COMPARISON BETWEEN THE GLOSS VALUES OBTAINED IN DIMENSION STONE SUBMITTED TO THE POLISHING PROCESS WITH DIFFERENT RESINS

Comparison between the gloss values obtained in dimension stones submitted to the polishing process with different resins

Abstract

ABSTRACT – The brightness of a dimension stone after polishing is the main characteristic analyzed in relation to the quality of production, a factor that can be decisive during its commercialization. Empirically, it is said that resin is an influential part of the quality of the gloss after polishing the stone. For this purpose, this article demonstrates, through an experiment carried out in an industry, by polishing slabs of a quartzolytic rock,  a difference in the measured brightness in surfaces that received different Epoxy Systems, in order to demonstrate what the characteristics of these systems that caused the direct influence on the brightness result. The results showed that there is an intimate relationship between the adopted system and the measured brightness results. In this study, the best system was the IV, presenting values much higher than others. Aspects related to the price of the inputs and production time must be considered when choosing which system should be adopted. This research is an important step towards a reduction in the empiricism that permeates the dimension stones sector and aims at better control of the production process and an increase in the quality of Brazilian dimension stones.
