Studied in the formula of compound corrosion inhibitor in cycling softened water

A new corrosion inhibitor compound formula was studied by means of addition of agents such as sodium nitrite,trisodium phosphate,benzotriazole and so on.The influence of Benzotriazole(BTA)by adding the amount,mass concentration of corrosion inhibitor and temperature were studied.The results show that the corrosion inhibitor in softened water using a temperature of 10~65℃ and the mass concentration of 100mg/L,the corrosion inhibition effect is excellent.
