Monitoring acid value and flashing point and increasing detecting period of severity of wear index can lower the monitoring cost. 因此,为降低油液监测成本,可以选取酸值、闪点进行检测,并延长磨损烈度指数的检测周期。
Different determination methods for flashing point should be adopted to meet the different petroleum products. 闪点可分为闭口闪点和开口闪点,根据石油产品种类的不同采取不同的方法测定闪点。
With the established model, the boiling point and flashing point of the other 7 halogenated benzenes were predicted. 利用建立的模型,对另外7种卤代苯的沸点和闪点进行了预测。
The calculated results showed that the calculated boiling point and flashing point of halogenated benzenes and halogenated benzaldehydes were in good agreement with the experimental data with mean deviation of 2.73 ℃ and 6.32 ℃. 对卤代苯和卤代苯甲醛的沸点和闪点的计算结果表明,计算值与实验值的一致性令人满意,平均误差分别为2.72℃和6.32℃。
The discussion on the standard test methods for determination of petroleum products flashing point 石油产品闪点测定方法的探讨
The insulation oil has low viscosity, low freezing point, high flashing point, high crushing strength and stability excellent features. 具有粘度小、凝固点低、闪点高、耐压强度大及稳定性好等优良特性。
