1. Numerical simulations of ceramic firing in catenary kilns
Abstract Kiln geometries were developed to reach homogeneous temperatures above 900 °C, during the firing process, aiming to improve the production process of the ceramists from Vale do Jequitinhonha (MG/Brazil). Techniques of reactive flow numerical solution using the software Ansys CFX have been used to foresee the behavior of the firings. Two types of ca

4. Estudo do desempenho do processo de microfiltração tangencial com membranas cerâmicas aplicado à retenção de bactérias e redução de sólidos suspensos de uma bebida à base de açaí / Performance study of the crossflow microfiltration process with ceramic membranes applied to the bacteria retention and suspended solids reduction of the beverage based on açai
In this doctoral research, the crossflow microfiltration process utilizing ceramic membranes was investigated aiming at the bacteria retention (Escherichia coli) and reduction of suspended solids of beverage based on açai (Euterpe oleracea Mart.). The selected commercial membranes of alfa-alumina (AL IND.2O IND.3) had nominal pore sizes of 0.8 and 1.2 müm

5. Influência da gipsita no surgimento de eflorescência em telhas cerâmicas
The red ceramic industry is recognized as of major importance in Piauí State. The State capital, Teresina, is the greatest producer of this material ( production about 18 million peaces), which is used mainly for masonry sealing blocks. One of the most frequent problems in this kind of products is the efflorescence. This work has the main objective of study

9. Avaliação de engobes no aparecimento da mancha d´ água em revestimentos cerâmicos / Engobes Evaluation in the Water Stains Ocurrence in Ceramic Coatings
The water stain phenomenon is a typical problem in the Brazilian industry of ceramic coatings, characterized by presenting a tonality variation of the ceramic piece enamel surface, when in contact with water. The engobe is used, among other reasons, to milden the water stain phenomenon. This work aimed to study the influence of the different thicknesses of t

12. Influência do lodo de ETE na massa para fabricação de cerâmica vermelha
The WTP produce many kinds of residue on your treatment stages, but the sludge is the more problematic from the final disposition point view. The actual rate of residue production deriving from technological evolution and the crescent population needs prevents the subtle equilibrium generation between consumption and recycling/reuse, creating problems of pol
