Since the beginning of the year 2011 we have been operating the BoCo1 in Brauweiler and using it are able to deacidify 140 Kg of books in a single work step.
The book conservation process
- Deacidification with decafluoropentane, magnesium oxide and magnesium carbonate (no alkoxide)
- Activation of ingriedients with carbon dioxide
- Consolidation with ethyl cellulose and ethanol
- pH value increases from 5.4 to between 9.0 and 9.3
- Alkaline reserve of 1.4% CaCo3/kg
- Up to 20% consolidation
The BoCo1 book deacidification unit
GSK developed and implemented a process for mechanical conservation of bound materials which is consistent with the latest technology in cooperation with research and development partners: the so-called "Book CP process”. The process is unique worldwide and has special characteristics which are unparalleled in the area of book conservation: It is the world’s first procedure that enables book conservation without alcohol or alkoxide additives. In addition to deacidification, simultaneous consolidation of most materials is possible. The conservation solution – whether with our without stabilisation – already has a strong cleaning effect in itself. In addition, for the first time the unit developed by GSK offers an additional cleaning programme for books which are extremely dirty.
