目的 研究用于精装书壳的聚氯乙烯发泡革的综合质量评价方法。方法 利用发泡革的微观结构分析和宏观质量测试相结合的方法， 通过数据量化表征和统计分布计算， 探讨两者间的相关联系。结果 对2种发泡革的物理性能和泡孔结构分别作出对比， 泡孔结构均匀、 分布细密、 穿孔率少的发泡革的物理性能检测结果较好。结论 发泡革的微观构造与宏观性能存在一定的关联性， 微观结构对宏观性能有着一定的影响作用和评价作用， 发泡革的泡孔结构越完整， 泡孔大小与分布的均匀程度越好， 感观性能和耐折牢度也越好。

The aim of this study was to investigate a comprehensive quality evaluation method of polyvinyl chloride foam leather for hardcover of books. Using the method of combining the micro structural analysis and macro quality test, the correlation between the two was discussed by means of quantitative characterization and statistical distribution calculation of data. The physical properties of two kinds of foam leather and foam structure were compared respectively. The foam leather with uniform pore structure, fine distribution and low perforation had better test results of physical performance. There was a certain relativity between the micro structure and macro properties of foam leather, and the microstructure had a certain influence on the macro performance. The more complete the pore structure of the foam leather, the higher the uniformity of the pore size and distribution, and the better the performance and the resistance to folding.
