Corrosion Characteristics of Soldered Sideseam Tinplate and Welded Sideseam ECCS Plate Cans Using Organic Acid Model Systems
HARDY, K.M. | DAVIS, D.R.
A model system of six organic acids and water was prepared using two pH ranges and two nitrate levels and packed in soldered sideseam tinplate and welded sideseam enameled cans. Can vacuum, Fe and Pb content were determined after 8‐months storage at room temperature and at 38°C. The ECCS plate cans had lower can vacuums and lower solution Fe content than the tinplate cans. Polygalacturonic acid (PGA) was an aggressive corrosive agent in both can types. Water, PGA and malic acid solutions contained the highest concentrations of Pb.
