摘要

摘要D5(十甲基环五硅氧烷)是一种蒸发缓慢的非极性溶剂,测试了其作为正在进行水处理的纸张上的水敏介质的临时掩蔽剂的适用性。在五种不同的纸张类型上测试了三种不同的处理相关设置,其中一些是用水溶性油墨制备的。在10分钟的水浸渍处理中,D5被证明在很大程度上不能保护水溶性油墨。结合环十二烷的熔融应用,D5的加入仅在一种情况下增强了其阻隔功能。为了测试D5防止潮线形成的能力,测试样品接受了水、丙酮和水-乙醇混合物的应用,形成了与新的D5浸渍区域的界面。对纸张进行视觉评估(VIS、UVA),有些是在人工老化后进行的。D5减少了在与丙酮和乙醇-水混合物接触的具有低吸水性的两种内部尺寸纸张中可见潮线的形成,但没有阻止潮线与水接触。它也不能保护吸水纸。结果表明,与乙醇和丙酮混溶的D5可以分散这些溶剂引起的潮线,但在浸水过程中,它在很大程度上不足以保护介质。

Cyclopentasiloxane (D5) as a Non-Polar Masking Agent for Water-Sensitive Substrates During Polar Solvent Treatment
Abstract D5 (decamethylcyclopentasiloxane), a non-polar solvent that evaporates slowly, was tested for its suitability as a temporary masking agent for water-sensitive media on paper objects undergoing aqueous treatment. Three different treatment-related settings were tested on five different paper types, some prepared with water-soluble inks. In 10-min water immersion treatments, D5 proved largely ineffectual in protecting the water-soluble inks. In conjunction with melt-applications of cyclododecane, the addition of D5 enhanced its barrier function only in one case. To test the ability of D5 to prevent tideline formation, the test samples received applications of water, acetone, and a water-ethanol-mixture, creating an interface with freshly D5-impregnated areas. The papers were evaluated visually (VIS, UVA), some after artificial aging. D5 diminished the formation of visible tidelines in the two internally sized papers with low water absorbency in contact with acetone and the ethanol-water mixture, but did not prevent tidelines in contact with water. It also did not protect water-absorbent paper. The results indicate that D5, which is miscible with ethanol and acetone, may disperse tidelines caused by these solvents, but it proved largely insufficient for protecting media during water immersion.

期刊介绍: Restaurator is the only international periodical specializing exclusively in the conservation of library and archive materials. Articles examine the many important aspects of this subject area, such as technology, practical experience and organization. They also focus on scientific basics: Many articles deal with the development of new preservation techniques and the improvement and better understanding of established methods. The articles are written in English with summaries in English, French and German. By reading Restaurator regularly, librarians, archivists and restorers can keep up to date with the latest research and developments. The editorial committee is made up of experts from well-known institutions and organizations from all over the world
