Abstract

In this paper, the heat treatment of alumina fiber was studied. The infiltration agent on the fiber surface was removed after heat treatment at 450 °C for 6 h. TG-DSC, scanning electron microscope, x-ray diffraction, Fourier infrared spectrometer, energy dispersive spectrometer, and patterning were used to analyze the thermal weight loss, fiber surface morphology, crystal structure, and composition of alumina fibers. The results show that the aluminum oxide fiber has excellent temperature resistance and does not undergo crystal phase transformation during thermal weight loss. After heat treatment, the fiber surface infiltration agent ablates and dissolves from the fiber surface, and the internal crystal structure of the fiber remains stable. The tensile testing machine was utilized to test the breaking strength of alumina fiber. The fiber still maintained high strength after heat treatment, and the retention rate of breaking strength was greater than 74%. ZC-90G high insulation resistance measuring instrument and WDY-Ⅱ automatic voltage tester were utilized to analyze the insulation resistivity and breakdown strength of alumina fiber before and after heat treatment. The results show that heat treatment can effectively improve the insulation performance and breakdown strength of alumina fiber.

研究热处理对氧化铝纤维绝缘层的结构、机械和电气性能的影响
本文研究了氧化铝纤维的热处理。采用 TG-DSC、扫描电子显微镜、X 射线衍射仪、傅立叶红外光谱仪、能量色散光谱仪和图案分析了氧化铝纤维的热失重、纤维表面形貌、晶体结构和成分。结果表明,氧化铝纤维具有优异的耐温性,在热失重过程中不会发生晶相转变。热处理后,纤维表面的浸润剂从纤维表面烧蚀溶解,纤维内部晶体结构保持稳定。利用拉伸试验机测试氧化铝纤维的断裂强度。热处理后的纤维仍保持高强度,断裂强度保持率大于 74%。利用 ZC-90G 高绝缘电阻测量仪和 WDY-Ⅱ 自动电压测试仪分析了热处理前后氧化铝纤维的绝缘电阻率和击穿强度。结果表明,热处理能有效改善氧化铝纤维的绝缘性能和击穿强度。
