摘要
为了改善膨润土的性能,扩大其使用范围,综述了膨润土的结构和针对这种独特的片层结构进行的改性原理及方法,以及制备得到钠化改性膨润土、活化膨润土、有机改性膨润土和纳米复合膨润土等不同类型的改性膨润土,并分析了膨润土改性后在环境保护、载体等领域的应用与前景。改性膨润土大大提高了膨润土的性能与品质,改变了中国膨润土资源品质低、应用受到限制的局面,有助于充分利用好中国丰富的膨润土资源,提高其附加价值,创造更大的经济效益。
Aiming at improving the properties of bentonite and expanding its use, the structure of bentonite and the the- ory and methods of modification for the unique lamellar layers of bentonite were introduced as well as the modified benton- ites, such as sodium bentonite, activated bentonite, organically modified bentonite, and bentonite nanocomposite were pre- pared. Applications and prospects of those modified bentonites used in environmental protection and carrier materials and other fields were analyzed. Properties and quality of bentonites were improved greatly by modification, thus changing the situation of low quality and limited application of bentonite, helping to fully use the rich bentonite resources in China, increasing its added value, and creating greater economic benefits.
