【摘要】：山东济南魏家庄遗址出土铁质文物中含有大量有害氯离子,严重威胁着文物的安全。因此,脱盐就成为该批铁器保护的重点,是阻止铁器继续腐蚀的重要保证。在经一系列实验工作后,该批铁器的脱盐溶液采用0.005mol/L NaOH溶液,对于仅为铁质的容器类铁器采用直接浸泡法,同时结合冷热交替和超声波法;对于带有鞘的兵器类铁器采用2%Primal AC33加固后再进行脱盐;对于带有漆皮痕迹的铁器也试用了纸浆脱盐法。铁器经脱盐后氯离子含量大大降低,脱盐取得了很好的效果。
[Abstract]:The iron relics unearthed in Weijiazhuang, Jinan, Shandong province contain a large number of harmful chloride ions, which seriously threaten the safety of the relics. Therefore, desalination has become the focus of protection of this batch of ironware, and it is an important guarantee to prevent the corrosion of the ironware. After a series of experimental work, the desalination solution of this batch of ironware is 0.005mol/L NaOH solution, and the direct immersion method is used for the vessel iron-like vessel which is only iron, at the same time, combined with the alternation of cold and heat and ultrasonic wave method; 2%Primal AC33 was used to reinforce the weapon-like ironware with sheath and then desalination was carried out, and the pulp desalination method was also used for the ironware with lacquer skin trace. After desalination, the chloride ion content of the iron vessel decreased greatly, and the desalination effect was very good.
