目前,市场上航空产品清洗剂种类繁多,质量参差不齐,且大部分控制剂仅进行过诸如清洗效率、腐蚀性、与非金属材料相容性、贮存稳定性、外观、闭口闪点、pH值、黏度、乳化性等实验室理化性能测试,而较为缺乏真实外界环境试验鉴定考核结果。尤其是对于南海、远海等恶劣环境条件地区,航空产品会遭受高温、高湿、高盐雾等恶劣环境因素的综合影响,未经实际试验而盲目选用不恰当的腐蚀控制方法,易导致航空产品出现“欠保障”或“过保障”问题,带来安全隐患,给机务维护工作带来极大不便。本文以典型航空材料铝合金为研究对象,选取国内市面上几款典型的清洗剂,以清水清洗为对照,对其在南海海洋大气环境下的清洗效果进行试验评价,探索不同清洗剂对民用航空器关键材料腐蚀损伤的影响。 相似文献

The main purpose of this study was to develop a set of measures for evaluating the performance of the automobile green supply chain. This study reviewed various literatures on green supply chain performance measurement, environmental management, traditional supply chain performance measurement, and automobile supply chain management. In order to comprehensively and effectively establish the relevant measures, a suitable framework which considered the automobile green supply chain as a two-in-one chain was adopted. This two-in-one chain comprised a forward and backward chain for the automobile industry. Consequently, 10 measures with 49 metrics and 6 measures with 23 metrics were identified and developed for the forward and backward chains, respectively. Sequel to the development of these measures, a survey was conducted using a four-page questionnaire distributed to experts (including academics and practitioners) to establish their importance and applicability. The findings of this study suggested that the importance and applicability of all the developed measures have been substantiated. For the forward chain, the most crucial measure was customer perspective while the most applicable one was traditional supply chain cost. The reverse chain measures were topped by management commitment in terms of both importance and applicability. This study contributed to the advancement of knowledge by pioneering the development of a set of holistic measures for evaluating the performance of the automobile green supply chain. The study was wrapped up with the proposition of directions for further studies. 相似文献
