Análise do tratamento anticorrosivo através da aplicação de pintura na base de uma torre eólica no estado do Piauí: um estudo de caso.

Abstract

The wind industry plays a vital role in sustainable electricity generation. However, weather conditions and constant exposure to aggressive environments can compromise the integrity of these structures, highlighting the strong need for oxidation resistance in wind turbine towers. The study covered technical aspects, provides a comprehensive and detailed view of the distribution treatment, its short and medium term results. This work presents, in the form of a case study, the maintenance carried out at the base of a wind tower in Piauí, proposing an analysis of the initial and final state of the base and documenting the process of its restoration. This analysis not only evaluates the effectiveness of the treatment methods applied to the base of the wind turbine, but also indicates methodologies and painting schemes for the entire wind tower, covering the procedures adopted to protect metal structures exposed to atmospheric corrosion. The results after 10 months of surface treatment with mechanical tools at level St3 and application of a paint scheme with two products (Jotamastic 90 and HardTop XP) highlighted the need to change to surface treatment by abrasive blasting at level Sa3 and application of paint scheme with three products (Barrier Smart Pack, Penguard Universal, HardTop XP).
