采用失重法研究了糠醛对碳钢的缓蚀性能。实验表明30 ℃,4 h条件下,在5% 的盐酸中,糠醛具有较强的缓蚀作用,与六次甲基四胺复配缓蚀效果增强。通过研究找到了糠醛在碳钢上的吸附等温式,计算出碳钢溶解的表观活化能,研究了糠醛在碳钢上的吸附机理。研究表明糠醛为混合控制型缓蚀剂。
The corrosion inhibition effect of furfural on the carbon steel was studied by weightloss method. It was shown that the furfural had strong corrosion inhibition effect on carbon steel in 5% HCl solution at 30 ℃. A strong synergistic effect was observed while using both furfural and sexamethyltetraamine as inhibitors. The inhibition mechanism was discussed by the authors.
