摘要
本文通过X射线衍射分析、红外线光谱、电子显微镜、阳离子交换量测定及造浆率测定等方法,研究湖北钟祥累托石热处理与造浆率的关系。原生带累托石150℃处理后就不能成浆,氧化带累托石500℃处理后才造不出浆来。从两类累托石内部结构变形、伴生矿物及酸碱度不同,初步阐明两类累托石耐热性差异的原因。
The relationship between heat treatment and the mud-making rate of rectorite in Zhongxiang, Hubei has been established in terms of X-ray diffraction (XRD) and infrared absorption spectral analyses(IR), electron microscopy (TEM,SEM), cation exchange capacity(CEC)and mud-making rate in this paper. In case rectorite from the primary zone is treated at 150℃, no mud fluid is expected, and in case that from the oxydation zone is treated at 500℃ no mud fluid is expected. From the differences in structural deformation, associated mineral species and alkalinity-acidity (pH) for the two types of rectorite, a reasonable explanation is presented of the difference in heat-resistance for the two types of rectorite.
