| dc.description.abstract | The use of organic solvents as raw material for diverse coatings applied in the prevention and control of corrosion in several industries and the high quantities of expanded polystyrene to be disposed after being used have generated a great controversy worldwide, as they have harmful effects on human health and on the environment.Objective.This study proposes the use of recycled expanded polystyrene, with limonene as a solvent, for its use as anti-corrosive. Materials and methods. Different formulas were developed, after being obtained corresponding to different quantities of recycled expanded polystyrene, limonene, titanium dioxide and zinc oxide, using a constant quantity of cobalt octoate as an additive. After preparing each formulation the anti-corrosive potential of the coating on carbon iron metal plates was assessed, by means of a salt spray chamber test.Result.By comparing the coating obtained with a commercial coating, in terms of efficiency and capacity to prevent and control corrosion, the conclusion is that the coating developed in this project only had a 10 % of its surface corroded, while the coating painted with the commercial coating had 50 % of its surface corroded. Conclusion.Good results in the anti-corrosion properties of the different coating formulations were obtained, thus making possible their use as anti-corrosive coating. | es_ES |
| dc.description.resumen | El uso de solventes orgánicos como materia prima en la fabricación de diversos recubrimientos aplicados para la prevención y control de la corrosión en las diferentes industrias, y las grandes cantidades de poliestireno expandido que se desechan después de ser utilizadas han generado gran controversia al nivel mundial debido a los efectos nocivos que tienen sobre la salud humana y el medio ambiente. Objetivo. Por tanto, se plantea el uso de poliestireno expandido reciclado utilizando limoneno como solvente para su uso como anticorrosivo. Materiales y métodos. Se desarrollaron diferentes formulaciones que se obtuvieron en función de diferentes cantidades de poliestireno expandido reciclado, limoneno, dióxido de titanio y óxido de zinc, utilizando una cantidad constante de octoato de cobalto como aditivo. Al término de la preparación de cada formulación se procedió a evaluar el potencial anticorrosivo del recubrimiento sobre placas metálicas de acero al carbono mediante un ensayo de cámara de niebla salina. Resultado. Al comparar el recubrimiento obtenido con un recubrimiento comercial en cuanto a su eficiencia y capacidad para la prevención y control de la corrosión, se pudo concluir que el recubrimiento desarrollado en este proyecto solo presentó un 10 % de superficie corroída, frente al 50 % de superficie corroída de la probeta pintada con el recubrimiento comercial. Conclusión. Se obtuvieron buenos resultados en las propiedades anticorrosivas de las distintas formulaciones del recubrimiento haciendo posible su uso como recubrimiento anticorrosivo. | |
