摘要:
为缩短化学品遇水反应释放易燃气体的检测时间，提高化学品危险性鉴定效率，在联合国《关于危险货物运输的建议书-试验和标准手册》化学品遇水反应危险性检测方法的基础上，以超声波水浴代替传统的电加热水浴，研究了不同频率超声波对加速化学品遇水反应释放易燃气体速率的影响，考察了超声波对不同粒径镁硅铁、硅铁、高纯硅铁、铝粉、锌粉以及镁粉遇水反应释放气体速率的加速规律，建立了超声波法检测结果与标准实验方法检测结果的等效加速方程。研究表明，超声波方法可以有效的促进化学品遇水反应释放易燃气体的速率，45kHz为最佳超声频率，将遇水反应危险性检测时间由原来的7h缩短至1h；当化学品粒径小于240目与大于240目时，超声波对其遇水反应释放易燃气体速率的影响不同，等效加速方程充分考虑了超声波对不同粒径化学品的促进规律，使得超声波法能够与标准实验方法实现良好等效。
Abstract:
To improve the detection velocity of flammable gas released by chemicals in contact with water and improve chemical hazard identification efficiency, ultrasonic method was used to test the velocity of chemical reacting with water and emitting flammable gas instead of electric heating bath method in the United Nations Recommendations on the transport of dangerous goods  Manual of tests and criteria. The ultrasonic method shortened the hazardous detection time from 7h to 1h. The influence of 80kHz, 100kHz and 45kHz ultrasonic wave frequency on the acceleration of in contact with water process were investigated, and the optimum ultrasonic wave frequency of 45kHz was determined. The influence of different ultrasonic wave frequency the acceleration of velocity which chemical reacting with water emitting flammable gas was investigated, the optimum ultrasonic wave frequency of 45kHz was determined. Different particle size of ferrosilicon magnesium, ferrosilicon, high purity ferrosilicon, aluminum powder, zinc powder and magnesium powder were investigated to find the influence of ultrasonic wave to acceleration of velocity. The equivalent acceleration laws of ultrasonic method to standard method were established, and when the particle size was lower or higher than 240mesh, the equivalent accelerate equations were different. So different equivalent accelerate equations were established to make the results conversion more accurate.
