Análisis de falla de los bujes del tornillo de una extrusora utilizada para procesar pintura en polvo

Abstract: RESUMEN Este artículo tiene como objetivo presentar el análisis de falla de los bujes del tornillo de una extrusora utilizada para la fabricación de pinturas en polvo. Para esto se seleccionaron dos bujes, uno de la zona de transición y otro de la zona de dosificación. Se realizaron análisis de composición química y microestructural, ensayos de dureza y un análisis detallado de las superficies falladas mediante examen visual y microscopía electrónica de barrido. Los resultados mostraron que los bujes fueron fa… Show more

“…As a result, the thermosetting coatings are stable and do not react to reheating, which is why, unlike thermoplastic coatings, they do not soften. The advantages of the powder method are that it does not affect the environment (the powder coated coatings do not emit the organic compounds responsible for ozone) and do not increase the economic costs associated with the petroleum solvents used in traditional liquid coatings (Pardo, Aristizabal, 2017).…”
