大多数现代墨水遇水涸化、褪色的现象是档案界迫切需要解决的重大问题之一,它不但影响档案的耐久性,而且限制了现代先进保护、修复技术的利用,如纸浆补洞自动化技术就不适用于水溶性墨水书写的档案。因此,在修复之前,必须先对墨水进行加固。Martine Leroy和Francoise Flieder经过大量的调查和研究,在固定墨水方面取得了令人满意的结果。 一、加固剂的选择 选择最适加固剂,必须考虑对纸张无害这一因素。在众多加固剂中,对Sandoi公司的产品(Dermafix S、In-dosol E_(50)、Tergotan GS、Sandofix WE)和 Bayer公司一般用于染料加固的产品(Tanigan LD)作了全面分析(见表4)。通过初步研究,他们筛选出四种加固剂:X321、Indosol E_(50)、Tanigan LD和Sandofix WE,确定了每一种加固剂浓度、浸渍时间和最佳的干燥方法,并检验了用碳酸氢镁去酸对加固的影响。X321、Indosol E_(50)、Tanigan LD
Most modern inks encounter water drying up and fading phenomenon is one of the major problems urgently needed to be solved by archives. It not only affects the durability of archives, but also limits the use of modern advanced protection and restoration techniques, such as pulp fill-hole automation It does not apply to water-soluble ink writing files. Therefore, the ink must be reinforced before it can be repaired. Martine Leroy and Francoise Flieder after a lot of investigation and research, in the fixed ink has achieved satisfactory results. First, the choice of reinforcing agent Select the most suitable consolidating agent, we must consider the harmless to the paper this factor. A comprehensive analysis of Sandi’s products (Dermafix S, In-dosol E50 (50), Tergotan GS, Sandofix WE) and Bayer’s general product for dye reinforcement (Tanigan LD) 4). After a preliminary study, they screened four hardeners: X321, Indosol E50, Tanigan LD and Sandofix WE, determined the concentration of each hardener, the impregnation time and the optimal drying method, and examined the effect of treatment with bicarbonate Effect of Magnesium Removal on Strengthening.
