| 摘 要： | 目的考察圆珠笔字迹油墨厚度对溶剂挥发速率的影响。方法采用GC/HPLC联用技术对不同时间、不同字迹油墨厚度在同种纸张上的圆珠笔油墨字迹中的溶剂、染料成分的定量分析。结果字迹油墨较厚的苯甲醇、苯氧基乙醇的含量随时间的变化比字迹油墨较薄的慢。结论字迹油墨的厚度对溶剂的挥发速率影响较大。

| Abstract: | In this paper,effect of ink thickness of ballpoint pen stroke on solvent evaporative rate was studied by GC and HPLC.Results revealed that the evaporative rate of benzyl alcohol and Phenoxy alcohol varied with the ink thickness of strokes. Therefore the ink thickness of stroke is an important factor for ink age determination. |
