书写材料花色品种繁多的今天,人们往往只注重书写的流利性、书写材料的外包装,而忽视字迹材料的耐久性。以目前社会通行的看法,碳素墨水与蓝黑墨水是公认的档案书写材料。碳素墨水的主要色素成分是碳黑,其分子结构是由众多乙烯基(发色团)通过大π键共轭而成的巨大片层结构。量子力学研究证明,具有这种结构的体系能量低,化学性能稳定。所以,碳素墨水的耐久性是毋庸置疑的。但是,由于碳黑在使用过程中,碳素墨水易发生堵笔现象,很多单位和个人更愿
Today, people tend to focus on the fluency of writing and the packaging of writing materials, while ignoring the durability of writing materials. At present, the prevailing social view, carbon ink and blue ink is a recognized file of writing materials. The main pigment component of carbon ink is carbon black, and its molecular structure is a huge lamellar structure formed by the conjugation of a large number of vinyl groups (chromophores) through a large π bond. Quantum mechanics research shows that the system with this structure has low energy and stable chemical property. Therefore, the durability of carbon ink is beyond doubt. However, due to the use of carbon black in the process of using carbon ink prone pen stuck phenomenon, many units and individuals prefer
