Process for continuous production of water-absorbent resin product

摘要

There is disclosed a process for continuous production of a water-absorbent resin product by which the water-absorbent resin product having high properties can continuously be produced easily and inexpensively with stable constant quality. In addition, there is disclosed a water-absorbent resin product having high properties and being stable in quality. The process comprises a step of measuring a water-absorbent resin by its particle diameters, wherein the water-absorbent resin comes being continuously produced via a classification step and/or a surface-modifying step, wherein the aforementioned particle diameters of the water-absorbent resin are measured by a laser diffraction scattering method.
