20种保水剂吸水特性研究

Study on Water Absorbing Character of 20 Kinds of Super Absorbent Polymer

保水剂用于防治水土流失成为水土保持学科中一个新的研究领域,但目前在这方面还缺少系统的研究,为避免盲目应用保水剂,选取国内外教20种保水剂,通过试验测定了它们的吸水特性,从而为进行水土流失防治选取更适宜的产品做出了依据。实验结果表明:ABD型保水剂吸水速率从小到大的顺序为:ABD4型<ABD6型<ABD5型<ABD3型<ABD2型<ABD1型,三种四达类型的试剂中,2型和1型的吸无离子倍率要高于3型,吸盐水倍率则三种相差不大。

Water-retaining agent be used to prevent and control the soil loss becomes a new research domain of the water and soil conservation branch, but still lack systematic research at this aspect at present. In order to avoid applying it blindly, the paper select 20 kinds of water-retaining agent of home and abroad, measure their absorb character through experiment, then choose the more suitable product for preventing and controlling the soil loss.The experiment result shows: the absorb water speed sequence of ABD type Super Absorbent Polymer is ABD4<ABD6<ABD5<ABD3<ABD2<ABD1,in three kind of SI-DA type,the absorb pure water ability of the second and first type is more than the third type, but the absorb salt water ability is not too different.
