改性淀粉阻垢性能的研究

Investigation on the Modified Starch of Scale Inhibitor

改性淀粉是一种环保型水处理阻垢剂,具有天然、无毒和易生物降解等特点。采用不同方法对淀粉进行了氧化改性,利用模拟循环冷却水方法研究了氧化改性淀粉的阻垢性能,确定了可以不同程度提高淀粉阻垢效率的淀粉氧化改性方法,研究表明次氯酸氧化法改性淀粉具有满意的阻垢效果。

As an eco-friendly scale inhibitors,modified starch is widely used in the treatment of circulating cooling water.The oxidative modification process of starch have been explored,scale inhibition behavior has assessed by simulated methodology of circulating cooling water,the investigation showed that scale inhibition rate of oxidative modified starch have been improved by sodium hypochlorite oxidization.
