Liaparo tse thibelang kutu ka kakaretso li arotsoe ka liphahlo tse tloaelehileng tse thibelang ho bola le tse thibelang kutu e boima, e leng seaparo sa bohlokoahali sa lipente.Liaparo tse tloaelehileng tse khahlanong le kutu li phetha karolo ea ho thibela ho bola ha tšepe tlas'a maemo a tloaelehileng le ho sireletsa bophelo ba tšebeletso ea litšepe tse se nang ferrous;litlolo tse thibelang ho bola ha boima li bapisoa le liphahlo tse tloaelehileng tse thibelang kutu, tse ka sebelisoang libakeng tse batlang li le thata tse senyang 'me li na le bokhoni ba ho A mofuta oa ho thibela ho bola o finyellang nako e telele ea tšireletso ho feta liphahlo tse tloaelehileng tse thibelang ho bola.Molao-motheo oa anti-corrosion oa liphahlo tse akaretsang tse thibelang ho bola o ka lehlakoreng la k'hemistri, fisiks le electrochemistry.E latelang ke tlhaloso e qaqileng:
1. Molao-motheo oa lik'hemik'hale oa anti-corrosion
Molao-motheo oa lik'hemik'hale oa anti-corrosion ke ho fokotsa lintho tse kotsi tsa acid-base hore e be lintho tse sa jeleng paate le tse se nang kotsi ho sireletsa lisebelisoa tse sekoahelong se thibelang kutu ho tsoa linthong tse senyang.Lik'hemik'hale tse ling tsa amphoteric, tse kang aluminium hydroxide, barium hydroxide le zinc oxide, hangata li kenngoa liphahlo tse thibelang mafome.Lintho tsena li ka sebetsa habonolo ka asiti le lintho tse kotsi tsa alkali ho fihlela litlamorao tsa anti-corrosion.

2. Molao-motheo oa 'mele oa anti-corrosion
Molao-motheo oa 'mele oa anti-corrosion ke ho arola thepa e sirelelitsoeng ho lintho tse senyang tse ka ntle ka seaparo se thibelang ho bola.Molao-motheo oa 'mele oa pente e khahlanong le mafome ke ho sebelisa moemeli oa ho etsa filimi ho fumana lesela le teteaneng le thibelang kutu ho arola tšenyo ea phello e khahlanong le kutu ho thepa e sirelelitsoeng.Ka mohlala, pente e nang le loto le oli li ka etsa sesepa sa loto ho netefatsa hore ho na le anti-corrosion coating The density.

3. Phello ea electrochemical ea anti-corrosion
Phello ea electrochemical ea anti-corrosion e bolela ho eketsoa ha lintho tse ling tse khethehileng ho pente e khahlanong le mafome, e le hore ha mongobo le oksijene li feta pente e khahlanong le mafome, li tla itšoara ho theha li-ion tse khahlanong le kutu, li feta holim'a metsi. litšepe tse kang tšepe, 'me kahoo thibela li-ion tsa tšepe.Ho qhalana, ho finyella morero oa ho thibela ho bola, ntho e tloaelehileng ka ho fetisisa ea ntho ena e khethehileng ke chromate.

Libaka tsa ts'ebeliso ea li-anti-corrosion li kenyelletsa lintlha tse hlano tse latelang:
① Boenjiniere bo ntseng bo tsoela pele ho tloha lebopong: lits'ebetso tsa kantle ho naha, meaho e lebopong le lebopong la leoatle, lipolanete tsa ho cheka oli;
②Lipalangoang tsa sejoale-joale: literene tse lebelang litseleng tse kholo, marokho, likepe, likotlolo, literene le lits'ebeletso tsa terene, likoloi, lisebelisoa tsa boema-fofane;
③Indasteri ea matla: lisebelisoa tsa haeteroliki, litanka tsa metsi, litanka tsa khase, lisebelisoa tse hloekisang peterole, lisebelisoa tsa polokelo ea peterole (lipeipi tsa oli, litanka tsa oli), lisebelisoa tsa phepelo ea motlakase le phetoho, matla a nyutlelie, merafo ea mashala;
④ Likhoebo tse kholo tsa indasteri: lisebelisoa tsa ho etsa pampiri, lisebelisoa tsa bongaka, lijo le lisebelisoa tsa lik'hemik'hale, mabota a kahare le kantle a lijana tsa tšepe, liphaephe, litanka tsa polokelo tsa lik'hemik'hale, tšepe, limela tsa petrochemical, merafo le ho qhibiliha, lisebelisoa tsa semela sa samente, fatše, mabota le likarolo tsa samente. ka mecha ea litaba e senyang;
⑤ Mehaho ea 'masepala: liphaephe tsa khase le lisebelisoa tsa tsona (tse kang litanka tsa khase), lipeipi tsa khase ea tlhaho, lisebelisoa tsa metsi a nooang, lisebelisoa tsa ho lahla litšila, joalo-joalo.
