1. Inkqubo yokuchola umbhobho wentsimbi echanekileyo engenamthungo
Precision ingenamthungo intsimbi umbhobho pickling indlela ikakhulu ibandakanya ukufakwa asidi ukuhlamba indlela, ukutshiza indlela yokuhlamba iasidi kunye neasidi intlama umhlwa ukususwa indlela.Ngokuphangaleleyo, sisebenzisa indlela yokuhlanjwa acid efakiweyo, kwaye indlela yokutshiza ingasetyenziswa kwimveliso mass.Iinxalenye zentsimbi ngokubanzi pickling kwi-10% ~ 20% (umthamo) isisombululo se-sulfuric acid kwiqondo lokushisa lama-40 C.Xa isisombululo somxholo wentsimbi sidlula i-80g / L kunye ne-sulfate ye-ferrous idlula i-215g / L, i-asidi yokuthambisa kufuneka ithathelwe indawo.Kubushushu begumbi, kunye ne-20 I-% ~ 80% (umthamo) wesisombululo se-hydrochloric acid kwi-pickling yensimbi, akukho lula ukwenzeka i-corrosion kunye ne-hydrogen brittle phenomenon.Ngenxa yempembelelo enkulu ye-asidi kwintsimbi, i-corrosion inhibitor yongezwa.Emva kokucoca, indawo yesinyithi iba yisilivere emhlophe. , kwaye udlulise umphezulu wokuphucula ukuxhatshazwa kwe-corrosion yensimbi engenasici.
Ukuze kupheliswe i-adsorption yomhlaba kunye nokunciphisa i-chromatographic incopho yokutsala umsila, umphathiswa kufuneka aphathwe ngokuhlamba kwe-asidi okanye ukuhlamba i-alkali ngaphambi kokusetyenziswa.I-Apickling kukucwina umthuthi nge-6 mol / L i-hydrochloric acid ye-2h okanye i-hydrochloric acid egxininisiweyo ye-30min. , yahluzwa, ihlanjwe ukuba ingathathi hlangothi, kwaye yomiswe.Ukuhlamba i-Acid kunokususa isinyithi, i-aluminium, i-calcium, i-magnesium kunye nezinye izinto ezingcolileyo etafileni, kodwa ayikwazi ukususa iqela le-silicone yotywala.
2.Isiphumo sokucholwa kombhobho wentsimbi engenamthungo echanekileyo
Susa ioli kunye nomhlwa wombhobho wentsimbi echanekileyo ukuze ulungiselele inkqubo elandelayo.Kwinkqubo yokuvelisa, inkqubo yokuchola kukususa ulusu lwe-oxidation yomhlaba, emva konyango lokuthambisa (i-carbon steel-phosphorus saponification, i-stainless steel-bhotolo lime, umbhobho we-aluminium wobhedu. -oyile), kunye nenkqubo endala-i-plating yethusi), kwaye emva koko i-extraction and deep processing.Ukuba umbhobho wensimbi awukhethi, kunokubakho i-oxide kunye neoli phezu komhlaba.Ungcoliseko, ulwelo lwe-phosphoride amandla enyukliya alukwazi ukuwasusa, umgangatho we-phosphorization uya kuncitshiswa.
