The authors pointed out that in condition of high RH, pollution air and outdoor, the corrosion of Amillary sphere and Aoridged Amilla is a dynamic accelarated corrosion. The complex environment and the remaining of the patina increase the complexity of protection technology. It is imposible to realize effective protection by using common materials and technologies. So, authors of this paper synthesized N, N-di (Benzotriazol-Methylene ) Lauryl Amine to compound synergistic inhibitor cluster,and synthesized...

The authors pointed out that in condition of high RH, pollution air and outdoor, the corrosion of Amillary sphere and Aoridged Amilla is a dynamic accelarated corrosion. The complex environment and the remaining of the patina increase the complexity of protection technology. It is imposible to realize effective protection by using common materials and technologies. So, authors of this paper synthesized N, N-di (Benzotriazol-Methylene ) Lauryl Amine to compound synergistic inhibitor cluster,and synthesized Methacrylate resin modified by organosilicon to compound seal agent with synergistic stabilizing agent. With these materials and the technology of protection affer dehydration, the corrosion rate of the instruments protected with patina can reduce to lower than that of them in non-polluted air.In this paper, the authors estimate the practicability of the technology by electrochemical method,and discuss the relationship between material characters and corrosion environment,and the relationship between material characters and protection with patina according to the result of ageing test at artificial climate. The authous also research the reasons why N,N-di (Benzotriazol-Methylene)Lauryl Amine is more proper to be used in the protection of the instruments than BTA by XPS.

浑仪、简仪(以下简称两仪)在高PH、大气污染和日晒雨淋环境中的腐蚀是一种动态加速腐蚀过程。采用合成的双唑胺铜缓蚀剂和有机硅改性的甲基丙烯酸树脂,并分别复配成协同缓蚀剂群和含有增效稳定剂的封护剂。采用这两种材料和脱水后再防护的工艺,使带锈防护后的浑仪、简仪的腐蚀低于无污染大气中的速率。用电化学方法评价了防护技术的可行性,根据腐蚀与人工老化试验结果讨论了防护材料性能与腐蚀环境和带锈防护的关系,采用XPS分析方法探索了双唑胺比BTA更适用于两仪防护的原因。
