用水蒸气-蒸馏法从樟树叶中提取桉叶油;并将其作为盐酸酸洗缓蚀剂的主要成分,用正交实验法优选了复合缓蚀剂配方;采用线性极化法评价缓蚀剂的缓蚀效率,并对其缓蚀机理进行了初步探讨.结果表明,复配缓蚀剂对碳钢在5%的盐酸溶液中有良好的缓蚀效果,属于混合控制型缓蚀剂.
Eucalyptus oil was extracted from the leaves of camphor tree by water vapor-distillation. The compound was used as the main component of hydrochloric acid pickling inhibitor. The compound corrosion inhibitor formulation was optimized by orthogonal experiment. , And the corrosion inhibition mechanism was discussed.The results showed that the compound corrosion inhibitor had a good corrosion inhibition effect on carbon steel in 5% hydrochloric acid solution and was a mixed controlled corrosion inhibitor.
