Análise e diagnose dos sistemas de proteção anticorrosivos mais efetivos aplicados às torres de telecomunicações

Abstract

Telecommunication towers are structures used to facilitate the propagation of sound waves over long distances therefore facilitating the signal disclosure without interference. These structures are generally constructed of metals and this choice occurs because of their properties, such as good weldability, high mechanical strength and for simple periodic maintenance. However, metals are subject to the phenomenon of corrosion in their structure and if not controlled can cause great damage. Understanding what is corrosion and how it spreads brings great benefit to determine which anticorrosion protection is most appropriate for each situation and in the case of telecommunications towers the main protections are through the processes of galvanization and industrial paints. By performing visual inspections, it was found favorable points for the appearance of corrosion in the telecommunication tower evaluated at VIVO and with the application of the accelerated corrosion test by immersion it was possible to determine the effectiveness of the use of the protection by standard synthetic enamel in the A-36 steel and thus validate the use of this type of protection
