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.
