摘要
对以马来酸酐和碳酸铵为原料合成聚天冬氨酸进行红外光谱和凝胶色谱法表征.采用静态阻垢法对聚天冬氨酸进行了阻碳酸钙、硫酸钙结垢能力的测试.结果表明,聚天冬氨酸具有良好的阻钙垢能力,是一种优良的水质阻垢剂.
Polyaspartic acid （PASP） is synthesized from maleic anhydride and ammonium carbonate,The product is characterized by means of IR and gelatin ehromatography. The green scale inhibition properties of PASP are studied. Results show that PASP has a good inhibition effect on CaCO3 and CaSO4,which means that polyaspartic acid can be regarded as a perfect scale inhibitor to be used in cooling water systems.
