The swelling capacity of a polymer is determined by the amount of liquid material that can be absorbed. This test can done by two methods: # Beaker test method # Tea bag test method == Beaker test method == In this method * A small amount of superabsorbent polymer material is taken (0.1g) and it is placed in the beaker. * 100 ml of deionized water is poured into the beaker. * After 20 min the swollen polymer was separated by using filter paper * By weighing the polymer, one can find the swollen capacity of the SAP material. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「swelling capacity」の詳細全文を読む スポンサード リンク
