OXIME CONTAINING INHIBITORS FOR ACID PICKLING

摘要

A combination of (i) oximes and (ii) non-carcinogenic and low toxicity amines and/or quaternary ammonium salts provides effective pickling inhibition. The addition of surfactant materials containing at least one polyoxyalkylene moiety per molecule substantially reduces any tendency that the working pickling compositions containing this inhibitor combination might otherwise have to form undesirable tarry materials that can contaminate the pickled surfaces.
