三类高强度悬式瓷绝缘子的成分和物相分析

A Study on the Chemical Compositions and Phases of High Strength Porcelain Insulator

为探讨高原牌 70kN和进口 12 0、2 10kN瓷绝缘子的成分和结构性能 ,文中采用原子吸收光谱 (AAS)和X射线衍射 (XRD)方法 ,对三类产品进行了检测。结果表明 ,有效成分除K2 O外 ,70kN和 2 10kN的SiO2 、Al2 O3 、Fe2 O3 含量接近。主晶相基本相同 ,有刚玉、莫来石、石英和长石等 ;结晶相总量 :70kN 35 %、12 0kN40 %、2 10kN 48% ,这表明机械强度愈大 ,结晶相含量愈高 ,只需调整 70kN原样的部分成分、粒度和工艺 ,即可生产出高等级 (如 2 10kN)

This paper introducd the research of high strength suspension porcelain insulator of 70kN,120kN and 210kN by the analyses of chemical compositions and XRD,the results showed that ① the major chemical compositions (%):70kN:SiO 2 52.30,Al 2O 3 39.52,Fe 2O 3 0.94,K 2O 3.88;120kN:SiO 2 62.36,Al 2O 3 31.70,Fe 2O 3 0.90,K 2O 1.99.②The major crystal-phase have corndum?mullite?quartz and potassium feldspar,etc.,their for relative contents 70kN 35%?120kN 40% and 210kN 48% respectively .③The raw materials of 70kN can be used to yield the insulators of 120kN or 210kN by adjusting part of chemical compositions,particle size and technology.
