Valoración de la efectividad antiincrustante de recubrimientos aplicados a embarcaciones que operan en la Bahía de Cartagena
Palabras clave:
bioincrustación, recubrimiento antiincrustante, biocida, desempeño general del recubrimientoResumen
En este estudio se desarrolló una metodología para evaluar el desempeño, según la eficiencia antiincrustante y anticorrosiva, de seis sistemas antifouling comerciales en las plantas industriales de Mamonal y Bocagrande en la Bahía de Cartagena. El desempeño general de los recubrimientos fue determinado mediante la calificación de la resistencia al biofouling y la integridad del antifouling y de la película anticorrosiva. Adicionalmente se realizó un seguimiento de los parámetros microbiológicos y fisicoquímicos del medio marino en el área de exposición, según los cuales las dos zonas de estudio presentaron condiciones favorables para el desarrollo de los organismos con elevados porcentajes de cobertura de fouling sobre cupones control. En la Planta de Mamonal, los sistemas mostraron una mejor eficiencia antiincrustante respecto a la de Bocagrande. De acuerdo con el tipo de recubrimiento, el autopulimentable presentó un mejor desempeño frente a recubrimientos tipo matriz soluble e insoluble.
