Inhibition efficiency of BTA compound corrosion inhibitor

The main parameter of corrosion factor(Kp) that resulted in the corrosion of air coolers,was examined by preparing a simulated corrosive solution,and investgating experimentally the inhibition efficiency of organic corrosion inhibitor of benzotriazole(BTA) and its derivatives with the corrosion rate testing equipment of resistance probe.The results showed that there existed good synergistic effect between corrosion inhibitor of BTA and its derivatives,which reduced effectively the corrosion rate of metal surface.
