Book treatment method

Abstract

The invention aims to provide a simple and practical book treatment method. Book paper is treated preventively, and compound treatment liquid which is made of a core-shell-structured nano material of a core-shell structure and is capable of slowly releasing alkaline substances is adopted for treating books. A reasonable treatment path is selected according to the acidification degree of to-be-treated paper; not only can the old books with relatively high acidity be treated, but also relatively new books can be protected preventively. According to the method, the books not only can be hardly damaged, and also can be stored for a long time; the pH value and the alkaline retaining amount of the whole treated books keep the relatively good uniformity, and the alkaline retaining amount at different parts of a single page does not exceed 10%. The service life of common paper treated by the method can be prolonged by 5-10 times.
