摘要
针对SBS现有生产工艺和设备中存在的问题 ,在单层圆筒形流化床干燥试验装置上 ,采用减重法对SBS生产装置中膨胀干燥机出口处的SBS胶粒进行了干燥动力学的研究。测定了风温、风速、筛板开孔率与干燥速率的关系 ;并从微观结构上分析了不同牌号SBS的干燥特性。得到了适合生产装置操作条件的干燥曲线 ,为优化生产装置 ,提高产量提供了理论依据 。
In accordance with the problems occurred in the existing production process and equipment of styrene butadiene styrene block copolymer (SBS),the drying kinetics for the SBS particle at the outlet of the drying extruder was studied by using weight subtraction method on the single layer cylinder fluidized bed drier.The dependence of the drying rate on the wind temperature,wind speed and number of sieve tray holes was determined; the drying features of SBS products of different grades were analyzed on the basis of their microstructures.A curve of drying suitable to the operational conditions of SBS plant was derived;a theoretical basis as well as th practicable improvement measures was put forward for optimizing the plant and raising the production yield.
