Experimental research on the integrated treatment of de-acidification and reinforcement of paper cultural relics by electrosorption

The de-acidification method has always been a hotspot in the research of paper-based cultural relics conservation science. The existing de-acidification methods are either not thorough enough or not easy to operate, requiring innovation and breakthrough. Moreover, the strength of the paper cannot be significantly improved by the simple de-acidification treatment. To achieve the reinforcement of paper, another intervention process is often required, and each intervention may cause damage to the fragile paper cultural relics. This study introduces electrosorption deionization technology to the conservation treatment of paper cultural relics. Based on the electrosorption technology, an integrated treatment of paper de-acidification and reinforcement was applied to sample papers using a composite electrolyte of de-acidification and reinforcement materials and a self-made electrosorption device. The experimental results show that both the de-acidification and reinforcement effects on the paper samples obtained a significant promotion.
