胶矾水在颜料老化色差修复中的应用作用分析

Analysis of the Application Effect of Alum Water in Repairingthe Color Difference of Pigment Aging

在古籍修复,书画创作中胶矾水作为常用的材料,其主要是起到防水固色,防墨洇散的作用,同时它还可以起到加固防腐功效。这与胶矾水的作用机理息息相关,胶矾水中的明胶可以包覆纤维起到填充纤维孔隙的作用,防止炭黑粒子的进入,明矾中的离子能够起到絮沉和架桥的作用,协助明胶的作用,助留墨迹。胶矾水的使用还可以在纸张纤维表面生成薄膜,对颜料起到加固的作用,延缓颜料的老化。当然它也存在一些问题,胶矾水中明矾的水解作用会造成纸张的酸化,脆化,所以配制胶矾水是其各成分的添加比例尤为重要。

In the restoration of ancient books,in the creation of calligraphy and painting,alum water is commonly used as a material,which mainly plays the role of water-proof,color fixation,ink blotting prevention,and it can al⁃so play the role of reinforcement and corrosion prevention.This is closely related to the action mechanism of al⁃um water.The gelatin in alum water can cover the fiber to fill the fiber pores,prevent the carbon black particles from entering.The ions in alum can play the role of flocculent and bridging,assist the role of gelatin,and help to retain ink.The use of alum water can also form film on the surface of paper fiber,which can strengthen the pig⁃ment and delay the aging of pigment.Of course,it also has some problems.The hydrolysis of alum in alum water will cause the acidification and embrittlement of paper,so it is particularly important to prepare alum water as the proportion of each component.
