DURABILITY OF ANTICORROSIVE PROTECTION COATINGS FOR ELECTRO-ENERGETIC EQUIPMENT

Abstract

Determining the working life of the anticorrosive protection layers is of great importance for electro-energetic installations. In order to assess the durability of the paint layers have been achieved films of 100 ÷ 120µm from six different commercial types of paint. After polymerization/drying, the dielectric characterization of the obtained films has been achieved by dielectric spectroscopy - both before and after their exposure to controlled doses of UV radiation. The experimental results have been revealed that the polymer matrix of the painting materials, over a critical dose of UV radiation (specific commercial sort), suffers a complex process of aging after which the anticorrosive insulation capacity decreases.
