偏振光显微镜在木斯塘档案纸张纤维检测中的运用

随着无损和微损检测技术的发展,对档案所用纸张的微观分析得到了越来越多的运用。目前最常用于纸张纤维观察与检测的方法是光学显微镜染色观察法,但该方法存在对染色剂的质量有很大依赖性的局限,利用偏振光显微镜则可以在不使用染色剂的情况下,更好地从纤维形态特征的角度作出纤维种类的鉴别。通过对偏振光显微镜运用于纸张检测分析中的相关研究进行综述,发现目前该技术在纸张纤维观察方面的研究尚处于理论分析阶段,缺乏实际的应用研究。利用偏振光显微镜对一批木斯塘档案所用纸张的纤维形态和其他成分进行观察与分析,说明偏光显微法在对档案纸张纤维形态的观察与判断以及对造纸纤维与纸浆中的其他细胞、晶体等物质进行区分时的有效应用及其独特的优势。

Application of polarized light microscopy in the fiber detection of paper used in Mustang archives

With the development of non-destructive and micro-destructive testing technologies, micro-analysis of paper used in archives has been increasingly applied. At present, the most commonly-used method for paper fiber observation and detection is the staining method in conjunction with optical microscopy; however, this method depends greatly on the quality of staining agents. Polarized light microscopy can be used without staining fibers and thus provides a better way for fiber identification from the perspective of fiber morphological characteristics. By reviewing the related research on the application of polarized light microscopy in the detection and analysis of paper, it is found that the current research on the fiber detection of paper by this technology is still in the stage of theoretical analysis and lacks practical applications. Observation and analysis of the fiber morphology and other components of paper used in Mustang archives using polarized light microscopy illustrate the effective application and the unique advantages of this method for the observation and identification of paper fibers used in archives and for the distinguishment between fibers and other cells or crystals in papermaking pulp.
