造浆粘土的分析中,目前地质矿产部系统对粘土的性能测定了许多指标,如胶质价、膨胀倍数、吸兰量、阳离子交换容量、化学成份中的硅铝比、碱性系数等。这些性能指标在不同程度上反映了被测粘土的属型。由于粘土矿物成矿组份不同,成矿后环境的差 In the analysis of pulping clay, the current system of the Department of Geology and Minerals has determined a number of indicators for the performance of clay, such as the colloidal price, the expansion ratio, the amount of blue absorbent, the cation exchange capacity, the ratio of silicon to aluminium in the chemical composition, and the basicity coefficient. These performance indicators reflect the type of clay tested to varying degrees. Owing to the difference in mineralization components of clay minerals, the environment after mineralization is poor
