胶研水对几种传统纸张性能的影响

由明矾和胶料配制而成的胶矾水，是书画绘制、装裱和修复过程中经常使用的材料。胶矾水具有防腐、固色和增加机械力度等功能，但对纸质文物的耐久性有一定的影响。本研究选用宣纸、桑皮纸和连史纸等代表性的传统手工制纸，在它们的表面分别涂敷不同浓度的胶矾水，经干热老化后，对比分析它们的酸碱度、白度、耐折度和抗张强度的变化，揭示胶矾水对这几种手工纸张性能的影响，进而探讨其影响机理。研究结果表明，胶矾水将增加纸张的酸度、降低纸张的白度，明胶水能提升纸张的机械强度，而不同浓度明矾对纸张机械强度的影响存在差异。

The Influence of Alum Gelatin Solution on the Performance of TraditionalPapers

Alum gelatin solution, made up with alum and gelation,is an important material forChinese calligraphy and painting. It has advantages such as antibiosis, fastening pigment and increasing mechanical strength of paper. However, the endurance of paper is negatively affected by the material as well.This study examinesseveral types of traditional papers, includingXuan paper, Sangpi paper,and Lianshi pa- per. To be specific, being coated with different concentrations of alum gelatin solution, the papers＇ PH,whiteness,folding strength and tensile strength are measured after being dried and heated, in order toinvestigate the influence of alum gelatin solution on the endurance of tradition- al papers of different types, and to analyze the influential mechanisms. The findings indicate that alum gelatin solution acidulatesthe paper, redncesits whiteness, and increasesthe mechanical strength of the paper.
