丁苯胶乳中的橡胶组成通常采用硝化法、碳氢法及折光指数法测定。近年来随着热裂解气相色谱法的发展,已使该方法能应用于橡胶组成的定性或定量分析。 硝化法、碳氢法及折光指数法所使用的仪器设备及操作步骤繁杂,分析的周期也较长,不能满足工业分析的快速要求。 热裂解气相色谱法,不仅在精确性方面达到要求,而且具有操作简便、分析时间周期短的优点。
The rubber composition of SBR latex is usually measured by nitrification method, hydrocarbon method and refractive index method. In recent years, with the development of pyrolysis gas chromatography, the method has been applied to the qualitative or quantitative analysis of rubber composition. Nitrification method, hydrocarbon method and refractive index method used by the equipment and operating procedures complicated, analysis of the cycle is longer, can not meet the rapid industrial analysis requirements. Pyrolysis gas chromatography, not only in terms of accuracy to meet the requirements, and has the advantages of simple operation, short analysis time cycle.
