ABSTRACT

The deterioration of materials due to the effect of atmospheric pollution generates a cost to society because the maintenance and replacement of degraded materials. Galvanised steel is used in electrical industry to build electrical transmission towers (ETT). The objective of the study was to estimate the annual maintenance cost of galvanised steel used in the construction of ETT. The maintenance cost for galvanised steel was estimated considering the cost of the material surface area and the difference between the maintenance interval of clean and contaminated areas. Maps of intervals and maintenance costs were obtained for galvanised steel (85 and 100 µm), which are the thicknesses regulated in Mexico for ETT. In addition, an ArcGis geographic information system was used for a spatial representation of data from the anthropogenic environment. The mapping of areas at risk of corrosion shows that in the northwest zone, ETT presents the highest maintenance costs for the year 2019. For galvanised steel thicknesses of 85 and 100 µm, there are annual costs of, respectively, 8.68 and 10.16 USD/m2.

由于墨西哥城都会区大气污染的影响,锌和镀锌钢的大气腐蚀成本映射

摘要

由于大气污染的影响而造成的材料劣化,由于对劣化材料的维护和更换,给社会带来了成本。镀锌钢在电气工业中用于建造输电塔 (ETT)。该研究的目的是估算用于建造 ETT 的镀锌钢的年度维护成本。考虑到材料表面积的成本以及清洁区和污染区的维护间隔之间的差异,估算了镀锌钢的维护成本。获得了镀锌钢(85 和 100 µm)的间隔和维护成本图,这是墨西哥规定的 ETT 厚度。此外,ArcGis 地理信息系统用于人为环境数据的空间表示。2 .
