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

Static and dynamic experiments were used to evaluate scale inhibition performance of modified polyaspartic acid (PASP-ASP). The static experiments showed that the PASP-ASP had good scale inhibition performance and the scale inhibition rate exceeded 98% when the PASP-ASP was 2 mg·L-1 and the solution temperature was 40 OC. In the dynamic experiments, almost no scale was formed on the heat transfer surface and the fouling thermal resistance decreases extraordinarily with PASP-ASP treatment experiment compared with the experiment without treatment. The PASP-ASP could be used in industrial cooling water systems.
