| Resumo: | Porcelain stoneware tiles have major importance among the ceramic floor
tiles, since their development provided products of excellent technical and aesthetic
quality. To improve its characteristics, the porcelain tile is subjected to a polishing
process, which besides complexity and importance, has a high consumption of
water, energy and abrasives. Beyond the technological performance, there is also
a trend towards the use of sustainable coatings through the reuse of industrial
wastes. 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 validate the incorporation of industrial wastes in the mass
formulation. This Master Thesis aims at both purposes. In order to achieve this,
glossiness gain curves were obtained with and without the addition of red ceramic
waste (Chamotte, or also grog), while considering the variation of the industrial
polishing route. For all tests, the polishing sequence will normally follow abrasive
#36 to #400, followed by three different polishing routes up to # 800 abrasive. After
abrasives were passed, the influence of the route variation was evaluated by
measuring the glossiness and surface roughness of the samples. The results
demonstrated the applicability of the chamotte porcelain tile that obtained final
glossiness responses on average 16.8% higher than the standard porcelain. It was
possible to verify that, within the parameters used, there was no significant influence
of the polishing route variation. As consequence, it is possible to omit abrasive #600
without significant aesthetic loss. |
