Ubuchwephesha obusetyenzisiweyo ukuphelisa ulusu lwe-oxide kunye nomhlwa kumphezulu wentsimbi ukusuka kumphezulu wentsimbi kunye nentsimbi, kusetyenziswa izisombululo ezine-asidi, kuchazwa njengokukhetha.
I-iron oxides ezifana ne-oxide scale kunye ne-rust (Fe3O4, Fe2O3, FeO, njl.) ifumana ukuphendulwa kweekhemikhali kunye nezisombululo ze-asidi, zenze iityuwa ezinyibilikayo kwisisombululo se-asidi kwaye zisuswe.
zingene kwi-chemical reaction kunye nezisombululo ezine-asidi, ezikhokelela ekwenziweni kweetyuwa ezinyibilikayo ezithi emva koko zikhutshwe.I-Acids kwinkqubo yokuchola ibandakanya i-sulfuric acid, i-hydrochloric acid, i-phosphoric acid, i-nitric acid, i-chromic acid, i-hydrofluoric acid, kunye ne-asidi edibeneyo.Ngokuqhelekileyo, i-asidi ye-sulfuric kunye ne-hydrochloric acid zikhetho ezithandwayo.Iindlela zokuchola zibandakanya ukunyuswa kokuntywiliselwa, ukucholwa kokutshizwa, kunye nokususwa kwerusi intlama yeasidi.

Ngokuqhelekileyo, ukunyuswa kokuntywiliselwa kusetyenziswa ngokuqhelekileyo, kwaye indlela yokutshiza ingasetyenziselwa imveliso yobuninzi

Amalungu entsimbi alawulwa ngokwesiqhelo kwi-pickling kwi-10% ukuya kwi-20% (ngokomthamo) isisombululo se-sulfuric acid kubushushu bokusebenza obungama-40°C.Ukutshintshwa kwesisombululo se-pickling kuyimfuneko xa umxholo wesinyithi udlula i-80g / L kunye ne-ferrous sulfate idlula i-215g / L kwisisombululo.

Kwiqondo lobushushu legumbi,intsimbi yokukhakunye ne-20% ukuya kwi-80% (umthamo) isisombululo se-hydrochloric acid singaphantsi kwe-corrosion kunye ne-hydrogen embrittlement.
Ngenxa ye-corrosion proclivity ye-asidi ukuya kwisinyithi, ii-corrosion inhibitors ziye zaziswa.Ukucoca emva kokucoca, umphezulu wesinyithi ubonisa imbonakalo yesilivere-emhlophe, ngexesha elifanayo idlula i-passivation yokwandisa iimpawu zokumelana ne-corrosion yensimbi engenasici.
