皮质文物常见病害及形成原因的研究

为探讨温、湿度变化对皮质文物的影响,以内蒙古博物院及呼伦贝尔民族博物馆藏皮质文物为主要调查对象,对内蒙古地区皮质文物常见的病害种类进行调查,参照已颁布执行的馆藏丝织品病害与图示(WW/T 0013-2008)等相关的国家行业标准有关病害现象的规范描述,对内蒙古地区皮质文物出现的病害现象进行归类和说明。同时利用湿热老化试验,对采集的皮质样品进行老化前后撕裂力、抗张强度、负荷伸长率等理化性能数据的研究,对温、湿度变化给不同鞣制工艺皮质样品所造成影响进行分析,并以此来研究皮质文物的劣化原因。研究结果表明,湿度变化是造成皮质文物劣化的主要因素,且对不同鞣制工艺皮质文物理化性能的影响有明显差异。

Research on the degradation of leather artifacts and its causes

In this study the leather collectibles of the Inner Mongolia Museum and the Hulunbuir Nationality Museum were analyzed in order to understand the effect of temperature and humidity on the leather. Degradation phenomena of leather collectibles from the Inner Mongolia area were classified and illustrated as described in Silk Collectibles Disease and Illustration (WW/T 00132008). Information was collected on tear force, tensile strength, load elongation and some other physical and chemical properties of the leather samples, before and after their aging by dampheat aging methods. This work provided a preliminary analysis of the influence of temperature and humidity on tanned leather samples and will be helpful to understand causes of the degradation of leather cultural relics. The experiments show that change of humidity is the main cause for degradation of leather cultural relics, which also has an obvious influence on the physical and chemical properties of various tanned leather cultural relics.
