膨润土的改性及其应用 摘要：膨润土是以蒙脱石为主的含水粘土矿，具有膨润性、粘结性、吸附性、催化性、触变性、悬浮性以及阳离子交换性等特性，因从广泛用于各个工业领域。但由于膨润土的多重性质，使其在实际应用中受到多重限制，且不能达到很好的效果。所以，为了提高膨润土的使用价值及其效率，应该对膨润土进行改性，以提高其价值。膨润土具有很高的科研价值，对各种领域都有极其重要的作用。国内外已在工农业生产24领域100多个部门中应用，有300多个产品,因而人们称之为“万能土”。我国膨润土的储量世界第一位，种类齐全，分布广，遍布26个省市，产量和出口均居世界前列。因此，膨润土的发展和研究对我国具有极其重要的意义。 关键词：膨润土；改性；意义；应用；前景

Abstract：The bentonite is mainly to montmorillonite aqueous clay mineral, with swelling, adhesion, adsorption, catalysis, thixotropy, suspension and cation exchange properties, widely used in various industrial fields from. But as a result of bentonite multiple nature of the constraints, so that in the practical application subject to multiple constraints, and can achieve good results. Therefore, in order to improve bentonite use value and efficiency, to bentonite should be modified, to enhance its value. Bentonite has very high research value, to the various fields have extremely important role. At home and abroad has been in production of industry and agriculture24areas more than 100 departments in the application, there are more than 300products, so people called the "universal soil". China's Bentonite reserves are the world the first, variety complete, widely distributed, in 26 provinces and cities, and export crop all occupy world front row. Therefore, bentonite on the development and research to our country has very important significance.
