摘要
结合热重分析仪的结构特点,研究了热重分析仪测定聚乙烯醇灰分的方法。研究表明:热重分析具有仪器性能稳定、自动化程度高的优点,显著缩短了分析时间,将测定时间由约8 h缩短为约30 min,提高了分析效率和工作效率。
Based on the structural features of thermal analysis, the determination of ash of polyvinyl alcohol by using Thermogravimetry Analyzer was conducted. The results showed that Thermogravimetry Analyzer had the property of stability and automation ,which largely shortened the analysis time from eight hours to thirty minutes to have improved analysis and working efficiency.
