Background

The performance of the stirrer is directly related to the quality of the product, energy consumption and production cost. Common stirring occasions in industry include liquid-liquid mutual-soluble systems, liquid-liquid mutual-insoluble occasions, solid-liquid mixing occasions, and the like. For the case of liquid-liquid immiscible phases, it is often necessary to suspend or fully emulsify the immiscible liquid phase homogeneously, for example by extraction, emulsion polymerization and suspension polymerization in industry.
