Item Efeitos da temperatura no comportamento mecânico de matérias-primas utilizadas na produção de cerâmica de revestimento em indústria do Cabo de Santo Agostinho – PE(2021-01-30) Silva, Renata Arcelino da; Diniz, Verônica Cristhina de Souza; http://lattes.cnpq.br/9239037374332331; http://lattes.cnpq.br/4639841941851252The properties of ceramic tiles are dependent on their chemical composition and on the microstructure developed, mainly during the heat treatment to which they are developed. In this study, aimed to evaluate the influence of temperature on the mechanical behavior of ceramic raw materials of different compositions used in production of ceramic tiles, allowing their analysis and processing in a simple, controlled and standard. Six raw materials donated by a ceramic coating industry from Cabo de Santo Agostinho - Pernambuco were used. Samples of raw material were compacted by uniaxial pressing, then subjected to controlled sintering at 1000, 1100 and 1200 ° C for 1h, with a heating rate of 5ºC / min. Then, properties were evaluated per of linear shrinkage, water absorption, apparent porosity and flexural strength. The samples MP5 showed a good mechanical performance in relation to temperature variation, showed maximum strength, 45.27 MPa at 1100ºC, associated with low porosity (2.34% at 1100ºC) and the minimum concentration of internal cracks resulting from the low retraction of the part (6.34% at 1100ºC). Therefore, the raw materials presented physical properties for use in various applications in ceramic tile.Item Caracterização de matérias-primas cerâmicas utilizadas na produção de placas de revestimento em indústria do Cabo de Santo Agostinho(2019-12-10) Silva, Renata Arcelino da; Diniz, Verônica Cristhina de Souza; http://lattes.cnpq.br/9239037374332331; http://lattes.cnpq.br/4639841941851252Properties of ceramic products are related to initial characteristics of raw materials, so it is important to study them to obtain a quality product. In this study, aimed to evaluate clay composition and study physical-mechanical behavior of different raw materials used in production of ceramic tiles, allowing their analysis and processing in a simple, controlled and standard. Six unidentified raw materials donated by a ceramic coating industry from Cabo de Santo Agostinho were used. The samples were benefited and characterized per X-ray diffraction (XRD), Energy-dispersive X-ray spectroscopy (EDX) and sedimentary particle size. After, raw materials were uniaxial pressing and subjected to controlled burning at 1000 ºC/ 1h with rate of 5ºC / min. Then, properties were evaluated per of linear shrinkage, water absorption, apparent porosity and flexural strength. The samples presented crystalline phases of kaolinite, quartz, mica and smectite, besides of alkaline oxides. The mechanical properties of samples showed the highest plasticity index (18%) and maximum strength went MP1 and MP6, 18% and 20.45 MPa, respectively. Thus, the raw materials presented physical properties for use in various applications in ceramic tile, such as ceramic.
