摘要
采用苦参提取物作为植物型缓蚀剂,通过钢在不同缓蚀剂浓度、反应温度、盐酸浓度、反应时间条件下的单因素实验结果,设计了主要影响因子的正交实验,筛选出了最佳缓蚀条件.从红外光谱分析看,苦参缓蚀剂所含化合物分子中的O、N原子具有孤对电子,是良好的螯合配位体,可以与Fe的空d轨道形成配位键,发生化学吸附,使钢表面形成良好的缓蚀剂吸附膜层,起到了良好的缓蚀作用.
An orthogonal experiment is designed to screen out best inhibition condition by using the result of single factor experiments on inhibitor concentration,temperature,acid concentration and immersion time with the solid extractive from Sophora flavescens as inhibitor.The result of infrared spectroscopic analysis indicates that the O and N atoms in the compound molecule of Sophora flavescens inhibitor have one pair electrons,which are good chelation ligand and can form coordinate bond with the empty d track of Fe.And thus there occurs chemical adsorption,forming a good adsorption layer on the surface of the steel which produces excellent inhibitive effect.
