Therefore, it is necessary to develop and innovate technologies that minimize impacts, without damaging product quality standards. In paint formulations, the dispersion process is of vital importance, which is why this research evaluated the possibility of implementing the technique slurry and pigment concentrate in the traditional way of manufacturing latex-type paints of the premium line (satin and exterior), and partially eliminate the dispersion stage, maintaining the physicochemical characteristics according to Venezuelan COVENIN standards. For this, three types of slurries were used; I: Aqueous dispersion of calcium carbonate (CaCO3), magnesium silicate (MgSiO3) and Kaolin (Al2Si2O5 (OH)4), II: Aqueous dispersion of CaCO3, III: Aqueous dispersion of CaCO3 and Kaolin. Likewise, in the pigment concentrates, two types of aqueous dispersion of titanium dioxide (TiO2) of medium and high dispersibility were used. As a result, there were no significant variations in terms of the quality characteristics of the paints obtained through the process by slurry and pigment concentrate with respect to the traditional manufacturing process. In addition, a reduction of 102 minutes was achieved on the global manufacturing time, since the previous dispersion of the pigments and extenders present in the pigment concentrates and slurries was used, thus eliminating one of the four stages of the manufacturing process of the lines (scattering stage). With the use of slurries and pigment concentrates, it was possible to increase productivity by 31.20 %, becoming an alternative for paint manufacturers, without investing in new equipment. 2022 artículo científico 1657-4583 https://www.redalyc.org/articulo.oa?id=553772634001 https://www.redalyc.org/journal/5537/553772634001/ https://www.redalyc.org/journal/5537/553772634001/html/ https://www.redalyc.org/journal/5537/553772634001/553772634001.epub https://www.redalyc.org/journal/5537/553772634001/movil 10.18273/revuin.v21n2-2022001 en http://www.redalyc.org/revista.oa?id=5537 Revista UIS Ingenierías application/pdf Universidad Industrial de Santander Revista UIS Ingenierías (Colombia) Num.2 Vol.21 |
