摘要
在设计出水链形成及消散时间测量装置的基础上,对于脉冲电破乳过程和机理进行了较深入的分析,建立起水链消散过程的理论模型,为脉冲电破乳之频率选择提供了可靠依据。实验结果表明,对于具有较高含水量的W/O乳状液的破坏,采用高压、低频、窄脉冲电场效果最佳.这对于脉冲电破乳的实际应用具有较重要的指导意义.
Based upon the measuring methods of formation amd dissipation time of drops chains, the mechanism of demulsification is discussed in some detail and a theoretical model is developed to account for the dissipation process of the chains, which will provide a reliable basis for choosing a suitable pulsed frequency. The experimental results show that the emulsions with a high phase ratio can be more efficiently separated by use of a high voltage, low frequncy and narrow pulsed field, which is important for applying pulse electric demulsification in practice.
