Swiss LIST's newly developed new reactor is suitable for the polymerization of various high molecular polymers, especially polycondensation and bulk polymerization. This uniquely designed stirred polymerization reactor has the following characteristics:
Equipped with strong stirring power to ensure that materials of all viscosities can be fully and uniformly mixed, and can handle materials with a viscosity of up to 40'000 Pa ， s;
The jacketed housing, hollow stirring blades, and shaft can be heated or cooled by a thermally conductive medium. Therefore, the heat transfer area per unit volume of the reactor is large, which can more effectively transfer heat and accurately control the reaction temperature;
The scraper installed on the top of the stirring paddle makes the reactor have the function of self-descaling, so as to ensure that there is no dead angle and no sticky wall phenomenon in the equipment, and the heat transfer coefficient is improved;
High surface renewal rate of materials, which improves the mass transfer rate and speeds up the removal of low molecular components;
The reactor can be operated continuously, the axial back mixing is small, and the flow condition is close to the flat push flow;
The equipment has a large volume (maximum effective volume can reach 10,000 liters), which can complete slow processes that require long residence times, and can also achieve multiple unit operations (such as mixing, reaction, degassing and drying) in one device at the same time , Saving space, energy consumption and equipment investment.
The LIST polymerization reactor is suitable for the industrial production of a variety of polymers, such as super absorbent resin (also called water-retaining agent, polyacrylate), silicone resin, polycarbonate (PC), syndiotactic polystyrene (SPS), Polydimethylsiloxane (PDMS), polylactic acid (PLA), hexamethylolmelamine, polystyrene, melamine resin, polyamide, polyester, etc.
In addition to polymerization, LIST equipment can also be used in many other fields, such as direct solvent removal of synthetic rubber, mixing, evaporation and drying of polymer materials, and various baking reactions.
