中文摘要:
      目的 研究钢制安全壳内外壁面无机富锌涂层在极限设计基准事故工况下的特性,为设计验证和非能动安全壳冷却系统热工水力试验边界条件的确定提供数据支持。 方法 参照大破口失水事故工况下可能形成的物理环境设计试验:试件置于恒温炉加热至 160 ℃ ,待整体温度均匀后,迅速浸入 20 ℃冷水中冷却,待冷却至常温后,再浸入 100 ℃沸水中加热 60 min。 测试涂层经过事故工况前后的导热性、干膜厚度、表面形貌和附着力,分析事故工况对这些性能的影响。 结果 模拟事故工况前后,涂层的干膜厚度在 70 ~130 μm 范围,附着力在 8. 5 ~ 13. 5 MPa 范围,热导率升高了 6. 8% ,表面形貌无明显变化。结论 模拟事故工况前后,涂层的干膜厚度、表面形貌和附着力无明显变化,涂层热导率有微升趋势。
英文摘要:
      Objective To investigate the characteristics of IOZ coating for passive containment after design basis accident, so as to provide data support to the design of passive containment. Methods The physical environment of test was designed refer to the working condition of the DBA:specimen in the thermostatic oven heated to 160 ℃ until temperature uniformity, then immersed in 20 ℃ water. After cooling to room temperature, the samples were immersed in 100 ℃ water for 60 minutes. The impact of DBA for coating was studied, and the main characteristics of the IOZ coating were thermal conductivity, dry film thickness, surface morphology, adhesion, etc. Results After the test, the DFT of the coating was 70 ~130 microns, the adhesion was 8. 5 ~13. 5 MPa, and thermal conductivity increases by 6. 8% , but the surface morphology was unchanged. Conclusion After DBA, the DFT, surface morphology and adhesion was unchanged, but the thermal conductivity was edge up.
