Description
Technical field
The present invention relates to archives preservations and administrative skill field, and in particular to a kind of archives of paper quality files deacidification system and its
Application method.
Background technique
Currently, the deacidification agent for paper archives files is broadly divided into three classes: aqueous solution class, anhydrous solution class, gaseous state class,
All there are some problem and shortage in these types of deacidification agent.Aqueous solution class deacidification agent is easy to keep paper distortion, effect low.Chinese patent
201110212874X discloses a kind of method for carrying out depickling to paper using soluble tetraborate, and this method will be different dense
The tetraborate aqueous solution of degree is mixed with different types of organic solvent, more using immersion, sprinkling, atomization or first supercritical processing etc.
Kind mode, the paper that aging is especially acidified to paper carry out depickling processing.Due to there is water participation to be easy in deacidification
Lead to paper distortion, and paper is highly susceptible to damage or be destroyed in the state of water-soaked.In addition, this deacidification agent and phase
Then the method answered can only be handled a sheet by a sheet binds, cause manpower demand big, complex procedures, with high costs.
That there are safeties is low for the deacidification agent of anhydrous solution class, deacidification effect is poor, is not easily recycled, pollutes the problems such as environment, example
If Chinese patent 201510416162 discloses a kind of paper sheet deacidification agent and corresponding deacidification system and method, the technology is using leaching
The mode that bubble rocks stirring carries out depickling to paper, however rocks agitating mode and be difficult to ensure that archives files sufficiently connect with deacidification agent
Touching carries out neutralization reaction, and depickling is caused to be not thorough.In addition, inevitably damaging files in whipping process, there is also at batch for this method
Manage the problems such as time is longer, efficiency is lower.
The problems such as that there are costs of equipment is high, inflammable and explosive for gaseous state deacidification agent and its acid stripping method, alkali less residue, such as in
State's patent 2011101087850 discloses a kind of pressurizing atomizing deacidification device and the method using the device pressurizing atomizing depickling,
The device includes air pump, atomizer, depickling reactor, liquid trap, distributor, its Safety Risk in Production known to analysis is very high, is taken off
