Abstract:

Polarization techniques are used for testing the impact of different compounds (additives) on tinplate corrosion, using pieces of apricot dipped in syrup with and without nitrate addition as electrolyte solution, at the same time using filled cans as electrolytic cell and operating electrode. This procedure determined the intensity of inhibiting tin dissolving with some of the used additives like sodium-benzoate, potassium-sorbate sodium-lauril-sulphate and p-aminobenzoate acid.

Abstract:

This paper presents the results of examination of the corrosion behaviour of electrolytic tinplate in model solutions of salts in liquid contents (fills) of peas and string beans tins. The tins have been stored at the temperature of 25°C during the period of 18 months. The obtained results show that the corrosion currents and consequently corrosion rates, too, have higher values in the liquid contents (fills) of the tins than in the pure model solutions.
