Article Preview

The influence of three kinds of biocide, sodium hypochlorite, dodecyl dimethyl benzyl ammonium bromide and isothiazolinone on the anti-corrosion performance of TP304 stainless steel in cooling water was studied by anodic passivation curves in this paper. The results showed that the sodium hypochlorite with the concentration above 10mg/L or the dodecyl dimethyl benzyl ammonium bromide with the concentration above 100mg/L may increase the pitting corrosion sensibility of the stainless steel in the cooling water, and the erosiveness of the cooling water to the stainless steel will increase as time goes by. Isothiazolinone with different concentrations did not influence the polarization curves of stainless steel, which indicated that isothiazolinone is a kind of safe biocide for stainless steel condensers.
