Description

technical field

[0001] The invention relates to a synergistic corrosion inhibitor, in particular to a ternary synergistic corrosion inhibitor containing polyaspartic acid for cooling water treatment and waste water treatment. Background technique

[0002] The synergistic effect of corrosion inhibitors means that when the amount of corrosion inhibitors is the same, with the appropriate mixture of corrosion inhibitors, the corrosion inhibition effect is obviously higher than that of each component used alone. As early as the early 1950s, the synergistic effect of corrosion inhibitors had been discovered and became the main basis for the research of corrosion inhibitors and the development of modern commercial corrosion inhibitors. However, until now, the nature and regularity of the synergistic effect of corrosion inhibition are far from being ascertained, and the development of composite corrosion inhibitors is basically empirical. Take the newly developed corrosion inhibito...
