AN ACID FOGGING SUPPERSION AND CORROSION INHIBITION FORPICKLING PROCESS OF IRON IN HYDROCHLORIC ACID

The efficiency for suppresing acid fogging and corrosion inhibition of iron during pickling process of iron in hydrochloric acid is studied by means of addition of agents such as urotropine and Dodecyl sulfonlc acid sodiumsalt and LH etc.By comparatively studing the efficiency of additives singly or compositely,and the influence of temperature and HCl concetration of the pickling bath,the optional formulation of the hydrochloric acid pickling solution is acquired.
