Inhibition Performance

Static and dynamic experiments were used to evaluate scale inhibition performance of polyaspartic acid derivative (PASP-SEA-ASP). The static experiments showed that the PASP-SEA-ASP had good scale inhibition performance and the scale inhibition rate exceeded 80% when the PASP-SEA-ASP was 2 mg•L-1 and the solution temperature was 40 OC. In the dynamic experiments, almost no scale formed on the heat transfer surface and the fouling thermal resistance decreases extraordinarily with PASP-SEA-ASP treatment experiment compared with the experiment without treatment. The PASP-SEA-ASP could be used in industrial cooling water systems.

Inhibition Performance

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%.
