中文摘要: |
研究了不同分散相结构的高分子吸水材料对土壤水分的富集效果影响,结果表明:水溶性聚丙烯酸钾-聚丙烯酰胺聚合物在无机养分溶液中的吸液性较好;小剂量水溶性聚丙烯酸钾-聚丙烯酰胺聚合物富集土壤水分的效果明显优于聚丙烯酸钾-聚丙烯酰胺吸水树脂;并且随水溶性聚丙烯酸钾-聚丙烯酰胺聚合物用量的增加,去离子水的粘度增幅较大,而无机养分溶液的粘度增幅较小。 |
英文摘要: |
The effects of water-absorbed materials with different dispersed phase structure on the form of soil water enrichment were studied. The results showed that the water-absorbing ratio of potassium-polyacrylate-polypropylene-acylamine is better in the inorganic solutions than polypropylene acylamine water-absorbing resin, and it is favorable to retain water. With increasing dosage of water-solubility potassium-polyacrylate-polypropylene-acylamine polymer, the viscosity in dision water obviously increase, while the viscosity in the inorganic solutions increase little. |
