Bookkeeper deacidification treatment

Bookkeeper deacidification is a material preservation technology that neutralizes the acidity of acid paper and is located in Pittsburgh, USA.

Developed by Preservation Technologies L.P. (PTLP).

Bookkeepers can safely neutralize books, manuscripts, maps, sheet music, pamphlets, newspapers, etc. and provide long-term preservation of physical materials. First of all, the basic system is to take the materials from the owner, deacidify them at the Saitama factory, and then return them.

It is said that the production of acid-free paper gradually became active in Japan from the latter half of the 20s of the Meiji era, and then the spread of acid-free paper in the 1980s. Deacidification treatment is a material preservation technology that neutralizes the acidity of acid paper and suppresses the acid deterioration of the fibers (cellulose) that make up the paper.

Bookkeeper deacidification is not a recovery technique that whitens or strengthens paper, but is positioned as a precautionary measure to slow down future deterioration. In other words, by deacidifying the paper before it deteriorates, the maximum effect can be expected in the long-term use of paper materials.
