Uses of high-quality attapulgite clay
Raw material characteristics: The attapulgite content is greater than 85%, and the main impurities are micron-sized clastic quartz, feldspar, and a small amount of autogenous opal and dolomite. Processed products: series of attapulgite nanomaterials and derived materials.
Technical key: Attapulgite parallel crystals present a crystal beam structure, and the key is to promote crystal beam depolymerization.
Technical route: wet depolymerization, dispersion, purification, modification, nanocompositing.
Processing technology: pulping-steam explosion-(solvent heat treatment, acid treatment)-swirl separation impurity removal-recovery-modification.
