- Abstract
Polyaspartic acid derivative (PASP-SEA-ASP) was prepared from polysuccinimide (PSI) that was thermal condensation polymer of aspartic acid (ASP), taurine (SEA) and ASP. The structure of polyaspartic acid derivative was characterized by means of FTIR. The property of scale inhibition of PASP-SEA-ASP by static experment and weight loss method for corrosion inhibition efficiency were studied. Calcium carbonate crystals in scale samples and corrosive test pieces were analysed by means of SEM. The results showed that under Ca2+ 400 mg/L, HCO3- 800 mg/L and polyaspartic acid derivative 4 mg/L, the scale inhibition rate of polyaspartic acid derivative can reach 67.42%. And it also possessed better corrosion inhibition performance and the corrosion inhibition rate can reach 67.53%. Measuring results of SEM showed that polyaspartic acid derivative could distort calcium carbonate crystallite and made calcium carbonate crystallite more dispersive. Measured by SEM, the test piece was immersed in solution with polyaspartic acid derivative has little pits on its surface. This study demonstrated the potential of PASP-SEA-ASP to inhibit both corrosion and scale formation in industrial circulating cooling water systems.
