Ukonakala kweentsimbi kubangelwa ikakhulu kukubola kweekhemikhali kunye ne-electrochemical corrosion, kwaye ukubola kwezinto ezingezizo ezentsimbi ngokuqhelekileyo kubangelwa ngumonakalo othe ngqo wemichiza kunye nomzimba.
1. Ukonakala kweekhemikhali
I-medium ejikelezileyo isebenzisana ngqo neekhemikhali kunye nesinyithi phantsi kwemeko yokungabikho kwangoku, kwaye ibangela ukuba ibhujiswe, njengokubola kwesinyithi ngegesi eyomileyo enobushushu obuphezulu kunye nesisombululo esingenawo i-electrolytic.
2. I-Electrochemical corrosion
Uqhagamshelwano lwesinyithi kunye ne-electrolyte ukuvelisa ukuhamba kwe-electron, okuya kuzitshabalalisa kwisenzo se-electrochemical, eyona ndlela iphambili yokubola.
I-acid-base yetyuwa yesisombululo esiqhelekileyo, i-atmospheric corrosion, i-corrosion yomhlaba, i-corrosion yamanzi olwandle, i-microbial corrosion, i-pitting corrosion kunye ne-crevice corrosion ye-stainless steel, njl., zonke ziyi-electrochemical corrosion.
I-electrochemical corrosion ayikwenzeka kuphela phakathi kwezinto ezimbini ezinokudlala indima yeekhemikhali, kodwa nangenxa yokwahluko ekugxininiseni isisombululo, ukuxinwa kwe-oksijeni ejikelezileyo, umehluko omncinci kwisakhiwo sezinto eziphathekayo, njl. kwikhono iveliswa, kwaye amandla okubola afunyenwe. , Ukuze isinyithi esinamandla aphantsi kwaye kwindawo yebhodi efanelekileyo ilahlekelwa yilahleko.
