摘要
A new non-phosphorus composite water treatment agent m(PASP) : m(PESA) : m(HPMA) : m(BTA) = 8:12:10:5 was developed from polyaspartic acid (PASP), polyepoxysuccinic acid (PESA), hydrolyzed polymaleic anhydride (HPMA) and benzotriazole (BTA). The performance of corrosion and scale inhibition were evaluated by rotary hanging-piece, electrochemical and bubble experiments. The corrosion testing piece was characterized by SEM. The results show that the new environment-friendly composite water treatment agent has good performance of corrosion and scale inhibition. Further dynamic simulated test also indicates that the water treatment agent meet the use demand of circulating cooling water.
