10种农用保水剂基本性能的比较研究
Comparative study on fundamental properties of ten kinds of super absorbent polymers
摘要
Abstract
In order to understand the basic property of different kinds of super absorbent polymers (SAP) in market presently so that to provide reference for the practice application, water absorbent capacity, water absorption rate, water retention capacity and times of re-absorbency of 10 kinds of SAPs from domestic and overseas, and water absorbing properties in fertilizer solution of two kinds of them were tested. The results indicated that all kinds of SAPs have high water absorption capacity in distilled water, while the water absorption rate of BY, SI, S2, S3 and JF is faster than that of others . Under 351 heated evaporation condition, the water retention capacity of HJ, BY, WT, FB and S2 is better than that of others. After 6 times of recurrent absorbency-drying, the water absorbent of WT, FB, S2 and JD still reaches 63 .4% , 15.1% , 51.5% and 66.6% of their original water absorption capacity, respectively. Three kinds of fertilizer solution in the experiment all have a significant impact on SAP water absorbing properties, and the influence on poly-acrylic-inorganic mineral polymer is stronger than polyacrylamide-inorganic mineral polymer, and the influence of NKP compound fertilizer is stronger than that of organic fertilizer.关键词
