Abstract

The invention provides a deacidification system. The deacidification system comprises a deacidification solvent atomization device, a radio-frequency discharge device and a drive device, wherein the deacidification solvent atomization device comprises a deacidification solvent tank, an atomization generation mechanism and a spray head for spraying a deacidification solvent towards a sample to be deacidified, the deacidification solvent tank, the atomization generation mechanism and the spray head are communicated in sequence. The radio-frequency discharge device comprises a discharge electrode, a grounding electrode and a matched circuit, a discharge zone for processing the sample to be deacidified is arranged between the discharge electrode and the grounding electrode, and the drive device is used for driving the discharge electrode or the sample to be deacidified so as to change relative positions of the discharge electrode and the sample to be deacidified. The deacidification system processes the sample at normal temperature and normal pressure, is safe in use and is free of pollution to an outside environment. The deacidification system is simple in structure, convenient to use, short in processing time and thorough in deacidification, does not easily cause re-acidification and effectively avoids sample deformation and discoloration.

Description

technical field [0001] The invention relates to a deacidification system, in particular to a system for deacidification treatment using plasma discharge technology. Background technique [0002] my country is an ancient civilization with a long history and splendid culture. The invention of papermaking and printing records the development of human civilization. There are tens of thousands of precious modern books, calligraphy and paintings, newspapers, archives and other paper cultural relics preserved in various libraries, museums and archives institutions in our country. Historical and cultural value is the pillar of the spiritual civilization of the Chinese nation. [0003] However, with the passage of time, the acidification of paper documents has become more and more serious, and a large number of ancient rare books have become yellow, moldy, pulverized and fragmented. The protection of these cultural materials is facing severe challenges. A large number of modern pap...
