| Abstract:A kind of pressure atomization device was designed and used for paper deacidification. Effects of the kind and dosage of deacidification agent and treatment time on paper surface pH value and mechanical properties were investigated. Natural deacidification agents TS4, calcium propionate ethanol aqueous solution and isobutylamine ethanol aqueous solution were chosen as deacidification agents. The results showed that the optimal dosage of each deacidification agent was different: dosage of TS4 was 10 mL, while dosages of calcium propionate ethanol aqueous solution and obutylamine ethanol aqueous solution were 15 mL, and all the optimal treatment times of deacidification were 12 hours. After deacidification, mechanical properties of treated paper including tensile strength, stretch and tear were all enhanced significantly TS4 in particular. It was concluded that pressurized atomization device designed in this experiment was appropriate for paper deacidification using organic solvent deacidification agents at room temperature and ordinary pressure. |
