中文摘要:
      目的 合成增甘膦,研究增甘膦及其复配液缓蚀性能。 方法 以亚磷酸、甲醛、甘氨酸为原料,在酸性条件下,合成增甘膦。 通过塔菲尔曲线法和电化学阻抗谱,测试酸性条件下 LY12 硬铝在增甘膦溶液中的缓蚀性能,并与同类有机膦系缓蚀剂氨基三甲叉膦酸(ATMP)进行比较。 同时,在碱性条件下,测试 LY12 硬铝在增甘膦复配液中的缓蚀性能。 结果 当 pH=1,增甘膦缓蚀液质量分数为 0. 5% 时,缓蚀率可达 90% 。 在相同酸性条件及缓蚀剂含量下,增甘膦缓蚀效果较 ATMP 好。 在碱性条件下,增甘膦单独使用缓蚀效果不佳,与三乙醇胺复配后缓蚀效果较好。 当增甘膦与三乙醇胺复配含量为 0. 5% (质量分数)三乙醇胺+0. 4% (质量分数)增甘膦时,LY12 硬铝在 pH= 8. 7 体系中的缓蚀率为 65. 5% 。 结论增甘膦单独使用,在酸性条件下有很好的缓蚀效果;与三乙醇胺复配后,在碱性条件下也有较好的缓蚀效果。
英文摘要:
      Objective To synthesize glyphosine and study the corrosion inhibition performance of glyphosine and its mixture. Methods Glyphosize was synthesized with phosphate, formaldehyde and glycine in acidic solution. The corrosion inhibition performance of LY12 alloy in glyphosine solution under acidic condition was studied by Tafel curves and electrochemical impedance spectroscopy. And glyphosine was compared with the similar phosphonic acid, i. e. , amino trimethylene phosphonic acid (ATMP). Besides, the corrosion inhibition performance of LY12 alloy was studied in glyphosine solution. Results When the pH=1, the mass concentration of glyphosine was 0. 5% , the corrosion inhibition rate was up to 90% . And the corrosion inhibition effect of glyphosine solution was superior to ATMP under the same acidity and the same concentration of corrosion inhibitor. The corrosion inhibition effect of glyphosine was not ideal while used alone in alkaline condition. However, when it was mixed with trolamine, the corrosion inhibition effect was preferable. When the pH = 8. 7 and the built-up concentration was 0. 5% trolamine with 0. 4% glyphosine, the corrosion inhibition rate of LY12 alloy was up to 65. 5% . Conclusion The corrosion inhibition effect of glyphosine was excellent when used alone under acidic condition. Its corrosion inhibition effect was preferable when it was mixed with trolamine under alkaline condition.
