Evaluación del desempeño de recubrimientos poliméricos utilizados en el control de corrosión externa para equipos de proceso en campo la Cira corregimiento el centro - Barrancabermeja
Para la evaluación del desempeño de los recubrimientos orgánicos de imprimante epóxico, con acabados/ poliuretano, polisiloxano, poliaspártico y uretano A.R aplicados sobre un acero de medio carbono, se sometieron a un ambiente simulado salino, cámara de lluvia ácida y U.V, para determinar por inspe...

Desprendimiento Catódico
Espectroscopía De Impedancia Electroquímica
Recubrimientos Orgánicos.
For the evaluation of the performance of organic coatings epoxy primer
enamels / polyurethane
polysiloxane
polyaspartic and urethane AR applied on a medium carbon steel
they underwent a saline simulated environment
acid rain and camera U.V. to To determine by visual inspection in fissured systems blistering and advancing the process of corrosion and not fissured systems the variation in brightness and color. At this stage
there was an installation of a monitoring station in the field Cira of Barrancabermeja
there coating systems were exposed without damage with bare systems to natural conditions. Spectroscopy technique electrochemical impedance systems already exposed in saline and applied camera acid
which demonstrated a proper purely capacitive behavior of coatings under the action protecting barrier. Finally cathodic disbonding test was performed to study systems without exposure
indicating the ability of the epoxy primer 82% solids to resist delamination around the cracks. Of the four systems evaluated
the coating consisting of an epoxy primer 82% solids and an enamel polyurethane A.R showed high resistance to the passage of pollutants
lower absorption of electrolyte greater retention of brightness
whiteness
lower yellowness index and lower corrosion blistering density and therefore this system has the ability to withstand saline environments
acids and constant ultraviolet radiation without loss of resistance or surface optical characteristics
