Synthesis of Polyaspartic Acid Composite and its Application in Magnetic Water

In order to increase the general scale inhibition rate of PASP, a new PASP composite was prepared from PASP, IA-AA-AE and PBTCA, and it was synergized by a magnetic field, which showed high scale inhibition performance, especially in high-hardness water. Under Ca
²⁺
ion 650 mg/L, the scale inhibition rate of PASP composite in magnetic water can increase to 75.9 %, which is 12 % higher than that of PASP composite.
