Disclosed are methods of preparing drilling fluid compositions containing treated calcium bentonite. One such method includes mixing calcium bentonite with an aqueous mixture containing soda ash, followed by adding starch to form the treated bentonite mixture that is used to prepare a drilling fluid composition. Another method includes mixing the calcium bentonite with an aqueous mixture containing soda ash and magnesium oxide, followed by adding starch to form the treated bentonite mixture that is used to prepare a drilling fluid composition.

Method for the production of granular materials designed to be used as aggregates and fillers in a mix containing a binder for the manufacture of articles in slab or block form. The method comprises a step of melting a mixture of selected minerals having a specific chemical composition, a step of casting the molten material, a step of cooling the cast material until a predetermined temperature is reached and a step of crushing and/or grinding the cooled material to obtain granular materials having a selected particle size and suitable for use as aggregates or fillers in the mix for the manufacture of articles in slab or block form. Moreover, the method comprises, upstream of the melting step, a step for recovery and collection of the manufacturing waste of other previously manufactured articles. The manufacturing waste is designed to compose at least partially the mixture of selected minerals. The invention also relates to a method for manufacturing articles in slab or block form from a mix containing the aggregates and the fillers and a binder.

Electrically conductive thermoplastic polymer composites of particulate thermoplastic polyester polymers, electrically conductive components (carbon nanofibers, graphene nanoplatelets, and/or conductive metal nanoparticulates), processing aids such as plasticizers, thermal stabilizers, etc., as well as nanoscopic particulate fillers such as nanoscopic titanium dioxide, etc., the electrically conductive components being distributed substantially uniformly in the composite to form an electrically conductive network. Also, methods for preparing thermoplastic polymer composites, a system for collecting extruded filaments prepared from thermoplastic polymer composites as a coil of filament, as well as method for tempering articles formed from thermoplastic polymer composites to increase the degree of crystallinity of the thermoplastic polymers and thus their mechanical strength properties.
