US 2026/0183745 A1 · SUPERABSORBENT POLYMER AND METHOD OF FORMING THE SAME

Abstract

A superabsorbent polymer and a method of forming the same are provided. The method includes performing a free radical polymerization reaction to a superabsorbent polymer component to obtain a colloid gel. The colloid gel is sheared by using a pulverizer to obtain superabsorbent polymer particles. A blade and a perforated plate are disposed at an outlet of the pulverizer, in which a section of the blade is a parallelogram, and the perforated plate has several holes. The method further includes performing a surface crosslinking reaction to the superabsorbent polymer particles to obtain the superabsorbent polymer. Therefore, a surface porosity, an absorption rate and a liquid conductivity of the obtained superabsorbent polymer can be increased.
