AI Technical Summary
Traditional stirring devices are prone to creating dry stirring and dead zones in the production of high-viscosity polysulfone, resulting in uneven material mixing and low heat transfer efficiency.
By employing the differential counter-rotation of the central shaft and the sleeve, combined with shearing plates and scrapers, and in conjunction with the crushing mechanism, it achieves strong shearing, tumbling, and mixing of high-viscosity materials, preventing dead zones in the mixing process, and improving heat transfer efficiency by cleaning the vessel wall through scrapers.
It achieves uniform mixing of high-viscosity polysulfone materials, avoids dead zones in stirring, improves heat transfer efficiency and material crushing efficiency, and ensures the uniformity and integrity of the reaction.
