膨润土是一种重要的无机化工产品,具有广泛的用途。通过改性可以使其用途更加广泛。本文介绍了活化改性、有机改性、无机改性、无机/有机复合改性以及钠化改性等改性膨润土的研究和开发进展,指出了其今后的发展前景。 Bentonite is an important inorganic chemical product with a wide range of uses. Through the modification can make its use more widely. In this paper, the progress of research and development on modified bentonite, such as activation modification, organic modification, inorganic modification, inorganic / organic modification and sodium modification, are introduced. The future development prospects are also pointed out.
