对影响氯乙烯转化器反应管外表面的腐蚀现象的因素进行了讨论 ,认为在氯乙烯转化器的循环冷却水介质中 ,氯离子浓度、pH值、温度和压力及它们之间的协同效应是影响腐蚀的主要因素 ,在循环冷却水介质中加入DYJ— 1型复合缓蚀剂可获得良好的缓蚀效果 .
The factors influencing the corrosion of the outer surface of the reaction tube of the vinyl chloride converter are discussed. It is considered that the chloride ion concentration, the pH value, the temperature and the pressure and the synergistic effect among them in the circulating cooling water medium of the vinyl chloride converter are Affect the corrosion of the main factors in the circulating cooling water medium by adding DYJ-1-type composite corrosion inhibitor can obtain good corrosion inhibition.
