【摘要】 以四川新康石棉矿中风化林滤成因海泡石为研究对象,对其化学成分、应用性能进行了研究。结果表明,四川新康海泡石化学成分与我国热液成因纤维状海泡石成分基本一致,与沉积成因土状海泡石成分差别较大,属于富镁海泡石变种。与其他成因海泡石对比,它具有较好的热稳定性、较大的离子交换容量和比表面积,是一种优良的过滤吸附矿物材料。更多还原

【Abstract】 Chemical compositions and application properties of sepiolite formed by weathering-leaching geological action and occurred in asbestos mine in Xinkang, Sichuan were studied in the paper. The result showed that its chemical compositions were similar to that of fibrous-shaped sepiolite formed by hydrothermal action, but it had a big difference from earth-shaped sepiolite formed by sendimentary action in the chemical compositions. The sepiolite from Xinkang Sichuan belongs to rich magnesian sepiolite variant. Compared with the others genesis sepiolites, it has better heat stability, bigger cation-exchange capacity and specifical surface areas. It is a kind of good quality absorptive and filtrating mineralogical materials.更多还原
