| 摘要:以纸质文献常用的宣纸、报纸和毛边纸为研究对象，探讨文献纸张在酸性环境、不同温湿度作用下，pH值、抗拉强度及纸张纤维组织性能的变化情况。结果表明，在pH值为6.10的酸性环境下，老化192 h及以上，纸张性能发生明显衰变，并随着温度和相对湿度的增加，纸张pH值从碱性变为酸性，强度性能衰变更加明显，纤维组织变得更加粗糙短小。 |
| Abstract:Taking the xuan paper， newspaper and edging paper commonly used in paper documents as the research object， the changing trends of the degradation performance to pH value， tensile strength and fiber structure were measured by changing the conditions of temperature and humidity in acid environment. The results showed that the properties of paper decayed obviously with pH value of 6.10 and the duration time of 192 h or more. With the increase of temperature and relative humidity， the pH value of the paper changed from alkaline to acidic， the tensile strength was significantly reduced， the fiber was rougher and shorter. |
