一种用于评估杆塔镀锌层表面腐蚀状态的检测方法
摘要：
本发明涉及一种用于评估杆塔镀锌层表面腐蚀状态的检测方法，属于杆塔镀锌层表面腐蚀状态的检测技术领域。本发明的检测方法，包括在被检测杆塔表面选择6处以上检测点；检测检测点的Fe、Zn质量含量；计算Fe/Zn比；根据获得的杆塔Fe/Zn比判断杆塔镀锌层腐蚀状态；当杆塔Fe/Zn比大于12%时，杆塔镀锌层为重度腐蚀，需及时进行防腐维护；当杆塔Fe/Zn比小于等于5%时，杆塔镀锌层为轻度腐蚀，杆塔无需防腐维护。相比于现有宏观检验根据经验判断杆塔镀锌层腐蚀状态，用该检测方法对镀锌层腐蚀状态进行评估更加客观、准确；相比于实验室微观分析，该方法可以方便、快速的判断出镀锌层腐蚀状态，易于执行。
摘要（英）：

The invention relates to a detection method for assessment of a corrosion state of the tower zinc coating surface and belongs to the technical field of detection of a corrosion state of the tower zinc coating surface. The detection method comprises selecting six or more detection points on the surface of a detected tower, detecting Fe and Zn mass contents of the detection points, calculating a ratio of Fe/Zn, and determining a corrosion state of a tower zinc coating according to the ratio of Fe/Zn, wherein if the ratio of Fe/Zn is greater than 12%, the tower zinc coating has a high corrosion degree and needs anti-corrosion maintenance and if the ratio of Fe/Zn is less than or equal to 5%, the tower zinc coating has a low corrosion degree and does not need anti-corrosion maintenance. Compared with the existing macroscopic examination method for determining a corrosion state of a tower zinc coating according to experience, the detection method provided by the invention realizes more objective and accurate assessment of a corrosion state of a tower zinc coating. Compared with laboratory microscopic analysis, the detection method can conveniently and fast determine a corrosion state of a tower zinc coating and can be executed easily.
