沥青乳液固含量测定试验方法比较与探讨

Comparison and Discussion on Test Methods for Measure Asphalt Emulsion Solid Content

固含量作为沥青乳液最基础的质量指标,测量准确对生产和销售具有重要的意义。对比分析了适用于沥青乳液固含量测定的6种试验方法,并指出了不足。参照《建筑涂料用乳液》(GB/T 20623—2006)中不挥发物质量分数测定方法,对平底圆盘中是否加有滤纸进行了对比试验,提出了改进意见。

As the most basic quality index of asphalt emulsion,the solid content is of great significance for production and sales.Comparative analysis of six test methods applicable to the measure of asphalt emul-sion solid content and pointed out the shortcomings.Refer to method for measure the mass fraction of non-volatiles in‘emulsion for architectural coatings’(GB/T 20623-2006),a comparison test is carried out whether filter paper is added to the flat bottom disc,and suggestions for improvement are put forward.
