Stabilization of the Dispersed System of Halloysite Nanotubes for Silicate Constructional Material

The stabilization of the dispersed system of halloysite nanotubes (HN) obtained by ultrasonic treatment (UST) in the aqueous medium of the stabilizers of sodium polynaphthalene methylene sulfonate stabilizers (S-3) and a synthetic compound based on polycarboxylate ether (MG) is considered. The morph...
