| 摘 要： | 通过对保水剂3种不同剂型(大颗粒、小颗粒、粉末)的吸水性能、保水性、溶胀度和吸水次数等保水特性的研究，结果证明3种不同剂型的保水剂均具有较强的吸水性和保水性，吸水倍数能达到自身质量的几百倍，开始吸水时快，以后较慢，饱和后不再吸水，且在室内均能保持水分达4d之久，3种剂型保水剂均能反复利用多次。可为保水剂使用者了解保水剂的特性和正确使用保水剂提供理论依据。 |
| 关 键 词： | 保水剂 保水特性 吸水性能 溶胀度 |

| Abstract: | An experiment was conducted to study the water-absorbing capacity, water retention, bulge degree and the times of absorption for three forms of absorbent polymers. Results show that these absorbent polymers all have powerful water-absorbing capacity and water retention. The times of absorption can be hundreds of times of its own weight. At beginning, the speeds of absorption are quick, and then slow obviously. They no longer absorb water when the absorptions reach the saturation point, and they can maintain the moisture as long as four days. These absorbent polymers can be used repeatedly. This experimental result will provide the characteristics and the proper use of absorbent polymers for users. |
