Description
Technical field
Carried out at continuous depickling the present invention relates to a kind of deacidification system, more particularly to a kind of application plasma discharging teclmiques
The system of reason.
Background technology
China is one has the ancient civilized country of long history and magnificent culture, and the papermaking technology and the art of printing of invention have recorded
The development of human civilization.In store ten hundreds of precious modern times in various libraries of China, museum, archival agency
The paper relics such as books, calligraphy and painting, newspaper, archives, they are Chinese nation's excellent traditional culture elite places, with not reproducible
Important historical cultural environment, be the pillar of the spiritual civilization of the Chinese nation.
However as the passage in years, the acidifying situation of paper document is increasingly serious, and a large amount of ancient rare books occur in that jaundice
Go mouldy, the phenomenon such as efflorescence fragmentation, protect these cultural data to be faced with stern challenge.A large amount of modern times paper relics are due to paper
Open acidifying and cause paper discoloration, mechanical strength significantly to decline even one and touch i.e. broken.
Paper relics are broadly divided into traditional-handwork paper and modern times machine finished paper from quality.Generally, it is considered that paper
Main chemical compositions are celluloses, are formed by the glucose key combination between basic ring in cellulose macromolecule.Machine-made paper is in manufacture work
The aluminum sulfate retained in skill is met after hydrolysis in acidity, when it acts on paper fibre element, is made in cellulose macromolecule between basic ring
Glucose key be broken, cause the degree of polymerization to reduce, thus result in paper acidifying, embrittlement and go bad, show as macroscopically
Discoloration and it is microcosmic on structure destruction (i.e. the decline of mechanical strength) and " self-destruction ".And it has been generally acknowledged that being difficult the tradition of acidifying
Different degrees of obvious acidification phenomenon is equally have also discovered in manual paper relics.
Many experiments show that modern times machine-made paper typically only has the life-span of 50~60 years, after depickling its theoretical " life-span "
Can be up to 500 years or so.But in the long lasting effect of the extraneous acidifying factor such as paper itself lignin oxidation, hydrolysis and air etc.
Under, the paper of depickling is after long-term placement it is possible to there is " returning sour regurgitation " phenomenon.
Simultaneously as the reason such as dyeing, crease-resistant treatment, washing fastness treatment, fabric is during production
Also substantial amounts of acid is used.Therefore, obvious acidification phenomenon is equally existed in fabric.
Although people have carried out the research in terms of a large amount of modern times paper deacidifications, do not obtain yet so far preferably de-
Technic acid.Conventional solution depickling method needs to be immersed in pending sample in deacidification agent, causes the various defects for itself being difficult to and overcoming,
Such as paper distortion, fade, the toxicity of chemical reagent, efficiency is low, it is impossible to realize multi-level treatment, it is difficult to control deacidification agent consumption and
Prevent sour regurgitation etc.；Although and the depickling of traditional meteorological depickling method is fast and with desinsection, the resultant effect sterilized, its high vacuum condition
Acquisition cause its requirement to equipment very harsh, hidden danger is more, and investment is big and is difficult to prevent the shortcoming of sour regurgitation.Cause
This, it is very urgent thing to study depickling theory and technology that is new, efficient, can industrializing extensive handling of paper.
Contained particle energy is high, active strong in atmospheric non-equilibrium plasma, can effectively by steam
Alkaline deacidification agent brings fibrous inside into so that paper fully and completely depickling from inside to surface, so as to prevent not thorough depickling from leading
The acidic materials that cause stays in fibrous inside still can be with the degraded of accelerating fibers, and the method can both break away from conventional physical method and be subject to
The limitation of vacuum condition, it is also possible to the negative effect for overcoming solvent-borne type chemical reagent processing method to bring.And, plasma
Temperature can as little as normal temperature, paper will not be caused damage, can both break away from conventional physical method and limited by vacuum condition,
The negative effect that molten other type chemical reagent processing method can also be overcome to bring.Therefore can will be with high energy using plasma
There is neutralization reaction in the acidic materials that the active hydroxide ion of amount is introduced in paper surface and inside, with paper, realize to paper
The contactless plasma depickling of matter document, while the adhesion that can also increase to a certain extent between fiber improves paper
Macro strength.
The Chinese patent literature of Publication No. CN102242530A, discloses a kind of acid stripping method of paper relics.It sets
It is standby to require high and continuous depickling be realized, low production efficiency, it is unsuitable for large-scale production.
