Water absorption principle

Water absorption of Superabsorbent polymers the same principle in General QUANSEN retainsupport® superabsorbents , Is Polymer Electrolyte  molecular chain amide group in the water and / Carboxyl group Like charges repel  to molecular chain expansion and due to Crosslinking Limit the expansion  of molecular chain of interactions. A case study of polyacrylamide, Super  absorbent polymer has a lot of amide and carboxy hydrophilic, resin composition of  internal ions and radicals associated with aqueous concentration of the osmotic  pressure difference and polymer Electrolyte  affinity and can be a lot of water uptake and water until the concentration  difference dipears. Control QUANSEN retainsupport® superabsorbent reached a  satisfactory degree of rubber elasticity. Molecular structure ofCrosslinking degree of higher, stronger rubber elastic and rubber elastic and hydraulic balancing  point is its apparent ability to absorb water.

Due to the molecular structure of cross-linked molecular network by water  drawn out cannot use physical methods to water retention.

Thus, similarly composed of polymers Degree of Crosslinking The lower water absorption ratio is relatively higher, less water  retention, stability and strength, and vice versa.Therefore, international use  for a longer period of Super absorbent natural high Crosslinking degree , does not pursue high water absorbency and rate. A case study of  polyacrylamide and its apparent rate is not high, water absorption rate varies  widely depending on the particle size, strength after high water absorbent, a  certain shape, easy to collapse, to soil, water reversibility good  absorption. Super absorbent polymer mixed with ground 5 to 15 centimeters, so  there is more emphasis on the international water absorbency at elevated  pressure. According to particle size, polyacrylamide-water absorption ratio 150-300.


QUANSEN retainsupport® superabsorbent application in Cooling Paste

Can absorb hundreds of times to thousands of its own weight of water,  nontoxic, harmless and pollution-free; exceptionally strong water absorbing  capacity, water retention ability of high moisture absorption cannot be  squeezed out by simple physical methods, and can be repeatedly releasing water,  water absorption. Is a dissolved in water, oil, after the cross-linking  reaction produces a strong adhesive effect and form a Hydrogel polymer, so is  ideal for topical patches of matrix material. In Japan, Showa electrical  production of part in the and polypropylene acid sodium was widely application  Yu Bubba agent ( by skin to drug posted, and beauty  health posted, and quit posted, and weight loss posted, and contraceptive  posted and so on), and mask, and cosmetics in the,  compared General Ming rubber, and seaweed acid sodium, and completely  neutralization of polypropylene acid sodium, traditional matrix raw materials,  Showa electrical of NP Products in the effect of  adhesion, stability, repeated opening has a very distinct advantage.
