Iyo nzira inoshandiswa kubvisa oxide ganda uye ngura pamusoro pesimbi kubva pamusoro pesimbi nesimbi, uchishandisa acidic mhinduro, inoratidzwa sekunhonga.
Iron oxides yakadai se oxide scale uye rust (Fe3O4, Fe2O3, FeO, nezvimwewo) inopinda maitiro emakemikari ane acid solutions, inogadzira munyu unonyunguduka mumushonga we acid uye unobviswa.
kuita kemikari inogadziriswa ine acidic solution, zvichiita kuti pave nekuumbwa kwemunyu unonyungudika unozobudiswa.MaAcids ekunhonga maitiro anosanganisira sulfuric acid, hydrochloric acid, phosphoric acid, nitric acid, chromic acid, hydrofluoric acid, uye composite acids.Kunyanya, sulfuric acid uye hydrochloric acid isarudzo dzinofarirwa.Nzira dzekunhonga dzinosanganisira kunyudza kunyudza, kupfapfaidza pickling, uye kubvisa ngura yeasidhi.

Kazhinji, kunyudza kunyudza kunowanzoshandiswa, uye nzira yekupfapfaidza inogona kushandiswa mukugadzirwa kwakawanda

Masimbi esimbi anowanzo kuchekwa mu10% kusvika 20% (nevhoriyamu) sulfuric acid solution pakudziya kwekushanda kwe40°C.Kutsiviwa kwemushonga wekunhonga kunove kwakakosha kana iron inopfuura 80g/L uye ferrous sulfate inodarika 215g/L mumushonga.

Pakamuri tembiricha,pickling simbiine 20% kusvika 80% (volume) hydrochloric acid solution hainyanyi kuita ngura uye hydrogen embrittlement.
Nekuda kwekuzivikanwa kwekuora kweasidhi kune simbi, corrosion inhibitors inounzwa.Mushure mekucheneswa, iyo simbi yepasi inoratidza chitarisiko chesirivha-chena, panguva imwe chete ichiitwa passivation kuti iwedzere huturu hwekuramba hunhu hwesimbi isina tsvina.

Vimba kujekesa uku kunoratidza kunobatsira.Kana mimwe mibvunzo ikamuka, ndapota usazeza kutaura.
