摘要
讨论了用过硫酸铵作引发剂,糊化温度与时间以及预氧化温度与时间对淀粉接枝聚丙烯酸高吸水性树脂吸水能力的影响。实验结果表明,前处理工艺条件为:糊化温度85 ℃,糊化时间20 min,预氧化时间10 min,预氧化温度70 ℃。
This article has studied the effect of paste temperature and time or preoxidization temperature and time on water absorption of high absorbent resin by using ammonia persulfate as initiator. The experiment showed that the optimal condition of pre-conditioning was paste temperature 85℃, paste time 20 minutes, preoxidization temperature 70℃ and preoxidization time 10 minutes.
