ATMOSPHERIC CORROSION AND DEGRADATION OF CONSTRUCTION MATERIALS FOR SOLAR COLLECTORS
Available information on the corrosion behaviour and corrosion rate of different metals under a number of environmental conditions has been described. Materials covered are : carbon steel, weathering steels, stainless steels, zinc, aliuminum and copper. An explanatory approach - similar to the one of Mattsson - which is based on simple thermodynamic fundamentals, may provide a comprehensive general image of the influence of different atmospheric components such as CO-2, SO-2, etc. The plastics that have been discussed in this article (as components on solar installations) mainly include polymethylmethacrylate, polycarbonate, glass fibre reinforced polyester, polyvinylfluoride, fluorinated ethylene - propylene copolymer, polyethylene terephthalate and various sealants and foamed plastics. The aging behaviour of most of these plastics has been widely studied for normal outdoor exposure and in artificial weathering devices, and is described in this paper. Very little information is available, however, regarding their short-term performance under actual service conditions in solar energy installations; nearly none has been reported on their long-term durability.
