Optimization of Technology to Neutralize Acidity of Paper Matter CSC BOOK SAVER
One of the reasons of paper destruction is the increasing acidity, based on hydrolyzing destruction of cellulose because of acid accumulation in paper during its long storage. In different countries of the world, various technologies to neutralize acidity of paper items are used. In the Russian National Library, the technology of mass neutralization of paper's acidity CSC BOOK SAVER is employed. Taking into consideration, the gained, during the research, results, the following changes in technology of neutralization of documents' paper by CSC BOOK SAVER can be recommended to achieve optimized effect: • 4% concentrated neutralizing solution; • The neutralizing process temperature -5 0C; • Time of neutralization process 15 minutes.
