Deacidification system for paper record files and using method thereof

Abstract

The invention relates to a deacidification system for paper record files and a using method thereof. The method comprises the following steps of: connecting dozens of bound paper record files in series through a special clamping bracket, soaking the bound paper record files in a soaking tank in a whole, performing ultrasonic deacidification treatment, condensing a waste gas escaping from the top of the soaking tank, storing the waste gas in a recovery tank, pumping deacidified deacidification liquid to a filter to filter impurities, and then returning the deacidification liquid to a liquid storage tank for reuse. The deacidification system can process dozens or hundreds of files in batch at one time, shows good deacidification effect and greatly saves manpower and material resources.

Description

technical field [0001] The invention relates to the technical field of file preservation and management, in particular to a system for deacidifying paper-based file files and a method for using the same. Background technique [0002] At present, the deacidification agents used for paper archives are mainly divided into three categories: aqueous solution, anhydrous solution, and gaseous deacidification agents. These deacidification agents all have some problems and deficiencies. Aqueous deacidifiers are easy to deform paper and have low efficiency. Chinese patent 201110212874X discloses a method of using soluble tetraborate to deacidify paper. In this method, different concentrations of tetraborate aqueous solutions are mixed with different types of organic solvents, and the methods are soaked, sprayed, atomized or supercritical. Deacidification of paper, especially acidified and aged paper, is carried out in various ways such as treatment. Due to the participation of water...

AI Technical Summary

Problems solved by technology

Due to the participation of water in the deacidification process, the paper is easily deformed, and the paper is easily damaged or destroyed in the state of water soaking

In addition, this deacidification agent and the corresponding method can only be processed one by one and then bound, resulting in a large demand for manpower, complicated procedures, and high costs

[0003] Anhydrous deacidification agents have problems such as low safety, poor deacidification effect, difficult recycling, and environmental pollution. For example, Chinese patent 201510416162 discloses a paper deacidification agent and a corresponding deacidification system and method. The paper is deacidified by shaking and stirring. However, it is difficult to ensure that the file and the deacidification agent are fully contacted by the shaking and stirring method for neutralization reaction, resulting in incomplete deacidification.

In addition, the file will inevitably be damaged during the stirring process, and this method also has problems such as long batch processing time and low efficiency.

[0004] The gaseous deacidification agent and its deacidification method have problems such as high equipment cost, inflammability and explosion, and less alkali residue. The acid method, the device includes an air pump, atomizer, deacidification reactor, liquid collector, and distributor. Analysis shows that its safety production risk is high, the deacidification effect is poor, and the investment in equipment is large
