低熔点熔体弹珠的造粒过程及其性能OACHSSCDCSTPCD

The purpose of this study is to address issues such as tailing and breakage in the sulfur granulation process,in order to enhance product quality and operational continuity.Expanding on the concept of liquid marbles to molten marbles,this paper introduces the fabrication of sulfur molten marbles using superhydrophobic surfaces.Polytetrafluoroethylene(PTFE)was employed as the coating material for the particles,successfully increasing the yield from 84％to 97％during the sulfur granulation process,while simultaneously reducing phenomena like tailing and breakage.The improved sulfur particle product retained a certain strength and enhanced its visual appearance.Additionally,the concept of sulfur marbles can be extended to other materials with similar high-temperature phase transitions,enabling the creation of functional molten marbles with properties such as sustained release,moisture retention,and phase-change heat transfer.The research findings demonstrate that leveraging the characteristics of molten marbles can effectively enhance balling effect in the sulfur granulation process,while also improving mass transfer effects.This provides viable strategies for innovation and optimization in industrial technologies for similar granulation and absorption processes.
