Aquasorb Mechanism For Water-absorbent and Water retention

Aquasorb are electrolytes, and its absorption mechanism is different from the pulp, sponge, etc. of physical absorpting absorbent absorbent materials. Aquasorb is due to the absorbent polymer electrolyte ion exclusion caused by the molecular network structure, expansion and obstacles to the expansion of molecular interaction of the result. Polymers of the molecular chain of infinitely connected, between molecules was complex three-dimensional network structure, it has a certain degree of cross-linking. There are a number of carboxyl, hydroxyl and other hydrophilic groups Iin its cross-linked network structure , when it is in contact with water, its molecular surface of the hydrophilic group ionization and molecules together to form hydrogen bonds with the water , holding large amounts of water through suction.

In this process, the grid makes the electrolyte of the electrolyte solution and the network created between the external water penetration is different, in that under the action of the difference penetration of external water molecules constantly enter the inside. Ion on the network with water electrolysis, positive ions are detached, while the anion groups are still fixed on the network chain, adjacent anion repulsion generated, causing the expansion of polymer network structure, in the molecular structure of the mesh network , entering into a large number of water . Polymer aggregating state, both linear and shape two kinds of structures, due to mild between the grid and the grid cross-linking, the linear part of the freely scalable, while the shape structure so that it remains a certain degree of strength, flexibility can not be limited. Therefore, aquasorb can only be expanded rather than dissolved in the water , as long as the grid elements are not destroyed, its water absorption capacity can still be restored
