Research on Corrosion and Scale Inhibition Performance of HEDP

Abstract:

The static scale inhibition method will be used to evaluate the scale inhibition performance of HEDP. In order to study the corrosion inhibition of 20A steel with additive of HEDP in the industrial boiler water medium，the total iron ions in the solution are determined through autoclave static experiments. The results indicated that the scale inhibition efficiency，in the simulation boiler water with a certain concentration ratio and temperature，reached the maximum when CHEDP is 7 mg/L. It has a good corrosion inhibition effect on the 20A steel when the HEDP concentration exceeds 15ppm.
