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。
The water retention properties of water-holding agent, water retention, swelling degree and number of water absorption of the three different dosage forms of super absorbent polymer (large particles, small particles, powder) were studied. The results showed that all three kinds of super absorbent polymers had strong water absorption Sexual and water retention, water absorption times can reach several hundred times its own quality, began to absorb water faster, later slow, no longer water after saturation, and can maintain the indoor water up to 4d for a long time, three formulations of water retaining agent can Repeatedly used many times. It can provide the theoretical basis for the users of SAP to understand the characteristics of SAP and use SAP correctly.
