The mixing conditions to be set for the reaction vessel design include the tank volume, tank type, properties of the material inside the tank, mixing purpose, operating temperature and pressure, whether it is batch or continuous operation, etc. Undoubtedly, this is the foundation for designing mixing equipment, usually provided by the equipment supplier. However, for some items, users often cannot specify them precisely and need to communicate with the designer to determine them, particularly for the properties of the material and the mixing purpose. For example, for non-Newtonian fluids like polymer melt, the viscosity in the operating state is related to the shear rate, which in turn is related to the type and speed of the agitator.;And as for the solid...-Liquid suspension, gas-In liquid dispersion operations, the designer of mixing equipment needs the user to specify the required level of mixing intensity, which often necessitates coordination and communication between the designer and the user.zuiBoth parties have confirmed the mixing conditions.
