Paper document deacidifying and reinforcing device

Abstract

The invention relates to a paper document deacidifying and reinforcing device, belonging to the technical field of document restoration. The paper document deacidifying and reinforcing device providedby the invention avoids direct use of a deacidifying liquid for paper soaking in liquid-phase deacidification, so no phenomenon of color fading and wrinkling is generated; meanwhile, a self-prepareddeacidifying agent used in the paper document deacidifying and reinforcing device provided by the invention mainly uses biomass raw materials, has mild reaction conditions, does not generate harm to the environment and is safe and pollution-free; the self-prepared deacidifying agent provided by the invention is rich in alkaloid and alkaline metal salt and can generate a neutralization reaction with acid substances generated by paper document fiber acidification, so the purpose of deacidification is achieved; in addition, a polyphenol component is used as a substrate, and after the self-prepared deacidifying agent fully contacts with the surface of paper, introduction of a gamma ray can promote a substrate monomer and mixtures attached on the surface of the paper to generate chemical reactions like polymerization and cross-linking, so the mixtures on the surface of the paper are sheeted; thus, the paper document deacidifying and reinforcing device achieves the purpose of increasing mechanical properties of the paper, exerts the effect of reinforcement, and has broad application prospect.

Description

technical field [0001] The invention relates to a device for deacidifying and strengthening paper documents, belonging to the technical field of document restoration. Background technique [0002] It has been found through research that the acidic components in paper will cause the aging of paper documents and shorten their storage life. Therefore, paper deacidification technology is one of the important measures for the restoration of paper documents. There are mainly two methods for deacidification of paper documents: liquid phase deacidification and gas phase deacidification. Liquid-phase deacidification is a method of deacidification with alkaline aqueous solution or alkaline organic solution, and gas-phase deacidification is a method of deacidification with alkaline steam. The liquid-phase deacidification method is a paper deacidification method that has been widely used earlier. However, the paper after deacidification by soaking in a deacidification agent will appear...

Problems solved by technology

[0004] The technical problem mainly solved by the present invention: in view of the current liquid-phase deacidification method, the paper after being soaked and deacidified by the deacidification agent will appear fading, wrinkling, etc., and the drying time of the paper after deacidification is long, and the gas-phase deacidification method requires Vacuum deacidification equipment, due to the high cost of equipment and the flammability and explosion of the reagents used, has safety problems, and although the existing deacidification devices have a certain deacidification effect, the reinforcement effect on paper is poor, and the paper machinery The improvement of the strength is not obvious, and a deacidification and strengthening device for paper documents is provided
