| 摘 要： | 提出了一种以乌洛托品、脂肪胺聚氧乙烯醚、十二烷基硫酸钠、0P-10乳化剂等为主要成份的盐酸缓蚀剂配方的一种高效复合型缓蚀剂，并研究了缓蚀剂添加量和温度对其缓蚀效果的影响，以及该缓蚀剂对废酸回收的影响.结果表明,该缓蚀剂的缓蚀率可以达到90%以上，控制合适的缓蚀剂添加量对废酸回收不会产生严重影响，适合大型钢板连续酸洗生产线使用.

| Abstract: | The efficiency for suppresing acid fogging and corrosion inhibition of iron during pickling process of iron in hydrochloric acid is studied by means of addition of agents such as urotropine, Dye Leveller AN, sodium dodecyl sulfate, OP-10 and so on. The influence of temperature and concentration of corrosion inhibitor in the pickling bath were studied. It is focused on influence of inhibitor on recovery of waste hydrochloric acid by roasting. In practical application, the efficiency of corrosion inhibition reaches ninety percent and the influences of inhibitor on recovery of waste hydrochloric acid by roasting is very little. |

| Keywords: | acid pickling of iron corrosion inhibitor roasting recovery of waste acid |
