二氧化氯体系中碳钢缓蚀剂的研制及性能研究

研制了一种二氧化氯体系中的碳钢缓蚀剂。用静态失重法、电化学方法研究了A。3在质量分数为200×10^-6二氧化氯溶液中的电化学性能及加入缓蚀剂后对A3钢的缓蚀作用。几种研究方法结果一致表明：0．20g的GL与0．15mL的HEDP复配能使A3钢腐蚀率降低，腐蚀程度从重度腐蚀减轻到轻度腐蚀。此复配缓蚀剂的研究，对于碳钢在二氧化氯体系中的应用具有实际价值。

Preparation of carbon steel inhibitor in chlorine dioxide system and its property investigation

A carbon steel inhibitor in chlorine dioxide system was developed. The electrochemical properties of A_3 steel in chlorine dioxide solution (with chlorine dioxide mass fraction of 200×10~(-6)) and the inhibiting ability of inhibitor to the A_3 steel were investigated by static weight-loss measurement and electrochemical methods. Results show that the combination of 0.20 g GL and 0.15 mL HEDP can reduce the corrosive rates of A_3 steel, and corrosion degree is reduced from heavy corrosion to mildly corrosion. The research in inhibitor has actual value for A_3 steel used in chloride dioxide system.
