摘要： [PROBLEM]It is an object of the present invention to enhance and stabilize properties of a water-absorbing resin, for example, damage resistance or water-absorbing speed, by a simple and convenient method without requiring change of raw materials or expensive facility investment, in a large scale production method for the water-absorbing resin.[MEANS FOR SOLVING THE PROBLEM]It is solved by circulation of the water-absorbing resin in a predetermined amount or more in the pulverization step before the surface cross-linking step. That is, at least a part of the classified polymer is supplied again to the same or different pulverization step, before the surface cross-linking step, wherein circulation pulverization ratio in the pulverization step, represented by the following equation is 1.10 to 1.50: (Circulation pulverization ratio)=(total supply amount of the water-absorbing resin to the pulverization step)/(total discharge amount of the water-absorbing resin at the drying step) (wherein total supply amount of the water-absorbing resin to the pulverization step)=(total discharge amount of the water-absorbing resin at the drying step)+(amount of the classified polymer supplied again to the same or different pulverization step)).
摘要翻译：本发明的目的是通过简单方便的方法来增强和稳定吸水树脂的性能，例如耐损伤性或吸水速度，而不需要改变原料或昂贵的设备投资在大量的吸水树脂的制造方法中。解决问题的手段通过在表面交联工序之前的粉碎工序中使吸水性树脂循环一定量以上来解决。也就是说，在表面交联步骤之前，将分类的聚合物的至少一部分再次供给到相同或不同的粉碎步骤，其中由下式表示的粉碎步骤中的循环粉碎比为1.10至1.50：（循环粉碎比）=（粉碎步骤中的吸水性树脂的总供给量）/（干燥工序中的吸水性树脂的总排出量）（其中，吸水性树脂与粉碎的总供给量步骤）=（干燥步骤中的吸水性树脂的总排出量）+（再次供给相同或不同的粉碎步骤的分类聚合物的量））。
