| 目的 通过监测得到高湿热、高盐雾的海洋大气环境下不同局部环境的数据，并对不同材质、结构和部件针对性地提出防腐需求。方法 开展温度、湿度、盐雾沉降率的监测以及高精度测试片、标准试验件的腐蚀试验，分析1年时间内湿热盐雾海洋大气环境不同工作环境下监测参数的趋势，研究不同局部工作环境下各时间段的腐蚀性，进行环境评估分级。结果 海南某濒海区域常年高温、高湿、高盐雾，根据两种试验方法判断，该区域大气腐蚀等级达到了最严酷的等级(CX或GX)。室内大厅和机房环境也是长期高温、高湿，明显可检测到海盐粒子，高精度测试片有腐蚀现象，但与室外严酷环境至少相差1个等级。室内机电控制柜内环境腐蚀等级一般为G1，温度相对较高、湿度相对较低。结论 可根据不同使用环境防腐需求制定防护方案，既能满足长期防腐和设备稳定运行的要求，又能避免过度防护，合理有效地利用资源，节约成本。 |

| To obtain the data of different local environments in the marine atmospheric environment with high damp and heat and high salt spray through monitoring, and put forward anticorrosion countermeasures appropriately for different materials, structures and components, this paper carries out the monitoring of temperature, humidity and salt spray sedimentation rate as well as corrosion tests of high-precision test pieces and standard test pieces. The trend of monitoring parameters under different working environments in damp and hot salt spray marine atmospheric environment within one year is analyzed. And the corrosivity of different periods under different local working environments is studied to carry out environmental assessment and classification. The research shows that the atmospheric corrosion level of a coastal area in Hainan has reached the severest level (CX or GX) according to two test methods, which are high temperature, high humidity and high salt spray all year round. The indoor hall and machine room environment are also high temperature and humidity for a long time. Sea salt particles can be obviously detected. The high-precision test piece has corrosion phenomenon, but it is at least one grade different from the harsh outdoor environment. The level of environmental corrosion in the indoor electromechanical control cabinet is generally G1 with relatively high temperature and relatively low humidity. So protection schemes can be formulated according to the anti-corrosion requirements of different use environments, which can not only meet the requirements of long-term anti-corrosion and stable operation of equipment, but avoid over-protection to reasonably and effectively utilize resources and save costs. |
