1、Based on the particularity of the composition of paper archives (archives), vacuum sealing technology is adopted to keep the paper archives in a vacuum state. It can isolate the archives from moisture, harmful gas and dust in the air, destroy the living environment for mold and insects, and achieve the desired preservation effect.
Compared with traditional archives preservation, archives vacuum bag packaging and preservation can delay the large cost investment of warehouse and equipment, reduce the subsequent resource consumption during preservation, and have the direct effect of dust-proof, waterproof, moisture-proof and harmful gas prevention. At the same time, the vacuum microenvironment will inhibit the growth and reproduction of harmful microorganisms endangering archives, and play the effects of mold prevention, insect prevention and accelerated aging. Keep the paper archives away from problems such as yellowing, discoloration, mildew, humidity, insect bite, water stain and fading of handwriting, so as to achieve the long-term protection effect of archives.
2. The carrier of paper archives is paper, which is made of wool fiber, phloem fiber, wood fiber and gramineous fiber. The main components of these raw materials are cellulose, hemicellulose and lignin. According to the physical and chemical properties of paper archives, in order to prolong the service life of archives, the environment must be protected. Like the environmental requirements of standard archives (rooms), it is necessary to prevent mildew, moisture, dust, insects and light, and build a standard archives warehouse.
