Description
Technical field
The present invention relates to a kind of deacidification system, particularly relate to a kind of application plasma discharging teclmiques and carry out taking off acid-treated system continuously.
Background technology
China is an ancient civilized country with long history and brilliance culture, and the papermaking technology of invention and the art of printing have recorded the development of human civilization.The paper relics such as books in modern times, calligraphy and painting, newspaper, archives of in store ten hundreds of preciousness in various library of China, museum, archival agency, they are Chinese nation's excellent traditional culture elite places, having not reproducible important historical cultural environment, is the pillar of the spiritual civilization of the Chinese nation.
But with the passing of the years, the acidifying situation of paper document is day by day serious, and the phenomenons such as jaundice is gone mouldy, efflorescence is cracked have appearred in a large amount of ancient rare book, protect these cultural data to be faced with stern challenge.A large amount of modern times, paper relics caused paper variable color, mechanical strength significantly to decline even one touching and namely break due to paper acidifying.
Paper relics from quality be broadly divided into traditional-handwork paper and modern times machine finished paper.It has been generally acknowledged that, the main chemical compositions of paper is cellulose, is formed by the glucose key combination in cellulose macromolecule between basic ring.The aluminum sulfate that machine-made paper is retained in a manufacturing process is acid after meeting hydrolysis, when it acts on paper fibre element, glucose key in cellulose macromolecule between basic ring is ruptured, the degree of polymerization is caused to reduce, thus cause paper acidifying, embrittlement and going bad, show as the structural deterioration (i.e. the decline of mechanical strength) on variable color macroscopically and microcosmic and " self-destruction ".And the obvious acidification phenomenon that have also discovered equally in the traditional-handwork paper relics that it has been generally acknowledged that not easily acidifying in various degree.
Great many of experiments shows, modern times, machine-made paper generally only had the life-span of 50 ~ 60 years, and after depickling, its theory " life-span " can reach about 500 years.But under the long lasting effect of the extraneous acidifying factors such as paper self lignin oxidation, hydrolysis and air etc., still likely there is " returning sour regurgitation " phenomenon in the paper of depickling after long-term placement.
Meanwhile, due to reasons such as dyeing, crease-resistant process, washing resistance process, fabric also uses a large amount of acid in the process of producing.Therefore, there is obvious acidification phenomenon equally in fabric.
Although people have carried out the research of a large amount of paper deacidification in modern times aspect, do not obtain desirable deacidification technique yet so far.Conventional solution depickling method needs pending sample to be immersed in deacidification agent, causes the various defect self being difficult to overcome, as paper distortion, fades, the toxicity of chemical reagent, efficiency is low, cannot realize multi-level process, is difficult to control deacidification agent consumption and prevent sour regurgitation etc.; Although and the depickling of traditional meteorological depickling method is fast and have the resultant effect of desinsection, sterilization, the acquisition of its high vacuum condition causes it very harsh to the requirement of equipment, and hidden danger is many, and investment is large and be difficult to the shortcoming preventing sour regurgitation.Therefore, study novel, efficient, can the depickling theory and technology of the extensive handling of paper of industrialization be instant thing.
Particle energy contained in atmospheric non-equilibrium plasma is high, active strong, effectively the alkaline deacidification agent in steam can be brought into fibrous inside and make paper fully and completely depickling from inside to surface, thus prevent acidic materials that thoroughly depickling causes staying fibrous inside still can the degraded of accelerating fibers, the method both can break away from the restriction that conventional physical method is subject to vacuum condition, also can overcome the negative effect that solvent-borne type chemical reagent processing method is brought.And the temperature of plasma can be low to moderate normal temperature, can not cause damage to paper, both can break away from the restriction that conventional physical method is subject to vacuum condition, also can overcome the negative effect that molten other type chemical reagent processing method is brought.Therefore plasma can be used will to have high-octane active hydroxide ion and to introduce paper surface and inside, with the acidic materials generation neutralization reaction in paper, realize the contactless plasma depickling to paper document, the adhesion that simultaneously also can increase to a certain extent between fiber improves the macro strength of paper.
Publication number is the Chinese patent literature of CN102242530A, discloses a kind of acid stripping method of paper relics.Its equipment requirement is high and can not realize continuous depickling, and production efficiency is low, be unsuitable for large-scale production.
