在印染工业中大量使用还原兰(RSN)。我厂为了满足国内市场的需要,于1971年建成生产还原兰及其原料2-氯蒽醌的车间。分解锅搅拌器是生产2-氯蒽醌的主体设备,而该搅拌器的腐蚀问题一直未得到解决。 分解锅是容积为4000升的钢制反应罐。反应介质(有机溶剂一氯化苯及稀盐酸和稀硫酸)对钢制容器的腐蚀速度很快,必须采取严格的防腐蚀措施方能维持正常生产。由
In the printing and dyeing industry extensive use of reduction blue (RSN). I plant in order to meet the needs of the domestic market, built in 1971 to restore the production of raw materials and 2-chloro-anthraquinone workshop. Decomposition pot mixer is the main production of 2-chloroanthraquinone equipment, and the blender corrosion problems have not been solved. Decomposition pot is a volume of 4000 liters of steel reaction tank. The reaction medium (organic solvent monochlorobenzene and dilute hydrochloric acid and dilute sulfuric acid) corrosion of steel containers fast, strict anti-corrosion measures must be taken to maintain normal production. by
