Njira yomwe imagwiritsidwa ntchito pochotsa khungu la oxide ndi dzimbiri pamwamba pa chitsulo kuchokera pazitsulo ndi chitsulo, pogwiritsa ntchito njira za acidic, zimatchedwa pickling.
Iron oxides monga oxide scale ndi dzimbiri (Fe3O4, Fe2O3, FeO, etc.) amakumana ndi mankhwala ndi mankhwala a asidi, kupanga mchere womwe umasungunuka mu asidi ndi kuchotsedwa.
amakumana ndi ma chemical reaction ndi ma acidic solution, zomwe zimapangitsa kupanga mchere wosungunuka womwe umachotsedwa.Acids ku pickling ndondomeko akuphatikizapo sulfuric acid, hydrochloric acid, phosphoric acid, nitric acid, chromic acid, hydrofluoric acid, ndi kompositi zidulo.Nthawi zambiri, sulfuric acid ndi hydrochloric acid ndizosankhidwa bwino.Njira zodulira zichulukidwe zimaphatikizira kumiza m'madzi, kukhetsa kutsitsi, ndi kuchotsa dzimbiri la asidi.

Nthawi zambiri, pickling yomiza imagwiritsidwa ntchito, ndipo njira yopopera ingagwiritsidwe ntchito popanga zambiri

Zitsulo zimayikidwa mumtsuko wa 10% mpaka 20% (ndi voliyumu) ​​sulfuric acid solution pa kutentha kwa 40 ° C.Kusintha kwa pickling solution kumakhala kofunikira ngati chitsulo chachuluka kuposa 80g/L ndipo ferrous sulfate iposa 215g/L mu yankho.

Kutentha kwachipinda,pickling zitsulondi 20% mpaka 80% (voliyumu) ​​hydrochloric acid yankho ndi zochepa sachedwa dzimbiri ndi embrittlement haidrojeni.
Chifukwa cha kuwonongeka kwa zidulo kwa zitsulo, ma corrosion inhibitors amayambitsidwa.Pambuyo poyeretsa, pamwamba pazitsulo zimawoneka zoyera ngati siliva, zomwe zimadutsa nthawi imodzi kuti ziwonjezere kukana kwa chitsulo chosapanga dzimbiri.

Khulupirirani kuti kufotokoza uku kumakhala kothandiza.Ngati mafunso ena abuka, chonde musazengereze kulumikizana.
