PESA has good scale inhibition and dispersion performance on calcium carbonate, calcium sulfate and barium sulfate in water, and its scale inhibition effect is better than that of common organophosphonic scale inhibitors. PESA has a good synergistic effect when compounded with phosphonates, and has a certain corrosion inhibition effect, so it is a multi-component scale inhibitor. PESA has good biodegradability, wide application range, especially suitable for cooling water systems under high alkali, high hardness and high pH conditions, and can realize operation with high concentration cycles; it has good compatibility with chlorine and good compatibility with other agents.
