Diseño de un Sistema de Dispersión Utilizando Agua de Lavado de Resinas en la Fabricación de Pinturas Acuosas

Abstract

This research deals with the design of a dispersion system using resin wash water in the manufacture of aqueous paints in the company Pinturas Condor S.A. in the city of Quito. The method used is the experimental method. The elements used for the analysis are: resin reactor wash water, dispersion paste; and various materials such as: beakers, lacquered containers, test tubes and laboratory equipment. Tests were carried out by replacing 25%, 50% and 100% of the local service water with the washing water of the vinyl acrylic resin reactors, including them in the dispersion phase in the elaboration of the architectural paint brand Vinyl Acrylic Latex. These tests revealed that with the replacement of 25% of water, it was technically feasible and economically feasible, evidenced by the monthly savings in addition to the importance of the environmental contribution generated. On the other hand, and as a result of the calculation performed, it was determined that a centrifugal pump with a power of 2.2 HP is required to transport the resin washing water from the reservoir tank to the vinyl acrylic latex dispersion system. In conclusion, at the end of the present work, it was determined that it is possible to design a dispersion system using water from the washing of aqueous resins to the dispersion process of an architectural paint. For all the tests and results, it is recommended to start the execution and implementation of the project.
