Corrosive effect of Farmic and Acetic acid on Ferrous metal andPrevention by VCIs

  Shailendra Kumar Dwivedi

Corrosive Effect of Formic and Acetic acid on Ferrous have been observed from very long time .Most of electronic and electrical assemblies are packed in wooden boxes. It get failure on coming time due rust formation in ferrous materials because most of wood emitted vapors’ of acid (Acetic and Formic acids) which accelerate the rust formation in different time duration at different RH, varies from 20% to 100%.Woods are generally made up of polysaccharides e.g hemicelluloses, xylan etc acetyl group attached to hemicelluloses which on hydrolysis gives acetic acid these vapors derived from acetyl group. Wood are mainly used in packaging materials. On degradation ,they gives acetic acid and carbonic acid vapors which corrode iron and other material which packed inside the box.(meduka indica) common name mahua wood exhalation has been studied for their corrosive behavior of mild steel.Corrosion rate of iron increased with in crease in the concentration of acetic acid

Keywords- hemicelluloses, wood exhalation, degradation, meduka indica, ferrous
