摘要
通过试验研究,总结了各种物理、化学方法对天然革和人工革鉴定上的准确性和有效性。结果表明:粒面、背面及毛孔观察法、革样撕裂口形态观察法、烟气收集法、溶剂溶解法、湿热法、傅里叶红外光谱法、电镜扫描法以及热重分析法,判定天然革和人工革的有效率为100%,元素分析法则可有效鉴定人工革样属于聚氯乙烯(PVC)人工革还是聚氨酯(PU)人工革,以及PVC-PU复合人工革。
The genuine and synthetic leather were identified by different physical and chemical measurement mathods,and the accuracy and effectiveness of these methods were reviewed. It’s clear that the effective rate of determining genuine and synthetic leather is 100% by using observation methods involving in grain,back,pore and tear morphology,the flue gas collection,solvent dissolving method,wet heating treatment,FI- IR,SEM and TGA. The element analysis is an effective way to identify polyvinyl chloride( PVC) leather,polyurethane( PU) leather and PVC- PU leather.
