酸化是影响纸质档案寿命的关键因素，去酸的主要方式是碱中和，然而去酸后pH值的控制有严格的要求，因此，去酸剂的选择必须要慎重。本文首先采用硼砂和氧化钙混合去酸剂，系统开展了酸性档案纸的去酸研究。并在高压二氧化碳条件下，对混合去酸剂的去酸过程进行了初步的探究。研究结果表明，硼砂和氧化钙混合去酸剂在去酸和增白两个方面均取得良好的效果。

Abstracts： Acidification is a key factor affecting the life of paper archives. Alkali neutralization is the main way for deacidification; however, pH value＇s control has strict requirement after deaeidification. Therefore, the selection of an appropriate deacidite is very important for the deaeidification. In this paper, new methods of combining two kinds of deacidites, borax and calcium oxide, were adopted to study the de- acidification of paper. The deacidification process under the conditions of high pressure carbon dioxide was also inquired. The results demonstrated that the combination of borax and calcium oxide was benefi- cial for both deacidifieation and bleaching.
