Why can ethylene glycol chillers be used for polymerization and coupling reactions

1. Polymerization heating

Generally, the raw materials of polymerization reaction are some flammable solvents, and heating up quickly may cause local temperature to be too high and cause accidents. Every polymerization reaction has its proper reaction temperature. If the temperature is changed outside, the reaction efficiency will be reduced, and the polymerization reaction will release more reaction heat. Changing the proper temperature will be immeasurable, especially in industrial production. accident. Therefore, Wuxi Guanya's refrigeration and heating integrated machine can be selected to adjust the temperature of the polymerization reaction to ensure the safety in the process of production.

Among the polymerization reactors, more than 80% of the polymerization reactors are tank reactors. There are two types of reactors without stirring and those with stirring. Among them, the reactor with stirring is used more. Because the heat exchange device has endothermic and exothermic reactions, it is necessary to set up a heat exchange device to provide and take away heat. The main structure is With jacket heat transfer, inner cooling part heat transfer and external circulation heat transfer, Wuxi Guanya's refrigeration and heating equipment can just meet the regulation of exothermic and endothermic heat.

The kettle type polymerization reactor can be used for the production of a variety of polymers; it can be used in low-viscosity polymer systems as well as high-viscosity polymer systems; it can be used in both batch operation and continuous operation. The basic structure of the polymerization reactor mainly includes a kettle body, a stirring device, a stirring accessory, a heat transfer device, and a sealing device. According to the reaction materials and operating requirements, the kettle type polymerization reactor has a variety of types, such as thin and long type and short and fat type, which are mainly determined by the ratio of length to diameter.

2. The characteristics of the coupling reaction

The coupling reaction rate is slow, and the solubility of the reaction product often changes greatly. After precipitation, the viscosity of the material is greatly increased, which seriously affects the mixing of the material, and is easy to form a material package and cause the reaction to be incomplete. The application of the microchannel reactor to the coupling reaction enhances the mixing of materials and is beneficial to increase the reaction rate. It is equipped with high and low temperature integrated equipment. When the reaction temperature is in the range of 5-25, as the temperature rises, the reaction rate increases, and the residence time required for the complete reaction becomes shorter, but at the same time, the low flow rate is The reaction will accelerate.

The dynamic temperature control of LNEYA glycol chiller is mainly used in dynamic constant temperature control of high pressure reactor cold and heat source, dynamic constant temperature control of double-layer glass reactor cold and heat source, dynamic constant temperature control of double-layer reactor cold and heat source, constant temperature of microchannel reactor Control; small thermostat control system, steaming system temperature control, material low temperature high temperature aging test, combined chemical cold source heat source constant temperature control, semiconductor equipment cooling heating, vacuum chamber cooling heating constant temperature control.
