Abstract
This paper reports the results of a research work whose main objective is related to the development of a technical solution that takes into account the relationship between the surface abrasion wear resistance and brightness of glazed ceramic tile products. Thus, glazes formulated from a glass-ceramic composition belonging to the LZSA system reinforced with crystalline particles of zircon were prepared and characterized with respect to their scratching and surface abrasion wear resistances and brightness. In this context, a bright (71.2 UB) porcelainized stoneware ceramic tile with high scratching resistance (9 Mohs), high surface abrasion wear resistance (PEI 5), and good staining resistance (Class 4) was obtained.
Highlights
In the last year it has been observed, taking into account the globalization, some changes in the world economic scenery which have impelled the companies, including those of ceramic tiles, to look for the technological modernization and the competition as a manner to improve their positions as players
This paper reports results regarding to the development of a technical solution that takes into account the relationship between the abrasion wear resistance and the brightness to obtain ceramic products with optimized properties and with high performance for application as floor tile
The influence of reinforcing crystalline particles on the scratching and the surface abrasion wear resistances of the prepared glazes from the LZSA glass ceramic had not been evaluated yet. These compositions constitute the main interesting focus of this work since the goal is to obtain glazed ceramic tiles matching the high brightness of the glazed layer on the porcelainized stoneware tile surface and the good abrasion wear, mechanical and chemical resistances of the prepared mixtures according to Montedo’s previous work [15]
Summary
In the last year it has been observed, taking into account the globalization, some changes in the world economic scenery which have impelled the companies, including those of ceramic tiles, to look for the technological modernization and the competition as a manner to improve their positions as players. Much has been invested during the last years with respect to automation technology and optimization of the productive processes as, for instance, wet milling, fast firing and drying in roller kilns and roller driers, respectively, automation and integration of the productive steps by means of control software, and so forth [1] These changes are more and more available to all producers of ceramic tiles, which, having financial support, have had access to the most new world technologies that is, the difference between the bigger producers and the smaller ones, technologically, has been progressively decreasing. In Brazil the changes in the consumer’s behavior such as their demand and the creation of the consumer’s code have conducted the customer to demand technically differentiated products with esthetically and strong appeal to the quality In this way, ceramic producers have been pressed to increase the value of their products in order to attract the customer’s preference since more and more similar products in price and quality are available in the market. The overall market traditionally has demonstrated greater preference for products with high
