摘要

研究铜氨络合物对二乙基羟胺除氧效率的催化作用,及其复配物对碳钢的缓蚀保护能力.考察铜氨络合物添加量、水的pH值和温度对二乙基羟胺除氧性能的影响.除氧测试结果表明,二乙基羟胺的除氧率随着水的pH值和温度的增加而增加.添加铜氨络合物后,二乙基羟胺的除氧效果得到很大提升.铜氨络合物最佳添加质量浓度为8 mg/L.在此条件下,当水的pH≥7或水温为30~70 ℃时,二乙基羟胺的除氧率均能达到95%以上.缓蚀测试结果表明,铜氨络合物可显著提高二乙基羟胺对碳钢的防腐蚀保护能力,缓蚀率能达到96.2%,且缓蚀能力具有长效性.因此,铜氨络合物和二乙基羟胺的复配物具有很好的除氧缓蚀性能,在工业用水的除氧和工业碳钢设备的防腐蚀保护领域具有广阔的应用前景.

Abstract

The catalytic effect of copper-ammonia complex on the deoxygenation efficiency of diethylhydroxylamine (DEHA) and the corrosion protection ability of the compound on carbon steel are studied. The effects of the addition of catalyst, and the pH and temperature of water on the deoxygenation performance of DEHA are investigated. The results of the deoxygenation test show that the deoxygenation rate of DEHA increases with the increase of the pH and temperature of water. The deoxygenation effect is greatly improved after the addition of catalyst. The optimal concentration of copper ammonia complex is 8 mg/L. Under these conditions, when the water pH≥7 or the water temperature is in the range of 30 ℃ and 70 ℃, the oxygen removal rate can reach more than 95%. The corrosion inhibition test results show that the copper-ammonia complex can significantly improve the corrosion protection ability of DEHA to carbon steel, and the corrosion inhibition rate can reach 96.2% with a long-term effect. Therefore, the compound has a good deoxygenation and corrosion inhibition performance, which has broad application prospects in the field of deoxygenation of industrial water and corrosion protection of industrial carbon steel equipment.

Key words： copper-ammonia complex; diethylhydroxylamine (DEHA); deoxygenation; corrosion inhibition
