Abstract

The invention belongs to the technical field of paper deacidification, and specifically relates to a paper deacidification agent, and a paper deacidification system and a paper deacidification method thereof. The paper deacidification agent comprises nanometer oxide particles, a silane coupling agent and n-perfluorooctane liquid, wherein the nanometer oxide particles are suspended in the n-perfluorooctane liquid after coated by the silane coupling agent, and the nanometer oxide particles can also be replaced by nanometer magnesium hydroxide particles. The paper deacidification system comprises a deacidification liquid storage tank, a centrifugation pump, a deacidification device and a circulation device which are in successive connection, wherein the outlet of the circulation device is respectively connected with the inlet of the deacidification liquid storage tank and the inlet of the deacidification device; a circulation loop is formed between the deacidification device and the circulation device; and the deacidification device is also connected with the deacidification liquid storage tank via a deacidification liquid recovery device. The paper deacidification method comprises the following steps: putting a literature into the deacidification device, then pumping the paper deacidification agent into the deacidification device, shaking the literature, subjecting deacidification liquid to circulation, pumping the deacidification liquid back, and carrying out condensation recovery. According to the invention, safety and effectiveness are obtained; and the paper deacidification agent has the advantages of easy recovery, good effects and low cost.

Description

technical field [0001] The invention belongs to the technical field of paper deacidification, and in particular relates to a paper deacidification agent and a paper deacidification system and method thereof. Background technique [0002] In libraries and archives, there are a vast collection of paper books and archives left over from history. As the carrier of these books and archives historical and cultural heritage, paper needs to be preserved for a long time and maintain a certain performance. The main component of paper is fiber, and the durability of paper is an important issue concerned by the field of books and archives. The factors that determine the durability of paper include the quality of papermaking raw materials, the physical and chemical properties of fiber chemical components, and the papermaking process. In ancient China, handmade paper was often used. The raw materials for handmade paper are mainly long-fiber hemp and bark plants, which contain high cellu...
