RESUMO:

Porcelain stoneware tiles stood out as one of the ceramics of major importance, since its development provided products of excellent technical and aesthetic quality. To improve its characteristics, the porcelain tile is subjected to a polishing process, which, in addition to being complex and important, is quite expensive, with a high consumption of raw materials and natural resources. Beyond the technological performance, there is also a trend towards the use of sustainable coatings through the reuse of raw materials. In the case of polished porcelain tiles, obtaining the glossiness gain curve in the polishing process is necessary both to guide the improvement of the polishing operation and to evaluate the reuse of residues by the incorporation of material in the mass formulation. This paper aims at both purposes. In order to achieve this, glossiness gain curves will be obtained with and without the addition of red ceramic waste (Chamotte), and also considering the omission of some abrasive granulometry in the polishing process. A metallographic polisher will be used to reproduce the industrial polishing process. For all tests, the polishing sequence will normally follow abrasive #36 to #400, followed by three different polishing strategies up to # 800 abrasive. After the abrasives have passed, the evaluation of the early advance of the granulometry will be done by monitoring the gloss and roughness measurement of the porcelain tiles.
