| 摘 要： | 介绍了一类新型的土壤结构改良用聚合物———磺化氨基树脂(SAF)。通过扫描电镜(SEM)观察证实了树脂对沙土颗粒的连结作用,从而使其形成较大的团聚体结构。为得到良好的风沙土结构改良效果,SAF树脂的磺化度应该为14.0%~18.0%,氨基原料中三聚氰胺的用量应该占尿素质量的20%。由此制备的SAF树脂当其施用剂量为风沙土干质量的0.3%时,对风沙土的结构改良效果与阴离子型聚丙烯酰胺(PAM)在施用剂量为0.1%时的效果相当。经估算,此时SAF树脂的材料成本仅占PAM的75%。

| Abstract: | A new series of polymer material, namely sulfonated amino-formaldehyde resin (SAF) was introduced for soil amendment in this paper. Through SEM observation, it was testified that sand grains were bonded together by the resin to form large aggregates. According to results obtained, degree of sulfonation (DS) of the resin should be 14.0 % - 18.0 %, and the dosage of melamine as amino constituent should be 20 % by weight of urea, so as to achieve the best performance on improving structure of aeolian sandy soil. If SAF resin prepared in such a way was applied on sandy soil at the rate of 0.3 % (by dry weight of soil), its performance on improving soil structure was similar to that of anionic polyacrylamide (PAM) at the rate of 0.1 %, but the material cost of SAF resin only accounted for 75 % of that of PAM through cost estimation. |
