摘要
通过对缓蚀剂用量、不同温度及不同材质的腐蚀速率等的测试 ,研究了IS 136缓蚀剂在EDTA清洗中的性能。结果表明 ,IS 136是一种性能优异的EDTA清洗缓蚀剂 ,135℃时对 2 0A钢和低合金钢的腐蚀速率≤ 5g/m2 ·h ,实际应用也证明 ,可完全满足电厂大容量锅炉EDTA清洗的要求。
The performance of IS 136 corrosion inhibitor for EDTA pickling was studied by surveying the corrosion rate under different inhibitor concentration, diffrent temperature and different materials,et al.The results showed that the inhibitor IS 136 was a excellent corrosion inhibito for EDTA pickling which corrosion rate on 20A carbon steel and low alloy steel was less than 5 g/m 2·h and their inhibition efficiecies were more than 95% at about 135 ℃.The application in industry also demonstrated that the inhbitor IS 136 could be fully adequate to meet the demand of EDTA picklng for the large steam boiler in power plant.
