Obtención por filtroprensado de pastas cerámicas a partir de barbotinas nacionales empleando la Planta Piloto de Cerámica de la EPN

Abstract

In this project, the production of industrial ceramic pastes was carried out, from national slips, through the pre-designed filter process, using the EPN ceramic pilot plant. The initial state of the equipment was verified to determine the type of maintenance to be implemented. With the operational equipment, operational tests were started using slips of different densities to define operating parameters. Then we proceeded with the preparation of slips to produce red and white pastes, which were used for the filter-pressing process and subsequent obtaining plastic pastes. Taking into account the scarcity of ceramic pastes in the market and the abundance of clay minerals in the country, the work done seeks to be a contribution to the national artisanal ceramic sector. Regarding the maintenance of the pilot plant, visual inspection and functionality tests were carried out; on the other hand, viscosity and density values of the slips were controlled to produce ceramic pastes. Likewise, test specimens were removed from the filter pastes for further evaluation. With the results obtained, the correct functioning of the equipment is verified, which are in the ability to operate slips ranging densities from 1.5 to 1.8 [g/cm3] without any inconvenience,and plasticity indexes of 17 and 14%, resulting in ceramic pastes suitable for craftsmanship.
