【摘要】：为研发新型的涂层检测方法,本文在分析和研究现阶段涂层质量检测技术的基础上,通过对输电线路绝缘子RTV涂层施涂质量的抽检实验,提出一种新型且适用于非金属基体表面涂层质量的检测方法——敲击测声法,用于基体为陶瓷、玻璃等高硬度材料,涂层为橡胶等低硬度材料的质量检测,可以保证在不损伤被测涂层的情况下检测涂层厚度、均匀度等质量指标。当基体与涂层有较明显硬度差别时,通过相同力度敲击被测涂层表面,检测返回的声强峰值(即分贝数值),判断非金属基体表面涂层质量的差异,并在检测软件Wensn Sound Link界面实时显示检测数据的变化,直观地反映检测结果。此方法对航天、电力、机械制造等多个领域的涂层检测具有良好的推广应用价值。
[Abstract]:In order to develop a new coating testing method, based on the analysis and research of the current coating quality testing technology, this paper makes a sampling test on the coating quality of the insulator RTV coating of transmission lines. A new method for measuring the quality of coatings on nonmetallic substrates is presented, which is used to detect the quality of low hardness materials such as ceramic, glass and rubber. The quality indexes such as thickness and evenness of the coating can be determined without damaging the tested coating. When the hardness of the substrate and the coating is obviously different, the surface of the tested coating can be struck with the same force. The peak sound intensity (i.e. decibels value) returned from the detection is used to judge the difference of coating quality on the surface of nonmetallic substrates, and the change of detection data is displayed in real time at the interface of Wensn Sound Link, which directly reflects the test results. Coating detection in many fields, such as mechanical manufacturing, has a good value of popularization and application.
