| titleOfInvention | Method for deacidifying through utilizing soluble tetraborate in supercritical CO2 state |
| abstract | The invention discloses a method for deacidifying through utilizing a soluble tetraborate in a supercritical CO2 state. The method comprises the following steps: putting paper, especially aged and acidified paper in a supercritical CO2 processing apparatus, and processing with an alcohol-water solution containing the soluble tetraborate. The method enables the pH of the paper to be controlled in an optimum range and the deacidifying agent application amount to be reduced. Compared with other methods, the method disclosed in the invention has the advantages of obvious improvement of the paper strength because of the soluble tetraborate in the supercritical CO2 state, and great increase of various mechanical strengths. |
