偏二甲肼动态配气系统稳定性研究

Study on the Stability of the Dynamic Dilution System for Unsymmetric dimethyhlydrazine

采用分光光度法研究了偏二甲肼动态配气系统的稳定性。实验结果表明,在环境温度、载气温度和流量恒定的情况下,该动态系统可稳定地输出0～100mg/m^3的偏二甲肼标准气体,可用于肼类推进剂监测仪器的标定与校验;该配气系统还可用于制备用静态法难以配制其它极性化合物标准气体。

The stability of a dynamic dilution system for Unsymmetric dimethylhydrazine is studied by spectrophotometric method. It is shown that the dynamic Unsymmetric dimethylhydmzine dilution system can generate stable concentration in the range of 0-100 mg/m3 of Unsymmetric dimethylhydrazine vapor mixtures in a continuous manner. The system can be used to calibrate the monitoring instrument for propellant of hydrazine compounds. Other standard gases of polar compounds can also be generated by this dynamic dilution system.
