Description
Technical field
The present invention relates to a kind of using super critical fluid technology and carry out the mildewproof sterilized method of ancient books.
Background technology
" ancient books " is the write legal document for others abbreviation of nationality of Ancient Chinese, mainly refers to write or the books that had Chinese classical binding and layout form in 1912 in the past of version seal.Ancient times, books were China's important historical cultural heritages, it is the intellectual product of human civilization, also be the main carrier and the sign of human material progress and culture, being allo with each period of history human culture and development of productivity process, is that the brilliant civilization history in 5,000 years of the Chinese nation has stayed an abundant historical and cultural heritage to us.According to statistics, present literature of ancient book by each library collection of China has reached 3,000 ten thousand.But since of the remote past, misfortunes such as suffering chaos caused by war extreme misery, rat eaten insect bite gone through, and some precious rare book handed down from ancient times also is riddled with gaping wounds, incomplete.Duration today, it is precious further only to subtract the ancient books handed down from ancient times that does not increase, and wherein about 5% literature of ancient book has reached the degree of serious damage.Therefore, how protecting these precious literature of ancient book, damaged literature of ancient book is repaired timely, is the urgent and difficult task of pendulum in face of ours.
Ancient books involved in the present invention not only refers to ancient ancient books, also is fit to new ancient books, has promptly write or published the papery cultural information record carrier in 20 years, as the secondhand book of common theory, old newspaper, old picture etc.Should implement the policy of " putting prevention first integrated control " in the ancient books management work, " putting prevention first " mainly is exactly mildew-resistant and insect protected.The ancient books harmful microorganism is a kind of warehouse harmful microorganism, and common ancient books harmful microorganism is the part of antibacterial, actinomycetes and mycete, and wherein mycete is based on penicillium sp and aspergillosis, and antibacterial mainly contains coccus, bacillus etc.They make material with ancient books is culture medium, secretes the enzyme of ancient books making material of can decomposing or liquefy.On the one hand, the ancient books harmful microorganism carrier material that liquefied makes it to go mouldy, bond, and greatly reduces the durability of ancient books carrier, grievous injury the safety of ancient books.On the other hand, the ancient books harmful microorganism secretes pigment again, forms yellow, green, blue or green, black mottle on the papery ancient books.The severe contamination writing causes the permanent or part of ancient books not readable, affects the true of ancient books information.Just can make the plain damage 10～60% of paper fibre at three months according to relevant report mycete.Therefore, mildew-resistant is instant work in the ancient books management.In addition, a lot of antibacterials usually are to exist with the spore form, and the densification of spore film is heat-resisting, and resistance is strong, therefore often to kill spore as the foundation of estimating sterilization effect.And ancient books is different from some other common object, does not destroy under the prerequisite of ancient books in assurance, and also there is very big difficulty in the effect that reach sterilization fully.Moth has also played the part of a very important role in the destructive process of ancient books, how to kill the problem that moth also is a headache.
After the Cai Lun of Eastern Han Dynasty invention paper, just paper replaces the main carrier that former bamboo inscribed wooden slip, book copied on silk etc. become shorthand, as jute paper, bark paper, bamboo paper etc.Modern chemical analysis shows, GUZHI is to be that raw material is made by hand and formed with pure plant fibers such as bamboo, cotton, fiber crops.Cellulose in its composition and mineral (Pulvis Talci of interpolation, Gypsum Fibrosum etc.) and starchiness (paste) etc. all are the nutriments that stupid worm maintains life.And seldom contain the chemical constituent of insect protected, also of the remote past, so subject to most to damage by worms.
And the mouldy of paper is due to mycete grows under the certain humidity condition, how to prevent mouldy can setting about in all its bearings, the one, and the environment that keeps dry, the 2nd, the growth of adding antifungus agent mould fungus inhibition in material.Obtain throughout the year with yellow tiller juice dip-dye paper ancient times, and the mothproof soaked dip-dye paper of yellow paper, Pericarpium Zanthoxyli or Fructus Capsici obtains green pepper paper.Some library carries out insect protected with Herba Cymbopogonis, Camphora, Lignum cinnamomi camphorae, Wan Nianhong etc. and carries out the mildew-resistant processing now.More then be to adopt modern means to carry out the disinsection mold-proof of ancient books.
Modern used microwave method treating capacity is little, and treatment temperature is wayward, easily causes ancient books to damage; The x ray irradiation x method can be sterilized in deinsectization, but the expense height is used inconvenient; Vacuum-packed method only is fit to the lower rare book of utilization rate; Plasma sterilization is complicated operation then; Chemical fumigation method toxicity is big, is fit to the mildewproof sterilized biological proofing of storehouse.These methods can not play good effect for the disinsection mold-proof sterilization of this special object of ancient books.
