High absorbent resin 
 High absorbent resin (Super Absorbent Polymer, SAP) is a new functional polymer materials. It can absorb more than their own weight of hundreds or thousands of times the non-ionized water. Serve gel after absorbing water, even if the pressure it is difficult to squeeze the water. 
 Specific features are as follows: 
 A high water absorption can absorb its own weight several hundred times or a thousand times no ionized water. 
 The high water absorption rate per gram of superabsorbent within 30 seconds, absorbing enough of the hundreds of grams of de-ionized water. 
 High security water-based absorbent gel under external pressure, the water is not easily squeezed out from. 
 High expansive absorbent high absorbent resin gel volume is then expanded hundreds of times. 
 Absorption of ammonia low cross-linking polyacrylate super absorbent resin molecular structure contains a carboxyl anion. 
 The case of ammonia can be absorbed, the deodorizing effect.
