现在测定工业碳黑比表面积广泛使用着吸附水溶液中某些活性物质的方法[1]。表面活性物质不能浸入工业碳黑表面的孔隙,按照表面活性物质吸附法测定的比表面积表明聚合物分子能够达到的工业碳黑的外表面积Si。基于吸附隋性气体的BET法能够测定工业碳黑的总表面积So。快速而且准确地测定工业碳黑的外比表
The determination of industrial carbon black surface area is now widely used to adsorb certain active substances in aqueous solutions [1]. The surface active material can not penetrate the pores of the surface of industrial carbon black. The specific surface area as measured by the surface active material adsorption method indicates the external surface area Si of the industrial carbon black which the polymer molecules can reach. The total surface area So of industrial carbon black can be determined based on the BET method of adsorbing inert gases. Fast and accurate determination of industrial carbon black external ratio
