Slurry system is a multiphasesystem in which one substance is dispersed in another substance at a certainsize. There is a clear phase interface in the system. It is widely used in the variousfields. From the view of traditional chemical process, the slurry system alsocovers the basic chemical processes such as raw material refining, preparationand functionalization, separation, etc. There are many chemical processes withgreat value such as heterogeneous catalysis and sedimentation filtration. Considering the phase interface inthe slurry system, if the phase interface could be reasonably regulated, itsinherent advantages will be fully utilized. For example, in the process offlotation, separation is achieved by utilizing the inherent differences in thehydrophilic and hydrophobic properties of the interface between different solidparticles in the system. In the reaction process of emulsion polymerization,the types and amount of emulsifier are adjusted to realize the production oflarge-scale polymers by controlling the phase interface in the heterogeneoussystem. In the process of heterogeneous catalysis, efficient interfaces areprovided for the reaction through the fine design of the catalyst surface, whichimproved the reaction efficiency greatly. Combining these typical chemicalprocesses, it is found that no matter bottom-up (using the interface structureto realize the nano-level controllable reaction), or bottom-down (usinginterface action to achieve micron-level controllable separation of solidmixtures) construction of interface and regulation of multiphase systems are of great significance to realize the intensification of the process.
