Corrosion Activity of Low-Carbon Steel Under the Action of Multi-Component Anti-Icing Reagent

Abstract

Corrosion activity of a multi-component solution, namely, distiller liquid previously clarified and strengthened to 20 wt% by CaCl₂ including the addition of corrosion inhibitors at –5°C to low-carbon 08kp steel is studied by the gravimetric method. The holding time of the specimens is 500–650 h. In distiller liquid corrosion rate is 0.111 g/(m²×h), corrosion depth is 0.12 mm/year, steel resistance refers to the IV group (relatively resistant). When adding the hexamethylenetetramine, triethanolamine, trilon B corrosion inhibitors or their mixture in the amount of 0.5 wt% the corrosion resistance of steel improves, and the best results are achieved by adding hexamethylenetetramine with triethanolamine. The obtained results indicate the possibility of using the distiller liquid from sludge accumulator of JSC “Lysychanska Soda” with additives of such corrosion inhibitors as reagents for preventing highway surface against icing.
