| Abstract:The preparation of nano-Mg(OH)2 by different processes, and the effect of the process on particle size and its distribution of nano-Mg(OH)2 were studied. The nano-Mg(OH)2 was used in deacidification treatment of the paper based cultural relics. The results showed that with the aid of ultrasonic and high temperature(90℃), the particles of Mg(OH)2 prepared had a narrow size distribution between 17.9 nm and 86.6 nm, the mean size was 44.2 nm. After deacidification treatment with the nano- Mg(OH)2 the pH value of the papers increased from 4.5 to 8.5. The heat aging test indicated that the papers after deacidification showed a good stability of pH value (~7.5) and the tensile strength (~715 N/m) so that they could be conserved for long-time. |
