Efeito do ambiente marítimo na corrosão de contentores de lixo na zona da Costa do Sol : análise e proposta de medidas de proteção

Abstract

This work analyzes the factors that lead to the corrosion of metal containers in the Costa do Sol area and proposes protective measures to increase their useful life. Firstly, the types of existing garbage containers are studied, their advantages and disadvantages, as well as their importance in society. Secondly, the manufacturing process of containers on the market is studied, and the type of material from which the containers are made is also studied, in order to determine whether or not they are resistant to corrosion in the environment in which they are allocated. The coastal environment of the Costa do Sol is studied in order to know the relative humidity of the region, predominant temperature, wind scale in the region, acidity of the environment (from the PH of the region to the type of sediment particles present in the atmosphere ) in order to analyze whether they cause the acceleration of the corrosive process in that region, also study where the containers are placed on the ground (since the ground also contributes to corrosion), on the tarmac or paved road or suspended, as is the case with cylindrical containers small metals with a diameter of 700 mm and lengths of 1000 mm. The type of corrosion frequently experienced by garbage containers located in coastal environments is studied in order to find the best methods of protecting these effects. The types of coatings that metal containers can receive to avoid the oxidation of the metal, with special attention to painting and the types of galvanizing processes and the reasons that lead to its removal from the structure. After carrying out the study mentioned above, the factors that most influence the increase in the rate of corrosion are identified and measures are subsequently proposed to protect the containers.
