Abstract
The issue study the corrosion with fog effects of the hydrochloric acid lotion, with added solvents such as OP,SDS and TU on silicon steel. We make out a series of experimental schemes to choose the best formulation of additives in mixed fog inhibitor and compared it’s changes in different pickling time, different pickling temperatures and different concertration of hydrochloric acid.We also studied on whether an inhibitor influences the pickling quality by contrast tests.The results showed that the best formulation is the mix of 1.2%OP and 0.004%SDS.This inhibitor has a high inhibition of acid fog, The distribution of fog inhibitor in 40℃,the best mist suppression rate was 29.03%; In 12% concentration of hydrochloric acid, the best mist suppression rate was 26.82%; In 19℃, the best corrosion rate was 89.43%; In 9% hydrochloric acid concentration, the best corrosion rate was 76.55%, the fog inhibitor added to HCl doesn’t affect the quality of iron oxide red.
Key Words: Silicon steel；pickling；inhibitor；corrosion inhibition efficiency；iron oxide red
