桥接

桥接是什么意思？

桥接是一个可见的涂层缺陷发生的due to insufficient surface preparation or an improper coating application on a metal surface with the intention of preventing corrosion. It is characterized by gaps on the metal substrate's surface that have been filled with a coating or other fluid.

腐蚀解释了桥接

桥接是带有涂层的未填充间隙，裂缝或角关节的覆盖，由于分子间和结构性不连续性，这引起了油漆膜的弱点。

可以通过仔细评估所有油漆成分的化学成分并了解它们对给定的固化温度的反应来防止桥接。高粘性油漆系统往往会增加桥接的可能性。

我n the event of bridging, the applied coating should be removed, the gap filled and then the coating reapplied on a more uniform surface.
