Abstract

In this article, the scale and corrosion inhibition performances of Polyaspartic acid (PASP) and PASP-based composite were studied. The results showed the single PASP has good scale and corrosion inhibition performances, but the quantity of PASP used for corrosion inhibition is large (100mg/L). To reduce cost, PASP-based composite was prepared from PASP, BTA, sodium tungstate and sodium gluconate with different scales. The optimal proportioning mass ratio is as follows: PASP : BTA : sodium tungstate : sodium gluconate is 10 : 0.5 : 20 : 10 (total concentration: 40.5 mg/L). Experimental results showed the corrosion rate of HSn-70A copper is only 0.0006 mm/a and corresponding corrosion inhibiting rate reaches 99.22%. The small dynamic simulation showed that inhibition rate of this PASP-based composite can reach more than 90% even in high hardness and concentration.
