FURNAS Electricity Pylon – Serra do Mar, Brazil
FURNAS Electricity Pylon – Serra do Mar, Brazil
ZINGA was applied on a highly corroded high tension power pylon of the electricity company FURNAS, in February 1999. The surface was manually prepared by metal brush, sand-paper and by degreasing with turpentine. Zingasolv was used to clean the brushes and to dilute the ZINGA when necessary. Considering the aggressive area, 2 layers were applied with a DFT of 40 µm with an interval of 2 hours. The total surface was 332.31 m².5 Kg ZINGA pails were used covering 11 m². ZINGA was applied in an ambient condition of high humidity. Adhesion tests gave a very positive result.
System:
Surface preparation:
Manual steel brush, sand-paper, degreasing ZINGA 2 x 40 µm DFT
Application of ZINGA on tower 205 of LT 345 kV Ibiuna – Tijuco Preto circ. 1 & 2
The present report relates to the assignment to the Departamento de Produção São Paulo (DRL.O) through the Division of Electromechanical Maintenance (DMES.O) of an experimental application of ZINGA on a highly corroded structure.
A structure with easy access was chosen in an industrial environment with a high degree of pollution: the tower 205 of LT Ibiuna – Tijuco Preto 1&2 in the region of Serra do Mar, near to the Chemical Plant Elclor, in Rio Grande da Serra.
COMMENTS
ZINGA is a system with easy application not requiring a rigorous cleaning, for which humid ambience doesn’t interfere in the accomplishment. One year after the application the project (Tower 205) remains in a perfection condition. Only 2 highly corroded pieces that intentionally weren’t submitted to a surface preparation, are showing a few spots of oxidation: this was to verify in how far the cleaning would influence the behaviour of the product.
20 years later, on 9 August 2019 ZINGA BRAZIL made a visual inspection on an unusual sunny day.
The location is close to a village (Ribeirão Grande da Serra – SP, east of the City of São Paulo) on top of the Serra do Mar (Sea Mountains), a very rainy and foggy place.
It is close to the chemical plant of ELCHLOR (Chlorine manufacturer). ZINGA is still in pristine condition and does not need to be reloaded.
25 years later, in March 2024, ZINGA BRAZIL made a new visual inspection.
It was confirmed that the quality of the ZINGA film remains in excellent conditions, even after this long period in several conditions of humidity and temperature, ZINGA still and effectively protects the substrate against corrosion.
