摘要
非蒸发物含量是评价在用有机热载体热稳定性的一个重要指标。本试验方法在现有测定非蒸发物含量方法基础上,规定了仪器的转速和真空泵的压力降速率,并考虑了试样温度的控制。试验结果表明,该试验方法符合有机热载体热稳定性测定方法中对非蒸发物含量测定的质量要求,有较好的重复性和较强的实用性。
The content of nonvolatile decomposition products is an important index for appraising thermal stability of organic heat carrier in use.This determination method specifies rotating speed of the instrument,pressure drawdown velocity of vacuum pump,and considers temperature control of samples on the basis of the existing methods.The results show that the method in this paper meets the quality requirements on content determination of nonvolatile decomposition products in thermal stability measurement of organic heat carrier and had good repeatability and practicability.
