Organic modified bentonite, vertical antifouling barrier construction method and vertical antifouling barrier
The invention relates to organic modified bentonite, a vertical antifouling barrier construction method and a vertical antifouling barrier. The method is suitable for the field of geotechnical seepage prevention. The technical scheme of the invention is to provide organic modified bentonite, a vertical antifouling barrier construction method and a vertical antifouling barrier. The invention relates to organic modified bentonite which is characterized in that bentonite is modified by adopting a macromolecular hydrophilic organic matter, so that a hydrophilic organic molecular chain is embedded into an interlayer domain of a bentonite bimolecular layer. The preparation method comprises the following steps: crushing and sieving calcium bentonite, and drying; uniformly mixing the dried bentonite with a sodium hexametaphosphate solution, drying, and grinding into mixture powder; and mixing the mixture powder with a high-molecular hydrophilic organic matter solution, drying, and grinding to obtain the organic modified bentonite.
本发明涉及一种有机改性膨润土、垂直防污屏障施工方法及垂直防污屏障。本发明适用于土工防渗领域。本发明的技术方案为提供一种有机改性膨润土、垂直防污屏障施工方法及垂直防污屏障。一种有机改性膨润土，其特征在于：采用高分子亲水性有机物对膨润土进行改性，以将亲水性有机分子链嵌入到膨润土双分子层层间域。取钙基膨润土，碾碎过筛后，烘干；将烘干后的膨润土与六偏磷酸钠溶液混合均匀，烘干后碾碎成混合物粉末；将混合物粉末与高分子亲水性有机物溶液混合，烘干后碾碎，制得有机改性膨润土。
