在传统的档案修裱技术中,水有着十分复杂的作用:它是淀粉胶料的溶剂,也是档案纸张上各种可溶物质的溶剂;是纤维的润胀剂,纸的增塑剂;还是档案纸张与托纸之间的润滑剂。修裱浆糊的含水量高达90％以上,湿托时档案纸张的含水量可超过40％。揭档案砖时还要把整个档案浸入水中或由水蒸气熏蒸。在整个修复过程中,水使档案纸张及纸上的其它物质发生着化学的或物理的变化。通过研究水在其中的作用,可了解水对修裱质量、对档案原件耐久性所新产生的影响,从而确定由此产生的对修裱技术的要求。一、水的溶剂作用(一)水在浆糊中的溶剂作用。传统的修裱技术,是通过浆糊把选定的纸补或托在档案原件上,使破损的部分当托纸与档案纸以一定的牢固度相粘合,并成为一个整体时,原件的强度才得以提高。要做到这一点,浆料的流动性好不好是关键。含水量高的稀浆糊具有很好的流动性,上浆时能均匀地分布在纸页的各个部位,并容易渗透到纸张纤维中去,从而使原件与托纸共同形成一个无缺陷的整体,保证了修裱件较长的使用寿命。
Water has a very complex function in traditional archiving techniques: it is a solvent for starch compounds, a solvent for various soluble substances on archival paper, a bulking agent for fibers, a plasticizer for paper, or Lubricant between archive and supporting paper. Boring paste the moisture content of up to 90% or more, wet care when the water content of the file can be more than 40% of the paper. When you open a file, you also need to immerse the entire file in water or fumigate with water vapor. Throughout the restoration process, water chemically and physically changes the archive paper and other materials on the paper. By studying the role of water in it, we can understand the impact of water on the quality of the mounting, and the new durability of the original file to determine the resulting requirements for mounting technology. First, the role of water solvents (A) water in the paste solvent effect. The traditional mounting technique is that the selected paper is padded or supported on the original file by paste so that when the damaged paper is bound to the file with a certain degree of firmness and becomes a whole, Strength can be improved. To do this, the mobility of the slurry is good or not is the key. Slurry with high water content of the paste has good mobility, when the sizing can be evenly distributed in various parts of the paper, and easily penetrate into the paper fiber to go, so that the original and the supporting paper to form a complete defect-free, Ensure the repair of pieces of a longer service life.
