摘    要:
利用数字黏度测量仪对生物质复合材料的浆料阶流变特性进行研究,采用SEM分析浆料中纤维空间结构,最后研究了管道输送料的温度。实验结果表明:浆料中纤维搭接呈网状结构,其黏度随时间先增大后减小,最终趋于稳定。剪切速率和剪切应力之间能够利用卡森模型进行良好的拟合。随浆料温度升高,浆料黏度减小;在温度介于55~85 ℃的,充分搅拌900 s后,浆料黏度较小且稳定,最适合管道输料。

关 键 词:生物质复合材料  浆料  流变特性  纤维空间结构

Abstract:
A digital rotational viscometer was used to study the rheological properties of the slurry of biomass materials and then the spatial structure of the fiber in the slurry was analyzed by SEM.And the temperature of pipeline in transportation was studied.The results suggested that fibers in the slurry had the network structure.Its viscosity raised first and fell down afterwards till a final steady state with stirring time increase.The relationship between shear rate and shear stress fitted Casson Model.With the slurry temperature increasing,the viscosity decreased.In 55-85 ℃,the slurry after 900 seconds' fully mixing was the most suitable for pipeline transportation.
Keywords:biomass materials  slurry  rheological properties  spatial structure of fibers
