某博物馆空调冷热水管腐蚀失效分析

Analysis of Corrosion Failure of Air Conditioning Heat and Cold Water Pipes in a Museum

博物馆中的文物对环境有着特殊的要求,需要常年保持在恒温恒湿的环境中。中央空调系统在不间断运行的同时,还必须保证空调输水管不能出现腐蚀穿孔、腐蚀开裂等现象,一旦有水喷溅,将会对文物造成无法挽回的损失。利用宏观拍照、SEM,电化学等手段对一博物馆内的空调水管进行了腐蚀失效分析,重点对其对失效原因和机理进行研究,希望能为以后空调系统的安装与维护提供一定的参考。

Artifacts in museum have special environmental requirements for that they need to be preserved in a constant temperature and humidity environment all the year round. The appearance of corrosion perforation and corrosion cracking for the air conditioning pipes must be forbidden during the central air conditioning systems work, because the water splashing from the pipes may cause irreparable damage to artifacts. In this work, the corrosion failure behavior of air conditioning pipes in a museum was analyzed based on the use of macro-photographs, SEM, electrochemical and other means, and the reason and mechanism of failure were revealed at the same time. The results in the study are expected to provide a reference in the future for the installation and maintenance of air conditioning systems.
