Figure 6.2 is a comparative stable miniemulsion emulsifying apparatus at different time. When the same operating conditions, stabilization time miniemulsion prepared a high speed disperser, an ultrasonic cell crusher, and IS-RPB were 40 min, 51 min and 44 min, ultrasonic cell disruption mechanism seen stability of the emulsion prepared by the fine than sequentially IS -RPB and high-speed disperser. Analysis of the reasons, a high speed disperser rotor - stator structure, the periphery of the stator during emulsification liquid subjected to shear is weak, resulting in micro-fluid system membered suffered deviation; while the same amount of processing, ultrasonic cell crusher in cavitation, a sudden collapse of small bubbles have a great pressure so intense interaction between the micro liquid element, effectively improving high-speed disperser liquid infinitesimal discontinuity phenomenon.

Figure 6.2 shows a comparison of the stabilization time of fine emulsion under different emulsified devices. When the operating conditions are consistent, the fine emulsion stabilization time of high-speed disperser, ultrasonic cell crusher and IS-RPB preparation is 40 min, 51 min and 44 min respectively, and the stability of the micro-emulsion of ultrasonic cell crushing mechanism is better than that of IS-RPB and high-speed disperser. Analysis of its reasons, the high-speed disperser is the rotor-state structure, emulsified in the process of the peripheral liquid of the stator is weak shear force, resulting in the system of fluid microelements under the force is not uniform; The violent interaction between liquid microelements has been made, which effectively improves the phenomenon of uneven force of liquid microelements in high-speed dispersers.

Fig. 6.2 compares the stability time of miniemulsion under different emulsifying devices. When the operation conditions were identical, the stability time of miniemulsion prepared by high-speed dispersive cell, ultrasonic cell breaker and IS-RPB was 40 min, 51 min and 44 min respectively. The stability of miniemulsion prepared by ultrasonic cell disruption was superior to that of IS-RPB and high speed disperser. The reason is analyzed. The high-speed disperser is of rotor stator structure. In the process of emulsification, the liquid around the stator is subject to weak shearing force, resulting in uneven force on the fluid micro elements in the system. However, under the same processing capacity, the sudden collapse of small bubbles in the ultrasonic cell crusher under the effect of cavitation will generate great pressure, which will cause violent interaction between the liquid micro elements and effectively improve The phenomenon of uneven force on the liquid micro element in the high-speed disperser is improved.
