摘要:

影响苯乙烯产品聚合物的因素有存储时间、储存温度、罐内氧含量、苯乙烯产品pH值、苯乙烯产品TBC含量和内防腐涂料等,上述因素都可能引起苯乙烯产品质量出现问题,特别是储罐防腐涂层脱落,内壁存在亚铁离子。当液面超过脱落层时,苯乙烯与亚铁离子发生反应,形成聚合物,并溶解在苯乙烯中,导致苯乙烯产品中聚合物含量逐渐上升,此外影响苯乙烯储存质量的因素是多方面的,就聚合物含量而言,除了工艺操作、外界条件以外,施工质量和防腐材料的选择也很重要,需要从设计、施工、工艺等方面进行深入研究,不断地进行改进,保证苯乙烯产品储存质量。

Abstract:

The factors that affect the polymer of styrene products include storage time, storage temperature, oxygen content in tank, pH value of styrene products, TBC content of styrene products and internal anti-corrosion coatings. All of the above factors may cause problems in the quality of styrene products, especially the peeling of anti-corrosion coating and the existence of ferrous ion in inner wall. When the liquid level exceeds the coating that peeled off, styrene reacts with ferrous ion to form polymer, which is dissolved in styrene, resulting in the gradual increase in polymer content of styrene products. In addition, various factors affect the storage quality of styrene products. As for polymer content, besides process operation and external conditions, the construction quality and the selection of anti-corrosion materials are also very important. In order to ensure the storage quality of styrene products, it is necessary to conduct in-depth research and continuous improvement from the aspects of engineering, construction and technology.
