Abstract
Official abstract text for this publication.
An object of the invention is to provide a technique in which a decrease in physical properties is suppressed or consumer complaints are diminished. A method for filling a particulate water absorbing agent includes a filling step of filling a particulate water absorbing agent into a filling container and a vibrating step of vibrating the filling container at the outside of the filling container, the vibrating step being conducted at least one time between the start and the end of the filling step, in which a vibration condition in the vibrating step satisfies the following conditions (a) and (b): (a) vibration by a vibrating body in contact with the filling container has a vertical directional component and a vibrational angle is within 90°±30°; and (b) total amplitude at no load and a vibration frequency at no load of the vibrating body are set so as to satisfy Equation 1-1 and Equation 2 or Equation 1-2 and Equation 2.

1 . A method for filling a particulate water absorbing agent, the method comprising: a filling step of filling a particulate water absorbing agent into a filling container, and a vibrating step of vibrating the filling container at the outside of the filling container, the vibrating step being conducted at least one time between the start and the end of the filling step, wherein a vibration condition in the vibrating step satisfies the following conditions (a) and (b): (a) vibration by a vibrating body in contact with the filling container has a vertical directional component and a vibrational angle is within 90°±30°; and (b) total amplitude at no load and a vibration frequency at no load of the vibrating body are set such that the following Equation 1-1 and Equation 2 or Equation 1-2 and Equation 2 are satisfied. [Mathematical Formula 1] 1≦acceleration (G)≦13 in a case in which final filling amount of particulate water absorbing agent per filling container: W 2≧100 kg (Equation 1-1) 1≦acceleration (G)≦15 in a case in which final filling amount of particulate water absorbing agent per filling container: W 2<100 kg (Equation 1-2) [Mathematical Formula 2] 27.0≦vibration index≦44.0 (Equation 2) Incidentally, the acceleration and the vibration index are values calculated by the following Equation 3 and Equation 4, respectively. [ Mathematical Formula 3 ] Acceleration [ G ] = total amplitude at no load [ mm ] × ( 2 π × vibration frequency at no load [ Hz ] ) 2 2 × 1000 × 9.8 ( Equation 3 ) [ Mathematical Formula 4 ] Vibration index = 42 - 0.29 × vibration
