摘要
通过对工业生产中大量的实际生产数据进行分析,总结出生产过程中控制产品色浅的合适条件为:选用特级松香原料,原料松香熔融时间5 h,熔融温度130~150℃,生产中松香流量控制在400L/h左右,反应温度控制在240~250℃之间.另外还应尽量减少反应系统中的CO、CO2、SO2、重金属离子的含量,避免有色油类和空气进入反应系统,最后对产品进行水蒸气蒸馏,能得到颜色较浅的氢化松香产品.
By analyzing a plenty of practical production data,suitable conditions for controlling the product color during the production of hydrogenated rosin are concluded to be super grade rosin as raw material,melting time 5h and melting temperature 130150,molten rosin flow rate 400L/h,reaction temperature 240250. Furthermore,as less CO,CO_2,SO_2,heavy metal ions,colored oil and air as possible ,and the final steam distillation are all favorable to produce lighter color hydrogenated rosin.
