Abstract
MOLINA-MACIAS, Anngie K. and PENUELA, Gustavo A.. Effect of the water quality of the benefit process in the rheology of the ceramic kaolin suspensions. Ing. compet. [online]. 2019, vol.21, n.1, pp.117-126. ISSN 0123-3033. https://doi.org/10.25100/iyc.v21i1.7671.
In the obtaining process of the kaolin by wet way, the influence that the quality of the water in the rheological properties of the suspensions of ceramic kaolin was evaluated, for which benefit tests of kaolin were carried out, using the same raw material and water of different sources and quality. The rheological properties of the kaolin suspensions were measured in terms of electrolyte demand -DE-, thickening, the Methylene Blue Index -IAM- and the rate of deformation. The parameters of water quality evaluated were pH, conductivity, acidity, alkalinity, total hardness and free chlorine. It was found that when alkalinity, the acidity and conductivity of the water used to obtain kaolin increases, also does the DE of the suspensions, however, despite observing a different behavior between materials obtained from washing with water with few ions content and materials obtained from washing with water with some more ions content, no specific relationship was found for thickening.
