Ways to protect books

1, dustproof

Dust falls on the book, and if it is not cleaned for a long time, the pages will be warped, which will lead to the adhesion of the pages and accelerate the acidification and aging of the paper. Therefore, books must be cleaned regularly.

Step 2 protect yourself from the sun

Ultraviolet rays in sunlight and artificial lighting will accelerate the decline of paper durability and accelerate the yellowing and brittleness of paper. It is suggested to reduce the light intensity of books, reduce the exposure time and control the ultraviolet rays in artificial lighting.

3, mildew prevention

The source of moldy books is mold spores, which are suitable for growing in the environment of 25 ~ 35℃ and humidity above 70%. The library can use a constant temperature and humidity machine to control the temperature and humidity. Individuals can use a hygrometer for monitoring, place dehumidifying bags around the bookcase, and be careful not to place humidifiers, fish tanks and other items with water around the bookcase.
