The effect on scale inhibiting property of the product from amount and feed times of catalyst, the reaction temperature, the reaction time were investigated. The optimum reaction conditions are as follows: 1 18 g catalyst, 95 ℃ and 3 hours of synthesis.展开更多

In addition, the synergistic effect among PESA, Zn 2+ and sodium gluconate was also investigated. According to the experimental data, when only PESA is used, it had fairly good effect on steel. The synergy between PESA and Zn 2+ or sodium gluconate was poor. However, the synergistic effect of PESA, Zn 2+ and sodium gluconate is very good. Further experiments show that the corrosion inhibition of PESA is mainly affected by oxygen atom inserted.展开更多
