文摘

Polyepoxysuccinic acid (PESA) is a new kind of biodegradable scale inhibitor. A scaling-corrosion inhibitor composed of modified PESA and imidazoline is manufactured. Compound prescriptions of water treatment agents are screened by rotary coupon corrosion test and static anti-scaling method, respectively. The optimal ratio of corrosion and scale inhibitor has been found, and experimental result shows that the sifted prescription has excellent performance of corrosion and scale inhibition.
