Study of Collection and Qualitative-Quantitative Method on Volatile Organic Compounds in Relay Material

Abstract

继电器内绝缘塑料件、漆包线的绝缘漆层在使用过程中或高温工作环境下产生的过量挥发性有机化合物是影响继电器可靠性的最重要因素之一。本学位论文根据企业实际需求建立了继电器材料中挥发性有机化合物的采集与分析定量方法,取得了以下成果: (1)运用顶空加热-气相色谱-质谱(HS-GC-MS)仪器联用系统建立了继电器材料中挥发性有机化合物的采集与分析定量方法。优化并确定了顶空进样针的加热温度、顶空加热炉加热样品瓶的温度、顶空加热炉加热样品瓶的时间、顶空样品瓶盖的隔垫、塑料米和漆包线样品量等关键分析条件。优化了顶空自动加热进样系统及气相色谱-质谱联用仪的载气流量、进样口温度、进样方式、色谱柱升温程序、检测器...The excess volatile organic compounds produced in the using process of the relay or high-temperature working environment in the insulation plastic parts and enameled wire insulating paint layer of relay is one of the most important factors affecting the reliability of the relay. In this thesis, a method for the collection and quantitative analysis volatile organic compounds in the relay based on t...学位:工学硕士院系专业:化学化工学院_工程硕士(化学工程)学号:X201119200
