrụngwa mmanụ ala.Na mgbakwunye, enwere ọnụ ọgụgụ dị ukwuu nke adịghị ọcha kemịkalụ na mmanụ ala, nke na-ebutekwa corrosion na igwe mmanụ ala na akụrụngwa nke ukwuu.

3. Chloride na mmanụ ala na-akpata nrụrụ dị elu nke igwe mmanụ ala

Dị ka nyocha, ọtụtụ mmanụ ala ugbu a nwere nnukwu mmiri nnu.Ọ bụrụ na mmiri nnu na-abanye kemịkalụ hydrolysis, a ga-agbanwe ya ka ọ bụrụ hydrochloric acid.Maka igwe mmanụ ala, hydrochloric acid bụ otu n'ime isi ihe na-eduga n'ikuku nke igwe na akụrụngwa mmanụ.Maka igwe na akụrụngwa mmanụ ala, na-ebute ọnọdụ mmebi dị njọ, si otú a belata ogo na nchekwa nke igwe na akụrụngwa mmanụ ala.
