引言海滨电厂凝汽器管,管外为过热蒸汽,管内为冷却海水,管材往往采用较耐海水腐蚀的铜合金,除此之外,还要用保护技术相配合。目前普遍使用的是硫酸亚铁成膜保护,在大量的文献中,对硫酸亚铁成膜(以下简称膜)的各种工艺作了较为详细的介绍,但对膜本身的微观性质探讨不多,本文则对膜进行了大量的测试分析,提供了膜的微观信息。金山热电厂6~#机组凝汽器,1978年9月在冷却海水入口端加入硫酸亚铁,1979年3月在加硫酸亚铁的同时,冷凝
Introduction Coastal power plant condenser tube, superheated steam outside the tube, the tube for the cooling water, the pipe is often more resistant to seawater corrosion of copper alloy, in addition, but also with the protection technology. At present, the commonly used ferrous sulphate film-forming protection has been described in detail in a large number of literatures for various processes of ferrous sulphate filming (hereinafter referred to as film), but the micro-properties of the film itself are not discussed In this paper, we carried out a lot of testing and analysis on the membrane and provided the micro-information of the membrane. Jinshan Thermal Power Plant 6 ~ # unit condenser, in September 1978 at the inlet of the cooling seawater added ferrous sulfate, in March 1979 with ferrous sulfate at the same time, condensation
