Apickling njira ndi ndondomeko mwatsatanetsatane zitsulo zitsulo chitoliro

1. Mwatsatanetsatane chitsulo chosakanizidwa chitoliro pickling ndondomeko

Mwatsatanetsatane zitsulo zosokonekera zitsulo chitoliro pickling njira makamaka zikuphatikizapo impregnated asidi kutsuka njira, utsi asidi kutsuka njira ndi asidi phala kuchotsa dzimbiri njira. mu 10% ~ 20% (volume) sulfuric acid solution pa kutentha kwa 40 C. Pamene njira yothetsera chitsulo iposa 80g / L ndi ferrous sulfate iposa 215g / L, mafuta odzola asidi ayenera kusinthidwa.Pa kutentha, ndi 20. % ~ 80% (volume) ya hydrochloric acid solution ya pickling zitsulo, sizovuta kuti zichitike dzimbiri ndi hydrogen brittle phenomenon.Chifukwa cha kuwononga kwakukulu kwa asidi pazitsulo, corrosion inhibitor imawonjezedwa. Pambuyo poyeretsa, chitsulo pamwamba chimakhala choyera chasiliva. , ndi passivate pamwamba kuti kukana dzimbiri zitsulo zosapanga dzimbiri.

Pofuna kuthetsa adsorption pamwamba ndi kuchepetsa chromatographic pachimake kuukoka mchira, chonyamulira ayenera kuchitiridwa ndi asidi kusamba kapena alkali kusamba pamaso ntchito. , zosefedwa, kutsukidwa kuti asalowerere, ndi zouma.Kutsuka kwa asidi kumatha kuchotsa chitsulo, aluminiyamu, calcium, magnesium ndi zonyansa zina patebulo, koma sangathe kuchotsa gulu la mowa wa silicone.

2.The zotsatira za yeniyeni zitsulo zitsulo pickling pickling

Chotsani mafuta ndi dzimbiri la chitoliro chachitsulo chosasunthika bwino kuti mukonzekere ndondomeko yotsatira.Mukapangidwe kameneka, njira yopangira pickling ndiyo kuchotsa khungu la okosijeni, pambuyo pa mankhwala odzola (mpweya zitsulo-phosphorous saponification, zitsulo zosapanga dzimbiri-mafuta a laimu, chitoliro cha aluminiyamu yamkuwa, chitoliro cha aluminiyamu yamkuwa. -mafuta), ndi ndondomeko yakale-mkuwa plating), ndiyeno m'zigawo ndi processing kwambiri.Ngati chitsulo chitoliro si pickling, pakhoza kukhala okusayidi ndi mafuta padziko.Kuipitsa, phosphoride madzi mphamvu nyukiliya sangathe kuwachotsa, phosphorization khalidwe adzakhala yafupika.
