Archives are various forms of original records with preservation value directly formed by people in various social activities. They inherit the originality of documents and have historical reproducibility. Archives have become one of the most important references in the history of modern social development, and are the inheritance and witness of China's 5000 year history of civilization.

Most archives exist in paper form. In addition to man-made destruction, the biggest risk of paper documents is that they are prone to moisture. Therefore, archives management needs to do a good job to prevent moisture.

The appropriate temperature and humid climate will create the best breeding opportunity for the mold in the archives.

It is a natural phenomenon that archives become damp and moldy. While molds grow, they destroy materials made of archives, books, cultural relics, etc., and produce various metabolic substances such as colored substances, organic acids, etc., which are attached to the surface of various carriers, which will cause varying degrees of harm to the health of archives managers, and are the great enemy of archives preservation.

The common method to remove mold is to use anti mold tablets and anti mold agents, but it can not fundamentally solve the problem of mold in archives. Keeping a relatively dry environment, especially the wall dry, can minimize the breeding of mold.

Archives, a relatively closed building, has very high requirements for fire prevention and noise. The high-power ordinary air dehumidifier not only has certain requirements for the working environment. Moreover, it is noisy, bulky, occupies indoor space, and can not be continuously dehumidified.

Tongqiang technology electroosmosis pulse impermeability dehumidification system, using the principle of electroosmosis, solves the problem of wall humidity from the root, and is suitable for any space that needs dehumidification. By changing the movement direction of water molecules, the corrosion of the wall can be prevented.
