对聚酯长纤和短纤胎基的比较和研究

Comparison between properties of long and short fiber polyester base materials

比较了长纤聚酯胎和短纤聚酯胎的性能和基于这两类胎体的改性沥青卷材的性能,分析了长纤和短纤聚酯胎对改性沥青卷材性能的不同影响。在分析比较大量实验数据的基础上指出,长纤比短纤具有更好的综合物理性能,且质量稳定;长纤聚酯胎改性沥青卷材比短纤聚酯胎改性沥青卷材性能更好、更稳定。

The article makes a comparison between properties of long and short fiber polyester base materials and analyzes the effects of the two materials on properties of modified bitumen membrane.Having analyzing a great deal of experimental data,the article also points out that long fiber has better comprehensive physical properties and more stable in quality than short one.In addition,the properties of modified bitumen membrane with long fiber polyester base material are better and more stable than with short fiber one.
