通过对不同尺寸,充水和空气的预设缺陷,在不同时间段进行红外热成像检测对比试验,研究红外热成像技术检测抹灰砂浆缺陷的有效性和影响因素,研究结果表明,红外热成像技术对含空气的空鼓缺陷的检测是有效的;空鼓面积和厚度越大,效果越明显;最适合的检测时间段是在早上环境温度上升过程中。 Through contrasting the infrared thermal imaging test at different time, the paper studies the effectiveness and influencing factors of the infrared thermal imaging technology detecting the defects of the plastering mortar. The results show that infrared thermal imaging The technique is effective for the detection of hollowed-out air-bearing defects; the greater the hollowed-out area and thickness, the more pronounced the effect; the most suitable detection period is during the morning ambient temperature rise.
