Title: NON-DESTRUCTIVE METHOD FOR EVALUATING STRUCTURE OF WATER-ABSORBING RESIN
Abstract:
Provided is a non-destructive method for evaluating the structure of a water-absorbing resin which can be advantageously used for controlling various properties of the water-absorbing resin. This non-destructive method for evaluating the structure of a water-absorbing resin involves non-destructively evaluating the structure of a water-absorbing resin through an X-ray computer tomographic technique, wherein the method comprises a step 1 for installing the water-absorbing resin to be evaluated on a test piece stage of an X-ray computer tomography device, a step 2 for performing X-ray computer tomography on the water-absorbing resin using the X-ray computer tomography device and acquiring tomographic image data of the water-absorbing resin, and a step 3 for analyzing the tomographic image data using image analysis software and obtaining a tomographic image of the water-absorbing resin.
