Corrosion Inhibitor Polyepoxysuccinic Acid PESA 40% CAS No.51274-37-4 109578-44-11

Polyepoxysuccinic acid (PESA cas: 51274-37-4 109578-44-1) is a nitrogen free, non phosphorus organic compound with dual effects of scale and corrosion inhibition. It has good biodegradability and is suitable for high alkali and high metal content water systems. It is a green water treatment chemical. Scale inhibition performance of PESA; The experiment shows that PESA has a solubility limit effect on the deposition of calcium sulfate scale, and its scale inhibition rate increases with the increase of dosage. When it reaches a certain concentration, the scale inhibition ability no longer increases significantly. The effectiveness of PESA in inhibiting calcium carbonate scale is superior to some commonly used polycarboxylate acid, sulfonate, and polyphosphate scale inhibitors.Corrosion inhibition performance of PESA: When used alone, a lower dosage of PESA has a certain corrosion inhibition effect on carbon steel. As the concentration of PESA increases, its corrosion inhibition effect also strengthens, and the corrosion rate of carbon steel gradually decreases while the corrosion inhibition rate increases. To achieve a good corrosion inhibition effect, a high concentration of PESA is required. When PESA cas: 51274-37-4 109578-44-1 is used alone as a corrosion inhibitor, its performance is inferior to other organic phosphate corrosion inhibitors. However, because it does not contain phosphorus, it can be compounded with other agents to form low phosphorus or phosphate free phosphates, benzotriazoles, etc. It has a good synergistic effect, and the corrosion inhibition effect is significantly enhanced after compounding.
