For industrial polymerization production, the quality and production cost of polymers not only depend on the polymerization reaction process, but also on the structural type of the polymerization reactor. As an important polymerization reaction equipment, stirred tank reactors require professional selection and design to solve the problems of quality and energy transfer, resulting in excellent product performance and reduced production costs.
The design and engineering scaling up of stirred tank polymerization reactors have almost concentrated all the difficulties of stirred reactors, mainly including:
(1) The quality requirements for the product are high. For example, there are high requirements for product molecular weight, molecular weight distribution, average particle size, particle size distribution, particle morphology, etc;
(2) The complexity and variability of polymer systems. For example, heterogeneous systems, high viscosity non Newtonian systems, variable viscosity systems, etc;
(3) The complexity of flow in a stirred tank. For example, the randomness of three-dimensional flow, the complex shape of the agitator, and the difficulty in determining boundary conditions;
(4) The aggregation process has a significant thermal effect. The temperature control requirements for the reaction are strict, and the heat transfer elements and stirrers often require special design.
(5) Large scale aggregation equipment.
Yuanzheng Company has had many years of industry university research cooperation with Zhejiang University, and has gained valuable experience and theoretical guidance in polymerization reaction technology and equipment. They have successively developed various stirring equipment for polymerization processes and successfully applied them in industrial production.
