Study on Scale Inhibition Performance of Polyaspartic Acid Derivatives with Dihydroxyl Group on CaCO3

Abstract:

Article Preview

An environment-friendly and multifunctional agent for industry circulation cooling water, polyaspartic acid derivatives with dihydroxyl group(DHPAP) was synthesized in aqueous solution. The FTIR spectrum of DHPAP was analyzed. Static experiments were carried out to validate scale inhibition performance of DHPAP. The scale inhibition ratios exceed 90% when 8 and 10 mg/L DHPAP under solution temperatures of 80 and 60°C, respectively. The scale inhibition ratios increase by increasing the DHPAP concentration with 6 and 8 mg/L under heating times of 10 and 6h, respectively. And the scale inhibition ratios are over 90%.
