Influence of deflocculant addition on rheological properties of the slurries based on bauxite
Abstract
Purpose: The objective of the paper is to present the properties of ceramic slurries based on bauxite with different deflocculants. Design/methodology/approach: The slurries were performed in air conditioned laboratory by a mechanical mixer. The rotation speed of the mixer was 300 RPM and the mixing time was 3 hours. To characterize the bauxite structure, SEM Hitachi SU-70 was used. Furthermore, chemical composition by XRF method was executed. Grain size of bauxite was measured by Horiba laser diffractometer. The rheological properties were studied at Rheometer MCR 102 (Anton Paar) by coaxialcylinders method. Findings: Investigated ceramic slurries based on bauxite show stable rheological properties in time. It could be concluded that ceramic slurries with obtained properties might be used in ceramic proppant manufacturing in the future. Research limitations/implications: The main restriction in rheological properties of ceramic slurries modification is to use aqueous binders and deflocculant solutions. In Polish manufacturing water as a main binder (max. 5 wt. %) and of deflocculant (0.25 wt. % with respect to the powder) additives are required. This kind of limitation has an influence on the part of the solid phase concentration of ceramic slurries. For that reason ceramic slurries with 45 wt. % solid content are investigated. Practical implications: Presented ceramic slurries could be used in ceramic proppant fabrication by spray drying process in the future. Originality/value: This is one of the first application of bauxite to produce ceramic proppants using spray dryer in Poland. Ceramic proppants could be used as additives to fracturing liquid in shale gas extraction process.
