书画装裱用浆糊中明矾最佳添加量的探讨

Discussion on Optimum Amount of Alum Added in Paste Concocted for Mounting of Chinese Painting and Calligraphy

明矾是书画装裱用浆糊的主要添加剂之一,起到抗菌防虫作用,但过量使用会对浆糊及装裱书画造成消极影响。为了解明矾对浆糊及装裱书画的影响,明确书画装裱用浆糊中明矾的最佳添加量,本文运用多种分析方法对比不同明矾添加量对浆糊及装裱书画性能的影响。结果表明,当明矾添加量高于5%时,明矾添加量越大,浆糊及装裱书画的性能降幅越大。建议书画装裱用浆糊中明矾最佳添加量不高于5%。

Alum,one of the major additives in the paste concocted for the mounting of Chinese painting and calligraphy,is antibacterial and prevents borers.However,excessive use of alum will have negative impacts on the paste and the mounted Chinese painting and calligraphy.To find out the influence of alum on the paste and the mounted Chinese painting and calligraphy as well as to determine the optimum amount of alum to be added in the paste concocted for the mounting of Chinese painting and calligraphy,this article adopts multiple analytical methods to compare the effects that different amounts of alum have on the paste and properties of the mounted Chinese painting and calligraphy.The results show that,when the dosage of alum exceeds 5%,the more alum is added,the poorer the performance of the paste becomes and the more degradation the mounted Chinese painting and calligraphy experience.It is recommended that the optimum amount of alum added in the paste for the mounting of Chinese painting and calligraphy should not exceed 5%.
