军用涂层海洋大气自然环境试验方法与要求
|
摘要
综述了军用涂层海洋大气自然环境试验方法与要求。自然环境试验可较好地反映涂层在湿热海洋大气中受高温、高湿、高盐雾、强太阳辐射的长期综合作用效应。提出了军用涂层海洋大气自然环境试验设计要求,介绍了常见的海洋大气自然环境试验方式,对涂层自然环境试验的设计与开展具有指导性和实用性。最后,探讨了军用涂层海洋大气自然环境试验存在的问题,提出须提高认识,将自然环境试验作为一项长期系统工作,形成良性的"迭代式"发展模式,指出自然环境加速试验是军用涂层自然环境试验的重要发展方向。
Test methods and requirements on military coatings in marine atmosphere natural environment were summarized in the paper. The long-term and comprehensive effect of high temperature, high humidity, high salt fog and solar radiation on the coating in the humid and hot ocean atmosphere can be better reflected through the natural environment test. The design requirements on marine atmosphere natural environmental test were proposed, and the common test methods of marine atmosphere natural environment were introduced, which were instructive and practical for the design and development of natural environmental test for coatings. Finally, the existing questions of marine atmosphere natural environmental test for military coatings were discussed. It was proposed that it was required to improve the understanding, take the natural environmental test as a long-term system work and form a virtuous "iterative" development model. It also pointed out that the natural environmental accelerated test was an important development direction of natural environmental test of military coating.
