摘要 

采用静态失重法首先研究了聚环氧琥珀酸(PESA)、聚天冬氨酸(PASP)和葡萄糖酸钠(Glu)三种单组分缓蚀剂对碳钢的缓蚀性能,然后将三者进行正交复配,得到一种缓蚀效果优良的新型无磷复合型缓蚀剂PESA/PASP/Glu。研究了不同因素对其缓蚀性能的影响,结果表明:该复合缓蚀剂的最佳适用浓度为1000 mg?L-1,此时缓蚀率达到94.6%;其缓蚀率随时间的延长逐渐下降,48 h时依然维持在70%以上;随温度的升高稍有降低,80℃时仍然能达到86.5%;随pH的增加而上升,在pH 为12时缓蚀率可达到96.5%,几乎完全抑制碳钢的腐蚀。该复合药剂是一种尤其适用于高温、高碱环境下的无磷缓蚀剂。

Abstract: 

The corrosion inhibition performances of three single-component corrosion inhibitors of polyepoxysuccinic acid (PESA), polyaspartic acid (PASP) and sodium gluconate (Glu) for carbon steel were tested by the static weightlessness method. Then the three agents were combined with each other in an orthogonal way to form a composite inhibitor of PESA/PASP/Glu with a high corrosion inhibition performance on carbon steel. Finally, the effects of the addition concentration, test the time, temperature and pH on the corrosion inhibition of the composite agents were investigated. The composite agents showed a corossion inhibition rate of 94.6% under the optimal concentration of 1000 mg?L-1. The corrosion inhibition rate decreased gradually with time but remained above 70% at 48 h. With temperature increased, the corrosion inhibition rate reduced slightly and still reached 86.5% at 80℃. Higher corrosion inhibition rate was found at higher solution pH. The corrosion inhibition rate is 96.5% at pH 12, almost completely inhibiting the corrosion of carbon steel. These results indicated that the phosphorus-free composite corrosion inhibitor was especially suitable for high temperature and high alkalinity system.
