Ingaba ivelufa ichasene njani nomhlwa? Izizathu, amanyathelo, kunye neendlela zokukhetha zonke zilapha!

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.
