摘要
以淀粉、Fe^(2+)—H_2O_2氧化还原体系和聚丙烯酸钠混炼,在高温下缩合共聚生产的农用保水剂,具有对自然水吸液率高、抗杂质能力较强、固定资产投资少、生产成本低、技术条件要求不高、对环境污染少等特点,适合于农用保水剂的应用时节性生产。
Water-conserving resin made by which starch, Fe^(++)-H_2O_2 redox system and sodium polyacrylate were mixed, condensed and copolymerized in high temperature has high absorption rate of water and ability against inpurity. This technique has many merits, such as few fixed capital, low production cost little pollution and so on. It is possible to make the resin for agriculture at any time.
