This paper investigated the effects of different factors on the scale inhibition ratio of chitosan.It is indicated that the chitosan has excellent scale inhibition ability over common anionic scale inhibitor owing to its unique characteristics of polycation structure.The significance of this research lies on that it quests for a new polycation scale-inhibition pattern, different wholly from the traditional theory based on the anion scale inhibition mode.%探讨各种因素对壳聚糖阻垢率η的影响, 结果表明壳聚糖因其独特的聚阳离子结构特性而显示出较之普通阴离子型阻垢剂优越的阻垢能力.对传统理论以阴离子吸附阻垢的单一模式做出了补充, 为促进循环冷却水系统阻垢技术发展提出了新的思路.
