摘要
本文对新型水处理剂聚天冬氨酸的合成与阻垢性能进行了研究.研究结果表明:聚天冬氨酸的合成工艺简单,对环境和人体无害,热稳定性好,投加量少,阻垢与缓蚀性能良好,是一种可应用于高钙离子浓度水系统的水处理剂.
The synthesis and scale inhibition behavior of polyaspartic acid (PASP) are discussed in this paper. Several conclusions have been drawn. T,he process of synthesizing PASP is simple. The raw material and synthetic process of PASP all could do no harm to environment and body. The PASP can be applied widely in high temperature water system due to its excellent themal stability. The ideal scale and corrosion inhibition behavior can be achieved with PASP even at its low dosages. PASP is perfect to be applied in high Ca2+ concentration water treatment system.
