发明名称 PROCESS AND DEVICE FOR NONPOLLUTING MASS DEACIDIFICATION OF BOOKS AND OTHER PAPER PRODUCTS
摘要 Process and device for the nonpolluting mass deacidification of books and other printing and paper products with the predrying of these products by high-frequency radiation in a vacuum, then the application of a neutralization treatment with solutions for deacidification and the subsequent drying of solvents used also by high-frequency radiation in a vacuum. Preferably a single treatment chamber (1) for predrying, neutralizing and drying is used. The interior space of the treatment chamber can be exposed to high-frequency/microwave radiation of a generator (2), to which devices (4, 8, 9; 10 to 19 and 5) combined into a closed movable unit with chamber (1) are connected for the supply and removal of the solutions, for the evacuating of air and for the environmentally favorable separation of vapors when drying the accumulated exhaust air. The process and the device make possible a quick and efficient, as well as nonpolluting, mass deacidification with nearly complete recovery of the solvents.
