摘要
为了测定胶体四氧化二氮的饱和蒸气压,找出其在不同温度条件下的变化规律,采用静态法测试原理,自行设计建立了四氧化二氮胶体饱和蒸气压的测试装置,测得了常压下液体和胶体四氧化二氮的饱和蒸气压数据,结果表明,四氧化二氮体系成胶后比成胶前的饱和蒸气压略有降低,且温度越高其差值越大。从理论上分析了两种胶凝剂对四氧化二氮体系饱和蒸气压的影响作用,从而推导出了四氧化二氮胶体饱和蒸气压的理论计算公式,计算误差小于5%,可依据该公式对四氧化二氮胶体在不同温度条件下的饱和蒸气压进行估算。
In order to determine the saturated vapor pressure of colloided dinitrogen tetroxide, and find out its change rule with the various temperature, a testing equipment of determining satuated vapor pressure of colloided dinitrogen tetroxide was designed and constructed according to the principle of static testing. The saturated vapor pressure of liquid and colloided dinitrogen tetroxide under the normal pressure at several temperatures was obtained. The results show that the saturated vapor pressure Of colloided dinitrogen tetroxide was lower than that of liquid dinitrogen tetroxide. With increasing temperature of sample, the gap of the saturated vapor pressure of dinitrogen tetroxide from liquid to colloid increases. The influence of two gallants on the saturated vapor pressure of colloided dinitrogen tetroxide system was analyzed, and a theoretical formula of estimating the saturated vapor pressure of colloided dinitrogen tetroxide was derived. The estimated error of the formula is lower than 5 percent, so the saturated vapor pressure of colloided dinitrogen tetroxide on the various temperature condition could be estimated according to the theoretical formula.
