Professionals such as Shen Jinzhou from the Coating Industry Research Institute of the Ministry of Chemical Industry introduced the operation of the high-speed disperser in his paper "Operation of the High-speed Disperser and Analysis of the Impeller": the first step, wetting operation; the second step, dispersion operation. In addition, the design principle of the high-speed disperser is also explained, and the high-speed disperser is more suitable for soft pigments and low to medium viscosity paints. It further introduces the impellers of the high-speed disperser, which are divided into disc impellers, sawtooth impellers, modified sawtooth impellers, multi-ring impellers, and constant shear impellers. The characteristics and advantages of the impellers are introduced respectively.
