近年来,玻璃钢在耐腐蚀领域中应用日趋广泛。同时,出现了一些值得注意的问题,如整体玻璃钢设备及管道的渗漏、“冒汗”;如何确定玻璃钢衬里的厚度;预估玻璃钢的使用寿命等等。这些实际问题都与介质向玻璃钢扩散、渗透的行为密切相关。另一方面,从腐蚀机理来看,无论是化学腐蚀或物理性的膨胀破坏,其发生原因都系以介质向材料内部进行扩散、渗透为前提,这也是高分子材料与金属材料腐蚀机理的主要区别。随着介质向材料内部的扩散、渗透,材料的外观、物理机械性能及电性能等均会发生变化,特别对玻璃钢来说,树脂—纤维界面的粘结状况也必然发生变化。因此,扩散、 In recent years, FRP has become more and more widely used in the field of corrosion resistance. At the same time, there are some notable issues, such as the overall leakage of FRP equipment and pipes, “sweating ”; how to determine the thickness of FRP lining; estimated FRP life and so on. These practical problems are closely related to the media’s diffusion and infiltration into FRP. On the other hand, from the corrosion mechanism point of view, whether it is chemical corrosion or physical expansion and destruction, its reason is to the media to the internal diffusion, penetration of the premise, which is the main mechanism of polymer materials and metal corrosion the difference. With the media to the material’s internal diffusion, penetration, material appearance, physical and mechanical properties and electrical properties will change, especially for FRP, resin - fiber interface bonding conditions are bound to change. Therefore, proliferation,
