Then, the measurement methods of these parameters were reviewed, such as measuring water absorption ratio and water absorption velocity by natural filtering method and tea-bag method, measuring water retention ratio under pressure, temperature and natural conditions. Lastly, in order to compare the functions of super-absorbent resin which prepared by different manufacturers, the advice-formulating unified standards and measurement methods was also emphasized.
