摘　　要：对现行聚羧酸减水剂相关国家标准和铁路标准中的检测方法进行总结,指出其中存在的不足之处,会造成聚羧酸减水剂某些特殊性能指标的缺失。在现有方法基础上,提出补充GPC凝胶色谱法作为检测聚羧酸减水剂母液和复配产品的必要手段,并通过实例说明该方法的优势,对进一步完善聚羧酸减水剂产品的检测工作具有重要的意义。It summarizes the current national standards for polycarboxylate superplasticizers and the detection methods in railway standards,and points out the shortcomings of them,resulting in the lack of certain special performance indicators of polycarboxylate superplasticizers.Based on the existing methods,gel permeation chromatography is added as a necessary means to detect the stock solution and compounded products of polycarboxylate superplasticizers.The advantages of this method are illustrated by an example,which is of great significance for further improving the detection of polycarboxylate superplasticizer products.
