Paper document deacidification device and method

Abstract

The invention provides a paper document deacidification device and method. The device comprises a controller, a base, a document bracket, a paper detection device, an atomizing spraying device, a page turning device, a feed liquid pool, a hydrosolvent deacidification liquid defined amount control device and hydrosolvent deacidification liquid delivery pipelines, wherein the document bracket is arranged on the base, the paper detection device and the atomizing spraying device are arranged on the document bracket and located on the two sides of the document bracket respectively, and the page turning device is arranged in the middle of the document bracket; the hydrosolvent deacidification liquid defined amount control device is arranged between the atomizing spraying device and the feed liquid pool, the hydrosolvent deacidification liquid defined amount control device is connected with the atomizing spraying device and the feed liquid pool through the hydrosolvent deacidification liquid delivery pipelines respectively, the paper detection device, the hydrosolvent deacidification liquid defined amount control device, the atomizing spraying device and the automatic page turning device are all electrically connected with the controller, and a paper pH detector is arranged on the paper detection device. In this way, uniform deacidification of the whole paper document is achieved, alkali stock is uniform, and deformation and damage of the document are avoided.

Description

technical field [0001] The invention belongs to the technical field of library document protection, and in particular relates to a paper document deacidification device and deacidification method. Background technique [0002] Due to the influence of the material structure and the storage environment, the phenomenon of paper acidification will occur in the long-term preservation of modern machine-made paper documents. It is a worldwide issue to protect paper documents and reduce acidification damage. [0003] The deacidification treatment of the entire paper literature at home and abroad has two major methods: gas phase deacidification treatment and liquid phase deacidification treatment; liquid phase deacidification mainly includes aqueous solvent deacidification solution and organic solvent deacidification solution. Gas-phase deacidification and organic solvent deacidification have the common problems of being toxic, inflammable and explosive, polluting the environment, an...
