The multifunctional decentralized reactor has the functions of low speed, strong stirring and high speed dispersion, and has good adaptability to medium high viscosity and thixotropic materials. Because of mixing, dispersing can be carried out at the same time and ideal results can be obtained. The machine is suitable for mixing all kinds of materials, dissolving and dispersing and painting, with simple operation and strong adaptability. It is an ideal multi-functional equipment such as mixing, dispersing and so on.
