1986年12月地矿部湖南省地矿局一行五人赴西班牙进行为期二周的海泡石专题考察。海泡石是一种具链层状结构的富镁粘土矿物,由于它具有抗盐、耐高温的热稳定性,流变性好,以及吸附性强等特性,因此,已广泛应用于工农业和环境保护等各个领域,如石油井和地热井勘探;化工、油脂工业中做吸附剂、摧化剂载体,橡胶填料以及动物饲料等,约有50多种工业用途。但由于海泡石资源在全世界较少,只有少数国家拥有,而西班牙海泡石资源丰富,居世界首位,其产量和质量,几乎垄断了全世界。而
In December 1986, the Department of Geology and Mineral Resources Hunan Provincial Bureau of Geology and Mineral Resources went to Spain for a two-week special study on sepiolite. Sepiolite is a kind of magnesia-rich clay mineral with chain-like structure. It has been widely used in agriculture, industry and agriculture due to its characteristics of salt resistance, thermal stability at high temperature, good rheological property and strong adsorption. Environmental protection and other fields, such as oil wells and geothermal wells exploration; chemical industry, oil industry as adsorbents, catalyst carriers, rubber fillers and animal feed, about 50 kinds of industrial uses. However, sepiolite resources in the world is less, only a few countries have, and Spain is rich in sepiolite resources, ranking first in the world, its production and quality, almost monopolize the world. and
