METHOD FOR MEASURING FRACTURE STRENGTH OF SUPERABSORBENT POLYMER SINGLE PARTICLE

摘要

A method of measuring fracture strength of a superabsorbent polymer in order to predict a generation amount of fine powder is provided. Effects of many different treatments for increasing strength of the superabsorbent polymer may be evaluated by measuring a force at a time point when single particles having a uniform particle size of the superabsorbent polymer are fractured by pressurizing the particles at a constant rate within a predetermined range.
